In your manifest .xml change target-sdk to 19.!
I think you are targeting the wrong device. If memory serves me right, it sounds like you might be targeting Android Wear.
If you are developing a mobile application, change your target sdk to API 19

It sound like you might be trying to use getResources() before they are technically ready.
If you have this:
String APP_ID = getResources().getString(R.string.APP_ID);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
...
}
Do this instead:
String APP_ID;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
APP_ID = getResources().getString(R.string.APP_ID);
...
}

You're trying to initialize a member variable where the initialization is using this as Context. In this case it's the getResources() call. You can only use the Activity as a Context in onCreate() or later in the activity lifecycle.
Specifically (from question comments), change this:
String APP_ID = getResources().getString(R.string.APP_ID);
to something like:
String APP_ID;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
APP_ID = getResources().getString(R.string.APP_ID);

I have a problem with downloading XML file from Internet in Android. I wrote some code and it works on Android 2.3 emulator. However, it doesn't work on Android 4.03 emulator and it doesn't work on real Android 4 device either.
Here is my code:
public String getXmlFromUrl(String url) {
String xml = null;
try {
// defaultHttpClient
DefaultHttpClient httpClient = new DefaultHttpClient();
HttpPost httpPost = new HttpPost(url);
HttpResponse httpResponse = httpClient.execute(httpPost);
HttpEntity httpEntity = httpResponse.getEntity();
xml = EntityUtils.toString(httpEntity);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
} catch (ClientProtocolException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
// return XML
return xml;
}
I have error on line:
HttpResponse httpResponse = httpClient.execute(httpPost);
Here is log from LogCat:

What can I do with it?
You're performing a (potentially slow) network operation on the main thread. If your target SDK is 11 (Honeycomb) or higher this will throw a NetworkOnMainThreadException on Honeycomb or above, because this behaviour can block the UI and lead to an unresponsive app. Even on pre-Honeycomb devices this behaviour is discouraged.
You could use an AsyncTask to get around this, loading the data in its doInBackground(..).
You are using network feature on the main thread. You need to use AsyncTask to accomplish this.
Starting from Honeycomb Strictmode checking is enabled by default. So Network operations raise an exception. Strictmode was not enabled in Gingerbread. Hence it is working in gingerbread but not in ICS
My problem is in starting new activities.
I have ListView, items of it are defined from string-array by this code:
listBanksUA = getResources().getStringArray(R.array.list_banks_ua);
setListAdapter(new ArrayAdapter<String(this,android.R.layout.simple_list_item_1,listBanksUA));
List is defined in layout as:
<ListView android:id="#+id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:drawSelectorOnTop="false"/>
So, I'd like to start new activity after click on item of ListView. Sure, I have created new XML-layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<ListView
android:id="#+id/listRegions"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:drawSelectorOnTop="false"/>
</LinearLayout>
and Java-class for it: ListRegionsActivity.class.
In my first Activity I use the follow code to start new Activity:
#Override
protected void onListItemClick(ListView l, View v, int position, long id)
{
startActivity(new Intent(MainActivity.this,ListRegionsActivity.class));
}
and after clicking in started application I'm getting an error, that my application has been closed with advice to try again. Sadness...
So, really I'll be glad for any help for me.
BTW: of course, I added new activity to manifest file.
UPD: my LogCAT with Error flag

UPD: the problem is solved. The reason was in incorrect mistake in opening avtivity - setContentView should be deleted.
Since you did not showed us the LogCat trace, I can do the guess.
Try this in the ListView click listener
MainActivity.this.startActivity(new Intent(MainActivity.this,ListRegionsActivity.class))
And dont forget to add the new activity in your manifest.
Check you're not importing android.R in your app instead of your.package.R
