java.lang.NoClassDefFoundError: android/graphics/drawable/Icon

So far I got this error only for one user, who uses a rooted phone (SM-G900R7 Android 4.4.2). The error is like this:

I never use android.graphics.drawable.Icon in my code, all usages are from android.support.v4.graphics.drawable.IconCompat and I also never use that class in my code...

Btw my support library is version 26.0.0, my minSdkVersion is 15 targetSdkVersion is 26.

Thanks

Update

The issue is fixed in support library 27.0.0. If you update don't forget to change compileSdkVersion 27 as well.

What is happening?

Samsung devices with Android 4.4 crash like this when classes extending View define methods which return or take parameters of types that are not on classpath.

Starting with support library version 25.4.0 AppCompatImageView and AppCompatImageButton incorrectly overrides setImageIcon(Icon) method. Since Icon class was introduced in API 23 the app crashes on Samsung devices with API 19.

Similar thing happens when you try to override View.onApplyWindowInsets(WindowInsets).

Workaround for support library 26.1.0

Until this gets fixed in an official manner, If you're stuck with an older version of the support library, I made a modified version of appcompat-v7 where all traces of setImageIcon methods are removed. This means it won't crash on a Samsung with Android 4.4.

Put this at the bottom of your app's build.gradle:

repositories {
    maven { url "https://dl.bintray.com/consp1racy/maven" }
}

configurations.all {
    resolutionStrategy.eachDependency { details ->
        def requested = details.requested
        if (requested.group == 'com.android.support' && requested.name == 'appcompat-v7') {
            details.useTarget 'net.xpece.android:support-appcompat-v7-fixed:26.1.0-1'
        }
    }
}

This code will replace appcompat-v7 dependency with the described modified artifact.

Currently the only supported version of the fix is 26.1.0.

Warning: Understand the code before copy-pasting, and always exercise caution when getting code from unknown sources!

This issue was resolved in support library 27.0.0:

Android Gradle Plugin 3.x:

implementation 'com.android.support:appcompat-v7:27.0.0'
implementation 'com.android.support:support-v4:27.0.0'

Android Gradle Plugin 2.x:

compile 'com.android.support:appcompat-v7:27.0.0'
compile 'com.android.support:support-v4:27.0.0'

Note that you will also need to compile against SDK level 27.

This crash related to 25.4.0 version of support library.

Use 25.3.1 version.

Replace

compile 'com.android.support:appcompat-v7:25.4.0'
compile 'com.android.support:support-v4:25.4.0'

With:

compile 'com.android.support:appcompat-v7:25.3.1'
compile 'com.android.support:support-v4:25.3.1'

There are 2 options :

1. Have you changed the support library version ? this is quite classic library issue when the resources sometimes aren't 'saved' with the same name, or at all. Its not you, its google. Try to use support lib 25, and see if this error still occurs.
2. Try to clean the project and rebuild. Maybe you're kept with some old library versions in your build folder, and when you build your project it takes old values from it.
