List of all actions protected by given permission

Question

I am supposed to perform static analysis of an APK that has a lot of permissions requested in the Manifest.

I would like to find out whether all the permissions requested are really needed by the app to perform some action.

When I read documentation for a specific permission, it hardly mentions what actions (API calls, object initiations, broadcasts etc.) are specifically protected by that permission.

For example: When I read the docs of READ_PHONE_STATE here, it never mentions the actual API calls protected by the permission. I need to google and find that the user needs this permission to call some methods of TelephonyManager, which is something that I can try to find in the Smali code of my APK to verify that the permission is really needed.

So my question is: Is there some documentation, website or list, where I could easily find all assets protected by various Android permissions? The documentation usually contains all permission needed by a specific call, but it does not contain all calls protected by a specific permission.
