Unity call android static function of java class

Question

Hi i'd like to call this piece of android java code in unity with c# here the java code:

SmsDialog.getInstance().init(this);
//this is context of android activity

And right now i'm doing it like this in my c# code:

void ShowPaymentDialog()
{

    AndroidJavaClass smsDialog = new AndroidJavaClass("com.mobagym.testsdkmobagym.SmsDialog");
    smsDialog.CallStatic<AndroidJavaObject>("getInstance").Call("init",getContext());
}
AndroidJavaObject getContext()
{
    AndroidJavaClass jc = new AndroidJavaClass("com.unity3d.player.UnityPlayer");
    AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject>("currentActivity");
    return jo;
}

There are no crashes or anything, Just that game stops and doesnt execute lines after ShowPaymentDialog.

void Start () 
{
    ShowPaymentDialog();
    GoogleAnalyticsV4.getInstance().LogScreen(MyMenuManager.SPLASH_SCREEN);
    StartCoroutine(Next());
}
IEnumerator Next()
{
    yield return new WaitForSeconds(duration);
    SceneManager.LoadScene(MyMenuManager.MAIN_MENU);
}

so i'd like to know if i'm doing sth wrong with c# syntax. And if there are any ways to log this.

Answer 1

You should try to log the error as you mention. Try setting up a try catch block.

Try {
    //do some logic
} catch (Exception e){
    //Log exception
}

Check this link: https://docs.unity3d.com/ScriptReference/Debug.LogException.html

Maybe when you have stacktrace with exact error we can provide more assistance.

Answer 2

You are probably having a native java exception and missing it. You should connect a device to it and monitor the device log with adb logcat looking for your method call. This should give you enough information to continue debugging.
