无法hook只有赋值代码的set、get方法

[weimingjue]

反馈BUG之前，先issue里面搜看看有没有别人已经反馈过，重复的不予处理！！

问题描述

android代码：MainActivity里面

private String mSt;
public void setString(String ss) {
    mSt = ss;
}
protected void initData() {
    setString("哈哈");
    Log.i(TAG, mSt);
}

hook代码：在handleLoadPackage中
XposedHelpers.findAndHookMethod("com.wang.hongbao.MainActivity", lpparam.classLoader,
"setString", String.class, new XC_MethodHook() {
@OverRide
protected void afterHookedMethod(MethodHookParam param) throws Throwable {
super.afterHookedMethod(param);
LogUtil.logXposedI("hokkset方法：" + Arrays.toString(param.args));
}
});
结果：必崩溃，日志如下
