1.This is the class that sends broadcast to main Activity:
public class LecturaDatos extends Service {
inetnt = new Intent(this, MainActivity.class);
sendBroadcast(inetnt);
}
2.This is main Activity and receives the broadcast:
class xReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent1) {
Toast.makeText(context, "Intent Detected.", Toast.LENGTH_LONG).show();
System.out.println("received");
}
}
3.Finally this is my manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.haizea_android"
android:versionCode="1"

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
I don't know why but it doesn't work and I have seen similar problems and tried several solutions but they haven't worked for me
you should set action to your broadcasted intent e.g.
inetnt.setAction("com.javacodegeeks.android.A_CUSTOM_INTENT");

I get this error when I'm trying to start an intent from my wear to my mobile. When I press a button on my watch there's a message send to the listenerservice. And I'm trying to start a method from my listenerService to my MainActivity but I'm getting the error:
java.lang.ClassCastException: android.app.Application cannot be cast to com.my_emergency.samdesmedt.my_emergency.MainActivity
at com.my_emergency.samdesmedt.my_emergency.ListenerServiceFromWear.onMessageReceived(ListenerServiceFromWear.java:28)

This is my ListenerServiceFromWear.Java
#Override

super.onMessageReceived(messageEvent);
if (messageEvent.getPath().equals(WEARPATH)) {
Intent intent = new Intent(this, MainActivity.class);
intent.putExtra("isEmergency", true);
startActivity(intent);
}
}
This is the code in my mainActivity
Intent intent = getIntent();
boolean isEmergency = intent.getBooleanExtra("isEmergency", false);
if(isEmergency){
startEmergencyMode(message);
}
Intent intent = new Intent(getBaseContext(), MainActivity.class);
fixed it
I want to get the called number in android but When I start the outgoing call it fails I am using broadcast receiver and register it in service to keep listen if activity not in focus here is my code.

Have you realized in this line:
Toast.makeText(ctx,
"Inside broadcast",
Toast.LENGTH_LONG).show();
You used ctx instead of context.
Thank to all i have solved the problem my self I was using incorrect context in toaster the correct onReceive is.
I was using ctx which was initialize.
Context ctx;
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "this is not shown" , Toast.LENGTH_LONG).show();
String phoneNumber = intent.getStringExtra(Intent.EXTRA_PHONE_NUMBER);
Toast.makeText(context, "Outgoing call catched: " + phoneNumber, Toast.LENGTH_LONG).show();
}
I have tried this on a few android phones with no luck (i did start the app once).
This was mostly generated from android studio 1.3.2 and from some questions like this and that and the other.
Perhaps someone can point out what i am doing wrong.
Thanks
edit: moved receiver inside app, but no joy.
edit2: added missing permissions for receiver. now seems to work on a nexus 4. but not on the kindle fire or the at&t tablets. although it seems to come right away if i press the circle icon on the azpen.
edit3: seems to work sometimes on the fires now.

Every Component must be declared inside application tag into manifest. Here you declared receiver outside of application tag. Read Structure of the Manifest File.
Correct manifest wil be
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="acme.startup" >
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver
android:name=".BootReceiver"
android:label="BootReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
</application>
</manifest>
You have to add permission to manifest file. Add this before your <application> tag :
<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />
As I understood, if I define configuration activity for widget, onUpdate() method will not call, until I'll not configure it. But in my case, and I wonder why - configuration activity doesn't start, and update method calls after placing widget. My application have other activities, one of them starts when application run, maybe that's is the reason? Here my code:
AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

</receiver>
</application>
<uses-permission xmlns:android="http://schemas.android.com/apk/res/android"

</manifest>
widget_provider.xml
<?xml version="1.0" encoding="utf-8"?>
<appwidget-provider xmlns:android="schemas.android.com/apk/res/android"

public class WidgetConfigureActivity extends Activity {
int widgetId;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setResult(RESULT_CANCELED);
setContentView(R.layout.login_layout);
Intent intent = getIntent();
Bundle extras = intent.getExtras();
if (extras!=null)
widgetId = extras.getInt(AppWidgetManager.EXTRA_APPWIDGET_ID,
AppWidgetManager.INVALID_APPWIDGET_ID);
if (widgetId == AppWidgetManager.INVALID_APPWIDGET_ID) {
finish();
}
Intent resultValue = new Intent();
resultValue.putExtra(AppWidgetManager.EXTRA_APPWIDGET_ID, widgetId);
setResult(RESULT_OK, resultValue);
finish();
}
I am trying to make a GCM client, registration is fine. I am also successfully sending messages from server. However, the client does not start the intent. It says
09-30 08:39:59.795: W/GTalkService(4667): [DataMsgMgr] broadcast intent callback: result=CANCELLED forIntent { act=com.google.android.c2dm.intent.RECEIVE cat=[dol.framework] (has extras) }
My Intent
public class GCMService extends IntentService{
public GCMService(String name) {
super("GCMService");
}
protected void onHandleIntent(Intent intent) {
Bundle extras = intent.getExtras();
String messageType = gcm.getMessageType(intent);
android.util.Log.i("hi","test");
if (!extras.isEmpty()) {
if (GoogleCloudMessaging.MESSAGE_TYPE_MESSAGE.equals(messageType)) {
Logger.logInUI(tag, "Received: " + extras.toString());
}
}
GCMReceiver.completeWakefulIntent(intent);
}
}
And my receiver
public class GCMReceiver extends WakefulBroadcastReceiver {
public void onReceive(Context context, Intent intent) {
ComponentName comp = new ComponentName(context.getPackageName(),
GCMService.class.getName());
startWakefulService(context, (intent.setComponent(comp)));
Logger.log("hi","eetett");
setResultCode(Activity.RESULT_OK);
}
}
And finally my manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

Sorry for the wall of text. Both GCMService and GCMReceiver is at top of my package (dol.framework). What am I doing wrong? Other than those, I am not doing much. Only registering the device and then I am sending a message to this device. Log prints the message at top but does nothing. Shouldn't I start service or something? I didn't see anything related on examples.
In the permission you defined and used for GCM you have dol.framework.gcm.permission. It should be dol.framework.permission, since your app's package is dol.framework.
Try changing the receiver bit of your manifest to this:
<receiver
android:name=".GCMReciever"
android:exported="true"
android:permission="com.google.android.c2dm.permission.SEND" >
<intent-filter>
<action android:name="com.google.android.c2dm.intent.RECEIVE" />
<action android:name="com.google.android.c2dm.intent.REGISTRATION" />
<action android:name="dol.framework" />
</intent-filter>
</receiver>
