This error happens with some versions of Android. I tested with Android 6.0 and Android 5.0 and did not give error. However I went to test with Kit Kat and some cell phones of the Moto G1 gave error.

Look at the build. Gradle

apply plugin: 'com.android.application'

android { compileSdkVersion 24 buildToolsVersion "24.0.1"

defaultConfig {
    applicationId "br.com.appvis.appvis"
    minSdkVersion 16
    targetSdkVersion 24
    versionCode 1
    versionName "1.0"
    multiDexEnabled true
}
buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

}

dependencies {

testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:24.2.1'
compile 'com.google.android.gms:play-services:9.4.0'
compile 'com.android.support:design:24.2.1'
compile 'com.android.support:support-v4:24.2.1'
compile 'com.android.support:recyclerview-v7:24.2.1'
compile 'com.android.support:cardview-v7:24.2.1'
compile 'com.google.firebase:firebase-ads:9.4.0'
compile 'com.squareup.picasso:picasso:2.5.2'
compile 'com.android.support:multidex:1.0.1'
compile 'org.parceler:parceler:1.0.3'
compile 'org.parceler:parceler-api:1.0.3'
compile 'br.com.livroandroid:android-utils:1.0.5'

}

Answer 1

I saw that you have already enabled Multidex, so to complement, you should create a class and make a extends in class Application package android app. and call the install method of the Multidex class by passing its context.

public class MyApplication extends Application {

    @Override
    protected void attachBaseContext(Context base) {
        super.attachBaseContext(base);
        MultiDex.install(this);
    }
}

Done that, go to the Androidmanifest.xml and change or insert the following line:

<application
        android:allowBackup="true"
        android:name=".MyApplication" <-- Classe criada aqui -->
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
...
</application>

From the outbuildings, I saw that you appear to be using the lecheta book, right?
