Its difficult and annoying to try to put the Galaxy Gear into bootloader mode. Recovery takes a couple of extra steps. I made a quick wear app that allows for rebooting to Bootloader, Recovery and plain ol' reboot. Google won't allow me to upload API level 20 yet(Android L beta), and my device wont accept API level 19. So, I've attached the apk to this post.

Well...there is one other guy here (aside from me) who is looking on how to root this thing. We both read your post and seen all the work you did, but at the very bottom, someone commented that doing so wouldnt be a wise idea lol. So I THINK we are waiting for see who will take the first shot !

Install TWRP, use that to root your device. Then remove the /System/app/Superuser.apk.
Boot into TWRP
Mount the system
Use the TWRP terminal emulator
rm /system/app/SuperSU.apk
You don't want to use my thread except for the stock firmware flash if you get in a jam.

Start your project
First of all, install eclipse and the android stuff
Then create a new android project, in my case its called com.xda.tutorialscript
Then we need to create the required layout items
Edit res->layout->main.xml
Add a Edittext, Button and TextView
<?xml version=”1.0″ encoding=”utf-8″?>
<LinearLayout xmlns:android=”http://schemas.android.com/apk/res/android”
android:layout_width=”fill_parent”
android:layout_height=”fill_parent”
androidrientation=”vertical” >
<EditText
android:id=”@+input/input1″
android:layout_height=”wrap_content”
android:layout_width=”fill_parent”
/>
<Button
android:id=”@+button/run”
android:layout_height=”wrap_content”
android:layout_width=”wrap_content”
android:text=”Go”
/>
<TextView
android:id=”@+text/text1″
android:layout_width=”fill_parent”
android:layout_height=”wrap_content”
android:text=”Output” />
</LinearLayout>
After that we need to create the code for the root command, bellow there is my version with output treatment and input of a textview to be used as input also, by that you can use the same command on lots of activities and have the output on the textview
// Root Access script runner
void execCommandLine(String command, TextView tv)
{
Runtime runtime = Runtime.getRuntime();
Process proc = null;
OutputStreamWriter osw = null;
// Running the Script
try
{
proc = runtime.exec(“su”);
osw = new OutputStreamWriter(proc.getOutputStream());
osw.write(command);
osw.flush();
osw.close();
}
// If return error
catch (IOException ex)
{
// Log error
Log.e(“execCommandLine()”, “Command resulted in an IO Exception: ” + command);
return;
}
// Try to close the process
finally
{
if (osw != null)
{
try
{
osw.close();
}
catch (IOException e){}
}
}
try
{
proc.waitFor();
}
catch (InterruptedException e){}
// Display on screen if error
if (proc.exitValue() != 0)
{
Log.e(“execCommandLine()”, “Command returned error: ” + command + “\n Exit code: ” + proc.exitValue());
AlertDialog.Builder builder = new AlertDialog.Builder(ScriptrunActivity.this);
builder.setMessage(command + “\nWas not executed sucessfully!”);
builder.setNeutralButton(“OK”, null);
AlertDialog dialog = builder.create();
dialog.setTitle(“Script Error”);
dialog.show();
}
BufferedReader reader = new BufferedReader(
new InputStreamReader(proc.getInputStream()));
int read;
char[] buffer = new char[4096];
StringBuffer output = new StringBuffer();
try {
while ((read = reader.read(buffer)) > 0) {
output.append(buffer, 0, read);
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
String exit = output.toString();
if(exit != null && exit.length() == 0) {
exit = “Command executed Successfully but no output was generated”;
}
tv.setText(exit);
}
After that we have to create a button to grab the text inside the textedit and use as a command
// Button
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button go = (Button) findViewById(R.button.run);
go.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
// Get ID’s
TextView tv = (TextView)findViewById(R.text.text1);
EditText text_id = (EditText)findViewById(R.input.input1);
String input = text_id.getText().toString();
execCommandLine(input, tv);
}
});
A simple explanation of what happens:
The findViewById is used to get the id of the layout item, so we can use it later and by that we declare the textview id ( to be used as input of the execcommand) and button id
Then we get the text from the input1 that is the textedit and transform it to a string to be used in the execCommandLine
And for last we use the execCommandLine
The string input will be used and the output will be transformed from inputstream to string and sent to the textview choosed

}
If you followed the part one here, you know where we left off. In this part of the tutorial, we will be implemeting onCreate in detail, including button clicks and listeners which is a crucial part in playback control.
