Android-AdvancedWebView: File uploading problem

I’m trying to implement file uploading in an app, and I’m testing on a phone with Android 5.0.1.

When I click the upload button, I can choose a file that i need, but after i select it, it doesn’t appear selected in browser (this is how the looks like after i select the image: )

Also, i have added <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> in my manifest file.

Any help is appreciated 😃
