Currently I am using target 19 (Android 4.4) and i have attached support library v4 in jar. I want to upgrade targetSdk to API 23 to handle Runtime Permissions, hovewer there is no clear explonation in web how to do it, and changing targetSdk in Manifest and gradle isn't enough because classes responsible for runtime permission from API 23 are not found.. could you tell me step by step what should i do ?
And second one : should i use android-support v4 or v7 or other version ? what you would advice ?
