添加calendar.apk到android模拟器的尝试

   最近需要做一个android上面的calendar的项目。以前没有接触android相关的东西都要从头开始学习。

 

我尝试的方法

   弄了两天终于在ubuntu上面把android平台开发环境弄好了，在模拟器上写了两个小程序，熟悉了一下环境，想把android自带的calendar程序拿来看看，结果发现模拟器上面没有calendar程序，找了一下发现android源代码是有这个AP的，就把calendar工程用eclipse打开想直接编译成APK看看长得什么样子。结果打开发现一堆的错误，仔细看了一下发现是一些java相关的库没有加入到android.jar。

     好吧，自己动手，丰衣足食，参考了一下fix_android_sdk.py（http://code.google.com/p/android-scripting/source/browse/tools/fix_android_sdk.py?r=bd959f44d4b39cedfa156a361c3be033c2fc3433），写了一个函数自动编译calendar相关的java代码然后打包到adnroid.jar中去，把下面的代码保存成fix_android_sdk.py。然后运行

python fix_android_sdk.py "src_folder", "sdk_folder" 

就可以把calendar相关的代码加入到android.jar中去了.

测试了一下，这种添加方法，并没有把需要的库添加到模拟器上去，所以在运行的时候如果需要操作android.provider.calendar就会出问题。

解决办法，就是把calendar需要的库直接打包到calendar.apk中去，方法如下。

1. 把calendar需要的库打包成jar，修改fix_android_sdk.py单独生成一个jar（不加入到android.jar中）

2.在calendar工程中新建一个叫libs的packages，把单独生成的jar，添加到libs下面。

上面两步后，calendar基本上不crash了，但是从logcat中可以看到calendar还是找不到provider.calendar，这个应该是在AndroidManifest.xml中没有声明，所以系统找不到，我尝试来两种方法解决这个问题。

1.程序build system.img，用mmm命令把calendarprovider添加system.img中，这种方法我尝试可行，calendar工作起来没有什么问题

2.按照编译calendar的方法编译calendarprovider。

 

 

查了一下资料正确的添加方法是

在make  后

执行

. bulid/envsetup.sh

mmm /packages/apps/Calendar/

把生成的system.img, 替换sdk目录/platfroms/android-AOSP/images/ 下的system.img

这样这样calendar就直接被打包system.img中去了。

这样做后calendarprovider并不会被添加到SDK中，如果要在eclipse中使用，需要做下面的步骤

拷贝/out/target/common/obj /JAVA_LIBRARIES/framework_intermediates/classes.jar到SDK目录

然后

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
