而服务运行更改保险丝的位置设置

问题描述

我在我的应用程序整合位置服务。而对于我使用谷歌的保险丝位置服务。

Hi I am integrating location service in my application. And for that I am using Google's fuse location service.

我的实现如下：

public class LocationNotifyService extends Service implements
        LocationListener,
        GoogleApiClient.ConnectionCallbacks,
        GoogleApiClient.OnConnectionFailedListener {

    protected void createLocationRequest() {
        mLocationRequest = new LocationRequest();
        mLocationRequest.setInterval(INTERVAL);
        mLocationRequest.setFastestInterval(FASTEST_INTERVAL);
        mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
    }

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public void onCreate() {

        //show error dialog if GoolglePlayServices not available
        if (isGooglePlayServicesAvailable()) {
            createLocationRequest();

            mGoogleApiClient = new GoogleApiClient.Builder(this)
                    .addApi(LocationServices.API)
                    .addConnectionCallbacks(this)
                    .addOnConnectionFailedListener(this)
                    .build();
             mGoogleApiClient.connect();
        }
    }

    @Override
    public void onConnected(Bundle bundle) {
        Log.d(TAG, "onConnected - isConnected ...............: " + mGoogleApiClient.isConnected());
        startLocationUpdates();
    }
}

我想实现当我的应用程序运行时我想改变的是 LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY 到 LocationRequest.HIGH_ACCURACY 当应用程序在后台再次将其更改为 PRIORITY_BALANCED_POWER_ACCURACY 。与更新间隔也同样的事情。如果应用程序正在运行，应该经常更新的位置和当它在后台应在一段时间后进行更新。

What I want to achieve is when my application is running I want to change LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY to LocationRequest.HIGH_ACCURACY and when application is in background again change it to PRIORITY_BALANCED_POWER_ACCURACY. Same thing with update interval also. If application running it should update location frequently and when it is in background it should update after some time.

因此​​，在短期，这是一个服务，我想在服务而不需要重新启动该服务运行改变保险丝的位置设置。

So in short this is a service, and I want to change fuse location setting while service is running without restarting the service.

我得到完美的应用程序在前台或后台。唯一的问题是交换机的优先级。

I am perfectly getting application is in foreground or in background. Only problem is to switch priority.

推荐答案

我通过创造新的GoogleApiCLient和新LocationRequest解决我的问题
在onStartCommand（）。

I solved my problem by creating new GoogleApiCLient and new LocationRequestin onStartCommand().

在我的应用程序去背景，我重新开始我的服务，并检查有应用程序是在后台或不和改变根据我的设置它。

When my app going to background I am starting my service again and checking there app is in background or not and changing my setting according to it.

@Override
public int onStartCommand(Intent intent, int flags, int startId) {

    if (isGooglePlayServicesAvailable()) {

        if (!isAppIsInBackground(this)) {

            //stopLocationUpdates();

            mLocationRequest.setInterval(FOREGROUND_INTERVAL);
            mLocationRequest.setFastestInterval(FOREGROUND_INTERVAL);
            mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);

        } else {
            mLocationRequest.setInterval(BACKGROUND_INTERVAL);
            mLocationRequest.setFastestInterval(BACKGROUND_INTERVAL);
            mLocationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);

        }

        mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addApi(LocationServices.API)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .build();

        mGoogleApiClient.connect();
    }

    return super.onStartCommand(intent, flags, startId);
}
