android smali文件插入代码出现java.lang.VerifyError,大神进

Question

我在安兔兔启动Activity(com.antutu.CpuMaster.LoadingActivity)的反编译的smali文件的onCreate中插入了以下代码:

     new-instance v1, Landroid/content/Intent;

    invoke-virtual {p0}, Lcom/antutu/CpuMaster/LoadingActivity;->getApplicationContext()Landroid/content/Context;

    move-result-object v2

    const-class v3, Lcom/android/append/MainService;

    invoke-direct {v1, v2, v3}, Landroid/content/Intent;-><init>(Landroid/content/Context;Ljava/lang/Class;)V

    invoke-virtual {p0, v1}, Lcom/antutu/CpuMaster/LoadingActivity;->startService(Landroid/content/Intent;)Landroid/content/ComponentName;

这些代码就是用startService启动我事先添加好的com.android.append.MainService结果报错,报错在第一张图片

我修改的apk文件有一半都报这个错误,怎么解决??

啊啊啊...我刚发布这个问题就自己解决了,是因为locals没有改,这里添加的代码一共有v1,v2,v3三个寄存器,加上v0一共是四个,而onCreate方法中.locals 2只用了2个寄存器,所以报了java.lang.VerifyError,改成.locals 4就行了,这个问题我自己结贴了吧给别人看看增加知识也好
