আমি আমার অ্যাপ্লিকেশনটিতে প্রয়োগ করেছি, পিএসকিঙ্ক থেকে রেফারেস নিয়েছি। অনেক ধন্যবাদ

নীচে @rpgmaker মন্তব্য অনুসারে আমি এই উত্তরটি যুক্ত করেছি
হ্যাঁ আপনি রেজলভইনফো ক্লাস ব্যবহার করে করতে পারেন
আপনার ফাইলটি ইতিমধ্যে ইনস্টল থাকা অ্যাপ্লিকেশনগুলি সমর্থন করে কিনা তা পরীক্ষা করুন
নীচে কোড ব্যবহার:
private boolean isSupportedFile(File file) throws PackageManager.NameNotFoundException {
PackageManager pm = mContext.getPackageManager();
java.io.File mFile = new java.io.File(file.getFileName());
Uri data = Uri.fromFile(mFile);
Intent intent = new Intent(Intent.ACTION_VIEW);
intent.setDataAndType(data, file.getMimeType());
List<ResolveInfo> resolveInfos = pm.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY);
if (resolveInfos != null && resolveInfos.size() > 0) {
Drawable icon = mContext.getPackageManager().getApplicationIcon(resolveInfos.get(0).activityInfo.packageName);
Glide.with(mContext).load("").placeholder(icon).into(binding.fileAvatar);
return true;
} else {
Glide.with(mContext).load("").placeholder(R.drawable.avatar_defaultworkspace).into(binding.fileAvatar);
return false;
