我检查了android数据并确定了我的服务的优先级：

Proc # 1: prcp  F/S/FGS  trm: 0 6094:com.package.app/u0a345 (fg-service)

服务由startForegroundService(...启动。我的服务通知设置为：

.setOngoing(true)
...
startForeground(NOTIFICATION_FOREGROUND, builderForegroung.build());

还添加了WakeLock：

public void setWakeMode(Context context, int mode) {
    Log.d("MAIN_SERVICE", "TEST: SET WAKEMODE");
    boolean wasHeld = false;
    if (wakeLock != null) {
        if (wakeLock.isHeld()) {
            wasHeld = true;
            wakeLock.release();
        }
        wakeLock = null;
    }
    PowerManager pm = (PowerManager) context.getSystemService(Context.POWER_SERVICE);
    wakeLock = pm.newWakeLock(mode | PowerManager.ON_AFTER_RELEASE, MainService.class.getName());
    wakeLock.setReferenceCounted(false);
    if (wasHeld) {
        wakeLock.acquire();
    }
}

我不需要任何JobService e.t.c.因为服务具有简单的逻辑。

API 15+上的ForegroundService每15秒杀死一次并重新创建
