如何获取从Android 10的画廊中选择的视频的路径 [英] How to get the path of a video which is selected from gallery on android 10

问题描述

我尝试了很多片段.这就是我现在正在使用的.我知道MediaStore.Video.Media.DATA已过时.某种程度上，这种方法也适用于android 10，但有时会抛出

I tried lot of snippets. This is what I'm using now. I know that MediaStore.Video.Media.DATA is deprecated.somehow this method is working on android 10 as well but sometimes it throws

android.database.CursorIndexOutOfBoundsException:已请求索引0，大小为0

android.database.CursorIndexOutOfBoundsException: Index 0 requested, with a size of 0

public static String getvideoPath(Context context, Uri uri) {
    try {
        Cursor cursor = context.getContentResolver().query(uri, null, null, null, null);
        cursor.moveToFirst();
        String document_id = cursor.getString(0);
        LogMessage.v("Document Id:: "+document_id);
        if(document_id!=null){
        document_id = document_id.substring(document_id.lastIndexOf(":") + 1);
        cursor.close();
        cursor = context.getContentResolver().query(
                MediaStore.Video.Media.EXTERNAL_CONTENT_URI,
                null, MediaStore.Video.Media._ID + " = ? ", new String[]{document_id}, null);
        cursor.moveToFirst();
        String path = cursor.getString(cursor.getColumnIndex(MediaStore.Video.Media.DATA));
        cursor.close();
        return path;
        }else
            return getPath(context,uri);
    } catch (Exception e) {
        e.printStackTrace();
        return getPath(context,uri);
    }
}

private static String getPath(Context context,Uri uri){
    try {
        String[] proj = { MediaStore.Video.Media.DATA };
        Cursor cursor = context.getContentResolver().query(uri, proj, null, null, null);
        cursor.moveToFirst();
        String document_id = cursor.getString(0);
        return document_id;
