samsung multiscreen Proguard conflict with exoplayer

I want to release my app but in proguard step I face a problem. it Generate some warning when I add lobmok ( or be more specific when I add samsung-multiscreen jar file) as follows :
Warning:com.google.android.exoplayer.MediaCodecAudioTrackRenderer:
can't find referenced class android.media.PlaybackParams
Warning:com.google.android.exoplayer.audio.AudioTrack: can't find

library class android.view.Display
Warning:com.google.android.exoplayer.chunk.VideoFormatSelectorUtil:

When I add following line to proguard-rules.pro some of the them disappeared but When I launch to the application it crash.
-dontwarn lombok.**
Also try this :
-keep class com.google.android.exoplayer.** { *; }
I think it raise due to conflict between annotation used in exoplayer and multiscreen (lombok)
does anyone knows how to fix this issue ?

Finally I fixed this issue with following proguard-rule:
-ignorewarnings
-dontoptimize
-dontobfuscate
-dontskipnonpubliclibraryclasses
-ignorewarnings
-keep class com.samsung.** { *; }
-dontwarn com.samsung.**
-dontwarn com.samsung.multiscreen.BuildConfig
-dontwarn lombok.**

proguard issue in Gradle

I am trying build my APP I am getting the following error: All this time App used to generate the build properly.
After I upgraded my compileSdkVersion and build to 23, GMS to 8.1, AsyncHttpclient to 1.4.9. I am getting the following error.
Not sure what to do:

What could be wrong here?

If you havent added command in progruard yet then add.
-keep class com.google.android.gms.maps.** { *; }
-keep interface com.google.android.gms.maps.** { *; }
If you are using map you should check developer site. There is proguard in it already.
For map you may need to add below code. if you havent added.
# The Maps API uses custom Parcelables.
# Use this rule (which is slightly broader than the standard recommended one)
# to avoid obfuscating them.
-keepclassmembers class * implements android.os.Parcelable {
static *** CREATOR;
}
# The Maps API uses serialization.
-keepclassmembers class * implements java.io.Serializable {

The -dontwarn proguard configs for 'org.joda.**' dont seem to work..
I have "-dontnote **ILicensingService" in config and that does not appear to work.
The -dontwarn config for com.google.android.gms.** not working
The -dontwarn for java.util.** not working

In what file is your "snippet" with the -dontwarn flags? It doesn't look like you're ever telling your build.gradle file about that proguard configuration.
You have:
proguardFile getDefaultProguardFile('proguard-android-optimize.txt')
But you should also have:
proguardFile 'your_proguard_config.cfg'
so that it will use both the default android configuration and your configuration.

Exclude Java SE library from Android proguard

In Android, I have proguard with the following settings.
-dontpreverify
# Hold onto the mapping.text file, it can be used to unobfuscate stack traces in the developer console using the retrace tool
-printmapping mapping.txt
# Keep line numbers so they appear in the stack trace of the develeper console

# The -optimizations option disables some arithmetic simplifications that Dalvik 1.0 and 1.5 can't handle.

Some of my library, are directly imported from Java SE (Contains JApplet for example)
How I can exclude them from proguard? Note, I have pinyin4j-2.5.0.jar library in -libraryjars. I thought that's the way to tell proguard, "Hey, this is a library. Don't do anything on it, OK?" But, seems like proguard still trying to process pinyin4j-2.5.0.jar
I'm getting the following errors.

Some of you may comment that for library jars which contain Java SE only methods (like Applet, Swing, ...) cannot be used in Android. Nope. In fact, they run perfectly fine, as long as you consume their non-Java SE-only methods.
The full error log can be downloaded from here : https://www.dropbox.com/s/dns62f7gp6unusg/error-log.txt

If you are sure that these Java SE classes are not used, you can indeed ignore the warnings (as you have found in your own answer). An easier way to specify this:
-dontwarn java.beans.**
-dontwarn java.awt.**
-dontwarn javax.swing.**

It seems that your line

is not complete.
Update
But since the needed classes do not exist on android, you have to ignore these warnings.
But do not generally ignore obfuscation warnings, we had a serious bug (using an obfuscation.map in file), because we ignored all warnings.

I merely avoid the error by

It doesn't work completely out of box yet as I still experience crash in "after proguard generated" APK.
Is pretty hard for me to find out why it crashes, as the code is obfuscate.
If I specific dontobfuscate, I will get another set of problem during generation. A message "Conversion to Dalvik format failed with error 1" pop up without additional information. But, that's another set of different problem.

Any hints?

I've also faced this problem. As there's no official solution in the GA documentation yet, I made up this set of rules:
-keep class com.google.android.gms.analytics.**
-keep class com.google.analytics.tracking.**
-dontwarn com.google.android.gms.analytics.**
-dontwarn com.google.analytics.tracking.**
This skips obfuscation as well, but that should not be a problem for an external libary..

The initial warning indicates that FutureApis invokes File#setReadable(boolean,boolean), which doesn't exist on the target platform that you have specified for your build (apparently android-8 or older). ProGuard can ignore it, but it will be a problem if that code is ever executed on those older platforms. The documentation of Google Analytics specifies that android-7 is sufficient, so presumably ignoring it is fine.
The unexpected error indicates that V4 support class AccessibilityDelegateCompatIcs$1 extends Android class View$AccessibilityDelegate, which doesn't exist on the target platform that you have specified for your build (android-13 or older). In this case, ProGuard really needs that class to properly process the code. With an incomplete class hierarchy, the output would be a mess.
You can solve both problems by specifying a more recent build target in project.properties when compiling your release version. The missing classes and methods will be present in the corresponding android.jar, so ProGuard will have all the information it needs. Since these classes are just runtime library classes, used for compilation/optimization/obfuscation, they won't affect the output.

I ran into the same problem - I was able to suppress errors when creating ank for release - but when the application it falls, in those places where the classes to which swearing obfuscator. At the moment I have not solved this problem. What is interesting is that in debage mode when running the application through Eclipse - and it works perfectly.
