无法hook只有赋值代码的set、get方法 #443
Description
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
