How to read Android Intent.EXTRA_TEXT in unity

Question

How can I read the Intent.EXTRA_TEXT in Unity?

My Android Code is as follows:

intent.PutExtra(Intent.EXTRA_TEXT,"teststring");
startActivity(intent);

My Unity Code is as follows:

string arguments = "";
AndroidJavaClass UnityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
AndroidJavaObject currentActivity = UnityPlayer.GetStatic<AndroidJavaObject>("currentActivity");

AndroidJavaObject intent = currentActivity.Call<AndroidJavaObject>("getIntent");
bool hasExtra = intent.Call<bool>("hasExtra", "arguments");

if (hasExtra) {
    AndroidJavaObject extras = intent.Call<AndroidJavaObject>("getExtras");
    arguments = extras.Call<string>("getString", "arguments");
    Debug.Log("args: " + arguments);
}

And it does not work. Also, I haven't modified the AndroidManifest.xml in Unity. Am I missing something?

I don't know much about accessing Intent data within Unity. I'd really appreciate any help on this.

Thanks.
