构建Android自动编译持续集成系统

2010-12-06T13:45:00Z

因为我们专业，所以我们用Auto Build，所以我们用CI系统。

代码管理使用SVN，自动编译使用Ant，而持续集成使用Hudson，操作系统使用Ubuntu10.04。

1. 安装

1.1 安装JDK

sudo apt-get install sun-java6-jdk

1.2 安装Ant

sudo apt-get install ant-optional

1.3 安装Hudson

sudo apt-get upgrade
      wget -O /tmp/key http://hudson-ci.org/debian/hudson-ci.org.key
      sudo apt-key add /tmp/key
      wget -O /tmp/hudson.deb http://hudson-ci.org/latest/debian/hudson.deb
      sudo dpkg --install /tmp/hudson.deb

1.4 安装Android SDK

http://androidappdocs.appspot.com/sdk/index.html

2. Project配置

2.1 build.xml

http://androidappdocs.appspot.com/guide/developing/other-ide.html

按照官方的做法，使用自动生成的build文件就可以了。

<?xml version="1.0" encoding="UTF-8"?>
<project name="test-android">

    <!-- The local.properties file is created and updated by the 'android' tool.
         It contains the path to the SDK. It should *NOT* be checked in in Version
         Control Systems. -->
    <property file="local.properties" />

    <!-- The build.properties file can be created by you and is never touched
         by the 'android' tool. This is the place to change some of the default property values
         used by the Ant rules.
         Here are some properties you may want to change/update:

         application.package
             the name of your application package as defined in the manifest. Used by the
             'uninstall' rule.
         source.dir
             the name of the source directory. Default is 'src'.
         out.dir
             the name of the output directory. Default is 'bin'.
 
         Properties related to the SDK location or the project target should be updated
          using the 'android' tool with the 'update' action.

         This file is an integral part of the build system for your application and
         should be checked in in Version Control Systems.
   
         -->
    <property file="build.properties" />

    <!-- The default.properties file is created and updated by the 'android' tool, as well
         as ADT.
         This file is an integral part of the build system for your application and
         should be checked in in Version Control Systems. -->
    <property file="default.properties" />

    <!-- Custom Android task to deal with the project target, and import the proper rules.
         This requires ant 1.6.0 or above. -->
    <path id="android.antlibs">
        <pathelement path="${sdk.dir}/tools/lib/anttasks.jar" />
        <pathelement path="${sdk.dir}/tools/lib/sdklib.jar" />
        <pathelement path="${sdk.dir}/tools/lib/androidprefs.jar" />
        <pathelement path="${sdk.dir}/tools/lib/apkbuilder.jar" />
        <pathelement path="${sdk.dir}/tools/lib/jarutils.jar" />
    </path>

    <taskdef name="setup" classname="com.android.ant.SetupTask" classpathref="android.antlibs" />

    <!-- Execute the Android Setup task that will setup some properties specific to the target,
         and import the build rules files.

         The rules file is imported from
            <SDK>/platforms/<target_platform>/templates/android_rules.xml

         To customize some build steps for your project:
         - copy the content of the main node <project> from android_rules.xml
         - paste it in this build.xml below the <setup /> task.
         - disable the import by changing the setup task below to <setup import="false" />

         This will ensure that the properties are setup correctly but that your customized
         build steps are used.
    -->
    <setup />

</project>

2.2 local.properties

这个配置文件定义了Android SDK的位置

sdk.dir=${tool.android.sdk}

2.3 build.properties

这个文件里面定义了App的Package，以及生成App签名必须用的一些配置。

application.package=test.android
key.store=../test-android.keystore
key.alias=test-android
key.store.password=password
key.alias.password=password

3. Hudson配置

3.1 System Configuration

系统配置很简单，只需要配置JDK、Ant的位置就可以了。

比较有用的还有一项：E-mail Notification，如果你需要在build失败发送邮件的话，那么需要配置这一项。

3.2 Job Configuration

3.2.1 Source Code Management

1. 选择Subversion，并且设置好SVN的地址以及用户名、密码

2. 把Use update和Revert勾选上

3.2.2 Build Triggers

1. 勾选上Build Periodically，然后设置自动Build的时机，这里语法跟cron的语法是一样的。

例如：0 2 * * 1-6

2. 勾选上Poll SCM，设置每隔多长时间检测SVN的变更。

例如：0,15,30,45 9-23 * * 1-5

3.2.3 Build

Step1：删除上次编译的文件

rm –f test-android.keystore
rm –f –R ./test-android/gen
rm –f –R ./test-android/bin

