java.lang.VerifyError: Rejecting class that attempts to sub-class erroneous class

While applying proguard to application m getting following verify error, I have seen other variants of verify errors but the following seems bit different, Proguard version: 5.3.3, Following MainApplication class extends android.app.Application and crash occurs at super.onCreate(); of onCreate() method

and in my proguard m having

,also I have mentioned

With analyze apk I can see following is not obfuscated without proguard

but same was obfuscated once I apply proguard,

correct me if m wrong, with following

it must not obfuscate application classes, why does above happen.

I had the exactly same error after resolving a lot of conflicts and rebases. I just cleaned the project and rebuilt it. It was working again like a charm.

When looking at the ContextWrapper . it is being stated, that:

Known direct subclasses

Application, BackupAgent, ContextThemeWrapper, IsolatedContext, MutableContextWrapper, RenamingDelegatingContext, Service

. of which not all are declared in your ProGuard -keep configuration.

you would need to add a rule alike the one below, which is a different approach, than adding all the individual sub-classes explicitly by their name. the public keyword is rather optional there, because those private / protected methods do not really need to be obfuscated, simply because the SDK sources package is publicly available for download. adding the -verbose switch into the configuration always makes ProGuard complain about «what to do», always with a hyperlink to the user manual.

java.lang.VerifyError: Verifier rejected class #607

h-amg commented Jul 12, 2019

The error occurs when I attempt to retrieve data from firestore while writing data works totally fine.

Exception message:

Caused by: java.lang.VerifyError: Verifier rejected class com.google.firestore.v1.WriteResponse due to bad method java.lang.Object com.google.firestore.v1.WriteResponse.dynamicMethod(com.google.protobuf.GeneratedMessageLite$MethodToInvoke, java.lang.Object, java.lang.Object) (declaration of ‘com.google.firestore.v1.WriteResponse’ appears in /data/app/com.app.android.name-1/split_lib_dependencies_apk.apk:classes2.dex)

The code runs normally anywhere but inside firestore onComplete callback method:

java.lang.VerifyError: Verifier rejected class. Code working fine in debug mode, but not throwing this error in release mode

Please help on this error.Below is error logcat:

Faced the same issue, I was using

I degraded the corountine to

It seems version 1.3.9 has some bugs according to kotlin documentation

If it happend to coroutines on Android, revert coroutines lib to 1.3.6 works for me. It seems that there is VerifyError bug in android coroutines lib version 1.3.7-1.3.8, and fixed after 1.4.0.

Downgrading dependencies did not work for me.

Remove @JvmStatic

If you create a suspend function be sure that you are not also using the @JvmStatic annotation for this method. Doing so will definitely throw this error.

Resolved. This was an unnecessary issue thrown after the use of Proguard.

Added -dontwarn for that class in the Proguard rules. The release is working perfectly fine.

java.lang.VerifyError: Verifier rejected class on Lollipop when using release APK

I get this error when I install my release APK on a 5.x device. The error does not occur when I push the same code from Android Studio, or if I run it on a 4.x device.

I inject my Toolbar and a custom NavigationDrawer in the class.

Is there something that would be different with the Butterknife codegen when using gradle assembleRelease ? I am not using ProGuard at all.

Here are my other Android build settings:

Cleaning out the build folder resolved the problem. Not sure why ART had an issue but Dalvik did not.

Running a gradle clean task was not clearing out my build folder all the way. I had to do it manually, but clean may work for some people.

In my case, the cause was slightly different.

Apparently, putting a synchronized statement inside a try/catch block causes the VerifyError , as reported here on SO and on the official bug tracker.

In my case the method that the error message said was ‘bad’, had some unknown faults. Changing from a Kotlin lambda to a regular loop solved my issue.

Before (With Error):

My app was working on most platforms but crashing immediately on Android 5.1. I started to suspect the new D8 dex compiler after reading Google info on how great it is. Disabling D8, so it uses the original DX compiler, is the only thing that worked for me. Project clean/invalidate caches didn’t fix it. I had some synchronized blocks, but removing them didn’t fix it. Turning off instant run didn’t fix it. Disabling proguard didn’t fix it.

Here is how you disable D8:
-Create a file called gradle.properties in the root of your project, if it doesn’t exist
-In it put this line: android.enableD8=false

You’ll get deprecated warnings. Hopefully Google actually fixes D8 before they fully remove the deprecated DX. I don’t know what in my code triggers it. I’m using Android Studio 3.2.1 with gradle version 4.6. Edit: I’ve reported this bug and Google developers are actively investigating
