TransactionTooLargeException even when file size is super small

Question

I keep getting this error when trying share an image file:

java.lang.RuntimeException: android.os.TransactionTooLargeException: data parcel size 1085992 bytes

I assumed a fix for this would be to compress the image even more and that would lessen the size. Here's the function that does this job:

 public static File saveBitmaptoFile(Bitmap bitmap, File pictureFile) {
    FileOutputStream out = null;
    try {
        out = new FileOutputStream(pictureFile);

        // on the next line I'm trying compress the heck out of image.
        bitmap.compress(Bitmap.CompressFormat.JPEG, 1, out);
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        try {
            if (out != null) {
                out.close();
            }
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
    return pictureFile;
}

Here's the share function:

 private void shareToInstagram() {
        String type = "image/png";
        Intent share = new Intent(Intent.ACTION_SEND);
       //saveBitmpatoFile saves an extremely small and compressed file about 5kb in size

        File pictureFile = ImageUtil.saveBitmaptoFile(photo, ImageUtil.getOutputMediaFile());
        Uri imgUri = FileProvider.getUriForFile(mContext,"com.mycompany.myapp", pictureFile);

        share.setType(type);
        share.putExtra(Intent.EXTRA_STREAM, imgUri);
        mContext.startActivity(Intent.createChooser(share, "Share to"));
    }

I don't understand how, even with such extreme compression applied to the picture file, the TransactionTooLarge error still gets thrown, saying that the parcel size has effectively not changed one bit. What's more is when I select to share the file through gmail I see can that the file size is 5kb; I'm way below the buffer size of 1000kb sited in the docs! Anybody knows what could be causing this error to still be getting thrown?

Answer 1

So what it ultimately took resolve this TransactionTooLarge Exception, was to identify the Activity that had its subordinate fragments, views etc adding data parcels to the bundle. Then I ran this code in said Activity:

@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    //Clear the Activity's bundle of the subsidiary fragments' bundles.
    outState.clear();
}

That fixed it for me. Hope this help someone out there!
