Question

i have calling java function from my unity code.
I have both static & non-static type of functions in my java class
To access first static function, i used:

AndroidJavaClass plugin = new AndroidJavaClass("com.android.test.TestActivity");
AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject activity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");        
plugin.CallStatic("InstantiateMe", qwe);

above code is running fine, but after this , when i m trying to execute my non static function, its not actually executing.. Not even giving any exception or error..

My code to call non-static function

AndroidJavaClass plugin = new AndroidJavaClass("com.android.test.TestActivity");
AndroidJavaClass unityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject activity = unityPlayer.GetStatic<AndroidJavaObject>("currentActivity");        
plugin.Call("Enable", qwe);

Help me guyz. i stucked here.

Answer 1

use your “activity” variable for non-static calls: activity.Call("Enable", qwe);
There is example of static and non-static functions calls:

public class Caller {
  private readonly AndroidJavaClass _ActivityClass;
  private readonly AndroidJavaObject _ActivityObject;
  private readonly AndroidJavaClass _MyActivityClass; 

  public Caller() {
    _ActivityClass = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    _MyActivityClass = new AndroidJavaClass("com.example.u2aTest.MyMainActivity"); 

    _ActivityObject = _ActivityClass.GetStatic("currentActivity");
    // AndroidJavaObject my_activity_object = _MyActivityClass.GetStatic("currentActivity"); //doesn't work
  }

  public void MakeTestCalls() {
    _ActivityObject.Call("testVoid"); // works fine
    //_ActivityClass.CallStatic("testVoidStatic"); // doesn't works
   _MyActivityClass.CallStatic("testVoidStatic"); // works fine
    //_ActivityObject.CallStatic("testVoid"); // doesn't work on some divices

   //public int testInt(int intValue)
   int iresult = _ActivityObject.Call<int>("testInt", 999);

   //public String testStringString(String paramValue)
   String sresult = _ActivityObject.Call<String>("testStringString", "s2");      

   //public static int testIntStatic(int intValue) 
   iresult = _MyActivityClass.CallStatic<int>("testIntStatic", 999);

   //public static String testStringStringStatic(String paramValue)
   sresult =_MyActivityClass.CallStatic<String>("testStringStringStatic", "s1");
  }
}

Take a look on example of Android plugin for Unity3D for detailes.
