impossble frida script inject

[luckyguy89]

After I did dump a package using frida-dexdump command and find new classes, I hooked new classes, but Frida said like "trace class failed Error: java.lang.ClassNotFoundException: Didn't find class "com.priguard.C4510KernelInstance" on path: DexPathList[[zip file "/data/app/com.ui-1/base.apk"],nativeLibraryDirectories=[/data/app/com.ui-1/lib/x86, /data/app/com.ui-1/base.apk!/lib/x86, /system/lib, /vendor/lib]]"

Hook code is:
Java.perform(function (targetClass) {
var hook;
try {
hook = Java.use(targetClass);
} catch (e) {
console.error("trace class failed", e);
return;
}
}

Could anyone help me how to hook to com.priguard.C4510KernelInstance?
