u can use astro to back up applications. so how to i post the apk? i have it
Here is an app that alllows you to download youtube videos as mp3 and mp4!
Index of /Backups/Apps
Download the youtube downloader app (I chose the 1st one). Then install it using your package installer. Open up the app and it will say "no videos". At this point you should see a triangle icon on your notification bar. Pull it down and click on it (it should say something about an update). Download that new apk called tubedroid. DON'T INSTALL IT YET!! First uninstall "youtube downloader" AND then you can install this new app called "tubedroid 2.5.2". You're all set
