非常感谢您的帮助。
编辑：添加了GoogleSignInStatusCodes.getStatusCodeString（result.getStatus（）。getStatusCode（））; 返回10，对应于DEVELOPER_ERROR。
我之前为Google地图创建了一个密钥，它包含在我的项目中（在清单文件中，元标记），现在我是否必须创建另一个密钥？如果是，我该如何包含它？

要调试这个，我会这样做：breakpoint / print来记录你成功登录后从谷歌回来的东西。这将告诉您数据的位置。
下一个活动是什么？看起来你是从谷歌开始做的事情，但开始你自己制作的东西会更有意义。
编辑过去了。一些想法：
googleSignInButton = (SignInButton) findViewById(R.id.sign_in_button);
findViewById(R.id.sign_in_button).setOnClickListener(this);
// Can be done this way:
googleSignInButton = (SignInButton) findViewById(R.id.sign_in_button);
googleSignInButton.setOnClickListener(this);
这就是我做这样的事情：
SignInButton buttonGoogle = (SignInButton) findViewById(R.id.button_google);
assert buttonGoogle != null;
buttonGoogle.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient);
startActivityForResult(signInIntent, RC_SIGN_IN);
}
});
要成功登录Google，您需要以下内容： getResources（）。getString（R.string.google）=＆gt;从strings.xml中获取字符串
/**
* Handling the result from Google.
* @param result You know, tha package.
*/
private void handleSignInResult(GoogleSignInResult result) {
Log.d("handleSignInResult:", "" + result.isSuccess());
if (result.isSuccess()) {
// Signed in successfully, show authenticated UI.
GoogleSignInAccount acct = result.getSignInAccount();
successfulLogin(getResources().getString(R.string.google),
acct.getDisplayName(),
acct.getId(),
acct.getEmail());
} else { // but is never used atm.
String message = String.format(getResources().getString(R.string.communication_signed_out), getResources().getString(R.string.google));
Toast.makeText(getApplicationContext(), message, Toast.LENGTH_SHORT).show();
}
}

尝试以下代码
private void handleSignInResult(GoogleSignInResult result) {
Log.d(String.valueOf(LoginActivity.this), "handleSignInResult:" + result.isSuccess());
if (result.isSuccess()) {
// Signed in successfully, show authenticated UI.
GoogleSignInAccount acct = result.getSignInAccount();
if (acct != null) {
Intent iWelcomeActivity = new Intent(MainActivity.this, WelcomeActivity.class);
iWelcomeActivity.putExtra("USERNAME", acct.getDisplayName());
iWelcomeActivity.putExtra("EMAIL", acct.getEmail();
);
startActivity(iWelcomeActivity);
}
} else {
// Signed out, show unauthenticated UI.
//updateUI(false);
}
}
当用户点击sigin按钮时，意图会提示用户选择要登录的Google帐户。
onActivityResult 方法，检索登录结果并调用handleSignInResult(GoogleSignInResult result)。
如果登录成功，您可以致电getSignInAccount method以获取 GoogleSignInAccount对象，其中包含有关已登录用户的信息。
使用 GoogleSignInAccount对象以acct.getDisplayName(),acct.getEmail()的形式检索信息，并将其传递给下一个活动，如上面的代码所示。
希望它会有所帮助

我遇到同样的错误，直到找到this SO question。问题是如果您没有配置调试版本来使用发布签名密钥，它将使用默认的debugkeystore。如果您已正确设置API密钥，则无法匹配。显然，如果您使用发布签名密钥构建版本.apk，它会起作用，但如果您正在调试（在开发中），您可能忽略了这个过程。
转到 构建＆gt; 编辑构建类型...
在签名选项卡上，创建您的发布签名密钥别名和密钥库的新条目。您可以随意命名，我使用＆＃39; 发布＆＃39;。
现在，在构建类型选项卡上，对于＆＃39; debug＆＃39;构建类型，将签名配置设置为在步骤2中创建的任何内容。
点击 确定，再次再次运行
