java - Replace SDK classes with classes from JAR in my app -


i need use json.org jar file libs folder in project instead of android sdk json.org classes.

i have set eclipse , prefer json.org classes jar instead of android sdk. when run app on device use sdk json.org classes.

i think, can load json.org classes jar manually using custom class loader.

it possible do? or may exists other way use classes lib instead of sdk classes?

  1. if want use specific jar instead of existing in android sdk, can set priorities in eclipse (right click -> build path) , specify priority.
  2. if want load jar in class loader, it's possible, can use class url

urlclassloader jsonurl = new urlclassloader (jsonjar.tourl(), this.getclass().getclassloader()); class classtoload = class.forname ("com.myclass", true, jsonurl); method method = classtoload.getdeclaredmethod ("mymethod"); object instance = classtoload.newinstance (); object result = method.invoke (instance);
