Accessing the Activity Context in Android plugin
Is there a way to access the Activity or Application Context for plugin development?
Say I have a method like this:
public static void myMethod(Context context, String s1, String s2)
How would I call this method from Unity?
Right now I'm trying something like this. The problem is obj_Activity is an Activity type ? How would I pass in the App or Activity Context in this case?
// first we try to find our main activity.. IntPtr cls_Activity = JNI.FindClass("com/unity3d/player/UnityPlayer"); int fid_Activity = JNI.GetStaticFieldID(cls_Activity, "currentActivity", "Landroid/app/Activity;"); obj_Activity = JNI.GetStaticObjectField(cls_Activity, fid_Activity); Debug.Log("obj_Activity = " + obj_Activity);
AndroidJavaClass myClass = new AndroidJavaClass("com.test.myClass");
myClass.CallStatic("myMethod",
obj_Activity,
new AndroidJavaObject("java.lang.String", "string1"),
new AndroidJavaObject("java.lang.String", "string2"));
Hm I think I figured it out:
AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");

It helps to add a 'setContext' method to your plugin. You can then pass the context data to the plugin after you acquire it using the code you wrote.
I painstakingly managed to write and use a plugin to detect hardware buttons on an Android device. At first I was a bit baffled as to how to retrieve the actual context in use but your snippet helped to demystify that one.
