當使用`FusedLocationApi`時，android在`LocationServices.API`和`Auth.GOOGLE_SIGN_IN_API`之間發生沖突

Question

我有這樣的代碼setGoogleSignInAccount

mGoogleApiClient = new GoogleApiClient.Builder(this)
                .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();

而且我有使用FusedLocationApi這樣獲取位置的代碼

Location mLastLocation = LocationServices.FusedLocationApi.getLastLocation(
                            mGoogleApiClient);

它是可行的，但是現在我的問題是當我單擊注銷錯誤時，因為當我更改為.addApi(Auth.GOOGLE_SIGN_IN_API, gso)時， .addApi(LocationServices.API)可以成功注銷，但是現在FusedLocationApi是錯誤的

和這個logcat當FusedLocationApi錯誤時

Answer 1

當我更改為.addApi（Auth.GOOGLE_SIGN_IN_API，gso）時，注銷成功

不要改變 加。

mGoogleApiClient = new GoogleApiClient.Builder(this)
                .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
                // Add more APIs, as needed
                .build();
