Hello everyone,
I have copied a project, then i changed the keystore, package, company, product name. however, when i build an APK i can’t install the APK unless I delete the APK of the other project that got copied. I can’t install the two APK’s side by side i don’t know why. Is it something to do with AndroidManifest somehow ?

ok I solved the problem. It turns out the
android:authorities=
at AndroidManifest was the same in both builds which caused conflicts.
