谷歌登录 - 安卓 - 点击时屏幕冻结

Question

我正在我的一个应用中使用 Google 登录。我从这个链接中得到了代码 - https://www.androidhive.info/2014/02/android-login-with-google-plus-account-1/

我完美地完成了所有工作，但是每当我单击"登录"时，应用程序都会冻结并最终崩溃。

似乎无法弄清楚我做错了什么。

这是我的日志：

Answer 2

您正在 MainActivty UI 线程中调用和使用登录代码，因此您的应用程序线程将处于等待状态，直到它得到 google 的响应。

若要解决此问题，请在单独的线程中编写登录代码，以便在应用程序请求 repose 时，它不会将主 UI 线程置于等待状态。这将有助于解决冻结应用程序的问题。线程文档可以在这里看到线程文档。

使用以下代码进行Google登录，它也适用于您自己的自定义按钮：

super.onCreate(savedInstanceState);
googleSignInOptions = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
.requestEmail()
.build();
if(checkPlayServices(this)) {
buildGoogleApiClient(googleSignInOptions);
}
progressDialog=new ProgressDialog(this,R.style.CustomProgressDialog);
LivepoolsUtils.showProgressDialog(this,progressDialog);
if(Validator.isNotNull(mGoogleApiClient)) {
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, Constants.RC_SIGN_IN);
}
}

private void buildGoogleApiClient(GoogleSignInOptions googleSignInOptions) {
if(Validator.isNull(mGoogleApiClient)){
mGoogleApiClient = new GoogleApiClient.Builder(this)
.enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
.addApi(Auth.GOOGLE_SIGN_IN_API, googleSignInOptions)
.build();
}
}
@Override

int resultCode = apiAvailability.isGooglePlayServicesAvailable(context);
if (resultCode != ConnectionResult.SUCCESS)
{
if (apiAvailability.isUserResolvableError(resultCode)) {
apiAvailability.getErrorDialog((GoogleLogin)context, resultCode, Constants.PLAY_SERVICES_RESOLUTION_REQUEST)
.show();
}
return false;
}
return true;
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {

}

Toast.makeText(this,acct.getDisplayName(),Toast.LENGTH_LONG).show();

}
else