Step2：生成Keystore

http://androidappdocs.appspot.com/guide/publishing/app-signing.html

例如：keytool -genkey -v -alias test-android -keyalg RSA -keysize 2048 -dname 'CN=xxx, OU=xxx, O=xxx, L=xxx, ST=xxx, C=xx' -validity 10000 -keypass password -storepass password -keystore 'test-android.keystore'

Step3：Invoke Ant

设置Targets：release –Dsdk.dir=$your-sdk-dir

例如：release –Dsdk.dir=/home/build/android-sdk-linux

3.2.3 Post-build　Actions

1. 勾选上Archive the artifacts，设置Files to archive：test-android/bin/test-android-release.apk

2. 勾选上E-mail Notification，可以设置发送邮件的对象和时机

经过以上步骤的设置，大功告成了。

专业就是这么简单！！！

简约而不简单——Android SimpleAdapter

2010-06-25T15:01:00Z

列表(ListView)、表格(GridView)，这在手机应用上面肯定是少不了的，怎样实现比较复杂一点的界面呢，先看一下我的效果图。

这样布局的情况是最基本的，也是最常用的，网上关于这样的布局有多种版本的实现方法，但是有很多需要自己实现Adapter，那样子是比较复杂而且没有必要的，因为我们有简约而不简单的SimpleAdapter。

1. ListView

SimpleAdapter的核心代码：

for (int i = 0; i < 10; i++) {
			Map<String, Object> map = new HashMap<String, Object>();
			map.put("PIC", R.drawable.pic);
			map.put("TITLE", "Test Title");
			map.put("CONTENT", "Test Content");
			contents.add(map);
		}
		SimpleAdapter adapter = new SimpleAdapter(this,
				(List<Map<String, Object>>) contents, R.layout.listitem,
				new String[] { "PIC", "TITLE", "CONTENT" }, new int[] {
						R.id.listitem_pic, R.id.listitem_title,
						R.id.listitem_content });

		listView.setAdapter(adapter);

listitem的Layout：

<?xml version="1.0" encoding="utf-8"?>

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_width="fill_parent" android:layout_height="?android:attr/listPreferredItemHeight">
	<ImageView android:id="@+id/listitem_pic"
		android:layout_width="wrap_content" android:layout_height="fill_parent"
		android:layout_alignParentTop="true" android:layout_alignParentBottom="true"
		android:src="@drawable/pic" android:adjustViewBounds="true"
		android:padding="2dip" />
	<TextView android:id="@+id/listitem_title"
		android:layout_width="wrap_content" android:layout_height="wrap_content"
		android:layout_toRightOf="@+id/listitem_pic"
		android:layout_alignParentRight="true" android:layout_alignParentTop="true"
		android:layout_above="@+id/listitem_content"
		android:layout_alignWithParentIfMissing="true" android:gravity="center_vertical"
		android:text="@+id/listitem_title" android:textSize="22px" />
	<TextView android:id="@+id/listitem_content"
		android:layout_width="fill_parent" android:layout_height="wrap_content"
		android:layout_toRightOf="@+id/listitem_pic"
		android:layout_alignParentBottom="true"
		android:layout_alignParentRight="true" android:singleLine="true"
		android:ellipsize="marquee" android:text="@+id/item_content"
		android:textSize="14px" />
</RelativeLayout>

2. GridView

SimpleAdapter的核心代码：

for (int i = 0; i < 10; i++) {
			Map<String, Object> map = new HashMap<String, Object>();
			map.put("PIC", R.drawable.pic);
			map.put("TITLE", "Test Title");
			contents.add(map);
		}
		SimpleAdapter adapter = new SimpleAdapter(this,
				(List<Map<String, Object>>) contents, R.layout.griditem,
				new String[] { "PIC", "TITLE" }, new int[] { R.id.griditem_pic,
						R.id.griditem_title, });

		gridView.setAdapter(adapter);

griditem的Layout：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:layout_height="fill_parent" android:layout_width="fill_parent"
	android:orientation="vertical">
	<ImageView android:id="@+id/griditem_pic"
		android:layout_width="wrap_content" android:layout_height="wrap_content"
		android:layout_gravity="center_horizontal">
	</ImageView>
	<TextView android:id="@+id/griditem_title"
		android:layout_width="wrap_content" android:layout_height="wrap_content"
		android:layout_gravity="center_horizontal" android:text="test">
	</TextView>
</LinearLayout>

Android2.2 新特性

2010-05-22T02:27:00Z

1. App installation on external storage media 把应用安装在外部存储器（SD卡）

http://androidappdocs.appspot.com/guide/appendix/install-location.html

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    android:installLocation="preferExternal"
    ... >

2. Data backup 用户数据备份

http://androidappdocs.appspot.com/guide/topics/data/backup.html

<manifest ... >
    <application android:label="MyApplication"
                 android:backupAgent="MyBackupAgent">
        <activity ... >
            ...
        </activity>
    </application>
</manifest>

3. Graphics 增强了图形处理的功能，特别是3D性能得到大幅度提升

New OpenGL ES 2.0 APIs in android.opengl.GLES20.
New ETC1, ETC1Util, and ETC1Util.ETC1Texture classes and utility methods for using ETC1 for texture compression.
New ImageFormat class.
New YUV image format API to enable compression from YUV to JPEG and manipulation of YUV data.

