问题 I have been working on an app to respond to received SMS messages (before you complain, I know this has been asked A LOT, but believe me, I can't get it to work at all, and I've tried searching for hours).

May someone help me how would be a way to not only shows the network type when app is launched but shows/detect the event of a network type change? I'm trying for Android 6.0.1

The BroadcastReceiver works fine for getting phone call states (call idle, started ect...), and also for getting the airplane mode switched on and off because the broadcast receiver handles both.

At the time app is being killed, receiver can still be triggered when alarm is executed. However, no notification was shown. What can I do? Alarm function: public static void makeAlarm(Context context,Date date) { Log.i("Alarm", "makeAlarm"); AlarmManager alarmMgr; PendingIntent alarmIntent; alarmMgr = (AlarmManager) context.getSystemService

问题 I have created a lock screen for ICS and it is placed in the frameworks and we can open applications using this. For the user effects I have started an animation when the lock screen is displayed. This animation is started using SCREEN_ON broadcastereceiver. But when the phone is booting up even though I registered broadcastereceiver it is not reaching to onReceive() and the animation is not starting. While phone bootup is taking place I thought that this broadcast is not having higher
