Hi,
did you remember to comment out the line in the interpreter.cpp file in order to allow the player integrated in the app, to use the bytecode.byc that you compiled (and put in assets directory)? In the manual it is explained clearly.
In latest AppGameKit distribution,line 249 of interpreter.cpp:
#ifdef IDE_ANDROID
// Assign byte code filename when running standalone
strcpy ( g_pInterpreterByteCodeFile, "bytecode.byc" ); // comment in for T1 BASIC APP
#endif
About the second question, the apk is ready to be submitted to Google but...
- you need the Developer account (25$).
- you have to feed images and description about your app.
- if you want to sell your app, you also need to set up payment detail.
