Android Code style guidelines

Java Rules

1. 正確處理 Exceptions: 不要直接 catch generic Exception

2. 不要使用Finalizer (try-finally)

• Effective Java 2nd - Item 7
• JLS 規格書不保證 finalizer 會被及時執行，也不保證一定會被執行。
• 在 finalizer 執行跟時間相關的操作，就可能發生錯誤。

A product flavor defines a customized version of the application build by the project. A single project can have different flavors which change the generated application

ex: set two different flavors of your app

productFlavors {
    develop {
        applicationId "com.your.app.1"
        versionName "1.0.0"
