我有一个问题。 我试图将一些代码注入特定的代码点。 在几乎一点上，代码注入成功。
但＆＃39; com / google / ads / e＆＃39; 包中的＆＃39; 方法代码注入失败。 代码点位于＆＃39;：goto_2＆＃39; 和＆＃39;返回v0＆＃39; 。
此时，某些代码如＆＃39; const / 4 v1,0x1＆＃39; 都可以 但是，其他代码，如＆＃39; const-string v1，＆＃34; aaa＆＃34;＆＃39;，＆＃39; new-instance v1，〜＆＃39;，＆＃39; sget当应用程序运行时，v1，〜＆＃39; 会崩溃，但v1不会影响效果。
这个问题似乎与监控指令有关。但我不知道为什么会出现这个问题。
