我有密码
@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());
}
当我尝试关闭相机 LED 时，我崩溃了

最佳答案
在某些设备上，如果手电筒被禁用并且您尝试再次禁用它，则应用程序会崩溃。所以解决办法只有切换手电筒的状态。