Let’s start by implemeting add/remove listeners to control the listener attachment. Then implement a small part of onCreate method.
Code:
public void addListener(HwAudioStatusListener listener) {
if (mHwAudioManager != null) {
try {
mHwAudioManager.addPlayerStatusListener(listener);
} catch (RemoteException e) {
Log.e("TAG", "TAG", e);
}
} else {
mTempListeners.add(listener);
}
}
public void removeListener(HwAudioStatusListener listener) { //will be called in onDestroy() method
if (mHwAudioManager != null) {
try {
mHwAudioManager.removePlayerStatusListener(listener);
} catch (RemoteException e) {
Log.e("TAG", "TAG", e);
}
}
mTempListeners.remove(listener);
}
@Override
protected void onDestroy() {
if(mHwAudioPlayerManager!= null && isReallyPlaying){
isReallyPlaying = false;
mHwAudioPlayerManager.stop();
removeListener(mPlayListener);
}
super.onDestroy();
}
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
binding = ActivityMainBinding.inflate(getLayoutInflater());
View view = binding.getRoot();
setContentView(view);
//I set the MainActivity cover image as a placeholder image to cover for those audio files which do not have a cover image.
binding.albumPictureImageView.setImageDrawable(getDrawable(R.drawable.ic_launcher_foreground));
initializeManagerAndGetPlayList(this); //I call my method to set my playlist
addListener(mPlayListener); //I add my listeners
}
If you followed the first part closely, you already have the mTempListeners variable. So, in onCreate, we first initialize everything and then attach our listener to it.
Now that our playlist is programatically ready, if you try to run your code, you will not be able to control what you want because we have not touched our views yet.
Let’s implement our basic buttons first.
Code:
final Drawable drawablePlay = getDrawable(R.drawable.btn_playback_play_normal);
final Drawable drawablePause = getDrawable(R.drawable.btn_playback_pause_normal);
binding.playButtonImageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if(binding.playButtonImageView.getDrawable().getConstantState().equals(drawablePlay.getConstantState())){
if (mHwAudioPlayerManager != null){
mHwAudioPlayerManager.play();
binding.playButtonImageView.setImageDrawable(getDrawable(R.drawable.btn_playback_pause_normal));
isReallyPlaying = true;
}
}
else if(binding.playButtonImageView.getDrawable().getConstantState().equals(drawablePause.getConstantState())){
if (mHwAudioPlayerManager != null) {
mHwAudioPlayerManager.pause();
binding.playButtonImageView.setImageDrawable(getDrawable(R.drawable.btn_playback_play_normal));
isReallyPlaying = false;
}
}
}
});
binding.nextSongImageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (mHwAudioPlayerManager != null) {
mHwAudioPlayerManager.playNext();
isReallyPlaying = true;
}
}
});
binding.previousSongImageView.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
if (mHwAudioPlayerManager != null) {
mHwAudioPlayerManager.playPre();
isReallyPlaying = true;
}
}
});
Do these in your onCreate(…) method. isReallyPlaying is a global boolean variable that I created to keep track of playback. I update it everytime the playback changes. You do not have to have it, as I also tested it with online playlists. I still keep there in case you also want to test your app with online playlists, as in the sample apps provided by Huawei.
For button visual changes, I devised a method like above and I am not asserting that it is the best. You can use your own method but onClicks should rougly be like this.
