You need to set the permissions in the AndroidManifest.xml file add a uses permission and under that class an android:name= *camera*

[Q] Linking Strings between Activities and WebViews

Hello XDA,
So I've not found anyone properly discussing this. If they do, please link me to the page and don't flame
I've been making an app for my school and so far, I've been doing alright. But now I have run into a problem which seems to be very hard to solve for me alone.
Namely, I have an EditText and a Button in one Activity and a WebView as a different Activity.
I'm trying to get the EditText String into the WebView URL (String being variable, Button initiating the WebView), but get a lot of errors, some not even related to that.
I would really appreciate it if someone could have a look at the code and help me with this
MyWebView.java:
Code:
package bas.sie.Antonius;
import android.app.Activity;
import android.os.Bundle;
import android.widget.EditText;
import android.webkit.WebView;
import android.webkit.WebViewClient;
public class MyWebView extends Activity {
WebView mWebView;
EditText mEtxtStudentNum;
static String StudentNumFromHome = bas.sie.Antonius.Home.StudentNum;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.setWebViewClient(new WebViewClient());
mWebView.loadUrl("http://carmelcollegegouda.nl/site_ant/roosters/standaardroosters/Lee1_" + StudentNumFromHome + ".htm");
}
}
Home.java (Homescreen):
Code:
package bas.sie.Antonius;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class Home extends Activity {
Button mBtnStSchedule;
static EditText mEtxtStudentNum;
static final String StudentNum = mEtxtStudentNum.getText().toString();
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button next = (Button) findViewById(R.id.BtnStSchedule);
next.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
Intent myIntent = new Intent(view.getContext(), MyWebView.class);
startActivityForResult(myIntent, 0);
}
});
// TODO Auto-generated method stub
}
}
AntoniusActivity.java (Main):
Code:
package bas.sie.Antonius;
import android.app.TabActivity;
import android.content.Intent;
import android.content.res.Resources;
import android.os.Bundle;
import android.view.KeyEvent;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.TabHost;
public class AntoniusActivity extends TabActivity {
WebView mWebView;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Resources res = getResources(); // Resource object to get Drawables
TabHost tabHost = getTabHost(); // The activity TabHost
TabHost.TabSpec spec; // Resusable TabSpec for each tab
Intent intent; // Reusable Intent for each tab
// Create an Intent to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, Home.class);
// Initialize a TabSpec for each tab and add it to the TabHost
spec = tabHost.newTabSpec("home").setIndicator("Home",
res.getDrawable(R.drawable.ic_tab_home))
.setContent(intent);
tabHost.addTab(spec);
// Do the same for the other tabs
intent = new Intent().setClass(this, External.class);
spec = tabHost.newTabSpec("external").setIndicator("External",
res.getDrawable(R.drawable.ic_tab_external))
.setContent(intent);
tabHost.addTab(spec);
intent = new Intent().setClass(this, Contact.class);
spec = tabHost.newTabSpec("contact").setIndicator("Contact",
res.getDrawable(R.drawable.ic_tab_contact))
.setContent(intent);
tabHost.addTab(spec);
tabHost.setCurrentTab(2);
}
private class HelloWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
}
@Override
public boolean onKeyDown(int keyCode, KeyEvent event) {
if ((keyCode == KeyEvent.KEYCODE_BACK) && mWebView.canGoBack()) {
mWebView.goBack();
return true;
}
return super.onKeyDown(keyCode, event);
}
}
In AntoniusActivity, the private class HelloWebViewClient is underlined with yellow (never used), specifically the bit "HelloWebViewClient".
It's also throwing FC's at startup, and errors in LogCat, but I'll post those later on, as it's 10.30 PM here, and school goes on
Thanks in advance,

Trouble with Service and startForeground()

