Android Studio 中的错误。我有 android 4.4.2 的智能手机,我无法安装更新的。我应该怎么做?
private CameraDevice.StateCallback mCameraDeviceStateCallback = new CameraDevice.StateCallback(){
@Override
public void onOpened(CameraDevice camera){
mCameraDevice = camera;
}
@Override
public void onDisconnected(CameraDevice camera){
camera.close();
mCameraDevice = null;
}
@Override
public void onError(CameraDevice camera, int error){
camera.close();
mCameraDevice = null;
}
};
