Sgtep 2- Using Dependent JAR

apply plugin: 'com.android.application'

android {
compileSdkVersion 23
buildToolsVersion "23.0.2"

defaultConfig {
applicationId "com.scrum.siddhu.scrumapplication"
minSdkVersion 8
targetSdkVersion 23
versionCode 1
versionName "1.0"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
}

dependencies {
compile fileTree(include: ['*.jar'], dir: 'libs')
testCompile 'junit:junit:4.12'
compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'
compile files('libs/ksoap2-android-assembly-2.5.8-jar-with-dependencies.jar')
}

Step 3- settings.gradle

include ':app', ':ksoap2-android-assembly-2.5.8-jar-with-dependencies'

Step 4- activity_main.xml

android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">

android:id="@+id/toolbar"
android:layout_width="match_parent"

android:background="?attr/colorPrimary"
app:popupTheme="@style/AppTheme.PopupOverlay" />

android:id="@+id/fab"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="bottom|end"
android:layout_margin="@dimen/fab_margin"
android:src="@android:drawable/ic_dialog_email" />

Step 5- AndroidManifest.xml

package="com.scrum.siddhu.scrumapplication">

android:allowBackup="true"
android:icon="@drawable/scrum"
android:label="@string/app_name"
android:supportsRtl="true"
