我想要为了登录用户我必须使用这段代码：
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient); startActivityForResult(signInIntent,RC_SIGN_IN);
注销@H_301_5@
new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
disconnect();
}
});
解决方法
Here我找到了解决方案：
OptionalPendingResult<GoogleSignInResult> opr = Auth.GoogleSignInApi.silentSignIn(mGoogleApiClient);
if (opr.isDone()) {
// If the user's cached credentials are valid,the OptionalPendingResult will be "done"
// and the GoogleSignInResult will be available instantly.
Log.d(TAG,"Got cached sign-in");
GoogleSignInResult result = opr.get();
handleSignInResult(result);
} else {
// If the user has not prevIoUsly signed in on this device or the sign-in has expired,// this asynchronous branch will attempt to sign in the user silently. Cross-device
// single sign-on will occur in this branch.
showProgressDialog();
opr.setResultCallback(new ResultCallback<GoogleSignInResult>() {
@Override
public void onResult(GoogleSignInResult googleSignInResult) {
hideProgressDialog();
handleSignInResult(googleSignInResult);
}
});
}
