Please don't mark this as a duplicate,
I am trying to send the id to my online server. In that I have create a db and a table to store the id.
When user first installs the app, the id will send to the server. and it is working fine.
My question: How to check whether the user (id) stored in table has installed my app or the app has been uninstalled from android device.
If user has uninstalled my app, then i want to remove the id from the table.
I am not using any username and password, to verify each user uniquely.
any kind of help is appreciate.
Thanks in advance.
