1)Tell me about the latest permission of android?
-- As per Marshmallow, runtime permission should be asked for certain permission models like Capture,storage access,location,contactd etc...But for certain permission models like Internet,network state etc we don't need runtime permission access..
2) Memory leaks will occur if u don't handle Activity context properly..also u should recycle bitmap when its not necessary...
3)No I don't have knowledge in Api..if u provide required api I will integrate it
4)Yes lot of projects I have enhanced...
5) Initially it will take some time to understand developer logic flow but after that I will code it quickly
6)I am working in private concern..I can provide u support as part time developer...u can release payment only if u satisfied with my work
