在 Android Studio 中实施 Google 使用应用程序登录时遇到问题
Trouble Implementing Google Play Sign in with app in Android Studio
我已按照 google 开发者网站上的说明进行操作，但无法正确...
这是我的 MainActivity 中的相关代码片段：
进口：
import com.google.android.gms.common.ConnectionResult;
import com.google.android.gms.common.Scopes;
import com.google.android.gms.common.api.GoogleApiClient;
import com.google.android.gms.common.api.Scope;
import com.google.android.gms.games.Games;
import com.google.android.gms.plus.Plus;
import com.google.example.games.basegameutils.BaseGameUtils;
实现：
public class MainActivity extends Activity implements View.OnTouchListener,
GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener{ ...}
变量：
GoogleApiClient mGoogleApiClient;
private static int RC_SIGN_IN = 9001;
private boolean mResolvingConnectionFailure = false;
private boolean mAutoStartSignInflow = true;
private boolean mSignInClicked = false;
SharedPreferences stats;
SharedPreferences achievements;
SharedPreferences.Editor stat_editor;
SharedPreferences.Editor achievement_editor;
这是实例化的onCreate()
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(Games.API).addScope(Games.SCOPE_GAMES)
.addScope(new Scope(Scopes.PROFILE))
// add other APIs and scopes here as needed
.addApi(Plus.API)
.build();
Activity循环方式：
@Override
protected void onStop() {
super.onStop();
mGoogleApiClient.disconnect();
}
@Override
protected void onStart() {
super.onStart();
mGoogleApiClient.connect();
}
实现的方法：
@Override
public void onConnected(Bundle bundle) {
//hide sign in button
}
@Override
public void onConnectionSuspended(int i) {
// Attempt to reconnect
mGoogleApiClient.connect();
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
if (mResolvingConnectionFailure) {
// already resolving
return;
}
// if the sign-in button was clicked or if auto sign-in is enabled,
// launch the sign-in flow
if (mSignInClicked || mAutoStartSignInflow) {
mAutoStartSignInflow = false;
mSignInClicked = false;
mResolvingConnectionFailure = true;
// Attempt to resolve the connection failure using BaseGameUtils.
// The R.string.signin_other_error value should reference a generic
// error string in your strings.xml file, such as "There was
// an issue with sign-in, please try again later."
if (!BaseGameUtils.resolveConnectionFailure(this,
mGoogleApiClient, connectionResult,
RC_SIGN_IN, getString(R.string.signin_other_error))) {
mResolvingConnectionFailure = false;
}
}
// Put code here to display the sign-in button
}
protected void onActivityResult(int requestCode, int resultCode,
Intent intent) {
if (requestCode == RC_SIGN_IN) {
mSignInClicked = false;
mResolvingConnectionFailure = false;
if (resultCode == RESULT_OK) {
mGoogleApiClient.connect();
} else {
// Bring up an error dialog to alert the user that sign-in
// failed. The R.string.signin_failure should reference an error
// string in your strings.xml file that tells the user they
// could not be signed in, such as "Unable to sign in."
BaseGameUtils.showActivityResultError(this,
requestCode, resultCode, R.string.sign_in_failed);
}
}
}
注意：我目前没有登录按钮，只是想让用户自动提示登录。
应用程序在弹出后一秒崩溃。
我认为可能缺少元标记或权限？目前我只有这些。
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
和
<uses-permission android:name="android.permission.VIBRATE" />
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.USE_CREDENTIALS" />
另一种可能是 google 开发者控制台设置不当。我需要做什么才能让这个东西连接起来？！我搞不清楚了！！谢谢。

此外，我阅读了一些有关生成客户端 ID 并下载 JSON 文件并将其导入您的项目的内容，也许这可能是问题所在？我生成了一个客户端 ID，但没有包含任何 JSON 文件，我该怎么做？
更新
我改为：
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
// add other APIs and scopes here as needed
.addApi(Plus.API)
.build();
删除我原来的这两行：
.addApi(Games.API).addScope(Games.SCOPE_GAMES)
.addScope(new Scope(Scopes.PROFILE))
应用程序在加载时不再崩溃，但仍然没有尝试连接，或者没有弹出 google 登录 window。
我看到你不再有你抱怨的错误，唯一缺少的是连接步骤。尝试添加：
if (mGoogleApiClient.isConnected()) {
Plus.AccountApi.clearDefaultAccount(mGoogleApiClient);
mGoogleApiClient.disconnect();
mGoogleApiClient.connect();
} else if (!mGoogleApiClient.isConnecting()) {
mSignInClicked = true;
// uncomment the next line if you have this method.
// resolveSignInError();
}
给你的 onResume.

我看到你遇到了错误 API_UNAVAILABLE。我想你还没有激活 Google+ API。转到 the official Google tutorial, Step 1。请密切注意第 4 步，确保启用 Google+ API。您需要在这张照片中看到类似的内容。
.
注意 "Disable API" 按钮。这意味着 API 肯定已启用。
还有一件事可能是您的问题的关键。尝试将此权限添加到您的清单
