已创建Google帐户登录/注销方法。主要想法是当用户点击
时"使用Google"登录,它会将用户导航到用户个人资料页面,当用户决定登录时,将调用Google注销方法并将用户重新定向回主页。但问题是,当用户单击注销按钮时,会发生以下错误,发生了什么?请帮忙
我附上了以下代码和错误日志

管理进行故障排除并发现一直困扰项目的问题:
初始问题:
<强>解决方案:强>
Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
,因为在用户首次访问应用时没有默认帐户。更新的代码:
mGoogleApiClient= new GoogleApiClient.Builder(this).addApi(Plus.API).
addScope(Plus.SCOPE_PLUS_LOGIN).build();
//DAPO:DEV02-20150110: Invoking of GoogleApiClient and connecting GoogleApiClient
@Override
protected void onStart() {
super.onStart();
// Connect To Drive and Google+
mGoogleApiClient.connect();
}
@Override
protected void onStop(){
super.onStop();
// Disconnect from Drive and Google+
if(mGoogleApiClient.isConnected()){
mGoogleApiClient.disconnect();
}
}
protected void onConnected(Bundle ConnectionHint){
//All Clients are connected
mSignInClicked=false;
Toast.makeText(this, "User is connected!", Toast.LENGTH_LONG).show();
}
/* A helper method to resolve the current ConnectionResult error. */
private void resolveSignInError() {
if (mConnectionResult.hasResolution()) {
try {
mIntentInProgress = true;
startIntentSenderForResult(mConnectionResult.getResolution().getIntentSender(),
RC_SIGN_IN, null, 0, 0, 0);
} catch (SendIntentException e) {
// The intent was canceled before it was sent. Return to the default
// state and attempt to connect to get an updated ConnectionResult.
mIntentInProgress = false;
mGoogleApiClient.connect();
}
}
}

if (requestCode == RC_SIGN_IN) {
if (responseCode != RESULT_OK) {

}
