Game doesn't start when I build it for android

Hi, I’m trying to build an old project using unity 5.5.1f1 for android, In unity’s editor everything runs perfectly, but when I open the app instaled on my phone it only shows a black screen, it doesn’t even show unity’s splash scene, I have installed the jdk 8 and I don’t know what sdk version should I use, does anyone knows how to solve this problem?

Thanks for your time

Provide the device logs using “adb logcat”

Is this the log you are refering to?

Yes, if these are logs from the device. And I believe you’ll find your answer in the logs! Look for the null reference exception, you’ll want to debug around that code https://discussions.unity.com/t/748729/14
