它在onCreate的時候 調用里 一個native靜態(tài)方法，用于校驗包的SHA值，

public class App extends MultiDexApplication {

@override

public void onCreate(){

super.onCreate();

....

sign.check(this);

}

}

看smali 和ida 的偽代碼，它傳入了一個Context 到 native 方法 然后嘗試調用 PackageManager 時 傳入的 Context 是NULL導致的？

希望大神幫忙。

v4 = ((int (__fastcall *)(JNIEnv *))(*a1)->GetObjectClass)(a1);

v5 = v4;

v6 = ((int (__fastcall *)(JNIEnv *, int, const char *, const char *))(*v2)->GetMethodID)(

v2,

v4,

"getPackageManager",

"()Landroid/content/pm/PackageManager;");

v7 = _JNIEnv::CallObjectMethod(v2, v3, v6);
