This is a jscheme interpreter and a java compiler for android. It has the ability to interpret and compile java code to class -> dex/jar using ecj compiler and dx - the java compilance level however is at 1.5 (problems to have java 8 or 9 compilation directly on the android platform are well known). Although a newer version of the app with an intergrated javac 11.0.16 compiler is available.
ecj.jar and dx.jar for compilations are included. A newer version include a newer javac 11.0.16 compiler instead of ecj. An external editor app should be installed. I use com.aor.droidedit.pro, if you like to use another editor simply replace your package new in here: Scheme.context.getPackageManager().getLaunchIntentForPackage("com.aor.droidedit.pro");
To install, create an apk (either from command line, for example see build-instructions.sh, or using the studio). After installing the apk, create a folder on your phone: /sdcard/Download/java and within three subfolders code, compile and libs (this is for the apps you will create) You will need a android.jar used for compilation, put it in and as: /sdcard/Download/java/android.jar
Several examples to make android applications to be added soon. This below shows how to compile a java program and load it to use.
