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
public void onMessageReceived(MessageEvent messageEvent) {
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

This is part of a code that I combine together from google and youtube, to execute "turnOnLed" when the alarm go off. For some reason it doesnt execute and I don't know how to make it work. Can someone help? I've Google it, but no succes.
Thank you.
private void startAlarm(Calendar c)
{
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
if (c.before(Calendar.getInstance()));
{
c.add(Calendar.DATE, 1);
}
Intent intent = new Intent(this, Control.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this,0,intent, 0);
alarmManager.set(AlarmManager.RTC_WAKEUP,c.getTimeInMillis(), pendingIntent);
}
public class Control extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent)
{
turnOnLed(); //method to turn on
}
}

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 made an application that requires alarms to be fired.Alarm Manager works fine when they are scheduled from some activity. Since alarms are deleted when reboot occurs,i have made a boot_Receiver to reschedule the alarms. But the problem is that alarms are not fired when they are scheduled from the bootreceiver class. Please Help..
AlarmManager Class:-
public class NotifyService extends WakefulBroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
Notification_Holder notifholder;
Type t=new TypeToken<Notification_Holder>(){}.getType();
Gson js=new Gson();
notifholder=js.fromJson(intent.getStringExtra("one"),t);
Notification_Creator notifcreator=new Notification_Creator(notifholder.title,notifholder.content,notifholder.cal,context);
notifcreator.create_notification();
}
}
BootReceiver class:-
public class AtBoot extends BroadcastReceiver {
SharedPreferences sharedPreferences;
AlarmManager alarmManager;
Intent x;
PendingIntent pendingIntent;
#Override
public void onReceive(Context context, Intent intent) {
sharedPreferences = context.getSharedPreferences("todoshared", Context.MODE_PRIVATE);
String f = sharedPreferences.getString("todolist", null);
Gson json = new Gson();
alarmManager=(AlarmManager)context.getSystemService(Context.ALARM_SERVICE);
vClass.notes = Notification_Holder.convert_from_jason(f);
x=new Intent(context,NotifyService.class);
pendingIntent=PendingIntent.getService(context,2100,x,0);
alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis(),pendingIntent);
Vibrator vib=(Vibrator)context.getSystemService(Context.VIBRATOR_SERVICE);
if(vib.hasVibrator()) {
vib.vibrate(1500);
}
}
}

I have added the vibrator in AtBoot class t check if it is being called on bootup. And the phone vibrates..This means that the class is being invoked on bootup but the alarm part does not work
I think for HTC you should also add in the IntentFilters
<action android:name="com.htc.intent.action.QUICKBOOT_POWERON"/>
Also, I think it should be
PendingIntent.getBroadcast(context, 2100, x, 0);
and not
PendingIntent.getService(context,2100,x,0);
The problem was that i was using pendingintent.getService() instead of pendingIntent.getBroadcast() as correctly pointed out by Velislava...
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"?>

</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");
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:
