目前,我的应用正在使用

• minSdkVersion 14

• 编译'com.google.android.gms:play-services-gcm:8.4.0'

我使用以下代码来执行GoogleApiClient连接.

public class GoogleApiClientFragment extends Fragment implements
        GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {

    public interface ConnectionCallbacks {
        void onConnected(GoogleApiClient googleApiClient, int action);
        void onCancel(int action);
    }

    public static GoogleApiClientFragment newInstance(String accountName, int action) {
        GoogleApiClientFragment googleApiClientFragment = new GoogleApiClientFragment();
        Bundle bundle = new Bundle();
        bundle.putString(INTENT_EXTRA_ACCOUNT_NAME, accountName);
        bundle.putInt(INTENT_EXTRA_ACTION, action);
        googleApiClientFragment.setArguments(bundle);
        return googleApiClientFragment;
    }

    /**
     * Handles resolution callbacks.
     */
    @Override
    public void onActivityResult(int requestCode, int resultCode,
                                    Intent data) {
        super.onActivityResult(requestCode, resultCode, data); …

我连接GoogleApiClient以用于Google云端硬盘.我像这样构建客户端:

        GoogleApiClient.Builder(this)
                .addApi(Drive.API)
                .addScope(Drive.SCOPE_FILE)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .build();

我的经验是,第一次为此客户端发出连接请求时,会显示AccountPicker对话框并显示Google云端硬盘的同意屏幕.如果用户选择一个帐户,同意并且连接成功完成,则AccountManager或某些相关功能会将所选帐户保存为默认帐户,并将驱动器范围的凭据(OAuth令牌？)保存.在后续连接请求中,为了方便用户,使用保存的值,并且用户没有看到用于帐户选择或同意的UI.

对于开发测试,我希望能够清除默认帐户和保存的凭据,以便我可以执行连接失败解决处理.我还没有办法做到这一点.我尝试了这个没有成功:

String driveScope = "https://www.googleapis.com/auth/drive.file";
String tokenType = "oauth2:" + driveScope;

AccountManager.get(this).invalidateAuthToken(
    GoogleAuthUtil.GOOGLE_ACCOUNT_TYPE, tokenType);