Now we should implement our listener so that we can track the change in playback. It will also include updating the UI elements, so that the app tracks the audio file changes and seekbar updates. Put this listener outside onCreate(…) method, it will be called anytime it is required. What we should do is to implement necessary methods to respond this calling.
Code:
HwAudioStatusListener mPlayListener = new HwAudioStatusListener() {
@Override
public void onSongChange(HwAudioPlayItem hwAudioPlayItem) {
setSongDetails(hwAudioPlayItem);
if(mHwAudioPlayerManager.getOffsetTime() != -1 && mHwAudioPlayerManager.getDuration() != -1)
updateSeekBar(mHwAudioPlayerManager.getOffsetTime(), mHwAudioPlayerManager.getDuration());
}
@Override
public void onQueueChanged(List list) {
if (mHwAudioPlayerManager != null && list.size() != 0 && !isReallyPlaying) {
mHwAudioPlayerManager.play();
isReallyPlaying = true;
binding.playButtonImageView.setImageDrawable(getDrawable(R.drawable.btn_playback_pause_normal));
}
}
@Override
public void onBufferProgress(int percent) {
}
@Override
public void onPlayProgress(final long currentPosition, long duration) {
updateSeekBar(currentPosition, duration);
}
@Override
public void onPlayCompleted(boolean isStopped) {
if (mHwAudioPlayerManager != null && isStopped) {
mHwAudioPlayerManager.playNext();
}
isReallyPlaying = !isStopped;
}
@Override
public void onPlayError(int errorCode, boolean isUserForcePlay) {
Toast.makeText(MainActivity.this, "We cannot play this!!", Toast.LENGTH_LONG).show();
}
@Override
public void onPlayStateChange(boolean isPlaying, boolean isBuffering) {
if(isPlaying || isBuffering){
binding.playButtonImageView.setImageDrawable(getDrawable(R.drawable.btn_playback_pause_normal));
isReallyPlaying = true;
}
else{
binding.playButtonImageView.setImageDrawable(getDrawable(R.drawable.btn_playback_play_normal));
isReallyPlaying = false;
}
}
};
Now let’s understand the snippet above. Status listener instance wants us to implement some methods shown. They are not required but they will make our lives easier. I will explain the methods inside of them later.
Understanding HwAudioStatusListener
onSongChange is called upon a song change in the queue, i.e. whenever the you skip a song for example, it will be called. Also, it is called for the first time you set the playlist because technically your song changed, from nothing to your index 0 audio file.
onQueueChanged is called upon the queue is altered. I implemented some code just in case but since we will not be dealing with adding/removing items to the playlist and change the queues, it is not very important.
onBufferProgress returns the progress as percentage when you are using online audio.
onPlayProgress is one of the most important method here, everytime the playback is changed, it is called. That is, even the audio files proceed one second (i.e. plays) it will be called. So, it is wise to call UI updates here, rather than dealing with heavy-load fragments, in my opinion.
onPlayCompleted lets you decide the behaviour when the playlist finishes playing. You can restart the playlist, just stop or do something else (like notifying the user that the playlist has ended etc.). It is totally up to you. I restart the playlist in the sample code.
onPlayError is called whenever there is an error occurred in the playback. It could, for example, be that the buffered song is not loaded correctly, format not supported, audio file is corrupted etc. You can handle the result here or you can just notify the user that the file cannot be played; just like I did.
And finally, onPlayStateChange is called whenever the music is paused/re-played. Thus, you can handle the changes here in general. I update isReallyPlaying variable and play/pause button views inside and outside of this method just to be sure. You can update it just here if you want. It should work in theory.
Extra Methods
This listener contains two extra custom methods that I wrote to update the UI and set/render the details of the song on the screen. They are called setSongDetails(…) and updateSeekBar(…). Let’s see how they are implemented.
