编译apktool_v2.2.1出错

按照这里的编译apktool的方法：

https://ibotpeaches.github.io/Apktool/build/

编译v2.2.2及后续版本都没有问题，但是对于v2.2.1的时候，就出现了错误。起初在我的macOs上是这样的：

都是编译的时候进行了Test，然后Test没有通过的导致的编译出错。然后我试试在我的ubuntu16.04上看看。开始由于是OpenJDK，我怕这个可能有影响，然后卸载了OpenJDK, 再重新下载oracle JDK，然而还是有问题：

brut.androlib.BuildAndDecodeTest > classMethod FAILED

这下就只有一个错误了，但是还是编译出错。然后这里的

https://network.informatica.com/thread/17212

回答给了我启示，即将

java.io.tmpdir=<your specific location>

。然后我就找一下可能是哪里用到了

java.io.tmpdir

。

搜到了这个。

cqq@ubuntu:~/repos/apktool-dev/Apktool-2.2.1/Apktool-2.2.1$ grep -rn "java.io.tmpdir" *
brut.apktool/apktool-lib/src/main/java/brut/androlib/res/AndrolibResources.java:726:                        parentPath.getAbsolutePath(), System.getProperty("java.io.tmpdir")));
brut.apktool/apktool-lib/src/main/java/brut/androlib/res/AndrolibResources.java:730:                parentPath = new File(System.getProperty("java.io.tmpdir"));

然后傻不啦叽的把

System.getProperty("java.io.tmpdir")

改成了自己指定了目录，以为万事大吉了，结果重新编译还是一样的问题。

后来又再仔细看看出错的地方：

brut.androlib.Androlib.buildUnknownFiles(Androlib.java:601)

，编译的时候应该是Test中的代码没有通过才对啊，为啥要去改源码。。。。

然后找到这里：

brut.apktool/apktool-lib/src/test/java/brut/androlib/BuildAndDecodeTest.java

的

beforeClass

方法：

sTmpDir = new ExtFile(OS.createTempDirectory());

使用

brut.util.OS

类的

createTempDirectory()

方法创建了一个tmp目录。

其中

createTempDirectory()

方法为：

public static File createTempDirectory() throws BrutException {
try {
File tmp = File.createTempFile("BRUT", null);
if (!tmp.delete()) {
throw new BrutException("Could not delete tmp file: " + tmp.getAbsolutePath());
}
if (!tmp.mkdir()) {
throw new BrutException("Could not create tmp dir: " + tmp.getAbsolutePath());
}
return tmp;
} catch (IOException ex) {
throw new BrutException("Could not create tmp dir", ex);
}
}

即使用

File.createTempFile("BRUT", null);

创建了

/tmp/BRUTxxxxxx

目录。

测试了一下这个方法的功能。

$ cat Test.java
import java.io.File;

public class Test{
public static void main(String[] args){
try{
File.createTempFile("test_cqq", null);
}catch(Exception e){
e.printStackTrace();
}
}
}
$ javac Test.java
$ java Test
$ ll /tmp|grep test_cqq
-rw-rw-r--  1 cqq  cqq     0 Dec 28 22:48 test_cqq5553827309620261131.tmp

可能在apktool的Test代码中生成的tmp目录在之后寻找的时候已经不存在了。于是这里试试换成自己自定义的目录”/home/cqq/tmp”吧。

….醉了，结果还是不行：

brut.androlib.BuildAndDecodeTest > classMethod FAILED
brut.androlib.AndrolibException: java.io.FileNotFoundException: /home/cqq/tmp/testapp-orig/unknown/nonprintable.file (No such file or directory)

后来又用

brut.androlib.BuildAndDecodeTest > classMethod FAILED

关键词搜到了官方仓库的bug issue。

https://github.com/iBotPeaches/Apktool/issues/1394

官方给的答案是：可能是因为有空格导致的。



然后我根据错误信息

brut.androlib.AndrolibException: java.io.FileNotFoundException: /home/cqq/tmp/testapp-orig/unknown/non printable.file (No such file or directory)

中的”printable.file”搜了一下，

cqq@ubuntu:~/repos/apktool-dev/Apktool-2.2.1/Apktool-2.2.1$ grep -rn "printable.file" *
brut.apktool/apktool-lib/src/test/resources/brut/apktool/testapp/apktool.yml:15:  non\u007Fprintable.file: '8'

brut.apktool/apktool-lib/build/resources/test/brut/apktool/testapp/apktool.yml:15:  non\u007Fprintable.file: '8'

然后看这个

brut.apktool/apktool-lib/build/resources/test/brut/apktool/testapp/apktool.yml

文件是很久之前建的，所以应该不是我手动改的，是官方自带的。

cqq@ubuntu:~/repos/apktool-dev/Apktool-2.2.1/Apktool-2.2.1$ ll brut.apktool/apktool-lib/src/test/resources/brut/apktool/testapp/apktool.yml
-rw-rw-r-- 1 cqq cqq 344 Oct 18  2016 brut.apktool/apktool-lib/src/test/resources/brut/apktool/testapp/apktool.yml

查看这个文件，原来这里面有

\u007F

这种操作！



然后把

non\u007Fprintable.file

改成

nonprintable.file

就编译成功了！
