我正在按照Google提供的示例代码将Google plus与android集成. https://github.com/googlesamples/google-services/blob/master/android/signin/app/src/main/java/com/google/samples/quickstart/signin/SignInActivity.java

该代码示例完全正常,直到我添加了一些更改,如下所示.

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
 .requestScopes(new Scope(Scopes.PLUS_LOGIN))
 .requestEmail()
 .build();

mGoogleApiClient = new GoogleApiClient.Builder(this)
 .enableAutoManage(this /* FragmentActivity */, this /* OnConnectionFailedListener */)
 .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
 .build();

signinGoogleBtn = (SignInButton) findViewById(R.id.signingoogleBtn);
signinGoogleBtn.setSize(SignInButton.SIZE_STANDARD);
signinGoogleBtn.setScopes(gso.getScopeArray());

我将Google+范围添加到GoogleSignInOptions以自定义登录按钮.然后GoogleSignInResult和handleSignInResult总是返回false.

if (requestCode == RC_SIGN_IN) {
        GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data);
        handleSignInResult(result);

有人可以帮我解决这个问题吗？

在我的 Android 应用程序中，我有一个闪屏，它会闪烁应用程序的徽标 3 秒钟，然后启动登录活动。这是我的代码：

imgView.postDelayed(new Runnable() {
        @Override
        public void run() {
            final Animation animation = new AlphaAnimation(1, 0);
            animation.setDuration(1000);
            animation.setInterpolator(new LinearInterpolator());
            animation.setRepeatCount(Animation.INFINITE);
            animation.setRepeatMode(Animation.REVERSE);
            imgView.startAnimation(animation);
        }
    }, 3000);
Intent intent = new Intent(SplashscreenActivity.this,LoginActivity.class);
startActivity(intent);

但图像无限闪烁。如何让3秒后停止眨眼？我参考了一些帖子，但无法得到确切的答案。

我写了一个简单的PHP代码连接到mysql服务器,如下所示

    <?php

$username = "root";
$password = "Kepwd";
$hostname = "localhost:81";

//connection to the database
$dbhandle = mysqli_connect($hostname, $username, $password)
  or die("Unable to connect to MySQL");
echo "Connected to MySQL<br>";

 ?>

但这会产生以下错误.我在google和stactoverflow中找到了一些关于此问题的主题.但那些对我没有帮助.请有人帮帮我吗？
