只能说，有了xposed以后，对于java代码的hook从此非常简单
直接粘贴代码了，对于xposed 怎么上手，请参考https://github.com/rovo89/XposedBridge/wiki/Development-tutorial
关键是找到addJavascriptInterface这个函数并hook即可，然后找到到底注入的名字以及object对象。
public class Tutorial implements IXposedHookLoadPackage {
???? public void handleLoadPackage(final LoadPackageParam lpparam) throws Throwable {
???? //XposedBridge.log("Loaded app: " + lpparam.packageName);
???????? if (!lpparam.packageName.equals("com.ali.tg.testapp"))
???? return;
????findAndHookMethod("android.webkit.WebView",lpparam.classLoader,"addJavascriptInterface",Object.class,String.class,new XC_MethodHook(){
????@Override
protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
// this will be called before the clock was updated by the original method
????XposedBridge.log("before addJavascriptInterface:"+param.args[1].toString());
????XposedBridge.log("methods:");
????Object obj=param.args[0];
????Class<?> cls= obj.getClass();
????Method[] ms=cls.getDeclaredMethods();
????for( int i=0;i<ms.length;i++)
????{
????????XposedBridge.log(ms[i].toString());
????}
}
@Override
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
?
}
});

???? }
}
