inspire2无人机拍照

我想拍一张照片然后发送给服务器，但是点击拍照之后会报错Camera is busy or the command is not supported in the Camera's current state，我的无人机没有sd卡，是不是这个原因造成的。

另外，没有sd卡我用官方app可以录视频保存到手机，但是拍照保存不了，如果我要将拍的照片在代码里面直接获取进行发送，如何实现。附上我的代码

public static void takePicture(SettingsDefinitions.CameraMode cameraMode, Boolean isCameraStoringPhoto, Activity activity){
    Camera camera = DJIApplication.getCameraInstance();
    if (camera != null){
        if (cameraMode != SettingsDefinitions.CameraMode.SHOOT_PHOTO){
            setCameraMode(SettingsDefinitions.CameraMode.SHOOT_PHOTO);;
        }
        if (isCameraStoringPhoto){
            Utils.showToast(activity, "正在存储，请稍后", Toast.LENGTH_SHORT);
            return;
        }
        //设置单拍
        camera.setShootPhotoMode(SettingsDefinitions.ShootPhotoMode.SINGLE, new CommonCallbacks.CompletionCallback() {
            @Override
            public void onResult(DJIError djiError) {
                if (djiError == null){
                    camera.startShootPhoto(new CommonCallbacks.CompletionCallback() {
                        @Override
                        public void onResult(DJIError djiError) {
                            Utils.onResultShowToast(djiError, "拍照成功", "拍照失败", activity);
                        }
                    });
                } else {
                    Utils.showToast(activity, djiError.getDescription(), Toast.LENGTH_LONG);
                }
            }
        });
    }
}
