安卓9.0下 找不到backup

大佬您好，我最近在做yahfa的接入。其他低版本的安卓系统都运行很完美，但是在安卓9.0的设备上，很大概率会出现backup方法找不到。测试了同一台设备也是安卓8.1正常，升级到9.0上就找不到方法。 例如我hook WindowManagerImpl 的 addView 函数，有些包能正常使用，大多数包会报错。以下是我的代码和具体的报错内容。希望能解决安卓9.0上的这个问题。 public class HookViewDemo { public static String className = "android.view.WindowManagerImpl"; public static String methodName = "addView"; public static String methodSig = "(Landroid/view/View;Landroid/view/ViewGroup$LayoutParams;)V"; public static void hook(Object obj,Object param1,Object param2) { Log.d("TIPS","addview in"); backup(obj,param1,param2); Log.d("TIPS","addview out"); return; } public static void backup(Object obj,Object param1,Object param2) { try { Log.w("TIPS", "load should not be here"); } catch (Exception e){ e.printStackTrace(); } return; } }
