I've been having problems with displaying Contacts in an AlertDialog, and I think I've found the
problem, but am still confused. The pertinent suspect part of my code is:
SimpleCursorAdapter mAdapter = new SimpleCursorAdapter(this,
android.R.layout.simple_list_item_1, mContacts,
new String[] { ContactsContract.Contacts.DISPLAY_NAME },
new int[] { android.R.id.text1 });
...Now "simple_list_item_1" is accepted by the compiler (the app runs in the Emulator), however when
I try to run this ListActivity, it bombs.
So after reading elsewhere about how to accomplish this task my eyes lit upon the aforepasted
"simple_list_item_1" - where is that? I didn't create any simple_list_item_1.xml file, and it doesn't exist in my \res\layout folder. So I (in Eclipse) right-clicked "simple_list_item_1" and selected "Open Declaration" and it invoked an err msg much or exactly like the one I see in the Debug Perspective about "Class File Editor | Source nout found | The JAR file ....\android.jar has no source attachment."
So...assuming this is the problem (there is no "simple_list_item_1.xml" in my \res\layout folder), what exactly is expected in this file (which I assume is simply a xml definition of what I want each Contact to display in)?
==============
Here is some LogCat data:
Here are the last lines in LogCat (it seems to die/hang once it gets to the ListActivity (ContactsActivity):

...and here are all of the Error msgs in one attempted run (open the app, try to invoke the ListActivity). Note the "THIS SHOULD NEVER occur" msg at the end:

simple_list_item_1 is a standard layout defined in the SDK, it's basically just a TextView with the id "android:id/text1", which is what you supply in your view identifiers.
Do you have the stacktrace of the crash? Because it's most likely not due to a missing simple_list_item_1 layout.
Create a new XML layout file using Eclipse wizard. The name of this file will replace simple_list_item_1 in your code:
In this layout, create a TextView (or any other container) element and call it text1:
Then SimpleCursorAdaptor will match your contact info and the text1 field in your layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="#+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="TextView" />

I am trying to run the simplest Hello World example app and looks like I can crash it even all it does is showing a TextView.
Steps to reproduce: Launch it in the emulator (1.5). Open the app - it shows the text view, then lock the phone by pressing "end call" button. Unlock by pressing "menu", then press "back". App crashes with "The process android.process.acore has stopped unexpectedly..." and Force Close button. It does not happen all the time, but I am able to reproduce it every time after wiping the user data at least.
I wonder if default Hello World is missing a detail which was considered too advanced for a hello world... Such problems with a basic example does not look very encouraging =)
Any idea what detail is missing and how to avoid this crash?

sounds to me more like something wrong with your emulator. Why dont you delete your emulator and create a new one and try again with a fresh project.
Hope that will help you. BTW why are you using emulator on 1.5?? Start to build applications for min 2.1.
Good luck.
I'm running an emulator targeting 2.3 (API Level 9). I've removed all downloaded apps (which includes any code that I've written) but I still get all of these logcat errors when I start up the emulator:

I'd like to try to clean these up so that I can know for sure that any errors I'm looking at are being caused by my code. Does anyone else get these error messages and do you fix them or just ignore them?
If they don't deal with your application, you can ignore them. There is nothing you can do as a developer to fix a manufacturer problem on other peoples phones or even yours for that matter (well short of a custom rom).
Edit: I'd also add that some errors/warnings are normal and are not to be of concern.
Common logging practice in Android is smth like:
public class MyClass
{
public static final String TAG=MyClass.class.getName();
// some stuff
Log.i(TAG, "My log message");
}
So when you're inspecting LogCat messages you can filter your logs using those TAG. This is way to ignore other logs.
I've created an AVD (version 2.2) using preferences set as default.

Unless you are experiencing actual problems, you can ignore error messages that occur during the startup of your emulator.

I'm assuming that you're working on Android, and that you're also referring to the exception in the middle of the log.
The SecurityException means you probably forgot to give the application the necessary permissions - you should change the Manifest XML file, as explained here.
