Get file size using URI in android

Question

I am working on android video application where I am recording a Video using Camera Intent and taking a video from gallery. When recording video or after selecting video from gallery I want to know the size of my video which I took. I want to make a logic to show a user a toast message if selected Video size is greater then 5MB. I made the bottom logic which is not working and giving me 0 value where I tried to take the size from URI.

Thanks in advance.

My Logic which is not working

java.net.URI juri = new java.net.URI(uri.toString());
        File mediaFile = new File(juri.getPath());
        long fileSizeInBytes = mediaFile.length();
        long fileSizeInKB = fileSizeInBytes / 1024;
        long fileSizeInMB = fileSizeInKB / 1024;

        if (fileSizeInMB > 5) {
            Toast.makeText(this,"Video files lesser than 5MB are allowed",Toast.LENGTH_LONG).show();
            return;
        }

This is my code which I am using to get video from Gallery and to record video.

public void takeVideoFromCamera(){

        File mediaFile =new File(Environment.getExternalStorageDirectory().getAbsolutePath()+ "/myvideo.mp4");

        Intent intent = new Intent(MediaStore.ACTION_VIDEO_CAPTURE);
        Uri videoUri;

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
//            videoUri = FileProvider.getUriForFile(this, this.getApplicationContext().getPackageName() + ".provider", mediaFile);
            videoUri = FileProvider.getUriForFile(this, "i.am.ce.by.ncy.provider", mediaFile);
        } else {
            videoUri  = Uri.fromFile(mediaFile);
        }
        intent.putExtra(MediaStore.EXTRA_OUTPUT, videoUri);
        intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
        intent.putExtra(MediaStore.EXTRA_SIZE_LIMIT, 5491520L);//5*1048*1048=5MB
        intent.putExtra(MediaStore.EXTRA_DURATION_LIMIT,45);
        startActivityForResult(intent, VIDEO_CAPTURE);
    }

    public void takeVideoFromGallery(){
        Intent intent = new Intent();
        intent.setType("video/*");
        intent.setAction(Intent.ACTION_GET_CONTENT);
        long maxVideoSize = 5 * 1024 * 1024; // 10 MB
        intent.putExtra(MediaStore.EXTRA_SIZE_LIMIT, maxVideoSize);
        startActivityForResult(Intent.createChooser(intent,"Select Video"),REQUEST_TAKE_GALLERY_VIDEO);

    }

onActivityResult code

    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        if (resultCode == this.RESULT_OK) {

            switch (requestCode) {
                case VIDEO_CAPTURE:
                        if (resultCode == RESULT_OK) {
                            showVideoImage(data.getData());
// Here I want to know what is the size of my Video File
                        } 
                    break;
                case REQUEST_TAKE_GALLERY_VIDEO:
                    if (resultCode == RESULT_OK) {
                        showVideoGallery(data);
// Here I want to know what is the size of my Video File
                    } 
                    break;
          }

AssetFileDescriptor fileDescriptor = getApplicationContext().getContentResolver().openAssetFileDescriptor(uri , "r");
long fileSize = fileDescriptor.getLength();

I think it gets stream from ContentProvider registered for the uri and asks stream what its length. – Malachiasz Jun 25 '21 at 09:12

Checks AssetFileDescriptor.length
If not found, checks ParcelFileDescriptor.getStatSize implicitly inside AssetFileDescriptor.length
If not found, check MediaStore/ContentResolver if URI has content:// scheme

Should work for file://, content:// schemes. Returns -1L if failed to find:

fun Uri.length(contentResolver: ContentResolver)
        : Long {

    val assetFileDescriptor = try {
        contentResolver.openAssetFileDescriptor(this, "r")
    } catch (e: FileNotFoundException) {
        null
    }
    // uses ParcelFileDescriptor#getStatSize underneath if failed
    val length = assetFileDescriptor?.use { it.length } ?: -1L
    if (length != -1L) {
        return length
    }

    // if "content://" uri scheme, try contentResolver table
    if (scheme.equals(ContentResolver.SCHEME_CONTENT)) {
        return contentResolver.query(this, arrayOf(OpenableColumns.SIZE), null, null, null)
                ?.use { cursor ->
                    // maybe shouldn't trust ContentResolver for size: https://stackoverflow.com/questions/48302972/content-resolver-returns-wrong-size
                    val sizeIndex = cursor.getColumnIndex(OpenableColumns.SIZE)
                    if (sizeIndex == -1) {
                        return@use -1L
                    }
                    cursor.moveToFirst()
                    return try {
                        cursor.getLong(sizeIndex)
                    } catch (_: Throwable) {
                        -1L
                    }
                } ?: -1L
    } else {
        return -1L
    }
}

java.net.URI juri = new java.net.URI(uri.toString());
File mediaFile = new File(juri.getPath());

A Uri is not a File.

showVideoImage(data.getData());

ACTION_VIDEO_CAPTURE does not return a Uri.

Moreover, you already know where the file is. You create a File object in takeVideoFromCamera() and use that for EXTRA_OUTPUT. Hold onto that File object (and also save it in the saved instance state Bundle), then use that for finding out the size of the resulting video.

thanks for your answer and this good explanation. Can you please give me a code snippet in my above code example. It will be really helpful for me. – Usman Khan Mar 21 '18 at 20:15
@CommonWare basically I want to know the resulted Video size in both scenarios, like for takeVideoFromCamera() and for takeVideoFromGallery(). Thanks – Usman Khan Mar 21 '18 at 20:19
@UKhan: [This sample app](https://github.com/commonsguy/cw-omnibus/tree/v8.10/Media/VideoRecordIntent) demonstrates using `ACTION_VIDEO_CAPTURE` with `FileProvider`. I show how to hold onto the `File` and the `Uri` in fields. In my case, I happen to use the `Uri` in `onActivityResult()`, whereas you would use the `File`. – CommonsWare Mar 21 '18 at 20:33

You should close cursor to release resources. – sider Jan 05 '21 at 13:39

This is working for me:

        Uri path = data.getData();
        Cursor returnCursor = getContentResolver().
                query(path, null, null, null, null);
        int sizeIndex = returnCursor.getColumnIndex(OpenableColumns.SIZE);
        returnCursor.moveToFirst();

        int size = returnCursor.getInt(sizeIndex) / 1000;

        returnCursor.close();

        tv_description.setText("size: " + size);

You Can use getInt, getLong etc...

try this

File file = new File(URI);

    if (file.exists()){
        long size = file.length();
    }

the value is = 0 when

the file exists but contained zero bytes. the file does not exist, or the file is some OS-specific special file.
