当使用`FusedLocationApi`时，android在`LocationServices.API`和`Auth.GOOGLE_SIGN_IN_API`之间发生冲突

Question

我有这样的代码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这样获取位置的代码

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

它是可行的，但是现在我的问题是当我单击注销错误时，因为当我更改为.addApi(Auth.GOOGLE_SIGN_IN_API, gso)时， .addApi(LocationServices.API)可以成功注销，但是现在FusedLocationApi是错误的

和这个logcat当FusedLocationApi错误时

Answer 1

当我更改为.addApi（Auth.GOOGLE_SIGN_IN_API，gso）时，注销成功

不要改变 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();
