Eclipse import Android2.2 Email source code
(//android/packages/apps/Email/)，build failed，一直有compiler
error，花了兩天的時間，終於搞定

1. the
   import android.provider.Calendar cannot be resolved
   - root cause :
   android.provider.Calendar是Android internal
   package，沒有放在sdk裡，要去找出這個包含Calendar的jar檔(/out/target/common/obj
   /JAVA_LIBRARIES/framework_intermediates/classes.jar)，然後在Eclipse  
   1. Right-Click your project to open properties
   2. Java Build Path->Add Library->User Library->User
      Libraries->New
   3. Made up a name & check the “System Library” option
   4. Select the library you created->Add JARs
   5. Make sure all JARs you need are added to the project, and click OK
2. mContext cannot be resolved
   – root cause: Android release的sdk和source
   code不mapping，必需自行用Linux重新build過Android.jar，from device directory, 『make
   sdk』 will generate android.jar to
   ./out/host/linux-x86/sdk/android-sdk_eng.user_linux-x86/，接著用新build的
   Android.jar換掉原本的，就大功告成了
3. source code not found problem
   – 在trace Android source code，無法看到source的問題，可以把整個source tree，放到
   android-sdk-windows/platforms/android-8/sources/下，重build workspace即可解決
