File list is not displayed on Android 6.0 and targetSdkVersion < 23

hi,
I'm using your library within an application that runs on Android 6.0 but has an older targetSdkVersion=21. When I send the intent to open FilePickerActivity it is displayed empty with no files or folders in the list.
Some debugging showed that FilePickerActivity.init() method is not being called on my device. Looks like this method is responsible for setting this.curDirectory to list files from.
After some googling I found the root cause of the issue here:

If the device is running Android 5.1 (API level 22) or lower, or the app's targetSdkVersion is 22 or lower, the system asks the user to grant the permissions at install time.

Hmm this is an interesting issue. Since your target sdk version is less than 23 the app should be requesting the permissions at install time as you said. That means the permissions should be in the manifest. Are the WRITE_EXTERNAL_STORAGE and READ_EXTERNAL_STORAGE permissions in your app manifest?

I'll definitely have to look into this more.

yep. I have both permissions in my manifest.

This simple fix worked for me: #34

I just merged it and will make a new release. Thanks for this!
