Android appCompat issue with samsung and wiko

问题

currently I have a little problem with my application, everything works fine on most devices but on some samsung and wiko I get this error : java.lang.NoClassDefFoundError: android.support.v7.internal.view.menu.MenuBuilder

I saw some answers on the internet where they said to add the line below in the proguard file, in my case this doesn't work

 -keep class !android.support.v7.internal.view.menu.**, ** { *; }

My app is compound of 2 modules(so I have 2 proguard file), 1module is for the main app and the other is for a library

here is my gradle file for thr app module:

 apply plugin: 'com.android.application'

android {
compileSdkVersion 22
buildToolsVersion "21.1.2"

defaultConfig {
    applicationId "com.refresh.quickeer"
    minSdkVersion 16
    targetSdkVersion 22
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
    debug
            {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
            }
}
}

dependencies {
compile fileTree(dir: 'libs', include: ['*.jar'])
compile 'com.android.support:appcompat-v7:22.1.1'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.android.support:cardview-v7:22.1.0'
compile 'com.android.support:recyclerview-v7:22.+'
compile 'com.android.support:palette-v7:21.0.0'
compile 'com.xgc1986.android:parallaxpagertransformer:1.0.3'
compile project(':library')
}

Does somebody have a solution to this problem please ?

回答1:

Before encountering this issue I did not use proguard on my app. I resolved the issue by setting minifyEnabled true and using the following proguard config

-dontshrink    
-keep class !android.support.v7.internal.view.menu.**,** {*;}
-keepattributes **
-dontwarn **

I tested my app on appthwack before and after this fix to verify that it worked.

I know exactly what you are talking about, here is the Google

Here is what I use to fix `java.lang.NoClassDefFoundError: android.support.v7.internal.view.menu.MenuBuilder`:

-keep class !android.support.v7.internal.view.menu.**,android.support.** {*;}

Here is everything that works for Support v4 and v7:
