android - 如何在节电程序在android上杀死它后重新启动粘性服务

Question

我尝试通过设置 android:isolatedProcess="true" 但它不起作用

其实我想一直显示永久通知

NotificationCompat.Builder mBuilder = new NotificationCompat.Builder(context)

.setLargeIcon(BitmapFactory.decodeResource(context.getResources(), resourceIcon/*R.mipmap.ic_launcher*/))
                .setSmallIcon(R.drawable.ic_icon_flo_not)
                .setContentTitle(title)
                .setOngoing(onGoing)
                .setAutoCancel(autoCancelable)
                .setPriority(priority)
                .setContentText(message);
        Uri soundUri = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);
        if (playSound)
            mBuilder.setSound(soundUri);
        if (remoteViews == null) {
            // Creates an explicit intent for an Activity in your app
            Intent resultIntent = new Intent(context, resultClass);
            resultIntent.setAction(action);

            // The stack builder object will contain an artificial back stack for the
            // started Activity.
            // This ensures that navigating backward from the Activity leads out of
            // your application to the Home screen.
            TaskStackBuilder stackBuilder = TaskStackBuilder.create(context);
            // Adds the back stack for the Intent (but not the Intent itself)
            stackBuilder.addParentStack(MainActivity.class);
            // Adds the Intent that starts the Activity to the top of the stack
            stackBuilder.addNextIntent(resultIntent);
            PendingIntent resultPendingIntent = stackBuilder.getPendingIntent(0, PendingIntent.FLAG_UPDATE_CURRENT);
            mBuilder.setContentIntent(resultPendingIntent);
        } else {
            mBuilder.setContent(remoteViews);
        }

在您的服务中覆盖 onTaskRemoved() 并使用警报管理器再次启动服务。下面是代码。

    @Override
public void onTaskRemoved(Intent rootIntent) {
    super.onTaskRemoved(rootIntent);

    Log.d(TAG, "TASK REMOVED");

    PendingIntent service = PendingIntent.getService(
            getApplicationContext(),
            1001,
            new Intent(getApplicationContext(), MyService.class),
            PendingIntent.FLAG_ONE_SHOT);

    AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
    alarmManager.set(AlarmManager.ELAPSED_REALTIME_WAKEUP, 1000, service);
}
