App crashing on Android API less than 5.0(lollipop)

Question

The problem I am facing is that my android application works well on devices having API 5.0 and above but crashes on devices having Kitkat(4.4) and its corresponding lower versions.I know that its somehow related to the build tools in my gradle file,but still not able to figure out the problem.Could someone please help me out with this.

This is my gradle file,

     buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }

    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'
apply plugin: 'android'

repositories {
    maven { url 'https://maven.fabric.io/public' }
    maven { url 'http://clinker.47deg.com/nexus/content/groups/public' }
}


android {
    compileSdkVersion 22
    buildToolsVersion '22.0.1'

    defaultConfig {
        applicationId "com.abc.example"
        minSdkVersion 10
        targetSdkVersion 22
        multiDexEnabled true
        versionCode 12
        versionName "1.0"
    }
    buildTypes {
        release {
            multiDexEnabled true
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    android {
        packagingOptions {
            exclude 'META-INF/LICENSE'
        }
    }
    android {
        packagingOptions {
            exclude 'META-INF/NOTICE'
        }
    }
}



dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile('com.fortysevendeg.swipelistview:swipelistview:1.0-SNAPSHOT@aar') {
        transitive = true
        exclude module: 'httpclient'
        exclude group: 'httpclient'
    }

    compile 'com.squareup.retrofit:retrofit:1.9.0'
    compile 'com.squareup.okhttp:mockwebserver:2.3.0'
    compile 'de.hdodenhof:circleimageview:1.2.2'
    compile 'com.android.support:multidex:1.0.1'
    compile 'com.google.android.gms:play-services-maps:7.5.0'
    compile files('libs/bitlyj-2.0.0.jar')

}

Also getting this error when project is built,

Caused by: java.lang.NoClassDefFoundError: com.package.R$styleable
            at com.package.widgets.StyleableTextView.<init>(StyleableTextView.java:23)

This is StyleableTextView class,

public class StyleableTextView extends TextView {

    public StyleableTextView(Context context) {
        super(context);
    }

    public StyleableTextView(Context context, AttributeSet attrs) {
        super(context.getApplicationContext(), attrs);
        UiUtil.setCustomFont(StyleableTextView.this, context, attrs,
                R.styleable.com_eywa_wonk_widgets_StyleableTextView,
                R.styleable.com_eywa_wonk_widgets_StyleableTextView_font);
    }

    public StyleableTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context.getApplicationContext(), attrs, defStyle);
        UiUtil.setCustomFont(StyleableTextView.this, context, attrs,
                R.styleable.com_eywa_wonk_widgets_StyleableTextView,
                R.styleable.com_eywa_wonk_widgets_StyleableTextView_font);
    }

}

This is the styleable in attrs,

<resources>

    <attr name="font" format="string" />

<declare-styleable name="com.package.widgets.StyleableTextView">
        <attr name="font" />

    </declare-styleable>

</resources>

Answer 1

When you are using multidex , then try to extend your application class with MultiDexAppication instead of Application and override below method this required for Android below 5.0 (because 5.0 and above support to the multidex)

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

and in dependencies add this

compile 'com.android.support:multidex:1.0.1'
