Method hangs on Android, but works in editor

The menu part of my app works fine in the editor. It activates and deactivates various canvas game objects based on user selections. BUT... when I build and run this app on my Samsung Android phone and select "Game Menu" on the main menu, it would stall, not do any of the statements in the GoToGameMenu method.

To help debug the app, I linked the Game Manager method to a little SoundFX class with a PlayBeep method. What's so crazy is that wherever I put the PlayBeep call in the GoToGameMenu method, when I ran the app on my Android phone, it would run the statements up to and including the beep, and then stall. When I finally put the playBeep call at the end of the method, it would run every statement in the method correctly. But if I remove the playBeep call from the method, it returns to not running any statements from this method. Does anyone have any ideas on why this method only works on Android when an external method call like this is included and only up to and including it, and nothing past it? I'm really hoping to avoid having to put the workaround all throughout my code just to make methods work. Thanks!

Here's the stalling method that's contained in my Game Manager monobehaviour class. In this version, it actually runs every statement ONLY because the playBeep is included at the end:

#region GoToGameMenu
public void GoToGameMenu()
{

currentMenu = "game";

mainMenu.SetActive(false);

//Game Menu setup
genMenuGameObject.SetActive (true);

genMenu.title.text = "Game Menu";
genMenu.prompt.gameObject.SetActive (false);
genMenu.option1.gameObject.SetActive (true);

if (PlayerPrefs.HasKey ("game")) {
LoadGameData();
genMenu.option1Text.text = "Continue Game";
genMenu.option3.gameObject.SetActive(true);
genMenu.option3Text.text = "End Game";
} else {
genMenu.option1Text.text = "New Game";
genMenu.option3.gameObject.SetActive(false);
}

genMenu.option2.gameObject.SetActive(false);
genMenu.option4.gameObject.SetActive(false);
genMenu.okButton.gameObject.SetActive (false);
genMenu.backButton.gameObject.SetActive (true);
genMenu.backText.text = "back";

// BEEP SOUND
SoundFX.PlayBeep ();

}
#endregion




Separate class containing the playBeep method:

public class SoundFX: MonoBehaviour {

public AudioClip beepSound;
private AudioSource audioSource;

void Awake () {
audioSource = GetComponent<AudioSource>();
}

public void PlayBeep () {
audioSource.PlayOneShot (beepSound, 0.5f);
}

}


Unity 5.2.2, Samsung Galaxy J3 running Android 6.0.1

 

FIXED: android was hanging because my internal debug method was trying to write to a debug.txt file. writing to that file works on my PC, but Android couldn't find the path and was crashing.

Found this looking at logcat, so thanks JeffUnity3D for the suggestion.
