I'm facing a very weird error right now. Basically, the app can search Google Places API using SearchView widget and show the results in Google Maps Android API V2, and the searchview widget is placed in action bar. I have referenced to this tutorial: http://wptrafficanalyzer.in/blog/android-searchview-widget-with-google-places-api-using-actionbarsherlock-library/
The app works fine when the searchable activity (I name it as SearchPlace) is the main and launcher activity. However, if I try to intent to this activity from another activity, the app crash. I got NullPointerException caused by handleIntent(). I have attached a portion of the Manifest file below SearchPlace is the name of my searchable activity.

The error log is attached below. It seems like my handleIntent() caused the error.

Can anyone help me plz ?
Thank you
Problem solved, modify the handleIntent() as
if(Intent.ACTION_SEARCH.equals(intent.getAction()))
{
String query = intent.getStringExtra(SearchManager.QUERY);
doSearch(query);
}
else if(Intent.ACTION_VIEW.equals(intent.getAction()))
{
getPlace(intent.getStringExtra(SearchManager.EXTRA_DATA_KEY));
}
