一个使用命令行编译Android项目的工具类

一个使用命令行编译Android项目的工具类

简单介绍

编译apk项目须要使用的几个工具，基本都在sdk中，它们各自是(Windows系统)：

• 1.aapt.exe
  
  资源打包工具
• 2.android.jar
  
  Android编译工具
• 3.dx.bat
  
  dex文件生成工具
• 4.sdklib.jar
  
  生成apk
• 5.jarsigner
  
  签名工具

准备

在打包前。须要的环境例如以下：

1.JDK1.6+

2.Android SDK

3.上述5个工具的路径

打包过程

1.生成R.java文件

比方：

aapt package -f -m -J ./gen -S res -M AndroidManifest.xml -I D:\android_sdk_for_studio\platforms\android-22\android.jar

2.清空bin文件夹

清空上次生成的文件

3.编译java文件和jar包

javac -encoding GBK -target 1.5 -bootclasspath D:\android_sdk_for_studio\platforms\android-22\android.jar -d bin src\net\mobctrl\normal\apk\*.java gen\net\mobctrl\normal\apk\R.java -classpath libs\*.jar

4.使用dx工具打包成classes.dex

dx --dex --output=C:\Users\mochuan.zhb\newworkspace\BundleApk5\bin\classes.dex C:\Users\mochuan.zhb\newworkspace\BundleApk5\bin\

5.编译成资源文件

aapt package -f -M AndroidManifest.xml -S res -I D:\android_sdk_for_studio\platforms\android-22\android.jar -F bin\resources.ap_ --non-constant-id

6.使用sdklib.jar工具生成未签名的apk

java -cp D:\android_sdk_for_studio\tools\lib\sdklib.jar com.android.sdklib.build.ApkBuilderMain bin\MyCommond.apk -v -u -z bin\resources.ap_ -f bin\classes.dex -rf C:\Users\mochuan.zhb\newworkspace\BundleApk5\src

7.使用jarsigner对apk进行签名

jarsigner -verbose -keystore C:\test.keystore -storepass 123456 -keypass 123456 -signedjar C:\projectdemo-signed.apk C:\test.apk test

    }

}

使用

执行的时候，我们仅仅须要传入项目路径就可以：

public class BuildMain {

    private static final String PROJECT_PATH = "C:\\Users\\mochuan.zhb\\newworkspace\\BundleApk5";

    private static final int PACKAGE_ID = 5;

    public static void main(String[] args) {
        new BuildApkUtils(PROJECT_PATH, PACKAGE_ID).buildUnsingedApk();
    }

}

执行过程中。会将生成的命令打印出来：
