get_details_permissions() working correctly?

See original GitHub issue

Describe what you wanted to do

I’m getting odd results from calling get_details_permissions() as every permission is marked as unknown and ‘normal’

Describe what you expected

a, dx, d = AnalyzeAPK('package.apk')
a.get_details_permissions()

Given this list of permissions found:

['com.android.launcher.permission.INSTALL_SHORTCUT',
 'android.permission.READ_SETTINGS',
 'android.permission.WRITE_SETTINGS',
 'android.permission.ACCESS_NETWORK_STATE',
 'android.permission.WRITE_EXTERNAL_STORAGE',
 'android.permission.INTERNET',
 'android.permission.READ_PHONE_STATE',
 'android.permission.READ_SMS',
 'android.permission.SEND_SMS',
 'android.permission.RECEIVE_SMS',
 'android.permission.READ_CONTACTS']

I would expect to get appropriate levels, for instance READ_SMS should return dangerous

Describe what actually happened

This is the actual result:

{'android.permission.ACCESS_NETWORK_STATE': ['normal',
  'Unknown permission from android reference',
  'Unknown permission from android reference'],
 'android.permission.INTERNET': ['normal',
  'Unknown permission from android reference',
  'Unknown permission from android reference'],
 'android.permission.READ_CONTACTS': ['normal',
  'Unknown permission from android reference',
  'Unknown permission from android reference'],
 'android.permission.READ_PHONE_STATE': ['normal',
  'Unknown permission from android reference',
  'Unknown permission from android reference'],
 'android.permission.READ_SETTINGS': ['normal',
  'Unknown permission from android reference',
  'Unknown permission from android reference'],
 'android.permission.READ_SMS': ['normal',
  'Unknown permission from android reference',
  'Unknown permission from android reference'],
 'android.permission.RECEIVE_SMS': ['normal',
  'Unknown permission from android reference',
  'Unknown permission from android reference'],
 'android.permission.SEND_SMS': ['normal',
  'Unknown permission from android reference',
  'Unknown permission from android reference'],
 'android.permission.WRITE_EXTERNAL_STORAGE': ['normal',
  'Unknown permission from android reference',
  'Unknown permission from android reference'],
 'android.permission.WRITE_SETTINGS': ['normal',
  'Unknown permission from android reference',
  'Unknown permission from android reference'],
 'com.android.launcher.permission.INSTALL_SHORTCUT': ['normal',
  'Unknown permission from android reference',
  'Unknown permission from android reference']}

Let’s see if we can fix #529 as well.

Yes makes sense, the behavior might be to load the next higher version available or the highest available if the analysed targetSDK is above the highest one available (the 2 apk provided fall one in the first category and the other on the second).

Thanks for your prompt answers
