1：dex2smali dex文件转smail文件报错

Exception in thread "main" org.jf.util.ExceptionWithContext: F:\xxxx\xxxx\workspace\xxxx\xxxx\tiancity\sdk\xxxx\classes.dex is not an apk, dex file or odex file.
        at org.jf.dexlib2.DexFileFactory.loadDexFile(DexFileFactory.java:111)
        at org.jf.dexlib2.DexFileFactory.loadDexFile(DexFileFactory.java:54)
        at org.jf.baksmali.main.main(main.java:252)

 解决：去github 上换新的baksmali.jar

2：jar2dex   jar转dex过程报错

java -jar baksmali-2.5.2.jar -o smali classes.dex

Exception in thread "main" com.beust.jcommander.MissingCommandException: Expected a command, got -o
        at com.beust.jcommander.JCommander.parseValues(JCommander.java:725)

        at com.beust.jcommander.JCommander.parse(JCommander.java:287)
        at org.jf.baksmali.Main.main(Main.java:90)

解决：命令行使用错误

java -jar baksmali-2.5.2.jar disassemble -o smali classes.dex

3：recompileApk回编译，Could not smali file:

2021-11-30 14:47:46,165: *******************

解决：

dx.工具不支持java8语法，需要D8工具语法脱糖

莱姆达表达式 反编译 回编有错误，smali ->apk过程

4：打包签名加密方式，命令行代码：

apksigner.jar所在位置：安卓SDK\build-tools\25.0.0\lib\

#V2签名，默认V1V2，Android7.0 ，tool里使用的是25.0.0

#V3签名，8.0的apksigner.jar，如果使用27以上的 ，默认包含V1,V2,V3签名

安卓SDK提供的apksigner.jar工具，v1v2签名

java -jar apksigner.jar sign -verbose --ks zs.keystore --v1-signing-enabled false --v2-signing-enabled true --ks-pass pass:123123 --ks-key-alias zs.keystore --key-pass pass:123123 --out test_dst.apk test_src.apk

jarsigner.exe 所在目录：jdk1.8.0_281\bin

JDK提供的jarsigner.exe工具，v1签名

jarsigner -digestalg SHA1 -sigalg MD5withRSA -keystore ${keystore} -storepass  ${keystore.password} -keypass ${keypass} -signedjar ${signed.apkfile} ${unsigned.apkfile} ${keyalias} 

5：splitDex 分包的过程中，要copy的文件找不到

如果母包已经有多个smail，导致合并渠道SDK后，dex数量超过65536去分包，顺序混乱找不到文件。

比如要拷贝的IntrinsicsKt__IntrinsicsJvmKt$createCoroutineUnchecked$$inlined$buildContinuationByInvokeCall$IntrinsicsKt__IntrinsicsJvmKt$1.smali'这个文件 是在smali_classes2这里，但是从smali_classes2_classes2这里去copy，就会找不到目录

FileNotFoundError: [Errno 2] No such file or directory: 'F:/PycharmProject/pythonAPK2.0/workspace/xxx/xxxx/

decompile/smali_classes2_classes2/kotlin/coroutines/

experimental/intrinsics/IntrinsicsKt__IntrinsicsJvmKt$

createCoroutineUnchecked$$inlined$buildContinuationByInvokeCall$

IntrinsicsKt__IntrinsicsJvmKt$1.smali'

 解决方案：

在反编译后，把smali_classes2目录下的文件 copy到smail里

def decompileApk(source, targetdir, apktool="apktool_2.6.0.jar"):
    """
    Decompile apk
    """
    apkfile = file_utils.getFullPath(source)
    targetdir = file_utils.getFullPath(targetdir)
    apktool = file_utils.getFullToolPath(apktool)

    if os.path.exists(targetdir):
        file_utils.del_file_folder(targetdir)
    if not os.path.exists(targetdir):
        os.makedirs(targetdir)
    #添加–only-main-classes参数，针对有的母包assets下面也有dex文件而导致错误
    #cmd = '"%s" -jar -Xms%sm -Xmx%sm "%s" -v d -b -f "%s" --only-main-classes -o "%s"' % (file_utils.getJavaCMD(), heapSize, heapSize, apktool, apkfile, targetdir)
    cmd = '"%s" -jar -Xms512m -Xmx512m "%s" -q d -b -f "%s" -o "%s"' % (file_utils.getJavaCMD(), apktool, apkfile, targetdir)
    ret = file_utils.execFormatCmd(cmd)

    # -->如果母包中已经拆分出多个smali，复制到第一个smali，并删除，以便于重新计算
    smaliDir = targetdir + "/smali"
    smali2Dir = targetdir + "/smali_classes2"
    if os.path.exists(smali2Dir):
        file_utils.copy_files(smali2Dir, smaliDir)
        file_utils.del_file_folder(smali2Dir)
    return ret

6：回编结束，aapt copyRootResFiles过程报错

Unable to add 'kotlin/annotation/annotation.kotlin_builtins' to 'F:/PycharmProject/pythonAPK2.0/workspace/xxx/xxx/output.apk': already exists in archive

 解决方案：需要忽略

igoreFiles = ['AndroidManifest.xml','apktool.yml','smali','res','original','lib','build','assets','META-INF',
            'unknown',"smali_classes2","smali_classes3","smali_classes4","smali_classes5","kotlin"]

7：dex2smali，报警告信息

 解决方案：

# cmd = '"%s" -jar "%s" disassemble -o "%s" "%s"' % (file_utils.getJavaCMD(), smaliTool, targetdir, dexFile)
改为
cmd = '"%s" -jar "%s" -o "%s" "%s"' % (file_utils.getJavaCMD(), smaliTool, targetdir, dexFile)

8:合并R文件，R资源

doGenerateR
First type is not attr!
A/        (14756): First type is not attr!
*******ERROR*******

b''

b'First type is not attr!\r\nA/        (14180): First type is not attr!\r\n'

*******************

 原因是aapt 去合并 aapt2编译的包，resource.arsc文件，不能以attr开头。

：apktool工具地址：https://bitbucket.org/iBotPeaches/apktool/downloads/

9：运行找不到渠道SDK的R.styleable.xxxx

No static field AppCompatTheme_windowActionBar of type I in class Lcom/xxx/sdk/thirdparty/R$styleable; 
or its superclasses (declaration of 'com.xxxx.sdk.thirdparty.R$styleable' appears in /data/app/com.xxxx.xxx.xx-i22o2TufgzlaUEjh6xl9AQ==/base.apk!classes2.dex)

 解决方案：

U8SDK——declare-styleable自定义资源的合并

10:合并R资源，aapt报：

 解决方案：

 maxFuncNum = 65535 设置的过于临近，改为50000试试。

12：jar转dex,jar过大，需要分批加载问题

原因是，接入抖音渠道SDK，提供的jar包很大，大约30多M，导致打包在jar转dex这一步，因为dex只能装载65535个函数，而需要分批加载，具体错误如下：

2023-07-14 11:04:01,859: =======================jar to dex=======================
Error: Cannot fit requested classes in a single dex file. Try supplying a main-dex list.
