Re: [android-beginners] Re: Including libraries in project
During compilation, Android tools use standard Java .class format, as you found out. However, during application packaging (I think) they are converted into Dalvik's special format, .dex, which does not use Sun's Java bytecode. If you list the contents of an .apk file, you will see one .dex file instead of multiple .class files, as would be the case with a regular Java application. http://en.wikipedia.org/wiki/Dalvik_(software) -- Kostya 17.07.2010 17:06, DanH пишет: That's not been my impression, and when I browse an Android class file with a hex editor it says CAFEBABE.

[android-beginners] Notification.FLAG_NO_CLEAR not working as expected
I'm setting my notification like this: notification.defaults |= Notification.FLAG_NO_CLEAR; I expect this to mean that pressing the clear button in the expanded notification screen will not clear this notification. But the button still clears the notification. I think this may be a permissions problem in my manifest. I currently have a uses permission android.permission.VIBRATE set. Do I need any other permissions to make a notification sticky? -- You received this message because you are subscribed to the Google Groups Android Beginners group. NEW!

Re: [android-beginners] Help, please - How to display videos as thumbs?
Hey I just saw that I forgot s.th. within getCount(), so I changed it to
public int getCount() {
//return mThumbIds.length;
if(vidUris!=null){
return vidUris.length;}
return 0;
}
The thing now is that I still cannot see any videos displayed in my
GridView, but I get a message saying: Sorry, but this video cannot be
played!
As I don't want to play the videos but only display them in the GridView
like in an directory, do I maybe have to use MediaStore.Video.Thumbnails
instead, which I just found when I googled a little...though I don't know
what I should do with it in my code...if someone could help me out here,
that would be really really great... Thanks

[android-beginners] Tabs + framelayout children
Hi, I'm playing around with APIDemo's Views-Tabs-Content by Intent. It seems that when I switched to a tab, there is a new additional FrameLayout child which contains the tab content. So if I clicked on Tab1, then it'll add one child to FrameLayout, then Tab2, adds the 2nd child and so on. Say I have all 3 children in FrameLayout, how do i know if I click on Tab1, which FrameLayout child does it corresponds to?

[android-beginners] If and How to get video thumbnails
Hi,
I am working on a video app. And I have created a GridView that shall
display any video stored on the sdcard. Currently it only displays the
name of the video file.
I wanted to ask if and how it would be possible instead of showing
only the name to also display thumbs (or a frame preview) of the
videos ?!?
I would be grateful for any help...thanks.

[android-beginners] Re: Including libraries in project
Really? That would make me feel much better. But older postings and some sources supported that in general external jars may not work under Android and that their corresponding source should be compiled with its SDK before they can be used - which throws reusability out of the window. In any case, then it makes no sense as to why the classes are not visible in the emulator even though I (finally) managed to include the jars in the apk - having them in the classpath does not do it. Including them in the assets dir will .. unless someone else knows of a better way to do it ( I did use the export and order and no it doesn't work).