4. Media

New APIs in android.media.AudioManager for managing audio focus, transport control, transient loss of audio focus, ducking.
New broadcast intent for routing audio to SCO — ACTION_SCO_AUDIO_STATE_CHANGED with extras indicating new state.
New APIs in SoundPool to detect completion of sound-loading.
New APIs in SoundPool for auto pause and resume.
New APIs in MediaRecorder for specifying audio settings for number of channels, encoding and sampling rates, sampling rate.
New APIs for adding files to the media database, so that they are automatically scanned. SeeMediaScannerConnection.scanFile and MediaScannerConnection.OnScanCompletedListener.

5. Speech recognition and third-party recognition engines

The platform provides new speech-recognition APIs that allow applications to have a richer interaction with the available voice recognizer. For example, the APIs are sufficient to integrate voice recognition deeply into an IME.
The platform also provides a RecognitionService base class that lets third-party developers create plug-in recognition engines.
New RecognitionListener interface to receive callbacks.
New RecognizerIntent extras that let a requester app specify details as preferred language, minimum length in milliseconds, and so on.

6. Camera and camcorder

Changes to camera preview API to improve efficieny of preview pipeline.
New display orientation for camera (it can now work in portrait orientation).
New APIs in android.hardware.Camera for managing zoom level.
New APIs android.hardware.Camera.Parameters for querying and setting device camera settings such as focal length, exposure, zoom level, view angle, and others.
New thumbnail utility for video and image thumbnails.
New CamcorderProfile and CamcorderProfile classes enable apps to determine device hardware camera capablities.
New support in android.media.ExifInterface for retrieving GPS and focal length.

7. Device policy manager

New device policy management APIs allow developers to write "device administrator" applications that can control security features of the device, such as the minimum password strength, data wipe, and so on. Users can select the administrators that are enabled on their devices. For more information, see the android.app.admin classees or the example application code inDeviceAdminSample.java.

8. UI Framework

New UI modes "car mode" and "night mode" and UiModeManager let applications adjust their application UI for specific user modes.
New ScaleGestureDetector that lets Views detect and handle transformation gestures that involve more than one pointer (multitouch) using the supplied MotionEvents.
Improvements in the way that multitouch events are reported in MotionEvent objects.
The layout attribute fill_parent is renamed to match_parent. This affects both XML and Java code (seeViewGroup.LayoutParams). Note that the platform will continue to honor uses of fill_parent in legacy applications.
New layout attributes tabStripEnabled, tabStripRight, and tabStripLeft let developers customize the bottom strip of TabWidgets.
Better support for managed dialogs in Activity.

9. Accounts and sync

New method AddPeriodicSync() lets you schedule a periodic sync with a specific account, authority, and extras at the given frequency.

10. New manifest elements and attributes

For specifying the application's preferred install location (see App Installation on External Storage Media, above):
- New android:installLocation attribute of the <manifest> element. Specifies the default install location defined by an application.
For managing user data backup (see Backup manager, above, for more information):
- New android:backupAgent attribute of the <application> element. Specifies the component name of the BackupAgent subclass provided by the application to handle backup/restore operations, if any.
- New android:restoreAnyVersion attribute of the <application> element. Boolean value that indicates whether the application is prepared to attempt a restore of any backed-up dataset, even if the backup is apparently from a newer version of the application than is currently installed on the device.
For managing the platform's JIT compiler:
- New android:vmSafeMode attribute of the <application> element. Boolean value that specifies whether to disable JIT compiler optimizations when running the application.

11. Permissions

android.permission.BIND_DEVICE_ADMIN — Any device administration broadcast receiver must require this permission, to ensure that only the system can interact with it.
android.permission.KILL_BACKGROUND_PROCESSES — Allows an application to callkillBackgroundProcesses(String).
android.permission.BIND_WALLPAPER — Any WallpaperService must require this permission, to ensure that only the system can interact with it.
android.permission.SET_TIME — Allows an application to set the system time.
