Convert file: Uri to File in Android

What you want is...

new File(uri.getPath());

... and not...

new File(uri.toString());

Note: uri.toString() returns a String in the format: "file:///mnt/sdcard/myPicture.jpg", whereas uri.getPath() returns a String in the format: "/mnt/sdcard/myPicture.jpg".

use

InputStream inputStream = getContentResolver().openInputStream(uri);    

directly and copy the file. Also see:

https://developer.android.com/guide/topics/providers/document-provider.html

After searching for a long time this is what worked for me:

File file = new File(getPath(uri));


public String getPath(Uri uri) 
    {
        String[] projection = { MediaStore.Images.Media.DATA };
        Cursor cursor = getContentResolver().query(uri, projection, null, null, null);
        if (cursor == null) return null;
        int column_index =             cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        String s=cursor.getString(column_index);
        cursor.close();
        return s;
    }

Android + Kotlin

1. Add dependency for Kotlin Android extensions:

   implementation 'androidx.core:core-ktx:{latestVersion}'

2. Get file from uri:

   uri.toFile()

Android + Java

Just move to top ;)
