Since I did not change the manifest, it is a riddle why this can be the case. I can decompile it and see if this happened. Meanwhile I have taken an earlier version and made the changes again. It compiles and I can make version copies. I know an ugly solution but it worked.
In my case it happened the Koduloid game, which I started recently. And I never made an app when it was named Makeroid. I made a copy of it and when I tried installing the copy, the installation went OK but I couldn’t find the app anywhere, except in the Apps Settings.
I downloaded the aia, made this change from @7StarMedia and re uploaded it. After that the apk installed perfectly.
It is awful but again the same error is risen. My working aia and apk can be saved as a checkpoint, but the result of the copy will produce a non visible app. Checking manifest.xml the line < category android:name=“android.intent.category.LAUNCHER” /> is missing.
But I just copied a working file without any changes in Kodular. What to do Boban because of this erroneous behavior?
It seems that decompiling apk, adding < category android:name=“android.intent.category.LAUNCHER”/ > and (App2market) compiling it, is the only solution for now. A lot of extra steps, but if there is no other solution, it is.
I wholeheartedly hope, it is the only project that will show this behaviour.
