Program exceptions after Android JNI projects are obfuscated using proguard

Recently, a Android project uses the JNI mechanism. After packaging and using proguard to confuse release, we found thatProgramException.CodeYou cannot debug or see any abnormal logs. If you find proguard obfuscation on the internet, JNI-related classes may also be confused, especially the callback method in JNI. To verify the problem, after decompiling by dex2jar and other tools, we can see that the class of the JNI callback is obfuscated. To solve this problem, it is very easy to open proguard under the project directory. CFG, with the following content, the class name will be retained in case of confusion, without affecting JNI's call-keep class COM. your. jnicallback. class
