将云端硬盘范围添加到Android应用会导致NeedPermission错误

Question

我的应用已经可以：

1. 具有Firebase授权的Google登录。
2. 通过Firebase将音频文件上传到Google云。
3. 在音频文件上运行Google Speech to Text API。
4. 将结果文本下载到应用程序。

现在想将音频文件和翻译后的文本从我的设备复制到Google云端硬盘，但无法获得权限/逻辑权限。添加驱动器作用域时，出现UserRecoverableAuthException：NeedPermission错误。

在Google凭据屏幕上和/或在应用代码中添加权限需要做什么？

当前应用代码如下。

 private void setupGoogleAndFirebase() {
    // Configure sign-in to request the user's ID, email address, and basic
    // profile. ID and basic profile are included in DEFAULT_SIGN_IN.
    // Scope is to allow speech to text api to read uploaded gcs audio file
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            // Strings from src/debug/res/values/strings.xml
            .requestIdToken(getString(R.string.web_client_id))
            .build();

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

    mAuth = FirebaseAuth.getInstance();
}

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

    // Result returned from launching the Intent from GoogleSignInApi.getSignInIntent(...);
    if (requestCode == RC_SIGN_IN) {
        Task<GoogleSignInAccount> task = GoogleSignIn.getSignedInAccountFromIntent(data);
        try {
            // Google Sign In was successful, authenticate with Firebase
            GoogleSignInAccount account = task.getResult(ApiException.class);
            firebaseAuthWithGoogle(account);
        } catch (ApiException e) {
            // Google Sign In failed, update UI appropriately
            Log.w(TAG, "Google sign in failed", e);
            updateUI(null);
            displaySignOnErrorDialog(getString(R.string.google_signin_unsuccessful));
        }
    }
}

private void firebaseAuthWithGoogle(final GoogleSignInAccount acct) {
    Log.d(TAG, "firebaseAuthWithGoogle:" + acct.getId());
    showProgressDialog();

    AuthCredential credential = GoogleAuthProvider.getCredential(acct.getIdToken(), null);
    mAuth.signInWithCredential(credential)
            .addOnCompleteListener(this, task -> {
                if (task.isSuccessful()) {
                    // Sign in success, update UI with the signed-in user's information
                    Log.d(TAG, "signInWithCredential:success");
                    FirebaseUser user = mAuth.getCurrentUser();
                    updateUI(user);
                    // get token for passing to jobscheduler for xlat of audio
                    new Oauth2TokenTask().execute(acct.getAccount());
                } else {
                    // If sign in fails, display a message to the user.
                    Log.w(TAG, "signInWithCredential:failure", task.getException());
                    displaySignOnErrorDialog(getString(R.string.firebase_signin_unsuccessful));
                    updateUI(null);
                }
