Hello all, This is Shengxin. I am with Java for over 12 years starting from JDK 1.2. I love the open-source products/ideas introduced by Sun Microsystems. However, Sun did not survive well and they didn't make a lot of profits from Java products. I am a newbie Android developer. Being able to develop Android apps in Java allows me to learn Android SDK pretty fast, I found my knowledge of Swing, Thread and Networking in Java helps a lot. Recently I published my first app "Secret Locker" on Android Market at https://market.android.com/details?id=com.shengxin.keepsecret. Although so far the number of downloads is shameful, I still feel fruitful because I can do in Android! I can see the trend that smart phones and tablets will play more and more important roles. I'd like to share my success and failures with others here.