Code:
public void updateSeekBar(final long currentPosition, long duration){
//seekbar
binding.musicSeekBar.setMax((int) (duration / 1000));
if(mHwAudioPlayerManager != null){
int mCurrentPosition = (int) (currentPosition / 1000);
binding.musicSeekBar.setProgress(mCurrentPosition);
setProgressText(mCurrentPosition);
}
binding.musicSeekBar.setOnSeekBarChangeListener(new SeekBar.OnSeekBarChangeListener() {
@Override
public void onStopTrackingTouch(SeekBar seekBar) {
//Log.i("ONSTOPTRACK", "STOP TRACK TRIGGERED.");
}
@Override
public void onStartTrackingTouch(SeekBar seekBar) {
//Log.i("ONSTARTTRACK", "START TRACK TRIGGERED.");
}
@Override
public void onProgressChanged(SeekBar seekBar, int progress, boolean fromUser) {
if(mHwAudioPlayerManager != null && fromUser){
mHwAudioPlayerManager.seekTo(progress*1000);
}
if(!isReallyPlaying){
setProgressText(progress); //when the song is not playing and user updates the seekbar, seekbar still should be updated
}
}
});
}
public void setProgressText(int progress){
String progressText = String.format(Locale.US, "d:d",
TimeUnit.MILLISECONDS.toMinutes(progress*1000),
TimeUnit.MILLISECONDS.toSeconds(progress*1000) -
TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(progress*1000))
);
binding.progressTextView.setText(progressText);
}
public void setSongDetails(HwAudioPlayItem currentItem){
if(currentItem != null){
getBitmapOfCover(currentItem);
if(!currentItem.getAudioTitle().equals(""))
binding.songNameTextView.setText(currentItem.getAudioTitle());
else{
binding.songNameTextView.setText("Try choosing a song");
}
if(!currentItem.getSinger().equals(""))
binding.artistNameTextView.setText(currentItem.getSinger());
else
binding.artistNameTextView.setText("From the playlist");
binding.albumNameTextView.setText("Album Unknown"); //there is no field assinged to this in HwAudioPlayItem
binding.progressTextView.setText("00:00"); //initial progress of every song
long durationTotal = currentItem.getDuration();
String totalDurationText = String.format(Locale.US, "d:d",
TimeUnit.MILLISECONDS.toMinutes(durationTotal),
TimeUnit.MILLISECONDS.toSeconds(durationTotal) -
TimeUnit.MINUTES.toSeconds(TimeUnit.MILLISECONDS.toMinutes(durationTotal))
);
binding.totalDurationTextView.setText(totalDurationText);
}
else{
//Here is measure to prevent the bad first opening of the app. After user
//selects a song from the playlist, here should never be executed again.
binding.songNameTextView.setText("Try choosing a song");
binding.artistNameTextView.setText("From the playlist");
binding.albumNameTextView.setText("It is at right-top of the screen");
}
}
Remarks
I format the time everytime I receive it because currently AudioKit sends them as miliseconds and the user needs to see in 00:00 format.
I divide by 1000 and while seeking to progress, multiply by 1000 to keep the changes visible on screen. It is also more convenient and accustomed way of implementing seekbars.
I take measure by if checks in case they return null. It should not happen except the first opening but still, as developers, we should be careful.
Please follow comments in the code for additional information.
That’s it for this part. However, we are not done yet. As I mentioned earlier we should also implement the playlist to choose songs from and implement advanced playback controls "); background-size: 1px 1px; background-position: 0px calc(1em + 1px); box-sizing: inherit; font-family: medium-content-serif-font, Georgia, Cambria, "Times New Roman", Times, serif; font-weight: 700; font-size: 18px; text-decoration: underline;">in part 3.

This article covers to draw polylines for different directions types like, Driving, Bicycling and Walking. To get directions response, use OkHttpClient, Volley and Retrofit libraries.
