Several day ago, I set up the private sign key for study the firebase.
After that time, I cannot run a new file(program). It will have an error occurred while compiling.
The error is as follow

I'm guessing you are not changing the package name when you create a new project. Either change the package name (CTRL-B & then change b4a.example to something else) or try uninstalling the B4A Example app from the device & then compile the new one. You should only have to do that once.

Yes - it fails while compiling at the point where it is trying to install on the device. Check on your device & if you have an app called B4A Example, uninstall it.

Correction - the app you need to uninstall on your device is called "testread.apk".

Dear Colin
I found that the error only occur when I install it on emulator. If I install the apk in my Asus phone, It runs OK.
Usually I test programs on the emulator. So I didn't install testread.apk in my phone before.
How do I do so that I can also install on emulator

You need to uninstall it from the emulator.

The error you posted happens when there is an existing installed app with the same package name and targetSdKVersion >= 23. You are trying to install an app with targetSdkVersion = 19. It fails because the previous app uses the new runtime permissions system and the new one doesn't.
