broadcastreceiver

I want to block the user from changing WiFi, GPS and loading settings from my application. The user need not on/off WiFi and GPS while running my application.(From notification bar). Is there any BroadcastReceiver exist for listening GPS on/off? Well I did a lot of digging and found that addGpsStatusListener(gpsStatusListener) was deprecated in API 24. And for me, this didn't even work! So, here is another alternative solution to this. If in your app, you want to listen to the GPS state change (I mean On/Off by user) . Using a Broadcast surely is the best approach. Implementation: /** *

Okay, so I'm working on an AppWidget that checks the battery level and displays it on a TextView. My code looks like this: public class BattWidget extends AppWidgetProvider { private RemoteViews views = new RemoteViews("com.nickavv.cleanwidgets", R.layout.battlayout); @Override public void onUpdate(Context context, AppWidgetManager appWidgetManager, int appWidgetIds[]) { final int N = appWidgetIds.length; context.getApplicationContext().registerReceiver(this,new IntentFilter(Intent.ACTION_BATTERY_CHANGED)); for (int i = 0; i < N; i++) { int appWidgetId = appWidgetIds[i]; appWidgetManager

I've got my local notifications running on androids prior to SDK 26 But in a Android O I've got the following warning, and the broadcast receiver is not fired. W/BroadcastQueue: Background execution not allowed: receiving Intent { act=package.name.action.LOCAL_NOTIFICATION cat=[com.category.LocalNotification] flg=0x14 (has extras) } to package.name/com.category.localnotifications.LocalNotificationReceiver From what I've read broadcast receivers are more restricted in android O, but if so, how should I schedule the broadcast if I want it launching even if the main activity is not running?

I want to use an alarm to run some code at a certain time. I have successfully implemented an alarm with the broadcast receiver registered in the manifest but the way i understand it, this method uses a separate class for the broadcast receiver. I can use this method to start another activity but I cant use it to run a method in my main activity? ( how can I notify a running activity from a broadcast receiver? ) So I have been trying to register my broadcast receiver in my main activity as explained in the answer above. private BroadcastReceiver receiver = new BroadcastReceiver(){ @Override

How to start an Activity on device even if screen is locked. I tried as below but it's not working. Broadcast receiver: Intent alarmIntent = new Intent("android.intent.action.MAIN"); alarmIntent.setClass(context, Alarm.class); alarmIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); alarmIntent.addFlags(WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED + WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD + WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON + WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON); context.startActivity(alarmIntent); You need the following permission in AndroidManifest.xml file:

I've got an Android application which needs to be woken up sporadically throughout the day. To do this, I'm using the AlarmManager to set up a PendingIntent and have this trigger a BroadcastReceiver. This BroadcastReceiver then starts an Activity to bring the UI to the foreground. All of the above seems to work, in that the Activity launches itself correctly; but I'd like the BroadcastReceiver to notify the Activity that it was started by the alarm (as opposed to being started by the user). To do this I'm trying, from the onReceive() method of the BroadcastReceiver to set a variable in the

AudioManager am = (AudioManager)getSystemService(Context.AUDIO_SERVICE); switch (am.getRingerMode()) { case AudioManager.RINGER_MODE_SILENT: Log.i("MyApp","Silent mode"); break; case AudioManager.RINGER_MODE_VIBRATE: Log.i("MyApp","Vibrate mode"); break; case AudioManager.RINGER_MODE_NORMAL: Log.i("MyApp","Normal mode"); break; } From the code above I can get the ringer mode. What I would liek to do is listen the ringer mode changes and call a function. What I have been told is that I can register the AudioManager. RINGER_MODE_CHANGED_ACTION and listen the change intent in broadcastreceiver
