I need to unzip files from the OBB extension after Android installs the APK. After the APK install, I have to manually check in my app if there is enough space to unzip the OBB file.
I am just wondering if there is any way to not allow Android proceed with APK installation if user does not have a certain required storage space that I specify.
No, this is not possible. But even if it was, there wouldn't be way of preventing the user of using more space between install and first run of your app.
