native方法调用返回值是int，调用后如何拿到返回值呢？

[oceanzhang01]

Number ret = TTEncryptUtils.callStaticJniMethod(emulator, "init(Landroid/content/Context;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;Ljava/lang/String;II)I"
, vm.addLocalObject(context),
vm.addLocalObject(new StringObject(vm, "1.1")),
vm.addLocalObject(new StringObject(vm, "")),
vm.addLocalObject(new StringObject(vm, "")),
vm.addLocalObject(new StringObject(vm, "")),
vm.addLocalObject(new StringObject(vm, "./")),
vm.addLocalObject(new StringObject(vm, "./")),
0, 2
);

如上，init 方法调用返回值是int类型，我这边调用后如何拿到返回值呢？

补充一下，好像是vm.getObject(hash).getValue()返回null应该是调用失败了
