Solution 1:

This problem is caused by code obfuscation and reference packages cannot be found.

You only need to add the following two lines in your proguard. cfg.

-Ignorewarnings
-Libraryjars libs/android-support-v4.jar

You can add the required jar as prompted by your project.

Note:

If the preceding two rows are not successfully packaged, You need to modify

The proguard. bat file in the android-sdk-windows \ tools \ proguard \ bin directory,

Open it in notepad and modify it as follows:

Set
Call % java_exe %-jar & quot; % PROGUARD_HOME % & quot; \ lib \ proguard. jar % *
Changed:
Call % java_exe %-jar & quot; % PROGUARD_HOME % & quot; \ lib \ proguard. jar % 1% 2% 3% 4% 5% 6% 7% 9
You can!

This method is to change the current SDK version to the same as the proguard. bat file contained in the previous SDK version!
