我做了以下工作,但在退出后无法再次登录应用程序
private void signOutFromGplus() {
if (mGoogleApiClient.isConnected()) {
// clearCookies();
Plus.AccountApi
.clearDefaultAccount(mGoogleApiClient);
.mGoogleApiClient.disconnect();
.mGoogleApiClient.connect();
}
}

在此类中为您分配变量(使用此类的优点是此类在启动应用程序时启动,您可以在应用程序的任何位置访问此类): 的 MyApplication.class 强>
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;
}
}
登录活动
@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();
}
在您要退出的第二个活动中
@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application元素中添加这行代码。
android:name=".MyApplication"

这可能是一个老问题,但我想在这里清楚,很可能是第一次登录谷歌的新人。在调用以下方法后,他们可能在自动登录Google帐户时遇到问题。
private void signOutFromGplus() {
if (mGoogleApiClient.isConnected()) {
// clearCookies();
Plus.AccountApi
.clearDefaultAccount(mGoogleApiClient);
.mGoogleApiClient.disconnect();
.mGoogleApiClient.connect();
}
}
解决方案:确保您的mGoogleApiClient尚未在某处断开连接。那么为什么它没有进入这个if循环的原因。
最有可能在onStop()
或onDestroy()
。

Sign-out
和Revoke
之间存在差异。您似乎想要断开用户与应用程序的连接,因此下次再次提示用户登录。如果是这种情况,请尝试以下操作(有关详细信息,请参阅Google+ Sign-in for Android):
// Prior to disconnecting, run clearDefaultAccount().
Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
Plus.AccountApi.revokeAccessAndDisconnect(mGoogleApiClient)
.setResultCallback(new ResultCallback<Status>() {
onResult(Status status) {
// mGoogleApiClient is now disconnected and access has been revoked.
// Trigger app logic to comply with the developer policies
}
});

虽然Google的说明在断开连接()后立即调用connect(),但我遇到了与您相同的问题 - 用户再次登录而没有任何互动。
最后,我完全忽略了指令,并从我的代码中删除了对connect()的调用。适合我。

private void googlePlusLogout() {
if (mGoogleApiClient.isConnected()) {
Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
mGoogleApiClient.disconnect();
mGoogleApiClient.connect();
}
}
尝试按下按钮调用此方法。
