Android App crashes on pre Android 5 devices

Question

I've updated my sdks, play services and so on, recently. When I run my app on devices/emulators with pre-Lollipop Android, it instantly with the following error:

java.lang.NoClassDefFoundError: com.google.firebase.FirebaseOptions

I'm not even using Firebase! The following is my gradle:

apply plugin: 'com.android.application'
android {
    compileSdkVersion 24
    buildToolsVersion '24.0.1'
    lintOptions {
        checkReleaseBuilds false
        abortOnError false
    }
    defaultConfig {
        applicationId "com.Myapp"
        minSdkVersion 15
        targetSdkVersion 24
        versionCode 2
        versionName "2"
        multiDexEnabled true
    }
    buildTypes {
        release {}
    }
    productFlavors {
    }
    dexOptions {
        javaMaxHeapSize "4g"
    }
}

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile files('libs/Kryptonz-sdk.jar')
    compile 'com.android.support:appcompat-v7:24.1.0'
    compile 'com.squareup.okhttp3:okhttp:3.4.1'
    compile 'com.github.greenfrvr:hashtag-view:1.2.1'
    compile 'com.google.android.gms:play-services:9.2.1'
    compile 'com.android.support:cardview-v7:24.1.0'
    compile 'com.android.support:recyclerview-v7:24.1.0'
    compile 'com.android.support:multidex:1.0.1'
    compile 'com.nostra13.universalimageloader:universal-image-loader:1.9.4'
    compile 'com.android.support:support-v4:24.1.0'
    compile 'com.android.support:design:24.1.0'
}

Is it possible that firebase is now included in play services? if true, how can I exclude it? Thanks a lot.

Answer 1

You can add dependency for Firebase

compile 'com.firebase:firebase-client-android:2.4.0'
