Most of the YouTube app launches probably come from links on webpages that target YouTube videos. Oh and by the way, I can even use this application in the emulator (unlike the default YouTube application – it cannot be installed due to the locked account manager and inability to access Marketplace content directly). All I need is a parser that will get the YouTube video ID (which, by the way, is a part of the YouTube library I recently disassembled) from the URL and I am set to create a new YouTube application with deep system integration.