In this article, used Retrofit library to get the response. Check the below code
Code:
private void callDirectionsApi(final String directionType) {
if (!NetworkUtil.isNetworkConnected(this)) {
showNetworkDialog();
return;
}
Origin origin = new Origin();
origin.setLat(13.242430); // Current Location Latitude
origin.setLng(79.277502); // Current Location Longitude
Destination destination = new Destination();
destination.setLat(destinationLocation.getLat());
destination.setLng(destinationLocation.getLng());
DirectionsRequest request = new DirectionsRequest();
request.setOrigin(origin);
request.setDestination(destination);
ApiInterface apiInterface = ApiClient.getClient().create(ApiInterface.class);
Call<DirectionsResponse> call = apiInterface.getDirections(directionType, request);
call.enqueue(new Callback<DirectionsResponse>() {
@Override
public void onResponse(@NotNull Call<DirectionsResponse> call, @NotNull Response<DirectionsResponse> response) {
if (response.isSuccessful()) {
startEndMarkerList = new ArrayList<>();
DirectionsResponse directionsResponse = response.body();
assert directionsResponse != null;
Log.e(TAG + " Response", directionsResponse.toString());
List<RoutesItem> routesItemList = directionsResponse.getRoutes();
if (routesItemList.size() > 0) {
List<StepsItem> steps = routesItemList.get(0).getPaths().get(0).getSteps();
lineLatLngList = new ArrayList<>();
for (StepsItem stepItem : steps) {
List<PolylineItem> polylineItems = stepItem.getPolyline();
for (PolylineItem polylineItem : polylineItems) {
LatLng latLng = new LatLng(polylineItem.getLat(), polylineItem.getLng());
lineLatLngList.add(latLng);
}
}
Iterable<LatLng> latLngIterable = lineLatLngList;
PolylineOptions polyOptions = new PolylineOptions();
if (directionType == "bicycling") {
polyOptions .width(3);
} else if (directionType == "driving") {
polyOptions .width(5);
} else {
List<PatternItem> pattern = Arrays.asList(new Dot(), new Gap(70));
polyOptions .pattern(pattern);
polyOptions .width(7);
}
polyOptions .color(Color.RED);
polyOptions .jointType(ROUND);
directionsPolyline= huaweiMap.addPolyline(polyOptions );
LatLngBounds.Builder builder = new LatLngBounds.Builder();
for (LatLng latLng : latLngIterable) {
builder.include(latLng);
}
LatLngBounds bounds = builder.build();
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngBounds(bounds, 50);
huaweiMap.animateCamera(cameraUpdate);
}
addPolylineCap(lineLatLngList.get(0), R.drawable.grey_circle);
addPolylineCap(lineLatLngList.get(lineLatLngList.size() - 1), R.drawable.white_circle);
addMarkerToMap(destinationLocation, false, destinationName);
animatePolyLine();
}
}
@Override
public void onFailure
(@NotNull Call<DirectionsResponse> call, @NotNull Throwable t) {
Log.e(TAG + " Response Error", Objects.requireNonNull(t.getMessage()));
}
});
}
Dotted and Dashed Polyline:
To draw Dotted and Dashed polyline, following are three classes:
1. Dot
2. Dash
3. Gap
Here based upon directionType changed the width of polyline and for walking path added pattern with new Dot() and new Gap(70) classes.
If we use new Dash() instead of new Dot() we will get dashed polyline.
Code:
if (directionType == "bicycling") {
polyOptions .width(3);
} else if (directionType == "driving") {
polyOptions .width(6);
} else {
List<PatternItem> pattern = Arrays.asList(new Dot(), new Gap(70));
polyOptions .pattern(pattern);
polyOptions .width(10);
}
Polyline Caps:
To add start and end caps for polyline, check the below code.
Code:
addPolylineCap(lineLatLngList.get(0), R.drawable.grey_circle);
addPolylineCap(lineLatLngList.get(lineLatLngList.size() - 1), R.drawable.white_circle);
Instead of adding markers like this, Use default classes for adding caps to polyline, as follows.
1. RoundCap
2. Square Cap
To add this caps to polyline. Check the below code.
Code:
polyOptions.startCap(new RoundCap());
polyOptions.endCap(new CustomCap(getEndCapIcon(Color.BLACK), 100));
Here we can set new RoundCap() and new SquareCap() and also we can give custom cap. Check the below code for adding custom cap.
