using JNI AndroidJNI.GetMethodID in unity with string parameters

Question

I'm working on unity with android java plugin I was trying to call function from java in unity and it worked successfully.

        cls_Activity = AndroidJNI.FindClass("com/unity3d/player/UnityPlayer");
        fid_Activity = AndroidJNI.GetStaticFieldID(cls_Activity, "currentActivity", "Landroid/app/Activity;");

        obj_Activity = AndroidJNI.GetStaticObjectField(cls_Activity, fid_Activity);
        kdataActivityClass = AndroidJNI.FindClass("com/kdata/unitytest/UnityUrlPlugin");
startAdsMethod = AndroidJNI.GetMethodID(kdataActivityClass,"getURL","(I)Ljava/lang/String;");

        jvalue[] myArray = new jvalue[1];
        myArray[0].i =testvalue;
        gui.text=   AndroidJNI.CallStaticStringMethod(obj_Activity, startAdsMethod, myArray);

Using above code, I was enable to pass int value to my java function and recieve string value . When I'm trying to pass a string value, it's not working for me. The problem is somewhere here because there is no string type in JNI

jvalue[] myArray = new jvalue[1];
myArray[0].i =testvalue;

have you tried jstring? Your question isnt very clear, and there are parts of your code missing — bobby, Jun 07 '12 at 05:10
i solved it brother and this is what i wanted myArray[0].l = AndroidJNI.NewStringUTF(credentials); — Shoaib Ahmed, Jun 07 '12 at 06:05

The data type you are looking for is jstring and in JNI you can create it using newString or newStringUTF

The problem is that he's using Unity, and for some reason they expose jvalue but not jstring. – GrandOpener May 11 '14 at 00:02