I have trouble creating a service for a mediaplayer. I would like to have startforeground instead of this as well. But I have no proof of my service running. So I dont know if my code actually works. Can someone help me?
If someone is able to help me completely setting up my service, I may pay €5-10. I received €50 from the company to set up a developer account. So I have €25 left.
I am creating a streaming app for a radio station to listen to the internet stream.
Code:
package jonashendrickx.radioplayer.rgrfm;
import android.app.Service;
import android.content.Intent;
import android.os.Binder;
import android.os.IBinder;
import android.util.Log;
import android.widget.Toast;
public class RadioService extends Service {
private final IBinder mBinder = new RadioBinder();
@Override
public void onCreate() {
Toast.makeText(this, "Let's Go", Toast.LENGTH_SHORT).show();
}
@Override
public IBinder onBind(Intent arg0) {
Log.e("LocalService", "Launched");
return mBinder;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
Log.i("LocalService", "Received start id " + startId + ": " + intent);
return START_STICKY;
}
public class RadioBinder extends Binder {
RadioService getService() {
return RadioService.this;
}
}
}

}
}
}

trouble with startForeground and notification showing.

I have already service up and running. So that is working well. Now I am stuck with startForeground. My notifications dont seem to show so I believe startForeground isnt working as well.
I am developing for API range 10-17
I already tried several tutorials without luck
Is someone willing to help me out?

Where do you call startForeground? I can see just bind.
EDIT: I did not check the zip file as I never download any files if I don't know whether I can trust them. Nothing against you.
EDIT: You could try something like this: (I didn't test it)
Code:
private static final int NOTIFICATION_ID = 7392749; //value doen't matter
@Override
public void runInForeground() {
Notification n = new Notification(R.drawable.ic_launcher, "music is playing", System.currentTimeMillis());
PendingIntent i = PendingIntent.getActivity(this, 0, null, 0);
n.setLatestEventInfo(this, "Music Player", "Playing some music", i);
startForeground(NOTIFICATION_ID, n);
}
EDIT: You could also check out this project: https://github.com/commonsguy/cw-android/tree/master/Notifications/FakePlayer

this is working fine.Anyway if added the below two line end Oncreate method of the main activity it doesn't wait untill the alert dialog finishes.it goes to contact activity .So i don't have chance to select option from alert dialog.how to avoid this situation?
view plaincopy to clipboardprint?
Note: Text content in the code blocks is automatically word-wrapped
Intent contact = new Intent(getApplicationContext(),Contacts.class);
startActivity(contact);

Anyone see what im doing wrong here? im new to java so i dont have a clue..
successfully compiles without a problem but crashes on start, the blue code i have added
Code:
import android.support.v7.app.ActionBarActivity;
import android.support.v7.app.ActionBar;
import android.support.v4.app.Fragment;
import android.os.Bundle;
import android.view.LayoutInflater;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.view.ViewGroup;
import android.os.Build;
[COLOR=DeepSkyBlue]import android.widget.*;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;[/COLOR]
public class MainActivity extends ActionBarActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
if (savedInstanceState == null) {
getSupportFragmentManager().beginTransaction()
.add(R.id.container, new PlaceholderFragment()).commit();
}
[COLOR=DeepSkyBlue] Button startpatching = (Button)findViewById(R.id.start);
startpatching.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
try {
Process proc = Runtime.getRuntime().exec("/data/local/startpatch.sh /");
BufferedReader read = new BufferedReader(new InputStreamReader(
proc.getInputStream()));
try {
proc.waitFor();
} catch (InterruptedException e) {
System.out.println(e.getMessage());
}
while (read.ready()) {
System.out.println(read.readLine());
}
} catch (IOException e) {
System.out.println(e.getMessage());
}}
});
};[/COLOR]
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
int id = item.getItemId();
if (id == R.id.action_settings) {
return true;
}
return super.onOptionsItemSelected(item);
}
/**

*/
public static class PlaceholderFragment extends Fragment {
public PlaceholderFragment() {
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View rootView = inflater.inflate(R.layout.fragment_main, container,

return rootView;
}
}
}
Probably would be wise to include the stack trace...
