我正在尝试让我的应用程序为新的Android M权限更改做好准备,并发现了一些奇怪的行为.我的应用程序使用相机意图机制允许用户从相机获取图片.但是在另一个活动中需要使用具有Camera权限的摄像头本身(因为需要这个的库依赖card.io).

但是,当我尝试启动Camera意图时,只需要相机意图的活动中的M我看到以下崩溃(如果我从Manifest中删除了Camera权限,则不会发生这种情况),

我收到了错误 revoked permission android.permission.CAMERA

我在清单上使用相机权限

private void dispatchTakePictureIntent(int actionCode) {

    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

    switch (actionCode) {
        case ACTION_TAKE_PHOTO_B:
            File f = null;

            try {
                f = setUpPhotoFile();
                mCurrentPhotoPath = f.getAbsolutePath();
                takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
            } catch (IOException e) {
                e.printStackTrace();
                f = null;
                mCurrentPhotoPath = null;
            }
            break;

        default:
            break;
    } // switch

    startActivityForResult(takePictureIntent, actionCode);
}

和错误是这样的:
