android - 如何从google plus中的google plus帐户注销以及android中的集成

Question

我做了以下工作，但在注销后它无法正常工作再次快速登录应用程序

private void signOutFromGplus() {

    if (mGoogleApiClient.isConnected()) {

        // clearCookies();

        Plus.AccountApi
                .clearDefaultAccount(mGoogleApiClient);

        .mGoogleApiClient.disconnect();

        .mGoogleApiClient.connect();
    }
}

在这个类中为你分配变量(使用这个类的好处是这个类在应用程序启动时启动，你可以在应用程序的任何地方访问它)如下:MyApplication.class

import android.app.Application;
import android.support.v7.app.AppCompatActivity;
import com.google.android.gms.auth.api.Auth;
import com.google.android.gms.auth.api.signin.GoogleSignInOptions;
import com.google.android.gms.common.api.GoogleApiClient;
public class MyApplication extends Application {
private GoogleApiClient mGoogleApiClient;
private GoogleSignInOptions gso;
public AppCompatActivity activity;
public GoogleSignInOptions getGoogleSignInOptions(){
    gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .build();
    return gso;
}
public GoogleApiClient getGoogleApiClient(AppCompatActivity activity, GoogleApiClient.OnConnectionFailedListener listener){
    this.activity = activity;
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .enableAutoManage(this.activity, listener)
            .addApi(Auth.GOOGLE_SIGN_IN_API, getGoogleSignInOptions())
            .build();
    return mGoogleApiClient;
}
}

在登录 Activity 中

    @Override
protected void onStart() {
    mGoogleApiClient.connect();
    super.onStart();
    OptionalPendingResult<GoogleSignInResult> opr = Auth.GoogleSignInApi.silentSignIn(mGoogleApiClient);
    if (opr.isDone()) {
        Log.d("TAG", "Got cached sign-in");
        GoogleSignInResult result = opr.get();
        handleSignInResult(result);
    } else {
        opr.setResultCallback(new ResultCallback<GoogleSignInResult>() {
            @Override
            public void onResult(GoogleSignInResult googleSignInResult) {
                //hideProgressDialog();
                handleSignInResult(googleSignInResult);
            }
        });
    }
}
@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);

    gso = ((MyApplication) getApplication()).getGoogleSignInOptions();
    mGoogleApiClient = ((MyApplication) getApplication()).getGoogleApiClient(LoginActivity.this, this);
}
@Override
protected void onStop() {
    mGoogleApiClient.disconnect();
    super.onStop();
}

在您要注销的第二个 Activity 中

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_home);

    mGoogleApiClient = ((MyApplication) getApplication()).getGoogleApiClient(HomeActivity.this, this);

btnLogout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Auth.GoogleSignInApi.signOut(mGoogleApiClient).setResultCallback(
                    new ResultCallback<Status>() {
                        @Override
                        public void onResult(Status status) {
                            Intent i = new Intent(HomeActivity.this, LoginActivity.class);
                            startActivity(i);
                            finish();
                        }
                    });
        }
    });
}

在您的应用级 build.gradle 文件中，将 Google Play 服务声明为依赖项:

dependencies {
classpath 'com.android.tools.build:gradle:2.0.0'
classpath 'com.google.gms:google-services:1.5.0-beta2'

让 MyApplication 类扩展默认的 Application 类。另外，打开 Manifest 文件并在应用程序元素中添加这行代码。

android:name=".MyApplication"
