我的 android 应用程序在共享 gif 时崩溃

Question

I created a meme share app that takes a random meme from Reddit in Image view and the user has the option to share the meme through other apps. The share function works good with jpg, png, etc file types except gif. The gif appears in the imageView but as soon as I click the share button the app crashes . This only happens in the gif file type

My share Function code. The function name is shareMeme .

private void shareImageandText(Bitmap bitmap) {
        Uri uri = getmageToShare(bitmap);
        Intent intent = new Intent(Intent.ACTION_SEND);

        // putting uri of image to be shared
        intent.putExtra(Intent.EXTRA_STREAM, uri);

        // adding text to share
        intent.putExtra(Intent.EXTRA_TEXT, "Hey! Checkout this cool meme on Reddit");

        // Add subject Here
        intent.putExtra(Intent.EXTRA_SUBJECT, "Try Meme Lelo");

        // setting type to image
        intent.setType("image/*");

        // calling startactivity() to share
        startActivity(Intent.createChooser(intent, "Share Via"));
    }

    // Retrieving the url to share
    private Uri getmageToShare(Bitmap bitmap) {
        File imagefolder = new File(getCacheDir(), "images");
        Uri uri = null;
        try {
            imagefolder.mkdirs();
            File file = new File(imagefolder, "shared_image.png");
            FileOutputStream outputStream = new FileOutputStream(file);
            bitmap.compress(Bitmap.CompressFormat.PNG, 90, outputStream);
            outputStream.flush();
            outputStream.close();
            uri = FileProvider.getUriForFile(this, "com.akki.memelelo.fileprovider", file);
        } catch (Exception e) {
            Toast.makeText(this, "" + e.getMessage(), Toast.LENGTH_LONG).show();
        }
        return uri;
    }


    public void shareMeme(View view) {
        BitmapDrawable bitmapDrawable = (BitmapDrawable) memeImageView.getDrawable();
        Bitmap bitmap = bitmapDrawable.getBitmap();
        shareImageandText(bitmap);
}

Answer 1

BitmapDrawable bitmapDrawable = (BitmapDrawable) memeImageView.getDrawable();

Here you are casting GifDrawable to BitmapDrawable which is leading to crash. For getting Image (as Bitmap Object) this works, but you have to handle GIF separately. possible check what is loaded in ImageView and share content accordingly.

For sharing GIF, save GIF on Internal/External storage and share it's URI with:

"image/gif"

Like this:

Intent shareIntent = new Intent(android.content.Intent.ACTION_SEND);
shareIntent.setType("image/gif");
Uri uri = Uri.fromFile(sharingGifFile);
shareIntent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(shareIntent, "Share Emoji"));