Code:
public BitmapDescriptor getEndCapIcon(int color) {
// mipmap icon - white arrow, pointing up, with point at center of image
// you will want to create: mdpi=24x24, hdpi=36x36, xhdpi=48x48, xxhdpi=72x72, xxxhdpi=96x96
Drawable drawable = ContextCompat.getDrawable(this, R.mipmap.arrow);
drawable.setBounds(0, 0, drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight());
drawable.setColorFilter(color, PorterDuff.Mode.MULTIPLY);
android.graphics.Bitmap bitmap = android.graphics.Bitmap.createBitmap(drawable.getIntrinsicWidth(), drawable.getIntrinsicHeight(), Bitmap.Config.ARGB_8888);
Canvas canvas = new Canvas(bitmap);
drawable.draw(canvas);
return BitmapDescriptorFactory.fromBitmap(bitmap);
}
Code:
addMarkerToMap(destinationLocation, false, destinationName);
To add custom marker to map. Check my previous article.
Article Link: To customize Maps with Custom Marker and Custom Info Window - Maps Kit
To Animate Polyline like Uber and Swiggy
To animate polylines, Use ValueAnimator to achieve easily. Check the below code.
Code:
private void animatePolyLine() {
ValueAnimator animator = ValueAnimator.ofInt(0, 100);
animator.setDuration(2000);
animator.setInterpolator(new LinearInterpolator());
animator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
@Override
public void onAnimationUpdate(ValueAnimator animator) {
List<LatLng> latLngList = directionsPolyline.getPoints();
int initialPointSize = latLngList.size();
int animatedValue = (int) animator.getAnimatedValue();
int newPoints = (animatedValue * lineLatLngList.size()) / 100;
if (initialPointSize < newPoints) {
latLngList.addAll(lineLatLngList.subList(initialPointSize, newPoints));
directionsPolyline.setPoints(latLngList);
}
}
});
animator.addListener(polyLineAnimationListener);
animator.start();
}
Using AnimatorListener, we can do much more based upon our requirements. Check the below code.
Code:
Animator.AnimatorListener polyLineAnimationListener = new Animator.AnimatorListener() {
@Override
public void onAnimationStart(Animator animator) {
}
@Override
public void onAnimationEnd(Animator animator) {
if (selectedMarker != null) {
selectedMarker.showInfoWindow();
}
}
@Override
public void onAnimationCancel(Animator animator) {
}
@Override
public void onAnimationRepeat(Animator animator) {
}
};

Hi Folks
I will introduce you to how to implement Push Kit both Android side and server side. Also I will show you how to send push notification from backend, catch Android side and open specific page on Android app.
Backend Development
Code:
...
SEND_PUSH_REQUEST_URL = https://push-api.cloud.huawei.com/v1/APP_ID/messages:send
ACCESS_TOKEN_CONTENT = grant_type=client_credentials&client_id=APP_ID&client_secret=APP_SECRET
ACCESS_TOKEN_REQUEST_URL = https://oauth-login.cloud.huawei.com/oauth2/v2/token?grant_type=client_credentials&client_id=APP_ID&client_secret=APP_SECRET
...
There is application.properties class on backend project. There are using to get access token and send notification process. You must get APP_ID and APP_SECRET ‘s values from AGC.
Preparing JSON Object For Notification
Code:
public class PushNotification {
private final Message message;
}
public class Message {
private Android android;
private List<String> token;
}
public class Android {
private int collapse_key;
private String urgency;
private Notification notification;
}
public class Notification {
private String title;
private String body;
private Click_Action click_action;
}
public class Click_Action {
private int type;
private String intent;
}
The classes for create required JSON object on the below.
