Fix android application and php code to get correctly reward

Hello, So, our application giving reward for downloading anothers aps. URL [login to view URL] Inside application we have menu - "Breakfest" and "nice cake". They almost is same, just first is just install, second is user must search app by keyword. This activities in application call [login to view URL] and [login to view URL] So, we here "public void onAppInstall24Hr" they checking or app is installed, for how much time is installed. And [login to view URL](getApplicationContext - showing when user will be awarded. It have a bit buggy, we need fix it, to show for users nice, when he can get reward. So, from this page - [login to view URL] and [login to view URL] we have collum hours. This is time, how much time app must be installed in the phone, and when we will give reward. So, sometimes users don't getting reward, but they sending images for me with icons, so aps is already installed. But they still getting reward. When i am testing on own devices everything is working nice. One bug is that user installing couple aps once and when he getting back to aps with many aps installed. It can be, but we have and different developers name, so i dont think it happens always. So, hope you understand everything. Please fill correct wanted payment it's 30 USD and please write saparas job if you read till end. I think we need add to mysql users when they must be rewarded. And just when user opens application we will check or user ID is in database and if apps still is installed if not installed we will remove from waiting list and add toast message, You have deleted "application name".
