我的广播接收器在Pause()函数上运行良好,但是当我杀死我的应用程序时,我的广播接收器仅在oreo中停止监听,而在其他API级别(而不是oreo)上运行良好。我也将广播接收器注册到清单文件中,也将其注册到我的resume()中。
我的主要活动代码:
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
startService(new Intent(this, BroadcastService.class));
Log.i(TAG, "Started service");
}
@Override
public void onResume() {
super.onResume();
registerReceiver(receiver, new IntentFilter(BroadcastService.COUNTDOWN_BR));
Log.i(TAG, "Registered broacast receiver");
}
这是我的服务班级:
public class BroadcastService extends Service {
private final static String TAG = "BroadcastService";
public static final String COUNTDOWN_BR = "com.codecollapse";
Intent bi = new Intent(COUNTDOWN_BR);
CountDownTimer cdt = null;
@Override
public void onCreate() {
super.onCreate();
Log.i(TAG, "Starting timer...");
cdt = new CountDownTimer(30000, 1000) {
@Override
public void onTick(long millisUntilFinished) {
Log.i(TAG, "Countdown seconds remaining: " + millisUntilFinished / 1000);
bi.putExtra("countdown", millisUntilFinished);
//sendBroadcast(bi);
sendBroadcast(new Intent(getBaseContext(), CountDownReceiver.class).setAction("com.codecollapse").putExtra("countdown",millisUntilFinished));
}
@Override
public void onFinish() {
bi.putExtra("IsFinish",true);
Log.i(TAG, "Timer finished");
}
};
cdt.start();
}
@Override
public void onDestroy() {
cdt.cancel();
Log.i(TAG, "Timer cancelled");
super.onDestroy();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
return START_STICKY;
}
@Override
public IBinder onBind(Intent arg0) {
return null;
}
}
这是我的接收者课程
public class CountDownReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
Toast.makeText(context, "You Poke the service", Toast.LENGTH_SHORT).show();
}
}
这是我的清单文件:
