TODOs:

• Add GIFs & docs
• SQLite hook example (+Native)

Interceptor.attach(Module.findExportByName('libsqlite.so', 'sqlite3_prepare16_v2'), { onEnter: function(args) { console.log('DB: ' + Memory.readUtf16String(args[0]) + '\tSQL: ' + Memory.readUtf16String(args[1])); } });

• Hook example: java.lang.reflect.Method#invoke(Object obj, Object... args, boolean bool)

    Java.use('java.lang.reflect.Method').invoke.overload('java.lang.Object', '[Ljava.lang.Object;', 'boolean').implementation = function(a,b,c) {
        console.log('hooked!', a, b, c);
        return this.invoke(a,b,c);
    };
  

• Hook constructor

    Java.use('java.lang.StringBuilder').$init.overload('java.lang.String').implementation = function(stringArgument) {
        console.log("c'tor");
        return this(stringArgument);
    };
