    Few time ago, I download B4A (version trial version), I have reading the 'PDFs', and now it's my time to learn by practicing with it...

    I have loaded a simple example (of which you can download to learn, from source examples compannion B4A), and I have the next error, when i've try compile it:
    "Error java.lang.UnsupportedClassVersionError: com/android/dx/command/Main : Unsupported major.minor version 52.0", etc.etc...

    I finded and read about the problem. The solution (more visible) it's, what I need to install Java 8.0, but it's don't possible in my computer (it's older and Java 8 don't may, dont' want, to install it, ...I have Win-XP sp3... yes too :D, along 1-2 years more :().

    Then my question it's: There are any mode for instruct at the program so that, I want compile with Java 7xxx?.
    En B4A, in Gradle, in Android... in a simple bat :) ?.

    There are options for to tell to B4A, what I want to compile it with a specific (Java) version????.

    You can install Java 8 on Windows XP.
    Though you will encounter other issues as well. Android SDK is not fully supported on Windows XP.
