Camera not rendering UI

I've two cameras, one main camera and other is a rear view camera, I've text mesh pro in canvas set to world space, the text is "Engine ready", this text is displayed in rear view camera but not in main camera on android.

Everything works fine in editor, the problem occurs on android device.


This is the display from android device, no text is displayed.


This is from the editor, this is what android device should display too.


As you can see the rear view camera (at top middle) displays the text too( when players walks past it).

 

why do you not simply render your UI in the "screen space - Overlay" mode?

 

I want the text to be placed in the 3d world so the car can go past it, just to give a good effect.

 

Okay, I got the idea now.
Unfortunately I do not have an idea what could cause it...
Did you check the android logs? (

adb logcat -s Unity

)

 

It's the first time I'm hearing about it, what this do?

 

adb is a tool for reading android logs. It is somewhere at your Android SDK location (I think inside the tools folder).
navigate there with a command line tool (or better add that path to your PATH variables). Then write

adb logcat -s Unity

to get all the logs which a unity app on the android device produces.
Here some more info: https://developer.android.com/studio/command-line/logcat

 

Thanks, I'll use it to find the problem.
