我尝试运行此代码，但它说在framworke.jar中找不到一些东西
super.onCreate(savedInstanceState);
CameraManager manager = (CameraManager) getSystemService(Context.CAMERA_SERVICE);
String id = null;
try {
id = manager.getCameraIdList()[0];
} catch (CameraAccessException e) {
e.printStackTrace();
}
try {
manager.setTorchMode(id,true);
} catch (CameraAccessException e) {
e.printStackTrace();
}
但我收到了这个错误，
