So how come the code below fails for me? It gives me this error:
It seems to want to use java_lang_CharSequence.h, how can I avoid this?

com_home_imageviewer_ImageViewer.m:8:35: error:  
java_lang_CharSequence.h: No such file or directory
com_home_imageviewer_ImageViewer.m: In function ‘- 
[com_home_imageviewer_ImageViewer onCreate___android_os_Bundle:]’:

‘android_widget_Button’ may not respond to ‘- 
setText___java_lang_CharSequence:’
com_home_imageviewer_ImageViewer.m:132: warning: (Messages without a

make: *** [obj/com_home_imageviewer_ImageViewer.o] Error 1


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, 100));
         Button text = new Button(this);
         layout.addView(text, new AbsoluteLayout.LayoutParams 
(AbsoluteLayout.LayoutParams.WRAP_CONTENT,  
AbsoluteLayout.LayoutParams.WRAP_CONTENT, 0, 0));
         setContentView(layout);

         text.setText("fffff"));
     }
}
