Solving the problem of confusing errors-the solution to the problem of packaging the signature

This problem is more annoying, mainly because of the use of laser push function, and then packaged files released apk when there is a problem, resulting in the following a lot of errors, but we do not worry, there is a solution.

The above error is caused by a feature jar package that uses Aurora push in the project, and there is a problem with packaging.
The following is a solution to the bill:
How do I confuse ignoring Jpush-sdk-release.jar in code?
1, please download the latest Proguard.jar,
and replace your Android SDK "Tools\proguard\lib\proguard.jar"
2. Add code to your proguard.cfg:
-dontwarn cn.jpush.**
-keep class Cn.jpush. * { ; }
3, please use sdk1.3.x and later version

Follow the above procedure to solve the problem.

The first step to download Proguard.jar, below I give my the jar package, can solve the problem: Proguard.jar
After downloading to the Android SDK "Tools\proguard\lib\proguard.jar" directory to replace the same name file.

The second part is code obfuscation, add the above two lines of code in the Proguard.cfg file below the root directory of the project file. If the project root directory does not have this proguard.cfg file, then create a new file with the same name.

Follow the above procedure to solve the problem perfectly. Record down, may be useful later, if help you solve the problem, remember to give a praise AH!!! ^_^ "Handshake"
