Android image share from internal storage not working

Question

I have a functionality to share a particular image to Instagram, the image is downloaded from HTTP and stored in internal storage. When I try to share the image, it fails doing that.

// Store bitmap to image
String path = context.getFilesDir() + "/MyApp";
File imageFolder = new File(path);

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

File imageFile = new File(path, UUID.randomUUID().toString() + ".jpg");

if (!imageFile.exists()) {
  imageFile.createNewFile();
}

FileOutputStream out = new FileOutputStream(imageFile);
image.compress(Bitmap.CompressFormat.JPEG, 90, out);
out.flush();
out.close();

// Share image
Intent share = new Intent(Intent.ACTION_SEND);
share.setType("image/*");
share.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
share.putExtra(Intent.EXTRA_STREAM, Uri.parse(imageFile.toURI().toString()));
activity.startActivity(Intent.createChooser(share, "Share to"));

It doesn't throw any exception, but when instagram opens it says failed loading image and then gets closed.

In order to use file sharing you need to use a File Provider:

To securely offer a file from your app to another app, you need to configure your app to offer a secure handle to the file, in the form of a content URI. The Android FileProvider component generates content URIs for files, based on specifications you provide in XML

Please check the official documentation for an example
