try to add this line in AndroidManifest.xml

 <application
...
        android:vmSafeMode="true"
...  
      >

[2767321434]

怀疑是这个文件里的VirtualApp\lib\src\main\jni\Foundation\VMPatch.cpp
下面这段代码的问题
void disableJit(int apiLevel) {
#ifdef arm
void libart = fake_dlopen("/system/lib/libart.so", RTLD_NOW);
if (libart) {
// disable profile.
void processProfilingInfo = NULL;
const char processProfileInfoFunc =
apiLevel < 26 ? "_ZN3art12ProfileSaver20ProcessProfilingInfoEPt" :
"_ZN3art12ProfileSaver20ProcessProfilingInfoEbPt";
processProfilingInfo = fake_dlsym(libart, processProfileInfoFunc);
ALOGE("processProfileingInfo: %p", processProfilingInfo);
if (processProfilingInfo) {
MSHookFunction(processProfilingInfo, (void)processNothing, (void)&orig_ProcessProfilingInfo);
}

// disable jit
void *compileMethod = NULL;
compileMethod = fake_dlsym(libart,
                           "_ZN3art3jit3Jit13CompileMethodEPNS_9ArtMethodEPNS_6ThreadEb");
ALOGE("compileMethod: %p", compileMethod);
if (compileMethod) {
    MSHookFunction(compileMethod, (void*) compileNothing, (void**) &orig_CompileNothing);
}

}

Try add the code:

try {
    Class<?> klazz = Class.forName("dalvik.system.VMRuntime");
    Object vmRuntime = klazz.getMethod("getRuntime").invoke(null);
    klazz.getMethod("disableJitCompilation").invoke(vmRuntime);
} catch(Exception e) {
    e.printStackTrace();
}

[weimingjue]

    android:vmSafeMode="true"

成功解决，十分感谢

[tianxiayu007]

@weimingjue
这么easy就解决问题了吗大佬?? 能不能贴一下编译后的apk...

[weimingjue]

尝试在AndroidManifest.xml中添加此行

 <application
...
        android:vmSafeMode="true"
...  
      >

尝试添加代码：

尝试 {
     Class <？> klazz =  Class 。forName（“ dalvik.system.VMRuntime ”）;
    对象 vmRuntime = klazz 。getMethod（“ getRuntime ”）。invoke（null）; 
    克拉兹。getMethod（“ disableJitCompilation ”）。调用（vmRuntime）; 
} catch（例外 e）{ 
    e 。的printStackTrace（）; 
}

虽然解决了但又有新的问题了：里面的xposed模块不能用了，xposed install打不开无限加载中。。。

[weimingjue]

@lubocheng 我的只是9.0系统这样，其他手机都正常，你先试试你的在7.0之类的能不能用吧

[canyie]

@weimingjue 试下太极能用吗？

[tramix32]

@weimingjue @canyie can u upload app with with fixed problem?

[weimingjue]

@weimingjue @canyie can u upload app with with fixed problem?

是“xposed install”不能使用了，不是某个app。日志没发现什么有用的信息。

[canyie]

@tramix32 My equipment does not have this problem.

[weimingjue]

@lubocheng 我的是红米note7pro android系统9.0，xposed模块不能使用实在解决不了了，整个github都搜了一下找到了个差不多的叫“SandVXposed”大家可以试试。不是有意侵犯作者，只是让大家多参考参考

[tramix32]

We are waiting so long to fix.. Btw sorry I don't understand Chinese and translator can't help a lot 😄

[canyie]

@tramix32 The problem does not seem to have been solved. You can try using SandVXposed or TaiChi.

[tramix32]

@canyie i need exactly vxp to install another snapchat and snaptools :D without repacking snapchat like taichi do. And i tested svxp but its not working properly for me :/

[canyie]

@tramix32 Perhaps you could issue an issue to the SVXP author?

[tianxiayu007]

老大佬，既然fix了..就发个新版呗...

[tianxiayu007]

大佬，既然fix了，就发个新版呗~~~
