[xmlvm-users] crash on iphone simulator running my ported application

[Joseph R. F. <ruk...@op...>]

Hi,

I was trying to play with xmlvm and see it working porting an android  
app to iphone.

I wrote this simple android app which runs ok in the android emulator.

package com.home.imageviewer;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.ViewGroup.LayoutParams;
import android.widget.AbsoluteLayout;
import android.widget.ImageView;
import android.widget.LinearLayout;

public class ImageViewer extends Activity {
     /** Called when the activity is first created. */
     @SuppressWarnings("deprecation")
	@Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);

         AbsoluteLayout layout = new AbsoluteLayout(this);
         layout.setLayoutParams(new LayoutParams 
(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT));
         ImageView viewer = new ImageView(this);
         viewer.setImageResource(R.drawable.cat);
         layout.addView(viewer, new AbsoluteLayout.LayoutParams 
(AbsoluteLayout.LayoutParams.WRAP_CONTENT,  
AbsoluteLayout.LayoutParams.WRAP_CONTENT, 0, 60));
         setContentView(layout);
     }
}

I think cross compiled it using xmlvm with android-on-iphone option  
following the instructions in manual.pdf. Also I think there should be  
some instructions for the newbies on how to add iphone frameworks to  
the project and also which ones are needed. As I had to spend some  
time to figure this out myself as it wasn't in the manual.pdf when  
following the steps.

It successfully create iphone files. Well no errors were reported.

I then ran make in this directory which compiled the iphone files and  
launched the iphone simulator.

However when I run my application, it opens up a black window and then  
automatically shuts down.

I ran it via xcode and this is what I get in the IDE

2009-10-08 09:43:21.988 test[6829:207] *** Terminating app due to  
uncaught exception 'NSInvalidArgumentException', reason: '*** -

)
(gdb)



Any ideas? I was careful to write an app using only the features I was  
confident were supported by the android compat library.
