Answer 1

It's easy (这很简单)

Get these tools: (获取这些工具：)

1) dex2jar to translate dex files to jar files (1） dex2jar将dex文件转换为jar文件)

2) jd-gui to view the java files in the jar (2） jd-gui查看jar中的java文件)

The source code is quite readable as dex2jar makes some optimizations. (源代码非常易读，因为dex2jar进行了一些优化。)

Procedure: (程序：)

And here's the procedure on how to decompile: (这是关于如何反编译的过程：)

Step 1: (步骤1：)

Convert classes.dex in test_apk-debug.apk to test_apk-debug_dex2jar.jar (将test_apk-debug.apk中的classes.dex转换为test_apk-debug_dex2jar.jar)

d2j-dex2jar.sh -f -o output_jar.jar apk_to_decompile.apk
d2j-dex2jar.sh -f -o output_jar.jar dex_to_decompile.dex

Note: In the Windows machines all the .sh scripts are replaced by .bat scripts (注意：在Windows机器中，所有.sh脚本都替换为.bat脚本)

Step 2: (第2步：)

Open the jar in JD-GUI (在JD-GUI中打开jar)
