Question

正在使用LocationListener GPS和融合API。当应用程序进入后台时获取值。使用服务类和广播接收器并将值保存到共享prefrence.Once禁用并再次启用我没有获得首选项值。请帮我解决实际问题。

1.以下代码适用于BroadcastReciever

public class AlarmReceiver extends BroadcastReceiver {
Context context;

@Override
public void onReceive(Context context, Intent intent) {
    this.context = context;

    System.out.println("Alarm Reciver Called");

    if (isMyServiceRunning(this.context, CurrentTenderServiceFragment.GpsServiceFused.class)) {
        System.out.println("already running no need to start again");
    } else {
        Intent background = new Intent(context, CurrentTenderServiceFragment.GpsServiceFused.class);
        context.startService(background);
    }
}

public static boolean isMyServiceRunning(Context context, Class<?> serviceClass) {
    ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
    List<ActivityManager.RunningServiceInfo> services = activityManager.getRunningServices(Integer.MAX_VALUE);

    if (services != null) {
        for (int i = 0; i < services.size(); i++) {
            if ((serviceClass.getName()).equals(services.get(i).service.getClassName()) && services.get(i).pid != 0) {
                return true;
            }
        }
    }
    return false;
}

}`

我也创建了服务类......

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    super.onStartCommand(intent, flags, startId);
    boolean stopService = false;
    if (intent != null)
        stopService = intent.getBooleanExtra("stopservice", false);
    System.out.println("stopservice " + stopService);
    locationListener = new LocationListener();
    if (stopService)
        stopLocationUpdates();
    else {
        if (!mGoogleApiClient.isConnected())
            mGoogleApiClient.connect();
    }

    return START_STICKY;
}

@Override
public void onCreate() {
    buildGoogleApiClient();
    if (mGoogleApiClient != null) {
        mGoogleApiClient.connect();
    }
    initComponents();
}

清单文件

使用此功能启用和禁用服务

public void enabledBroadcastReceiver() {
    PackageManager pm = DrawerHomeActivity.this.getPackageManager();
    ComponentName componentName = new ComponentName(DrawerHomeActivity.this, AlarmReceiver.class);
    pm.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED,
            PackageManager.DONT_KILL_APP);
    mContext.startService(new Intent(DrawerHomeActivity.this, CurrentTenderServiceFragment.GpsServiceFused.class));
    String alarm = Context.ALARM_SERVICE;
    AlarmManager am = (AlarmManager) getSystemService(alarm);
    Intent intent = new Intent("REFRESH_THIS");
    PendingIntent pi = PendingIntent.getBroadcast(this, 123456789, intent, 0);
    int type = AlarmManager.RTC_WAKEUP;
    long interval = 1000 * 50;
    am.setInexactRepeating(type, System.currentTimeMillis(), interval, pi);
}


  public void disabledBroadcastReceiver() {
    ComponentName receiver = new ComponentName(DrawerHomeActivity.this, AlarmReceiver.class);
    PackageManager pm = DrawerHomeActivity.this.getPackageManager();
    pm.setComponentEnabledSetting(receiver,
            PackageManager.COMPONENT_ENABLED_STATE_DISABLED,
            PackageManager.DONT_KILL_APP);
    mContext.stopService(new Intent(DrawerHomeActivity.this, CurrentTenderServiceFragment.GpsServiceFused.class));
    String alarm = Context.ALARM_SERVICE;
    AlarmManager am = (AlarmManager) getSystemService(alarm);
    Intent intent = new Intent("REFRESH_THIS");
    PendingIntent pi = PendingIntent.getBroadcast(this, 123456789, intent, 0);
    int type = AlarmManager.RTC_WAKEUP;
    long interval = 1000 * 50;
    am.cancel(pi);
    Intent background = new Intent(DrawerHomeActivity.this, AlarmReceiver.class);
    mContext.stopService(background);

}
