Question

我正在使用Firebase＆amp; Google Play服务允许用户登录我的Android应用。

我完全按照指南操作，但我仍然无法登录，因为每次运行我的应用时，我都会收到RESULT_CANCEL，错误为com.google.android.gms.common.api.ApiException: 12500。

这是我的代码（简化）：

public class MyMainActivity extends Activity {

private final int RC_SIGN_IN = 0;

private FirebaseAuth mAuth;
private FirebaseUser mUser;
private FirebaseStorage mStorage;

private GoogleSignInAccount mAccount;
private GoogleSignInClient mGoogleSignInClient;

private View mDecorView;

private void initUserGoogle() {

    mAccount = GoogleSignIn.getLastSignedInAccount(this);

    if (mAccount != null) return;

    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestIdToken(getString(R.string.server_client_id))
            .build();
    mGoogleSignInClient = GoogleSignIn.getClient(this, gso);
}

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

private void firebaseAuthGoogle(GoogleSignInAccount acct) {

    AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, new OnCompleteListener<AuthResult>() {
                @Override
                public void onComplete(@NonNull Task<AuthResult> task) {
                    if (task.isSuccessful()) {
                        mUser = mAuth.getCurrentUser();
                        mAuthed = true;
                        finish();
                    } else {
                        finish();
                    }
                }
            });
}

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);
    if (hasFocus) {
        mDecorView.setSystemUiVisibility(
                View.SYSTEM_UI_FLAG_LAYOUT_STABLE
                        | View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_HIDE_NAVIGATION
                        | View.SYSTEM_UI_FLAG_FULLSCREEN
                        | View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
    }
}

@Override
protected void onCreate(Bundle savedInstanceState) {

    requestWindowFeature(Window.FEATURE_NO_TITLE);
    getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);

    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_my_main);
    mDecorView = getWindow().getDecorView();

    mAuth = FirebaseAuth.getInstance();

    initUserGoogle();
    signIn();

}

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

    if (requestCode == RC_SIGN_IN) {
        Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
        try {
            mAccount = task.getResult(ApiException.class);
            firebaseAuthGoogle(mAccount);
        } catch (ApiException e) {
            finish();
        }
    }
}

@Override
protected void onDestroy() {
    super.onDestroy();

    FirebaseAuth.getInstance().signOut();
}

}
