Android Framework Source Anti-compilation

Some devices crash in the framework code, but do not correspond to open source code, it is necessary to pull the framework inside the device and decompile the source code troubleshooting problems.

1. Get the Framework file:

ADB pull/system/framework

Get the content under the Framework folder, There may be framework.jar and Framework.odex, if the Framework.jar decompression out has Dex then decompile Dex can, if Framework.jar inside without Dex need to first decompile Framework.odex file to Dex file;

2. Decompile the Odex file:

Pull Framework folder when it is best to get it all, because there is a dependency on the anti-compilation, in the framework folder to get the anti-compilation do not worry about the lack of reliance on the problem;

(2) Generate Dex file

-jar smali-2.2. 2  -jar smali-2.2. 2. Jar Assemble out

(3) Generate JAR file

dex2jar-2.0  out.dex# use JD-gui to view Out-dex2jar.jar
