Android - Thumbnail from video file

Question

I currently have a app where the user click on the floating action button and selects a video file, the file is then saved to a different folder. I want to then show thumbnails of all the video's. I've seen a tutorial series where it is done with MediaStore, but then I can't set the path of the uri.

Can someone please point me in the right direction?

Here is my class to open the gallery and save the video to a different path:

public class Activity extends AppCompatActivity {
    private static final int pick = 100;
    Uri videoUri;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity);

        FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
            openGallery();
            }
        });
    }

    private void openGallery() {
        Intent intent = new Intent(Intent.ACTION_PICK, MediaStore.Video.Media.EXTERNAL_CONTENT_URI);
        startActivityForResult(intent, pick);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == RESULT_OK && requestCode == pick) {
            try
            {
                Log.e("videopath","videopath");
                AssetFileDescriptor videoAsset = getContentResolver().openAssetFileDescriptor(data.getData(), "r");
                FileInputStream fis = videoAsset.createInputStream();
                File root=new File(Environment.getExternalStorageDirectory(),"MYFOLDER");

                if (!root.exists()) {
                    root.mkdirs();
                }

                File file;
                file=new File(root,"android_"+System.currentTimeMillis()+".mp4" );

                FileOutputStream fos = new FileOutputStream(file);

                byte[] buf = new byte[1024];
                int len;
                while ((len = fis.read(buf)) > 0) {
                    fos.write(buf, 0, len);
                }
                fis.close();
                fos.close();
            }
            catch (Exception e)
            {
                e.printStackTrace();
            }
            videoUri = data.getData();
        }
    }
  }

You can use the ThumbnailUtils class in Android for this purpose.

public static Bitmap createVideoThumbnail (String filePath, int kind)

this method returns a bitmap of the video.

First parameter is the filepath, ie the location of the video file to be passed as String.
Second parameter is the kind of bitmap that you need, there are two types:
- MediaStore.Images.Thumbnails.MICRO_KIND which generates thumbnail of size 96 x 96
- MediaStore.Images.Thumbnails.MINI_KIND which generates thumbnail of size 512 x 384.

Eg:

Bitmap thumb = ThumbnailUtils.createVideoThumbnail(filePath, Thumbnails.MINI_KIND);

Here is the API docs for further info[Here].

which location does this thumbnail get saved to? I would like to upload it onto a server. — TwoStarII, Nov 17 '19 at 12:20

You can easily do it with Glide :

Glide.with(context).load(videoPath).asBitmap().into(imageView);
