Thanks for the quick reply npsonic,
I have to try different font sizes in different screen resolutions and I assumed that I could with the emulator.
I will create a smaller app with the minimum of libraries to do the tests.
Only one question, from Tools / Run AVD Manager does not open the administrator of AVD, but the B4A AVDManager.
And from the B4A AVDManager I do not know how to create new virtual devices outside Platform 24.

I have AVD Manager installed but I do not know how to open it from the command line.
Is it possible to open it? How can the AVD Manager be executed from the command line?
I do not mean the emulator: D: \ 0000AndroidEstudio \ Componentes \ emulator \ emulator.exe -avd Note3_API_27
I mean the avdmanager: D: \ 0000AndroidEstudio \ Components \ tools \ bin \ avdmanager.bat
Attached other image.
