修改Android的apk包
解包
使用apktool工具，对apk进行反编译并解包 注：需使用java1.8来执行jar包
set PATH=E:\NVPACK\jdk1.8.0_77\bin;%PATH% java -jar %~dp0\apktool\apktool.jar d D:\MyTest1-Android-Test-arm64.apk // 对MyTest1-Android-Test-arm64.pak进行解包
如果不需要反编译java代码，需带上-s参数；不需要反编译资源，需带上-r参数
set PATH=E:\NVPACK\jdk1.8.0_77\bin;%PATH% java -jar %~dp0\apktool\apktool.jar d -s -r D:\MyTest1-Android-Test-arm64.apk // 不反编译java代码和资源，来对MyTest1-Android-Test-arm64.pak进行解包

打包
使用apktool将某个目录打包成apk
set PATH=E:\NVPACK\jdk1.8.0_77\bin;%PATH% java -jar %~dp0\apktool\apktool.jar b D:\MyTest1-Android-Test-arm64 // 将D:\MyTest1-Android-Test-arm64目录中的文件打包成apk
重签名
使用build-tools中的apksigner.bat工具对apk进行重签名
set PATH=E:\NVPACK\jdk1.8.0_77\bin;%PATH% set ApkSigner=E:\NVPACK\android-sdk-windows\build-tools\27.0.3\apksigner.bat set GameKeyStore=D:\Test1-key.keystore set GamePassword=Test111 set AnlignedName=Test1 java -Xmx4096M -Xss4m -Djava.ext.dirs="%ApkSignerDir%" -jar "%ApkSignerDir%\apksigner.jar" sign --ks %GameKeyStore% --ks-pass pass:%GamePassword% --ks-key-alias %AnlignedName% --in %~dp0\MyTest1-Android-Test-arm64\dist\MyTest1-Android-Test-arm64.apk --out %~dp0\MyTest1-Android-Test-arm64_signed.apk
注1：build-tools 27.0.3可以从这里下载
注2：由于apk有2GB，size比较大，会导致java进程崩溃，因此通过-Xmx来设置最大java堆的大小，通过-Xss设置java线程栈的大小
resources.arsc of installed APKs to be stored uncompressed and aligned on a 4-byte boundary
如果报如下错误，需要在打包与重签名中间，增加一个压缩对齐步骤
adb: failed to install F:\GameRepack\apktool\MyTest1-Android-Test-arm64.apk: Failure [-124: Failed parse during installPackageLI: Targeting R+ (version 30 and above) requires the resources.arsc of installed APKs to be stored uncompressed and aligned on a 4-byte boundary]
注：TargetSDKVersion从28改成30之后，出现此问题
压缩对齐
"%ApkSignerDir%\zipalign.exe" -f 4 %~dp0\MyTest1-Android-Test-arm64\dist\MyTest1-Android-Test-arm64.apk %~dp0\MyTest1-Android-Test-arm64\dist\MyTest1-Android-Test-arm64_align.apk
注：压缩对齐之后，再对%~dp0\MyTest1-Android-Test-arm64\dist\MyTest1-Android-Test-arm64_align.apk进行重签名
对于keystore秘钥可使用jdk1.8中的keytool工具来创建
set PATH=E:\NVPACK\jdk1.8.0_77\bin;%PATH% keytool -genkey -v -keystore Test1-key.keystore -alias Test1 -keyalg RSA -keysize 2048 -validity 100000
