android - support libraries 23.2.0 cause app to crash

Question

My app works well with support libraries 23.1.0 or 23.1.1, but when i start using 23.2.0 it crashes on launch. I use five support libraries, but the ones that seem to make it crash are these two:

com.android.support:appcompat-v7:23.2.0

com.android.support:design:23.2.0

I have this issue on my galaxy nexus (API 17) but not on my Nexus 7 (API 22). Does anyone know what might be the problem? Here is my gradle file:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 23
    buildToolsVersion "23.0.2"

    defaultConfig {
        applicationId "com.ikarirobotics.aichordfinder"
        minSdkVersion 15
        targetSdkVersion 23
        versionCode 1
        versionName "1.0"
    }
    buildTypes {
        release {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    compile 'com.android.support:support-annotations:23.2.0'
    compile "com.android.support:appcompat-v7:23.2.0"
    compile 'com.android.support:design:23.2.0'
    compile 'com.android.support:cardview-v7:23.2.0'
    compile 'com.android.support:recyclerview-v7:23.2.0'
}

My layout is only a frame where i place the currently appropriate fragment:

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/fragment_container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="HomeActivity"
    tools:ignore="MergeRootFrame" />

Using the debugger I was able to discover that the crash happens when the main activity calls setContentView():

java.lang.reflect.InvocationTargetException

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.ikarirobotics.aichordfinder/com.ikarirobotics.aichordfinder.HomeActivity}: android.view.InflateException: Binary XML file line #36: Error inflating class android.support.v7.widget.Toolbar

My activity extends AppCompatActivity and i make use of the support action bar. Any ideas on how to fix this problem? :(

Answer 1

There seems to be a drawable mutation bug as being worked on Google with the 23.2.0 release. See the issue here. Reverting back to 23.1.1 should be fine until the next bugfix release.

Answer 2

Same thing happens to me. I partially fixed it reverting to 23.1.1 on support:design.
