আমি একটি ইউআরআই থেকে পুরো ফাইলের পথ পেতে চাই। ইউআরআই কোনও চিত্র নয়, এটি একটি মিউজিক ফাইল, তবে আমি যদি এটি মিডিয়া স্টোর সলিউশনটির মতো করে করি তবে অ্যাপ্লিকেশন ব্যবহারকারী মিউজিক প্লেয়ারের পরিবর্তে যেমন অ্যাস্ট্রোটিকে ব্রাউজার হিসাবে নির্বাচন করে তবে এটি কাজ করবে না। আমি কীভাবে এটি সমাধান করব?
উত্তর:
ব্যবহার:
String path = yourAndroidURI.uri.getPath() // "/mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));
বা
String path = yourAndroidURI.uri.toString() // "file:///mnt/sdcard/FileName.mp3"
File file = new File(new URI(path));
content://বা অন্য কোনও ফাইলবিহীন উরি হয়।
পাথ ইউটিল পদ্ধতিটি কেবলমাত্র ওরিওর নীচে কাজ করবে এবং এটি যদি ওরিওর থেকে ক্রাশ হওয়ার সম্ভাবনা বেশি থাকে তবে ওরিওতে আমরা আইডিটি পাব না তবে ডেটা.ট্যাটাটা () তে পুরো পথটি পাবে তাই আপনাকে যা করতে হবে তা একটি ফাইল তৈরি করতে হবে ইউরি থেকে এবং গেটপথ () থেকে তার পথটি পান এবং এটি ভাগ করুন bel
Uri uri = data.getData();
File file = new File(uri.getPath());//create path from uri
final String[] split = file.getPath().split(":");//split the path.
filePath = split[1];//assign it to a string(your choice).
উপরের কোডটি ওরিওতে কাজ করবে এবং এটি যদি ওরিওর নীচে থাকে তবে প্যাথটিল কাজ করবে han ধন্যবাদ!
