I started a tutorial on Cordova (see tutorial) and I just want to create my project. I wrote the command

./create /Users/monicamarcus/Documents/AndroidCourse com.example.tabletapp TabletApp

where the project does not exist yet. The answer was "Segmentation fault: 11". What does it mean? What should I do to get rid of it?

And another question: am I right that I am supposed to write the name of a non-existing project in the create command? Or should it be an existing project in Eclipse? Anyway, I tried it with the name of an existing project in Eclipse and I still get segmentation fault:11.

I want to write a method to change the phone number of a certain contact, identified by name. Here's the method:



As you see I tried several variants, but I always get zero rows updated and the phone number is not changed. Any idea how to get it done? Many thanks in advance for help.

I solved the problem in a very unexpected way. I fancy I should try to import the archive (the zip file containing the google-play-services directory.) And it worked!!! lol!

I re-installed google_play_services successfully and I have google_play_services-lib in my workspace. When I try to import it as a project in eclipse I use File-> Import->Existing Projects into Workspece -> Next -> Select root directory and then I find and select google_play_services-lib but finally it says "no project found to import". Why is that? How can I import this lib into eclipse?

I forgot to mention that I followed the steps at http://developer.android.com/google/play-services/setup.html

I am trying to use Google maps in a very simple app. I get as a warning that Google Play Service is out-of-date and that 3136100 is required. This is only a warning but my application does not show any map. I get again a button to click on it to update Google Play Service and when I click on it I get a Fatal exception:



So what can I do to see a map with my application? How do I update Google Play Service?

Sorry for my English ... "it leaves me working on ..."

I discovered which is the line that writes that output on the screen phone: it is the one starting with txt.setText(...
Ok, so this in fact answers my question and lefts me working on the program to get the list of contacts.... hopefully.

However, I decided to post the code for the method I use to list the contacts. Perhaps this way I'll get more chances to receive an explanation.

Now, after I added three contacts to my list of contacts, I wanted to show (list) them using a cursor and a ListAdapter. I don't get any error but instead of the list of contacts I see written on the screen only the following URI:

content://com.android.contacts/phone_lookup

What does it mean? I might show you the code too, but I'm not sure it is necessary.

Thanks for help!

You are a great programmer, Roland! Thanks a lot. I learned something from this.

Oh, I'm sorry. I must say that I get the NullPointerException when the last line is replaced by the commented-out line. That is, I get NullPointerException from the line

Thank you, Roland, for the advice. As I mentioned in my post, the NullPointerException occurs in the last line of the method. I tried to see which could be the null pointer, but I saw that none of the objects that appear in this line point to null. Maybe I miss something, but here's the stack trace. I cannot get any more information from the stack trace:



Perhaps you or someone else can help me to find out why I get the NullPointerException. Thank you in advance!

I am trying to insert contacts using the following method (in my activity class):



but I get the RunTimeException: aggregate contacts are created automatically. This happens in the last line of the method. If I use instead the commented one, I get NullPointerException. I don't really understand what's happening. How to get rid of the errors? I would very much appreciate your help.

Well, I found the opportunity to try the code on a real device and it works. The emulator is not that reliable... this is my conclusion.

I re-wrote the code so that it does only the downloading. Maybe this way one can give me an idea about what's wrong with it. I really need help. Can't get it to download the file



And strangely enough, sometimes the method connection.getContentLength() returns -1
