Android中用Dexter v6.2.3申请RECORD_AUDIO权限遇REQUEST_ONGOING错误求助

我在Android Studio中使用Dexter v6.2.3处理RECORD_AUDIO权限申请时，withErrorListener方法触发了错误，错误信息为REQUEST_ONGOING。已在Manifest.xml中声明该权限，相关代码、依赖配置及Logcat日志如下：

权限申请代码 #

Dexter.withActivity(MainActivity.this).withPermission(android.Manifest.permission.RECORD_AUDIO).withListener(new PermissionListener() {
      @Override
      public void onPermissionGranted(PermissionGrantedResponse permissionGrantedResponse) {
                showSpeechSheetDialog();
            }

            @Override
            public void onPermissionDenied(PermissionDeniedResponse permissionDeniedResponse) {
                if (permissionDeniedResponse.isPermanentlyDenied()) {
                    showCustomDialog("Permission Required", "Record audio permission required to use this feature. You can grant this permission in app settings.", "Cancel",
                            null, "Go to Settings", new View.OnClickListener() {
                                @Override
                                public void onClick(View v) {
                                    dialog.cancel();
                                    Intent intent = new Intent(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
                                    Uri uri = Uri.fromParts("package", getPackageName(), null);
                                    intent.setData(uri);
                                    startActivity(intent);
                                }
                            });
                }
            }

            @Override
            public void onPermissionRationaleShouldBeShown(PermissionRequest permissionRequest, PermissionToken permissionToken) {
                permissionToken.continuePermissionRequest();
            }
        }).withErrorListener(new PermissionRequestErrorListener() {
            @Override
            public void onError(DexterError dexterError) {
                Log.e("Dexter error", dexterError.toString());
            }
        }).check();

Logcat日志 #

问题原因及解决办法 #

REQUEST_ONGOING错误表示当前已有未完成的权限请求在处理中，Dexter不允许同时发起多个权限请求。

解决步骤：

• 排查重复调用：确认权限申请代码是否被多次触发（比如按钮重复绑定点击事件、生命周期方法中重复调用）。如果是点击触发，确保事件只绑定一次，或通过标志位拦截重复请求。
• 添加请求状态标记：在Activity中维护布尔变量标记请求状态，发起前检查，回调完成后重置：

  private boolean isPermissionRequestInProgress = false;
  
  private void requestRecordAudioPermission() {
      if (isPermissionRequestInProgress) {
          return;
      }
      isPermissionRequestInProgress = true;
      Dexter.withActivity(MainActivity.this)
              .withPermission(android.Manifest.permission.RECORD_AUDIO)
              .withListener(new PermissionListener() {
                  @Override
                  public void onPermissionGranted(PermissionGrantedResponse response) {
                      isPermissionRequestInProgress = false;
                      showSpeechSheetDialog();
                  }
  
                  @Override
                  public void onPermissionDenied(PermissionDeniedResponse response) {
                      isPermissionRequestInProgress = false;
                      if (response.isPermanentlyDenied()) {
                          // 原有弹窗逻辑
                      }
                  }
  
                  @Override
                  public void onPermissionRationaleShouldBeShown(PermissionRequest request, PermissionToken token) {
                      token.continuePermissionRequest();
                  }
              })
              .withErrorListener(error -> {
                  isPermissionRequestInProgress = false;
                  Log.e("Dexter error", error.toString());
              })
              .check();
  }
  

• 规避生命周期冲突：避免在onResume这类重复执行的生命周期方法中直接调用权限申请，或添加判断逻辑确保仅在必要时发起请求。
• 确认Dexter初始化：v6.x版本无需手动初始化，若有自定义配置，确保初始化代码仅执行一次（如在Application类中）。
