Android Studio Permission Denial

I am not sure if this is the right place to ask this question but I can't find help anywhere. I'm trying to get this application to work but I've run into some errors.

Clicking "Open gallery" button immediately crashes whole app with this error:

    FATAL EXCEPTION: main

I don't know why it is happening, I checked the manifest and it seems the required permissions are there.

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" />
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />

I'm using Android Studio 2.3.3 + Nexus 4 API 25 emulator.

As cjnash said, you need to ask for runtime permissions as well. If you need a quick way just to try it, you can go in your device settings and manually give your app the permissions it needs to run.

Although you have included permissions in your manifest, you also need to request runtime permissions as well. Everything you need to know is here:
