我想将Unity中的数据发送到java for android插件。
这是我的Unity代码:
AndroidJNI.AttachCurrentThread();
IntPtr cls_Activity = AndroidJNI.FindClass("com/unity3d/player/UnityPlayer");
IntPtr fid_Activity = AndroidJNI.GetStaticFieldID(cls_Activity, "currentActivity", "Landroid/app/Activity;");
IntPtr obj_Activity = AndroidJNI.GetStaticObjectField(cls_Activity, fid_Activity);
Debug.Log("Setup Objects Complete");
IntPtr cls_OurAppNameActivityClass = AndroidJNI.FindClass("org/plugin/test/AdmobTestActivity");
IntPtr startAdsMethod = AndroidJNI.GetMethodID(cls_OurAppNameActivityClass, "EnableAds", "(J)V");
Debug.Log("before If Loop");
if (AndroidJNI.IsInstanceOf(obj_Activity, cls_OurAppNameActivityClass) != false)
{
//Debug.Log("Activity IS a OurAppNameActivity");
jvalue[] myArray = new jvalue[1];
myArray[0] = new jvalue();
myArray[0].i = 12;
AndroidJNI.CallVoidMethod(obj_Activity, startAdsMethod, myArray);
Debug.Log("Activity Leaving a OurAppNameActivity");
}
这是我的Java代码:
public void EnableAds(int qwe)
{
Log.i(APP_TAG, "Value" + qwe);
}
错误:
05-16 13:11:30.906: W/dalvikvm(12315): threadid=8: thread exiting with uncaught exception (group=0x40018578)

AND FORCE CLOSE ..
如果我在java代码中从EnableAdv(int qwe)中删除了int参数,那么这个应用程序工作正常。
任何人都可以告诉我,我在这段代码中遗漏了什么。?
答案 0 :(得分:1)
我找到了答案..
我想用“(J)V”作为我的论据类型......但是我不喜欢使用“(I)V”。
例如,Java方法:
long f(int n,String s,int [] arr); 具有以下类型签名:
“(ILjava /郎/字符串; [I)V
