Make new app

TrackDeviceUsage

Make new class called DeviceUsageIntentReceiver extends BroadcastReceiverNote broadcast receivers must complete their execution in 10 seconds. If extensive process is needed, start a thread.In onReceive, addLog.e("GOTIT","Got :"+intent.getAction());Back in main activityAdd member variablepublic DeviceUsageIntentReceiver deviceUsageIntentReceiver = new DeviceUsageIntentReceiver();In onCreate add registerReceiver(deviceUsageIntentReceiver, new IntentFilter("android.intent.action.HEADSET_PLUG")); registerReceiver(deviceUsageIntentReceiver, new IntentFilter("android.intent.action.SCREEN_OFF")); registerReceiver(deviceUsageIntentReceiver, new IntentFilter("android.intent.action.SCREEN_ON")); registerReceiver(deviceUsageIntentReceiver, new IntentFilter

("android.intent.action.ACTION_POWER_DISCONNECTED")); registerReceiver(deviceUsageIntentReceiver, new IntentFilter("android.intent.action.ACTION_POWER_CONNECTED")); registerReceiver(deviceUsageIntentReceiver, new IntentFilter("android.intent.action.USER_PRESENT"));Add new function (this is needed so that when your app dies, the OS is not still trying to send it intents)@Overridepublic void onDestroy() {super.onPause();unregisterReceiver(deviceUsageIntentReceiver);}Run itNote: you might need to set permissions!Try opening the browser and check for screen on/off eventsThey still showHowever, to catch events when your app is not in the foreground, you should use a serviceSlide5

Send information back to Activity

In

TrackDeviceUsageActivity, addpublic DeviceUsageInfoReceiver deviceUsageInfoReceiver = new DeviceUsageInfoReceiver();public class DeviceUsageInfoReceiver extends BroadcastReceiver {@Overridepublic void onReceive(Context context, Intent intent) {Log.e("app","got: "+intent.getExtras().getString("EventName"));} }At the end of DeviceUsageIntentReceiver. onReceive, after Log.e("GOTIT","Got :"+intent.getAction());, addIntent broadcast=new Intent("edu.udel.eleg454.ReceiveDeviceUsageInfo");broadcast.putExtra("EventName", intent.getAction());context.sendBroadcast(broadcast);RunThe activity still receives messages when app is not in the foreground
