我想使用Alarm Manager每分钟显示一次通知,我已经实现了以下代码,它工作正常,但问题是当我从堆栈中删除应用程序服务没有运行时。
我希望保持活力,我在onStartCommand中尝试了 START_STICKY ,并且还使用了 onTaskRemoved ,但它是一样的。
我也尝试使用WakefulIntentService实现,但问题是一样的。我的代码如下。
在MainActivity中
Intent myIntent = new Intent(NotificationDemo.this, MyReceiver.class);
myIntent.putExtra("title", "2 minutes");
Random random = new Random();
int m = random.nextInt(9999 - 1000) + 1000;
Log.d("m::: In Notification", m + "");
myIntent.putExtra("id", m);
pendingIntent = PendingIntent.getBroadcast(NotificationDemo.this, m, myIntent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
// alarmManager.setRepeating(AlarmManager.RTC, System.currentTimeMillis(),alarmManager.Inte pendingIntent);
alarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
SystemClock.elapsedRealtime(),
1 * 60 * 1000,
pendingIntent);
为MyService
public class MyAlarmService extends Service {
private NotificationManager mManager;
@Override
public IBinder onBind(Intent arg0) {
// TODO Auto-generated method stub
return null;
}
@Override
public void onCreate() {
// TODO Auto-generated method stub
super.onCreate();
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
String title = intent.getStringExtra("title");
int id = intent.getIntExtra("id", 0);
mManager = (NotificationManager) this.getApplicationContext().getSystemService(this.getApplicationContext().NOTIFICATION_SERVICE);
Intent intent1 = new Intent(this.getApplicationContext(), MainActivity.class);
Notification notification = new Notification(R.mipmap.ic_launcher, title, System.currentTimeMillis());
intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP | Intent.FLAG_ACTIVITY_CLEAR_TOP);
Log.d("id::", id + "");
PendingIntent pendingNotificationIntent = PendingIntent.getActivity(this.getApplicationContext(), id, intent1, PendingIntent.FLAG_UPDATE_CURRENT);
notification.flags |= Notification.FLAG_AUTO_CANCEL;
// notification.setLatestEventInfo(this.getApplicationContext(), "AlarmManagerDemo", "This is a test message!", pendingNotificationIntent);
NotificationCompat.Builder builder = new NotificationCompat.Builder(MyAlarmService.this);
notification = builder.setContentTitle(title)
.setContentText("Hellooo...")
.setTicker("Good Evening...")
.setSmallIcon(android.R.drawable.ic_btn_speak_now)
.setVibrate(new long[]{1000, 1000, 1000, 100})
.setLights(5, 5, 5)
.setContentIntent(pendingNotificationIntent).build();
mManager.notify(id, notification);
startForeground(1337, notification);
return START_STICKY;
}
@Override
public void onDestroy() {
// TODO Auto-generated method stub
super.onDestroy();
// sendBroadcast(new Intent("IWillStartAuto"));
}
@Override
public void onTaskRemoved(Intent rootIntent) {
super.onTaskRemoved(rootIntent);
// sendBroadcast(new Intent("IWillStartAuto"));
// Intent intent = new Intent(getApplicationContext(),MyReceiver.class);
// sendBroadcast(intent);
}
}
这是我的接收器
public class MyReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
String title = intent.getStringExtra("title");
int id = intent.getIntExtra("id", 0);
Intent service1 = new Intent(context, MyAlarmService.class);
service1.putExtra("title", title);
service1.putExtra("id", id);
context.startService(service1);
}
}
在清单中
<receiver android:name=".MyReceiver">
<!--<intent-filter>
<action android:name="IWillStartAuto"/>
</intent-filter>-->
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</receiver>
<service
android:name=".MyAlarmService"
android:enabled="true"
android:stopWithTask="false" />

您需要在前台开始服务 您在服务OnCreate()方法中遗漏了这些内容。
startForeground(1337, notification);
return START_STICKY;
不要在你的活动或片段onDestroy()方法中停止你的服务。

我在我的手机上用android 6.0测试了这个代码,并且在两者的模拟器上都运行良好,甚至从堆栈中删除了应用程序。
即使删除接收者代码,通知仍然有效。

您可以尝试使用接收器配置process =“:remote”来保持接收器活着。我遇到了这个问题,这是我的解决方案。

您是否尝试过使用任何其他输出语句的代码?通知也是非常晚的,也没有为我解雇 - 我可能会责怪Instant Run,但是你可以尝试用类似Toast的东西替换通知激发代码片段吗?由于Toasts不在服务中工作,也许你可以尝试在服务开始知道它可能已启动并运行时在外部存储目录中创建一个文件?
