尝试关闭相机指示灯时，应用崩溃 [英] When trying turn off camera led, app crash

问题描述

我有一个代码

 @TargetApi(23)
 private void setTorchMode( CameraManager cameraManager, String id, boolean switchOn) throws CameraAccessException {


      try {
            final Method setTorchMode = cameraManager.getClass().getMethod("setTorchMode", String.class, boolean.class);
            cameraManager.setTorchMode(cameraManager.getCameraIdList()[0],switchOn);
            callbackContext.success();
      } catch (IllegalArgumentException m){

      } catch (Throwable t) {
            callbackContext.error(t.getMessage());
      }

当我尝试关闭摄像头的电源时，我崩溃了

推荐答案

在某些设备上，如果手电筒被禁用，而您尝试再次禁用它，则该应用崩溃了。因此解决方案只是切换手电筒的状态。

On some devices, if a flashlight is disabled and you try to disable it again, an app is crashed. So the solution is only to switch the state of the flashlight.
