java - Google 登录仅适用于第一台设备

Question

我在使用 Google 登录时遇到问题，因为第一个登录设备没有问题，但此后的任何设备都会出现“失败”消息。 log cat 中的错误仅显示“signInResult:failed code=10”，我搜索了此错误，找到的一些解决方案是确保 firebase 和 google 具有与我从签名报告中获得的相同的 SHA1 key 。

只是为了确保，我必须放置 SHA1 key 的 google 端是否正确？ https://developers.google.com/identity/sign-in/android/start-integrating .

如果是这样，我已经这样做了，但问题仍然存在。

感谢任何帮助，谢谢

编辑:顺便说一句，这是处理 googlesignin 的代码，经过多次测试，它似乎只能在一台设备上运行，该设备随后收到一条失败消息。

public class SplashScreen extends AppCompatActivity {

int RC_SIGN_IN = 0;
GoogleSignInClient mGoogleSignInClient;
private static int SPLASH_TIME_OUT = 3000;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_splash);


    // Configure sign-in to request the user's ID, email address, and basic
    // profile. ID and basic profile are included in DEFAULT_SIGN_IN.
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .build();

    // Build a GoogleSignInClient with the options specified by gso.
    mGoogleSignInClient = GoogleSignIn.getClient(this, gso);

    signIn();

}

private void signIn() {
    Intent signInIntent = mGoogleSignInClient.getSignInIntent();
    startActivityForResult(signInIntent, RC_SIGN_IN);
}

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    // Result returned from launching the Intent from GoogleSignInClient.getSignInIntent(...);
    if (requestCode == RC_SIGN_IN) {
        // The Task returned from this call is always completed, no need to attach
        // a listener.
        Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
        handleSignInResult(task);
    }
}

private void handleSignInResult(Task<GoogleSignInAccount> completedTask) {
    try {
        GoogleSignInAccount account = completedTask.getResult(ApiException.class);
        // Signed in successfully, show authenticated UI.
        startActivity(new Intent(SplashScreen.this, MainActivity.class));
    } catch (ApiException e) {
        // The ApiException status code indicates the detailed failure reason.
        // Please refer to the GoogleSignInStatusCodes class reference for more information.
        Log.w("Google Sign In Error", "signInResult:failed code=" + e.getStatusCode());
        Toast.makeText(SplashScreen.this, "Failed", Toast.LENGTH_LONG).show();
        final Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                // Do something after 5s = 5000ms
                finish();
                System.exit(0);
            }
        }, 2000);
    }
}

@Override
protected void onStart() {
    // Check for existing Google Sign In account, if the user is already signed in
    // the GoogleSignInAccount will be non-null.
    GoogleSignInAccount account = GoogleSignIn.getLastSignedInAccount(this);
    if(account != null) {
        startActivity(new Intent(SplashScreen.this, MainActivity.class));
    }
    super.onStart();
} }

我解决了这个问题，结果发现我没有在 firebase 的身份验证选项卡中注册谷歌登录。我没有这样做的原因是我遵循的教程没有使用 firebase。我傻了。

编辑:此外，我使用了调试 SHA1 key (我认为是已发布的 key )而不是发布 key 。
