Have been battling with Proguard all day and have tried many examples and solutions on the official Proguard site as well as StackOverflow.
I have a large project I need to obfuscate, which has a number of referenced library projects and Jars.
I am getting 725 warnings from proguard from 2 libs, com.google.common and twitter4j.
I can happily get the project to compile if I add the following:
-dontwarn com.google.common.**
-dontwarn twitter4j.**
However, the app crashes instantly on open, so this seems to just be a way of hiding an issue, not fixing it.
The proguard-project.txt is in the project root and its config is in the project.properties file as below.
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
Here is my proguard-project.txt file

These are the config I've used in the past for SQLcipher
-keep public class net.sqlcipher.** {
*;
}
-keep public class net.sqlcipher.database.** {
*;
}
I'll suggest you to add thoses 2 lines in your proguard file :
-dontwarn javax.management.**
-dontwarn org.apache.commons.logging.**
