According to Mike Krieger, who is one of the Instagram developers, you can already achieve interaction with documents on Android using Intents. If this is what you need, you should look at the Android document for sharing with intent .

Intent intent = new Intent(Intent.ACTION_SEND);
intent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_WHEN_TASK_RESET);
intent.setType("image/*");
Uri uri = Uri.fromFile(getFileStreamPath(pathToImage));
intent.putExtra(Intent.EXTRA_STREAM, uri);
startActivity(Intent.createChooser(intent, "How do you want to share?"));
