在android Q中选择视频时崩溃

Question

我的下面的代码在安卓其他版本中工作正常，但在安卓Q版中选择视频时崩溃。

增加了读和写的权限 我的SDK版本是28.0.2以上的代码可以正常录制视频。

使用下面这段代码来启动意图

    val videoIntent = Intent(Intent.ACTION_PICK) 
    videoIntent.setDataAndType(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, "video/*") 
    videoIntent.putExtra(Intent.EXTRA_ALLOW_MULTIPLE, true) 
    videoIntent.putExtra(Intent.EXTRA_LOCAL_ONLY, true) 
    videoIntent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION) startActivityForResult(videoIntent, 
    GALLERY_VIDEO)

在OnActivityResult中

if (data?.data != null) {
                if (data.clipData != null) {
                    val mClipData = data.clipData
                    for (i in 0 until mClipData!!.itemCount) {
                        val item = mClipData.getItemAt(i)
                        val uri = item.uri
                        val videoPath = fileUtil.getVideoPath(this, uri)
                        if (videoPath != null) {
                            videoList.add(VideoType(videoPath, videoPath))
                        }
                        videoPath?.let { MediaType(it, videoPath, VIDEO) }?.let { mediaUrls.add(it) }
                        videoListAdapter.notifyDataSetChanged()
                    }
                } else {
                    val contentURI = data.data
                    val videoPath = fileUtil.getVideoPath(this, contentURI)
                    val type = videoPath?.let { MediaType(it, contentURI.toString(), VIDEO) }
                    if (videoPath != null) {
                        videoList.add(VideoType(videoPath, videoPath))
                    }
                    videoPath?.let { MediaType(it, videoPath, VIDEO) }?.let { mediaUrls.add(it) }
                    videoListAdapter.notifyDataSetChanged()
                }
            }

getVideoPath方法

fun getVideoPath(context: Context, uri: Uri?): String? {
    val projection = arrayOf(MediaStore.Video.Media.DATA)
    var contentUri = ""
    val cursor =
            context.contentResolver.query(uri!!, projection,
                    null, null, null)
    if (cursor != null) {
        val columnIndex = cursor.getColumnIndexOrThrow(MediaStore.Video.Media.DATA)
        cursor.moveToFirst()
        contentUri = cursor.getString(columnIndex)
        cursor.close()
    }
    return contentUri
}

有同样的问题，设法通过改变ACTION_PICK的意图，并添加额外的标志，如工作。

        Intent i = new Intent(Intent.ACTION_OPEN_DOCUMENT);
        i.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
        i.addFlags(Intent.FLAG_GRANT_PERSISTABLE_URI_PERMISSION);
        i.addCategory(Intent.CATEGORY_OPENABLE);
        i.setDataAndType(MediaStore.Video.Media.EXTERNAL_CONTENT_URI, "video/*");
        ((AppCompatActivity) context).startActivityForResult(i, Utils.VIDEO_GALLERY_REQUEST_CODE);

然后在onActivityResult()中获得一个可持续的权限。

        if (requestCode == Utils.VIDEO_GALLERY_REQUEST_CODE && resultCode == AppCompatActivity.RESULT_OK) {
            final Uri videoUri = data.getData();
            getContentResolver().takePersistableUriPermission(
                    videoUri, Intent.FLAG_GRANT_READ_URI_PERMISSION);
            ((PhotosViewModel) mModel).videoChosen(videoUri);
        }

最后，经过这些改变，我成功地得到了缩略图。

if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.Q) {
    try {
         Bitmap thumbnail =
                    getApplication().getContentResolver().loadThumbnail(
                                    uri, new Size(300, 300), null);

         } catch (IOException e) {}

而且我还能使用

getContentResolver().openInputStream(Uri.parse(videoURI))

以及在videoView中使用URI来播放视频。希望这对你有一点帮助。