Code:
public class PushNotificationProcess {
private static final String AUTH = "Authorization";
private static final String METHOD = "POST";
private static final String ACCESS_TOKEN_CONTENT_TYPE = "application/x-www-form-urlencoded";
private static final String CONTENT_TYPE_KEY = "Content-Type";
private static final String SEND_PUSH_CONTENT_TYPE = "application/json";
@Autowired
private Environment environment;
private String accessToken = "";
public void getAccessToken() {
try {
OkHttpClient client = new OkHttpClient();
MediaType mediaType = MediaType.parse(ACCESS_TOKEN_CONTENT_TYPE);
RequestBody body = RequestBody.create(mediaType, environment.getProperty("ACCESS_TOKEN_CONTENT"));
Request request = new Request.Builder()
.url(environment.getProperty("ACCESS_TOKEN_REQUEST_URL"))
.method(METHOD, body)
.addHeader(CONTENT_TYPE_KEY, ACCESS_TOKEN_CONTENT_TYPE)
.build();
client.newCall(request).enqueue(new Callback() {
@Override
public void onResponse(@NotNull Call call, @NotNull Response response) throws IOException {
if (response.isSuccessful()) {
ObjectMapper objectMapper = new ObjectMapper();
ResponseBody responseBody = client.newCall(request).execute().body();
AccessToken entity = objectMapper.readValue(responseBody.string(), AccessToken.class);
accessToken = entity.getToken_type() + " " + entity.getAccess_token();
}
}
@Override
public void onFailure(@NotNull Call call, @NotNull IOException e) {
e.printStackTrace();
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
public void sendPushNotification(String pushBody) {
try {
OkHttpClient client = new OkHttpClient();
MediaType mediaType = MediaType.parse(SEND_PUSH_CONTENT_TYPE);
RequestBody body = RequestBody
.create(mediaType, pushBody);
Request request = new Request.Builder()
.url(environment.getProperty("SEND_PUSH_REQUEST_URL"))
.method(METHOD, body)
.addHeader(AUTH, accessToken)
.addHeader(CONTENT_TYPE_KEY, SEND_PUSH_CONTENT_TYPE)
.build();
client.newCall(request).enqueue(new Callback() {
@Override
public void onResponse(@NotNull Call call, @NotNull Response response) throws IOException {
try {
if (response.isSuccessful()) {
//Success
} else {
//Handler error code
System.out.println(response.code());
}
} catch (Exception e) {
e.printStackTrace();
}
}
@Override
public void onFailure(@NotNull Call call, @NotNull IOException e) {
e.printStackTrace();
System.out.println("onFailure");
}
});
} catch (Exception e) {
e.printStackTrace();
}
}
}
There are 2 functions on the PushNotificationProcess class. The functions about HTTP Request to Huawei Push Kit server. I used OkHttpClient library also you can use Retrofit or something like that. I don’t explain static strings ’cause I think they are clear.
When the calling onResponse method on getAccessToken function, firstly I check response.isSuccesful and then I can get the response body. We must use the access_token like “Baerer xxxx” so I combine token_type and token on the 30. line and the access_token ready to use.
sendPushNotification looks like getAccessToken. I mean there is another HTTP Request. The method has a string param as pushBody -I will explain next part- . I get some strings from application.properties class, you can see 51. line.
Code:
public class PushNotification {
...
private void prepareNotification() {
this.message.setToken(new ArrayList<>());
this.message.getAndroid().setCollapse_key(0);
this.message.getAndroid().setUrgency("NORMAL");
}
public void prepareIntent(int topicId) {
this.message.getAndroid().getNotification().getClick_action().setType(1);
this.message.getAndroid().getNotification().getClick_action()
.setIntent(Constant.DataMessage.SCHEME_URL + Constant.DataMessage.SCHEME_URL_FORUM + topicId + Constant.DataMessage.SCHEME_URL_END);
}
public void prepareContent(String title, String body) {
this.message.getAndroid().getNotification().setTitle(title);
this.message.getAndroid().getNotification().setBody(body);
}
public void prepareTokens(List<String> tokenList) {
this.message.getToken().addAll(tokenList);
}
public String getBodyAsString() {
return new Gson().toJson(this);
}
}
