android - 接收广播 Intent 时出错 { act=android.location.PROVIDERS_CHANGED flg=0x10 }

Question

我的广播是这样的:

private final BroadcastReceiver locationReceiver = new BroadcastReceiver() {
    @Override
    public void onReceive(Context context, Intent intent) {
        if(intent.getAction().matches(LocationManager.PROVIDERS_CHANGED_ACTION)){
            //do stuff
            startLocationUpdates();
        }
    }
};

当用户打开 GPS 时，locationReceiver 应该执行 statLocationUpdates()。这是该方法内的代码:

protected void startLocationUpdates() {
    try
    {
        LocationManager lm = (LocationManager) getSystemService(LOCATION_SERVICE);
        LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, this);
        if(!lm.isProviderEnabled(LocationManager.GPS_PROVIDER))
        {
            buildAlertMessageNoGps();
        }
    }
    catch (SecurityException ex)
    {

    }

LocationServices.FusedLocationApi 线路有问题...我不明白为什么。但这就是日志所说的:

我读了另一篇文章，但我还不知道如何解决它。有什么想法吗？

更新:

我实际上在 onCreate 方法中创建了我的 googleapiclient:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash);
    myContext = this;
    myActivity = this;
    mVisible = true;


    if (mGoogleApiClient == null) {
        mGoogleApiClient = new GoogleApiClient.Builder(myContext)
                .addConnectionCallbacks(ActivitySplash.this)
                .addOnConnectionFailedListener(ActivitySplash.this)
                .addApi(LocationServices.API)
                .build();
    }

Answer 1

这是你的异常(exception):

Caused by: java.lang.IllegalStateException: GoogleApiClient is not connected yet.

使用前请确保您的mGoogleApiClient已连接。您可以使用 mGoogleApiClient.isConnected() 进行验证，并使用 mGoogleApiClient.connect() 进行连接。

编辑:

您可以做的另一件事是确保在连接 mGoogleApiClient 后注册广播。您可以通过将其放在 onConnected 回调中来实现此目的。
