I'm running a demo example of cwac-locpoll. It is meant to log my position every minute in LocationLog.txt file. It works fine as long as app is on the screen, but if I press the home button it stops logging and when I return to application it reloads again. The same thing happend when I locked screen when it was running on screen, but I forced the app from sleeping with:
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
This, however did not solve the problem with running in background while I'm running other apps on the device. The device I'm using is Huawei Honor 7
The whole code of my MainActivity is as follows:
public class MainActivity extends AppCompatActivity {
private static final int PERIOD= 1000 * 60 * 1; // 1 minute
private PendingIntent pi=null;
private AlarmManager mgr=null;
PowerManager pm;
PowerManager.WakeLock wl;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
final TextView test = (TextView) findViewById(R.id.testTV);
FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
fab.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View view) {
Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
.setAction("Action", null).show();
}
});
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD);
mgr=(AlarmManager)getSystemService(ALARM_SERVICE);
Intent i=new Intent(this, LocationPoller.class);
i.putExtra(LocationPoller.EXTRA_INTENT,
new Intent(this, LocationReceiver.class));
i.putExtra(LocationPoller.EXTRA_PROVIDER,
LocationManager.GPS_PROVIDER);
pi=PendingIntent.getBroadcast(this, 0, i, 0);
mgr.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime(),
PERIOD,
pi);
Toast
.makeText(this,
"Location polling every 1 minutes begun",
Toast.LENGTH_LONG)
.show();
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
