I have created a simple relay on/off app using google firebase. When I installed it successfully gets installed in mobile phone but when I launch it crashes & closes immediately without any error.
I have a similar app using firebase with 4 relays on/off developed by another person. When I use his .aia file to download .apk from the app inventor site, it does not crash in the phone after launch but when I just change firebaseDB token & URL in his .aia file and then install in the phone, then it crashes immediately without any error.
What could be the possible remedy for this problem?
