With appwidget you can easily share your Android app on your blog posts.
For example if you need to promote the Appchina app ( Market link for Appchina ) which has com.yingyonghui.market as package name, you only need to insert com.google.android.youtube in your editor and it will generate: * icon * name * developer * rating of the app.
