I’ve added a spinner to my android app and when I run my app in the emulator it crashes. Prior to that it ran fine. Here is my code for the spinner…
This is in my class…
public void populateSpinners(){
Spinner spinner = (Spinner) findViewById(R.id.spinner1);
ArrayAdapter<CharSequence> adapter = ArrayAdapter.createFromResource(
this, R.array.planets_array, android.R.layout.simple_spinner_item);
adapter.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner.setAdapter(adapter);
return;
}
This is in my string.xml…
<string name="planet_prompt">Choose a planet</string>
<string-array name="planets_array">
<item>Mercury</item>
<item>Venus</item>
<item>Earth</item>
<item>Mars</item>
<item>Jupiter</item>
<item>Saturn</item>
<item>Uranus</item>
<item>Neptune</item>
</string-array>
This is code I “borrowed” from here…
http://developer.android.com/resources/tutorials/views/hello-spinner.html
I added a break point after the spinner was initilazed and ran the app in debug mode. The debugger runs fine and reaches the breakpoint with no errors. However after the breakpoint, the debugger freezes and shows this…

And I see this….
I read that it means I’m missing the Android source. Is this correct? Why do I need the Android source? Isn’t the Android SDK enough? Or is there some other problem? I’m new to Java/Android (been programming for about a week now) and I’ve been muddling my way through things so please excuse me if this is a “noob” question. 😀 Thanks!
Here are the parts of my DDMS that show the error that is occurring…

Eclipse tries to access the Android source in order to help you debug the crash. There are some instructions online to attach the source to Eclipse, but they’re quite long-winded, and best left as an exercise for elsewhere (I used http://android.opensourceror.org/2010/01/18/android-source/ at some point).
If you’d like some help with the crash itself, can you paste the stacktrace from DDMS? (With the breakpoints disabled).
