Hello,
As my application is running as a service, it uses the BOOT_COMPLETED and USER_PRESENT events to start.
I tested it on different devices running Android 2.x but today I realised it doesn't work on a Google Nexus 3 which runs Icecream Sandwich.
Both booting and unlocking events does not start the application.
I use the following code :
Code:
<receiver
android:enabled="true"
android:name="myapp.StartReceiver">
<intent-filter>
<action android:name = "android.intent.action.BOOT_COMPLETED"/>
<action android:name = "android.intent.action.USER_PRESENT"/>
</intent-filter>
</receiver>
...
public void onReceive(Context context, Intent intent) {
final String action = intent.getAction();
if (Intent.ACTION_BOOT_COMPLETED.equals(action)) {
// ...
Intent service = new Intent(context, MyService.class);
context.startService(service);
} else if (Intent.ACTION_USER_PRESENT.equals(action)) {
// ...
Intent serviceIntent = new Intent(context, MyService.class);
context.startService(serviceIntent);
}
}
So I wonder if it is related to the Android version.
Any idea why it does not work on this specific phone ?
Thank you
Read this.
I guess it is why it doesn't work. Thank you.
Hi everybody!
I am developing an app that (for now) will scan bluetooth devices in the area and it display them on screen. Same thing has to do it with devices that are already associated with the terminal.
Problems:
1) If It start the application with bluetooth off, I get the mythical alert asking me if I want to activate the bluetooth. Confirmed the request, the alert for activate the bluetooth appears and then ... Black screen. Theoretically it should show a list of paired device (in this case, my laptop) but the screen is constantly black (for black i mean that the bar of the name of the app and the Android status bar are showed. The phone doesn't freeze)
2) However, if you start the application with bluetooth turned on, the app crashes and exits.
Any suggestion for solve these problems?
This is the Java Source Code:
Code:
public class Bluetooth extends Activity {
ArrayAdapter<String> mAA;
ListView lv;
private static final int REQUEST_ENABLE_BT = 1;
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.bluetooth);
lv = (ListView) findViewById(R.id.lv);
mAA = new ArrayAdapter<String>(this, R.id.lv);
BluetoothAdapter mBA = BluetoothAdapter.getDefaultAdapter();
if (!mBA.isEnabled()) {
Intent enableBtIntent = new Intent(
BluetoothAdapter.ACTION_REQUEST_ENABLE);
startActivityForResult(enableBtIntent, REQUEST_ENABLE_BT);
}
Set<BluetoothDevice> pairedDevices = mBA.getBondedDevices();
if (pairedDevices.size() > 0) {
for (BluetoothDevice device : pairedDevices) {
mAA.add(device.getName() + "\n" + device.getAddress());
lv.setAdapter(mAA);
}
}
final BroadcastReceiver mReceiver = new BroadcastReceiver() {
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (BluetoothDevice.ACTION_FOUND.equals(action)) {
BluetoothDevice device = intent
.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
mAA.add(device.getName() + "\n" + device.getAddress());
}
}
};
IntentFilter filter = new IntentFilter(BluetoothDevice.ACTION_FOUND);
registerReceiver(mReceiver, filter);
mBA.cancelDiscovery();
lv.setAdapter(mAA);
}
}
Clarification:
- In the manifest i insert the string <uses-permission android:name="android.permission.BLUETOOTH" />
- Layout XML:
HTML:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/ apk /res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<ListView
android:id="@+id/lv"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" >
</ListView>
</LinearLayout>
Thank you in advance for all your help!
... And sorry for my English...
Hello, I am trying to create a broadcast receiver to detect when the screen was locked. I have it already working to detect when the the tablet was booted, but it won't work for the SCREEN_OFF action. Right now I just have it log any intents that where triggered and so far its only working for when the boot was completed.
Code:
package com.atlantis;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
public class broadcastReceiver extends BroadcastReceiver {
[user=439709]@override[/user]
public void onReceive( Context context , Intent intent ) {
Log.v( "atlantis" , "Hey this intent was triggered " + intent );
if ( "android.intent.action.BOOT_COMPLETED".equals(intent.getAction()) ) {
Intent launchMain = new Intent ( context, MainActivityService.class );
context.startService( launchMain );
}
}
}
Android manifest:
Code:
<receiver
android:name = "com.atlantis.broadcastReciever"
android:enabled = "true"
android:exported = "false" >
<intent-filter>
<action android:name = "android.intent.action.ACTION_SCREEN_OFF" />
<action android:name = "android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
Thanks

did you write anything for screen lock intent... if yes display that code..
have an android widget which is actually a button to start an activity.The widget works fine using this code but there is a small bug :
When I add the widget to the home screen , clicking it first time doesn't do anything , second time it works. Then it works normally from 1st click. And the same thing happens when the phone is restarted.Can someone help me solve this problem ??
MyWidgetIntentReceiver.java
public class MyWidgetIntentReceiver extends BroadcastReceiver {

The New Dialog got bigger buttons, so ugly but functionable now.
a conclusion
Now, we get details from the code level.
As a conclusion, vendor limits the 3rd setting changes by control the dialog drawing as following:
just show the editable text value in dialog, no commit buttons in vendor theme in default.
other selection lists in dialog are canceled to show up.
BTW, user APKs installing limits to 5, but can reset simply by clear the package installer's data.
Just debug by jdb, and apply following instruction to check if there is any limits mentioned above for a quick running crack.
Code:
stop in android.app.AlertDialog.setHolatekUi(boolean)
set b = false
