尝试登录Google+时，Google Play服务不可用

Question

我正在尝试在我的应用程序中实现Google+登录，但它不会工作。

每次我点击登录，onConnectionFailed被调用，只要我选择帐户。

谁能告诉我出了什么事?

public class LoginActivity extends ActionBarActivity
    implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener, View.OnClickListener{
/*
Variables
 */
/* Request code used to invoke sign in user interactions. */
private static final int RC_SIGN_IN = 0;
/* Client used to interact with Google APIs. */
private GoogleApiClient mGoogleApiClient;
/* A flag indicating that a PendingIntent is in progress and prevents
 * us from starting further intents.
 */
private boolean mIntentInProgress;
/*
 * True if the sign-in button was clicked.  When true, we know to resolve all
 * issues preventing sign-in without waiting.
 */
private boolean mSignInClicked;
/*

 */
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_login);
    mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(Plus.API, Plus.PlusOptions.builder().build())
            .addScope(Plus.SCOPE_PLUS_LOGIN)
            .build();
    // Sign in button click listener
    findViewById(R.id.googleSignInButton).setOnClickListener(this);
}
@Override
protected void onStart() {
    super.onStart();
    mGoogleApiClient.connect();
}
@Override
protected void onStop() {
    super.onStop();
    if (mGoogleApiClient.isConnected()) {
        mGoogleApiClient.disconnect();
    }
}
/*

 */
@Override
public void onClick(View v) {
    if (v.getId() == R.id.googleSignInButton && !mGoogleApiClient.isConnecting()) {
        mSignInClicked = true;
        mGoogleApiClient.connect();
    }
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
    Log.i("TAG", "onConnectionFailed");
    if (!mIntentInProgress) {
        if (mSignInClicked && connectionResult.hasResolution()) {
            // The user has already clicked 'sign-in' so we attempt to resolve all
            // errors until the user is signed in, or they cancel.
            try {
                connectionResult.startResolutionForResult(this, RC_SIGN_IN);
                mIntentInProgress = true;
            } catch (IntentSender.SendIntentException e) {
                // The intent was canceled before it was sent.  Return to the default
                // state and attempt to connect to get an updated ConnectionResult.
                mIntentInProgress = false;
                mGoogleApiClient.connect();
            }
        }
    }
}
@Override
public void onConnected(Bundle bundle) {
    Log.i("TAG", "onConnected");
    mSignInClicked = false;
    Toast.makeText(this, "User is connected!", Toast.LENGTH_LONG).show();
}
@Override
public void onConnectionSuspended(int i) {
    Log.i("TAG", "onConnectionSuspended");
    mGoogleApiClient.connect();
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == RC_SIGN_IN) {
        if (resultCode != RESULT_OK) {
            mSignInClicked = false;
        }
        mIntentInProgress = false;
        if (!mGoogleApiClient.isConnected()) {
            mGoogleApiClient.reconnect();
        }
    }
}
}

我甚至下载了官方的谷歌样本登录，我得到同样的错误。它就是不能登录和连接。

我有良好的连接(甚至wifi)，我尝试了多部手机

这可能是您正在使用的密钥的问题。转到您的google api的控制台尝试生成一个新的客户idSHA1从调试中获得。keystore，然后重试Login。我相信这会帮你解决问题的。
