Open file from documents on Android Nougat

Question

I'm using file helper class from this post https://stackoverflow.com/a/20559175/2281821 but it doesn't working properly in each case. I'm using Intent chooseIntent = new Intent(Intent.ACTION_OPEN_DOCUMENT); to start file picker. I have Android Nougat and I'm receiving from onActivityResult uri: content://com.android.externalstorage.documents/document/home%3Aimage.png What does this home: means? How can I get access to this file? I was trying with Environment.getExternalStorageDirectory() and System.getenv("EXTERNAL_STORAGE") but I can't get acess.

Are u getting any error or exception than plz paste it here also — Ravindra Kushwaha, Apr 03 '17 at 06:07
There is no error, the path is just incorrect and when I try to create bitmap, it is null — falsetto, Apr 03 '17 at 06:56

Following code can be used to get document path:

Intent galleryIntent = new Intent();
        galleryIntent .setType("image/*");
        galleryIntent .setAction(Intent.ACTION_GET_CONTENT);
        startActivityForResult(Intent.createChooser(galleryIntent , getString(R.string.app_name)),REQUEST_CODE);

OnActivityResult():

@Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {

        if (resultCode == RESULT_OK) {
            if (requestCode == REQUEST_CODE) {
                Uri uri  = data.getData();
            } 
        }

    }

You can use "uri" variable value to get bitmap. If you want to open document other image also then remove following line:

galleryIntent .setType("image/*");

You get access to a content scheme by opening for instance an InputStream on the uri.

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

BitmapFactory.decodeFromStream(is) will happily read from your stream.
