Question

I have this app installed in my device (Nexus s).
It caches some images if you use this app. This is why it shows cached images in my device’s gallery.

I use cursor to get the path

final String[] columns = { MediaStore.Images.Media.DATA };
Cursor imagecursor = managedQuery(
        MediaStore.Images.Media.EXTERNAL_CONTENT_URI, columns,
        MediaStore.Images.Media._ID + " = " + id, null, MediaStore.Images.Media._ID);
if (imagecursor != null && imagecursor.getCount() > 0){
    imagecursor.moveToPosition(0);
    String path = imagecursor.getString(imagecursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA));
    Log.d("path", path);
    File f = new File("file://" + path);
    Log.d("check_file", "" + f.exists());
}

I get the path:

/mnt/sdcard/cache/hk.ignition.podcast/cartoon/2/http%3A%2F%2Fbigcity.learnenglishapps.com%2Fimages%2Fcartoons%2Fset2%2Ffast-food-new-1.png

Downloaded image is:
http://bigcity.learnenglishapps.com/images/cartoons/set2/fast-food-new-1.png

When I pull the file or explore it with file manager like Astro, its there.
But when I check if file exist, then it says false.

Is there any character issue?

Update:

Removing file:// worked to check if file exist.

Next is, I’d like to open that file in gallery.

1. should I use this path to open image?
   But that not worked:

    Intent intent = new Intent();
    intent.setAction(Intent.ACTION_VIEW);
    intent.setDataAndType(
                Uri.parse("file:///mnt/sdcard/cache/hk.ignition.podcast/cartoon/2/http%3A%2F%2Fbigcity.learnenglishapps.com%2Fimages%2Fcartoons%2Fset2%2Ffast-food-new-1.png"),
                "image/*");
    startActivityForResult(intent, 3);

1. Or I should try to get content:// style path from MediaStore?

Update 2:

Solved using :

Uri.fromFile(f);

Instead of Uri.Parse(). As it builds / character from encode format.

Answer 1

Change new File("file://" + path) to just new File(path)
