Without obfuscation using Proguard, everything is working fine.
When I enable Proguard, app gets crash on this line-
mStream.publish(liveStream.streamName, RECORD_TYPE);
where mStream is the instance of com.red5pro.streaming.R5Stream.
I'm using red5Pro library for broadcasting and not getting any stack trace. I have created an issue on Github also on this repo-
https://github.com/red5pro/streaming-android/issues/119
but didn't get any response yet.
I have tried solutions from other questions but still getting this error.
What should I do in my proguard configuration to resolve this problem?
I have already added following lines in my proguard rules-
-keep class com.red5pro.** { *; }
-dontwarn com.red5pro.**

Facing notorious java.lang.VerifyError. Initially problem showed up in Fabric. Was able to reproduce (with identical stacktrace) once set minifyEnabled true for debug build.
Caused by java.lang.VerifyError: Verifier rejected class com.evernote.client.conn.mobile.TEvernoteHttpClient: void com.evernote.client.conn.mobile.TEvernoteHttpClient.cancel() failed to verify: void com.evernote.client.conn.mobile.TEvernoteHttpClient.cancel(): [0x6] 'this' argument 'Reference: org.apache.http.client.methods.HttpRequestBase' not instance of 'Reference: org.apache.http.client.methods.AbstractExecutionAwareRequest'
void com.evernote.client.conn.mobile.TEvernoteHttpClient.flush() failed to verify: void com.evernote.client.conn.mobile.TEvernoteHttpClient.flush(): [0x7F] 'this' argument 'Reference: org.apache.http.impl.client.DefaultHttpClient' not instance of 'Reference: org.apache.http.impl.client.CloseableHttpClient' (declaration of 'com.evernote.client.conn.mobile.TEvernoteHttpClient' appears in base.apk)
at com.evernote.client.android.ClientFactory.createNoteStoreClient + 85(ClientFactory.java:85)
I see that typically java.lang.VerifyError issues are recognized as related to difference between code to compile and run against.
This is not the case since code runs just fine when minification is disabled.
The way I see this can be helped is making another rule, but I am failing to understand which classes need to be kept from this error details.
We are already doing
-keep class com.evernote.** { *; }
-keep interface com.evernote.** { *; }
-keep class org.apache.http.** { *; }
-keep interface org.apache.http.** { *; }
... and those classes don't get modified in any way. I've checked it using -printusage ./full-r8-config.txt instruction and checking the output. Classes mentioned in error details do not show up there.
UPDATE 1 day later:
Really strange thing going on here.
So far I have a verified backup plan: switching back to proguard fixes issue.
But in case if I want to stay with R8, here comes:
using -dontshrink, -dontoptimize and -dontobfuscate (all three at once) does no impact;
forcing specific apache.http version dependency does no impact;
I've checked mapping: neither Evernore SDK, nor Apache http classes don't get obfuscated;
issue pertains when app executed on api22 device (emulator, actually);
I was able to debug code once I had -dontobfuscate set. All goes well until Evernote's ClientFactory#createUserStoreClient decides to instantiate TEvernoteHttpClient - the moment program execution touches latter class's constructor - exception thrown.
It looks like it is all good to go, but this verifier fails.
Later update:
Issue filed as a bug for R8: https://issuetracker.google.com/issues/139268389. Please feel free to star it if facing similar situation (all code is in place but VerifyError is thrown)
Try to write below proguard rules.
-dontwarn com.evernote.client.conn.mobile.TAndroidTransport
-dontwarn com.evernote.client.conn.mobile.DiskBackedByteStore
-dontwarn com.evernote.client.conn.mobile.ByteStore
-dontwarn org.apache.commons.codec.binary.Base64
I made a simple app with external .jar library.
And going to obfuscator work with ProGuard.
But stuck with errors even had proguard rules.
I don't even know "borken class file" meaning about....
Can anyone know about this problem? Thanks. (Setting options or config attached as bottom section)

I got the same issue in my project,some suggest to reset the value ATTR_StacjMapTable to "dummy" in ClassConstants.java .then repack the proguard.jar
But I solve the problem is get the latest ProGuard in [http://proguard.sourceforge.net the use the latest proguard to make jar. goodlucky
I have a android app with 10 library projects and one application project.
2 of the library projects are using jackson library as dependencies. Here is the snipet from build.gradle for both of them
compile 'com.fasterxml.jackson.core:jackson-databind:2.4.4'
compile 'com.fasterxml.jackson.core:jackson-core:2.4.4'
compile 'com.fasterxml.jackson.core:jackson-annotations:2.4.4'
Now my app crashes with the following exception

Prior to crash, I could see the following lines in the log

had used a different

I have tried building the app without proguard using
minifyEnabled = false
Then it works fine. But that is not an option as I need to do obfuscation for my app.
I have tried the following in my proguard file.
-keep class com.fasterxml.jackson.** { *; }
-keepattributes *Annotation*
But it still gives crash.
Could you please tell me how to avoid this crash?
I'm getting the "No Class Def Found Exception" for the ToolBar in some kitkat devices like Samsung, ALTP etc. As per the below link(bug reported to google)
https://code.google.com/p/android/issues/detail?id=78377 #138 - asking the app to use old library classes, if the latest library is not supported is the only solution. I added these lines in my proguard-rules.pro:to fix this issue.
# Allow obfuscation of android.support.v7.internal.view.menu.**
# to avoid problem on Samsung 4.2.2 devices with appcompat v21
# see https://code.google.com/p/android/issues/detail?id=78377
-keep class !android.support.v7.internal.view.menu.**,android.support.** {*;}
`
I have fee in the xml format and proguard was not able to identify these classes,so added the below line too:
-keepclassmembers class * { *;}`
these are the only 2 changes i added extra. But after enabling proguard, my app performance is drastically reduced. It's taking lot of time to load pages and videos. This was not the case earlier. What might be the reason for this and how can I fix this issue. Is there any alternative for solving "NoClassDefFound Error".
Thanks in Advance..
Use this to solve your problem,
-keep class !android.support.v7.internal.view.menu.**,** {*;}
I have already answered for this issue,
NoClassDefFoundError: android.support.v7.internal.view.menu.MenuBuilder
I am using crashlytics in my app. It caught a crash in the app, but not telling the line of code where crash occured. It is showing the verify error, but not telling where it is. This link is a screenshot to the report. It is showing ??? about the crash, see this link. How to study this crash now? ._.
Preserve annotations, line numbers, and source file names
-keepattributes *Annotation*,SourceFile,LineNumberTable
If you are using custom exceptions, add this line so that custom exception types are skipped during obfuscation:
-keep public class * extends java.lang.Exception
-printmapping mapping.txt
To skip running ProGuard on Crashlytics, add the following.
This will help speed up builds so that we can ship and test even faster.
-keep class com.crashlytics.** { *; }
-dontwarn com.crashlytics.**
More Info: Follow this link to Configure Crashlytics with Proguard.
