AAPT 工具介绍

下面是取自"http://www.androidcn.net/wiki/index.php/Reference/aapt"的介绍

aapt stands for Android Asset Packaging Tool and is included in the tools/ directory of the SDK. This tool allows you to view, create, and update Zip-compatible archives (zip, jar, apk). It can also compile resources into binary assets.

aapt即Android Asset Packaging Tool , 在SDK的tools/目录下. 该工具可以查看, 创建, 更新ZIP格式的文档附件(zip, jar, apk). 也可将资源文件编译成二进制文件.

Though you probably won't often use aapt directly, build scripts and IDE plugins can utilize this tool to package the apk file that constitutes an Android application.

尽管你可能没有直接使用过aapt工具, 但是build scripts和IDE插件会使用这个工具打包apk文件构成一个Android 应用程序.

For more usage details, open a terminal, go to the tools/ directory, and run the command:

获取更多的实用信息, 请打开终端控制台, 到tools/目录下, 执行命令:

Linux or Mac OS X:

  ./aapt

Windows:

aapt.exe

AAPT 的帮助信息

执行上述命令,会在控制台打出相应aapt的信息:

Android Asset Packaging ToolUsage: aapt l[ist] [-v] [-a] file.{zip,jar,apk}   List contents of Zip-compatible archive. aapt d[ump] WHAT file.{apk} [asset [asset ...]]   badging          Print the label and icon for the app declared in APK.   permissions      Print the permissions from the APK.   resources        Print the resource table from the APK.   configurations   Print the configurations in the APK.   xmltree          Print the compiled xmls in the given assets.   xmlstrings       Print the strings of the given compiled xml assets. aapt p[ackage] [-f][-u][-m][-v][-x][-M AndroidManifest.xml] /        [-0 extension [-0 extension ...]] /        [-I base-package [-I base-package ...]] /        [-A asset-source-dir] [-P public-definitions-file] /        [-S resource-sources] [-F apk-file] [-J R-file-dir] /        [raw-files-dir [raw-files-dir] ...]   Package the android resources.  It will read assets and resources that are   supplied with the -M -A -S or raw-files-dir arguments.  The -J -P -F and -R   options control which files are output. aapt r[emove] [-v] file.{zip,jar,apk} file1 [file2 ...]   Delete specified files from Zip-compatible archive. aapt a[dd] [-v] file.{zip,jar,apk} file1 [file2 ...]   Add specified files to Zip-compatible archive. aapt v[ersion]   Print program version. Modifiers:   -a  print Android-specific data (resources, manifest) when listing   -c  specify which configurations to include.  The default is all       configurations.  The value of the parameter should be a comma       separated list of configuration values.  Locales should be specified       as either a language or language-region pair.  Some examples:            en            port,en            port,land,en_US       If you put the special locale, zz_ZZ on the list, it will perform       pseudolocalization on the default locale, modifying all of the       strings so you can look for strings that missed the       internationalization process.  For example:            port,land,zz_ZZ   -d  one or more device assets to include, separated by commas   -f  force overwrite of existing files   -j  specify a jar or zip file containing classes to include   -m  make package directories under location specified by -J   -u  update existing packages (add new, replace older, remove deleted files)   -v  verbose output   -x  create extending (non-application) resource IDs   -z  require localization of resource attributes marked with       localization="suggested"   -A  additional directory in which to find raw asset files   -F  specify the apk file to output   -I  add an existing package to base include set   -J  specify where to output R.java resource constant definitions   -M  specify full path to AndroidManifest.xml to include in zip   -P  specify where to output public resource definitions   -S  directory in which to find resources   -0  specifies an additional extension for which such files will not       be stored compressed in the .apk.  An empty string means to not       compress any files at all.

根据以上帮助信息,用aapt可以使用以下操作:

查看AAPT的版本

 ./aapt v

得到当前工具的版本:

Android Asset Packaging Tool, v0.2

使用AAPT列出资源包(.apk)文件列表

 aapt l[ist] [-v] [-a] file.{zip,jar,apk}   List contents of Zip-compatible archive.

