I was trying to export android application from project (Osmand) in Eclipse, the problem is that the proguard returned error code 1. Previously it throwed multiple warnings, so I used "-dontwarn" commands. Now the console sais this:
Proguard returned with error code 1. See console
Note: there were 227 duplicate class definitions.
You should check if you need to specify additional program jars.

java.lang.NullPointerException: Attempt to invoke virtual method ‘boolean java.lang.String.equals(java.lang.Object)’ on a null object reference
After debugging I have come to the conclusion that this is because that a value is not being passed from one activity to the other using putextra. This error only happens after enabling proguard. I am not aware of any keep rules to prevent this.
Currently my proguard file looks like this:

-keep class * extends com.bumptech.glide.module.AppGlideModule {

I don't understand proguard much. I have added rules as required by third party libraries. Other than that I use firebase and some classes with getter and setter methods. Activity has all its members as private. It is my understanding that there is a null pointer exception occurring due to inability to pass values between intents using putextra after enabling proguard and so the value of variable of the second activity remains null.
How to solve this and better write proguard rules?
First of all, you should give more details.
For example, you have a folder named model and inside you have a response model class.
Your FileTree
-model
--Response.java
If you do not specify this in proguard, the release app will not be able to use it as a reference, because proguard will change keys on memory. so you should remove your models from proguard. And finally, the app cannot wrong reference key on memory, after then you will get a null pointer error.
-keep class com.name.app.model.** { *; }
Thus, the model folder will not interfere with its classes within
I am enabling pro-guard in release mode but am getting this error after launching the app :

Most of libraries I used : Rxjava, Dagger .. don't need to add proguard rules .
So .. DO you know how to solve this, as this is the first time I am using prougard for a release build. Thanks .
I hit this when I enabled Java 8 featuers for my project. Debug builds ran fine but a signed apk wouldn't build with can't find ... access$100... error.
A clean project made it work again.
In Android Studio try Project -> Clean Project - it should always be the first thing to try as it often fixes issues.
Although it's an old question it's the first thing I hit when searching for my error message - so I'll leave this fix here for other's getting here.
I have a problem with using proguard, this first time I learned proguard, I use this and more link to make proguard but I have not been able to implement to my project,in my app I use libs google_play_services and actionbarsherlock. I kept trying and the result is always error. I had 2 days looking for how I can use proguard in my project, this time I was really confused, I need proguard in my application, this screenshot of my app (app_run).
this my proguard setting
-optimizationpasses 5
#When not preverifing in a case-insensitive filing system, such as Windows. Because this tool unpacks your processed jars, you should then use:
-dontusemixedcaseclassnames
#Specifies not to ignore non-public library classes. As of version 4.5, this is the default setting
-dontskipnonpubliclibraryclasses
#Preverification is irrelevant for the dex compiler and the Dalvik VM, so we can switch it off with the -dontpreverify option.
-dontpreverify
#Specifies to write out some more information during processing. If the program terminates with an exception, this option will print out the entire stack trace, instead of just the exception message.
-verbose
#The -optimizations option disables some arithmetic simplifications that Dalvik 1.0 and 1.5 can't handle. Note that the Dalvik VM also can't handle aggressive overloading (of static fields).

could anyone help me to give a way how to use proguard for my application?
really need help,thanks
Proguard is going to require "rules" for the libraries you use, and possibly your own code too. Many of these rules can be found https://github.com/krschultz/android-proguard-snippets/tree/master/libraries
I am working on an Android library project. I want to distribute this library as JAR to other developers.Before distributing the JAR I want to obfuscate it. I have tried using PROGUARD for this purpose, but its failing at the last step and says
The output jar is empty. Did you specify the proper '-keep' options?
Can anyone suggest what is going wrong ?

Can you kindly let me know whats causing this and how do I go about in fixing it.
Merging my project's proguard config with one from ${sdk.dir}/tools/proguard/proguard-android.txt did the trick.
This error mostly happens with 3rd party build systems (e.g. Maven), which don't know about default proguard config.
UPD: ...because of the following content of default config:
# Optimization is turned off by default. Dex does not like code run
