我试图设置闹钟以每天在8:30.am重新启动应用程序,所以我设计了服务和接收器,
<receiver android:name=".AlarmReceiver">
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
<action android:name="android.intent.action.SCREEN_ON" />
<action android:name="android.intent.action.SCREEN_OFF" />
</intent-filter>
</receiver>
AlarmReceiver.java
public class AlarmReceiver extends BroadcastReceiver{
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (Intent.ACTION_SCREEN_ON.equals(action)){ //not working ?
Log.d("BootReceiver", "screen on completed");
Intent Alarm = new Intent(context,LongRunningService.class); //start Service
context.startService(Alarm);
}
if (Intent.ACTION_BOOT_COMPLETED.equals(action)){ //not working ?
Log.d("BootReceiver", "system boot completed");
Intent Alarm = new Intent(context,LongRunningService.class); //start Service
context.startService(Alarm);
}
if ("startAlarm".equals(intent.getAction())){
Intent home = new Intent(context, MainActivity.class);
home.putExtra("RELOAD",1);
home.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(home);
}
LongRunningService.java
public int onStartCommand(Intent intent, int flags, int startId) {
new Thread(new Runnable(){
@Override
public void run() {
Log.i(TAG, "run: executed at "+ new Date().toString()); //not working?
}
}).start();
AlarmManager manager = (AlarmManager) getSystemService(ALARM_SERVICE);
// Set the alarm to start at 8:30 a.m.
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(System.currentTimeMillis());
calendar.set(Calendar.HOUR_OF_DAY, 8);
calendar.set(Calendar.MINUTE, 30);
calendar.set(Calendar.SECOND, 00);
}
事实上,我在MainActivity中启动服务,但我不想启动服务
onCrate in MainActivity,因为我的警报设置为8:30来重新启动MainActivity,
将会出现问题,8:30:00〜8:30:30将重复重新启动我的应用程序...。
