Get all non media files in Android 2.3

Question

How to get all non media files in android 2.3 ?

    ContentResolver cr = getApplicationContext().getContentResolver();
    Uri uri = MediaStore.Files.getContentUri("external");

    String selection = MediaStore.Files.FileColumns.MEDIA_TYPE + " = " + MediaStore.Files.FileColumns.MEDIA_TYPE_NONE;

    imagecursor = cr.query(uri, null, selection, null, null);

    while (imagecursor.moveToNext()) {
        count++;
    }

From the above i am getting all non media files in Android 4.0 and above. But G etContentUri(external) is not working in Android 2.3, its showing that its added in API level 11. Is there any alternative to get all non media files in Android 2.3 ?

Answer 1

As you said, MediaStore.Files is only available for API 11+. So there isn't any method to use MediaStore to do this. But you have two options to get the non-media files from a device's storage(s).

1. Iterating through all of the files in the storage: In my opinion this is not recommended at all. Because it takes about 15-30 seconds to iterate through all the files. But if you want to do this check here . Then you provide a simple condition to see if it is a non-media file.

2. Listing all the files once in a database and then get them: This is better than first method. For using it you can check this open-source application that exactly does that.
