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

Posted 2021-04-16

我有这样的广播：

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，位置Receiver应该执行requestLocationUpdates（）。这是该方法中的代码：

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)
    {

    }

行LocationServices.FusedLocationApi有问题......我无法弄清楚原因。但这就是日志所说的：

我读了另一篇文章，但我还没有得到如何解决它。任何的想法？

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();
    }

答案

这是你的例外：

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

在使用之前，请确保您的mGoogleApiClient已连接。您可以使用mGoogleApiClient.isConnected()来验证和mGoogleApiClient.connect()连接它。

编辑：

您可以做的另一件事是确保在连接mGoogleApiClient后注册广播。您可以将它放在onConnected回调上。

另一答案

尝试将googleApiClient创建移动到onCreate()。 https://stackoverflow.com/a/29440779/4904995
