I am making an android app which requires to capture image using front camera using android service. Also we need to detect face in the image so obtained. But when calling the detectfaces() function, the app unfortuantely stops. I am posting the code for it here. Please help me find out where i am going wrong.
here is my code..!!!!

Does this help? http://www.vogella.com/articles/AndroidListView/article.html#listviewselection
And please put your code into
Code:
tags. It's not readable without it. So nobody will read it. ;)
This is a rudimentary android application that serves as an umpires strike/ball/out counter. There is a settings icon in the action bar of the MainActivity. When this icon is 'clicked on', a new Activity is started consisting of a PreferenceFragment, which consists of a checkboxpreference, and a Fragment that consists of 3 buttons. These buttons reset the stike_count, ball_count and total_outs_count to zero. I have spent a day on this and am having trouble figuring out how to manipulate integer variables in my MainActivity from button clicks in a seperate Activity's Fragment. Please point me in the right direction.

To modify anything in your activity from one of its child Fragments you would typically create an interface in the Fragment and have the activity implement that. That interface would either contain one method setting all three vars or multiple ones, one for each variable. To call the methods in the interface call getActivity() and typecast it to the interface.
Hello everyone.
I am trying to load the Images in an listview that the RSS provides me.
http://www.nutech.nl/rss is the rss i use.
i want to load the image in listview from these tags
<enclosure> </enclosure (
Code:
<enclosure url="http://media.nu.nl/m/m1nx89taa599_sqr256.jpg" length="None" type="image/jpeg"></enclosure>
)
Now i have tried several things i found on google but none worked or werent explaining enough.
Here is some of my main Codes

is there someone who could help me ?
thank you
After few months i still havent found a solution or idea.
anyone here has ?
Use a RSS parsing library
Use my AndroidWithoutStupid Java library. It is on GitHub. There is also an article about the usage on CodeProject.
Enclosure tag is usually used for mp3 files but it doesn't matter.
After getting the enclosure value using the MvNewsFeed class, you need to download it. Use MvAsyncDownload for that. Then, use BitmapFactory.decodeFile() or a similar method to display the image in an ImageView.
