I use AndroidJavaClass and AndroidJavaObject.

But my device return error.

02-26 17:56:34.391: E/Unity(9169): ! getMethodID("initPlasma", "(Ljava/lang/String;)V") FAILED!
02-26 17:56:34.391: E/Unity(9169): JNI: Unable to find method id for 'initPlasma'

//used Unity 4.x code

try
        {
			using (AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
            {
                using (AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity"))
                {
                    jo.Call(JavaMethods.initPlasma, "unity to android");

                }
            }

        }
        catch (Exception e)
        {
			
			Debug.Log(e.StackTrace);
			
        }

export Eclipse project used Unity 4.x.

and I fixed extends UnityPlayerActivity.
ex) class mainActivity extends UnityPlayerActivity

and Added code.

	public void initPlasma(final String unityMessage)
	{
		
		runOnUiThread(new Runnable() {
			public void run() 
			{
            	UnityPlayer.UnitySendMessage("targetUnityObj", "OnInitCompleate", unityMessage + " and android to unity");
            }
		});
	}

How can I edit it?

Many tutorial say change Activity → UnityPlayerActivity.

But, my case still use Activity.

public class myAppActivity extends Activity

and myAppProxyActivity onCreate method, supportsNative value set false.

boolean supportsNative = Build.VERSION.SDK_INT >= 9 /*Build.VERSION_CODES.GINGERBREAD*/;
			supportsNative = false;
