After enabling proguard in my react native project, I've been getting countless notes and errors from all the packages, com.facebook.react, okhttp3, okio, and every other 3rd party library that I'm using including org.reactnative.camera, com.lwansbrough.RCTCamera, com.horcrux.svg and more. Shouldn't the default proguard rules already take care of some of the default packages?
After countless hours looking for solution that includes the obvious -dontnote and -dontwarn, as well as attempting to -keep all the classes mentioned, each time I manage to get rid of a couple of the warnings there is always more warnings.
Do I really have to manually go through every single reference to use proguard? Sometimes I don't even know which class to keep and ignore when using other libraries. Please help.

:app:transformClassesAndResourcesWithProguardForDebug FAILED
FAILURE: Build failed with an exception.
There´s a big log output from Gradle and I know I must clean up the proguard-rules.pro eventually but why does it work on android 6.0.1 and not on android 4.4.2. The log end with "Build failed with an exception" and I try to "Run with --stacktrace " but cant see the exception
I solved it.
The reason was in app build gradle I was using play-services 11.4.0 and firebase 11.4.2.
Somehow I missed syncing them to use the same version..
I have updated my support lib to 26.0.1, but release build is failed.

Not understanding due to which library proguard is failing.
proguard file
app level build.gradle
Error log
It's not support library issue,
I using library called branch.io ,i am added it's dependency end with "+".So it's updated and that has some progaurd rules.
After adding ProGuard rules for all libraries I am using, I still get this warning:
Warning: there were 14 unresolved references to classes or interfaces.
You may need to add missing library jars or update their versions.
If your code works fine without the missing classes, you can suppress
the warnings with '-dontwarn' options.

I know that I can probably use the -dontwarn option to get rid of this warning, but therefore I need to know which packages/classes/interfaces cannot be resolved. Android does not support a global "-dontwarn".
In the log file I find so many Notes and Warnings, but none of them seem to relate the above message.
If you receive a Warning: there were X unresolved references to classes or interfaces then look for lines in your build log that contain the word Warning, such as this:
Warning: com.package.Class1: can't find referenced class org.library.Class2
Lines like this will tell which classes ProGuard is trying to work on and which classes can't be found in the input jars. In the example above, class Class1 would reference Class2 of a library but Class2 was not found in the build path.
As you mentioned, you can simply add -dontwarn <class regex> to ignore those warnings but ideally you should check them one-by-one to make sure that your configuration is correct and all required dependencies are being imported correctly.
I get the following message from Proguard and I suspect the reason my app is not working has to do with them. But I am not sure what to do with the message:

Trying to build an Android app via SBT, I find that I can android:package just fine unless I add "net.databinder.dispatch" %% "dispatch-core" % "0.11.2" in to libraryDependencies. If I add it, then I get the following (extremely long) Proguard error (full text):

preceded by a few thousand lines. android:compile works fine with or without Dispatch added.
Looking at the dispatch-classic docs suggests that Dispatch does not work well with Android, but mentions that the "future move to a different backend" (presumably implemented in the latest versions of dispatch) will rectify this.
I can't find any information about Dispatch and Android other than what's available for dispatch-classic.
Does the issue still exist? Should I just use a different library? Is it possible to modify my proguard-sbt.txt to make sure android:package can run?
It seems that Dispatch now plays nicely with Android. My issue previously was that, unknown to me, my proguard settings were being re-generated by sbt for every compile. Adding in -donwarn ** to my proguardOptions in my .sbt file fixes the above errors (although I should probably track down the more specific packages that need to be -dontwarn'd in the future).
With that being said, it seems that Dispatch's heavy-duty dependencies do pose a problem with the Android development pipeline: running android:package maxes out all 6 of my CPUs and uses > 1 GB of memory. I'm way over the 65k dex limit. I think I'll go in a different direction.