可以用命令查看系统资源包的内容:

./aapt l framework-res.apk
META-INF/MANIFEST.MFMETA-INF/CERT.SFMETA-INF/CERT.RSAAndroidManifest.xmlassets/images/android_320x480.pngassets/images/boot_robot.pngassets/images/boot_robot_glow.png...assets/webkit/youtube.htmlassets/webkit/youtube.pngres/anim/accelerate_decelerate_interpolator.xmlres/anim/accelerate_interpolator.xmlres/anim/app_starting_exit.xml...res/raw-de/loaderror.htmlres/raw-de/nodomain.htmlres/raw/fallbackring.oggres/raw/loaderror.htmlres/raw/nodomain.htmlres/xml-en/autotext.xmlres/xml/apns.xmlres/xml/autotext.xmlres/xml/preferred_time_zones.xmlres/xml/time_zones_by_country.xmlresources.arsc

如果采用-v选项,会将所有文件的详细信息打印出来:

如果采用-a选项,会在上述文件列表之后,打印出android使用的符号表:

Resource table:mError=0x0 (Success)Package Groups (1)Package Group 0 id=1 packageCount=1 name=android  Package 0 id=1 name=android typeCount=13    type 0 configCount=1 entryCount=599      spec resource 0x01010000 android:attr/theme: flags=0x40000000      spec resource 0x01010001 android:attr/label: flags=0x40000000      spec resource 0x01010002 android:attr/icon: flags=0x40000000      spec resource 0x01010003 android:attr/name: flags=0x40000000      spec resource 0x01010004 android:attr/manageSpaceActivity: flags=0x40000000      spec resource 0x01010005 android:attr/allowClearUserData: flags=0x40000000      spec resource 0x01010006 android:attr/permission: flags=0x40000000      spec resource 0x01010007 android:attr/readPermission: flags=0x40000000      spec resource 0x01010008 android:attr/writePermission: flags=0x40000000      spec resource 0x01010009 android:attr/protectionLevel: flags=0x40000000      spec resource 0x0101000a android:attr/permissionGroup: flags=0x40000000... ...

这些符号表的格式还需要进一步研究才能搞明白 -_-!

使用AAPT打包资源文件

使用以下命令查看android的build系统是如何打包framework-res模块的:

cd ~/android/srcmake -n --debug framework-res

以下是从输出提取的关键步骤:

1. 第一步,生成资源apk包,由以下命令完成:

out/host/linux-x86/bin/aapt package -z -u -x  -M frameworks/base/core/res/AndroidManifest.xml -S frameworks/base/core/res/res -A frameworks/base/core/res/assets  -F out/target/product/generic/obj/APPS/framework-res_intermediates/package.apk

2. 第二步,为生成的资源包做签名:

java -jar out/host/linux-x86/framework/signapk.jar build/target/product/security/platform.x509.pem build/target/product/security/platform.pk8 out/target/product/generic/obj/APPS/framework-res_intermediates/package.apk.unsigned out/target/product/generic/obj/APPS/framework-res_intermediates/package.apk.signed

3. 第三步,为生成的包做对齐处理:

out/host/linux-x86/bin/zipalign -f 4 out/target/product/generic/obj/APPS/framework-res_intermediates/package.apk.unaligned out/target/product/generic/obj/APPS/framework-res_intermediates/package.apk.aligned

如此生成的framework-res.apk包可以被用来替换system.img中的资源包。(在CupCake前的稳定版本中测试可行)

具体步骤:

  1. 首先用生成的framework-res.apk替换在~/android/src/out/target/product/generic/system/framework中的同名文件。
  2. 用make snod生成新的system.img,替换sdk目录下的images/system.img
  3. 用-wipe-date参数启动emulator

使用AAPT解压资源包(.apk)

./aapt d xmltree framework-res.apk res/anim/fade_in.xml
N: android=http://schemas.android.com/apk/res/android  E: alpha (line=21)    A: android:interpolator(0x01010141)[email protected]    A: android:duration(0x01010198)=(type 0x10)0x12c    A: android:fromAlpha(0x010101ca)=(type 0x4)0x0    A: android:toAlpha(0x010101cb)=(type 0x4)0x3f800000
./aapt d xmlstrings framework-res.apk res/anim/fade_in.xml
String #0: interpolatorString #1: fromAlphaString #2: toAlphaString #3: durationString #4: androidString #5: http://schemas.android.com/apk/res/androidString #6:String #7: alpha

而没有经过编译的文件为:

<alpha xmlns:android="http://schemas.android.com/apk/res/android"       android:interpolator="@anim/decelerate_interpolator"       android:fromAlpha="0.0"       android:toAlpha="1.0"       android:duration="300" />

相应的R.java文件为:

package com.android.internal;public final class R {    public static final class anim {        public static final int accelerate_decelerate_interpolator=0x010a0004;        public static final int accelerate_interpolator=0x010a0005;        public static final int app_starting_exit=0x010a0007;        public static final int decelerate_interpolator=0x010a0006;        public static final int dialog_enter=0x010a0008;        public static final int dialog_exit=0x010a0009;... ...

也可以从符号表中得到这些索引值:

resource 0x010a0006 android:anim/decelerate_interpolator: t=0x03 d=0x00001132 (s=0x0008 r=0x00) (PUBLIC)

配合系统预定的framework/base/core/res/res目录的模版,就可以重建/res文件.
