谷歌登录 - 安卓 - 点击时屏幕冻结

Question

我在我的某个应用中使用Google登录。我从这个链接获得了代码 - https://www.androidhive.info/2014/02/android-login-with-google-plus-account-1/

我做的一切都很完美，但每当我点击登录时，应用程序最终会冻结并崩溃。

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线程中调用并使用登录代码，因为您的应用程序线程处于等待状态，直到它从谷歌获得响应。

要解决它，请在单独的线程中写入登录代码，以便在应用程序请求respose时，它不会将主UI线程置于等待状态。这将有助于解决冻结申请的问题。可在此处查看线​​程文档Thread Documentation。

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：

public class GoogleLogin extends AppCompatActivity implements GoogleApiClient.OnConnectionFailedListener{
private GoogleApiClient mGoogleApiClient;
private ProgressDialog mProgressDialog;
private GoogleSignInOptions googleSignInOptions;
private ProgressDialog progressDialog;



@Override
protected void onCreate(Bundle savedInstanceState) {
    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
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) {

}

public static boolean checkPlayServices(Context context) {
    GoogleApiAvailability apiAvailability = GoogleApiAvailability.getInstance();
    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;
