Get Video Thumbnail from Uri

Question

I want to select a video from my Gallery. It's working fine. But now I want to display a Bitmap, as a thumbnail.I tired this code it's not working, it always says: NullPointerException

Bitmap bitmap2 = ThumbnailUtils.createVideoThumbnail(uri.getPath, MediaStore.Video.Thumbnails.MICRO_KIND);

This is all in an onActivityResult.

How can I get the Bitmap from the video Uri??

Thanks for your help

Answer 1

in onActivityResult

String[] filePathColumn = {MediaStore.Images.Media.DATA};
Cursor cursor = context.getContentResolver().query(uri, filePathColumn, null, null, null);
cursor.moveToFirst();
int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
String picturePath = cursor.getString(columnIndex);
cursor.close();

Bitmap bitmap = ThumbnailUtils.createVideoThumbnail(picturePath, MediaStore.Video.Thumbnails.MICRO_KIND);

Edit

Kotlin version

val filePathColumn = arrayOf(MediaStore.Images.Media.DATA)
val cursor = context.contentResolver.query(uri, filePathColumn, null, null, null)
cursor.moveToFirst()

val columnIndex = cursor.getColumnIndex(filePathColumn[0])
val picturePath = cursor.getString(columnIndex)
cursor.close()

val bitmap = ThumbnailUtils.createVideoThumbnail(picturePath, MediaStore.Video.Thumbnails.MICRO_KIND)
