The error seems to be generated because of proguard file

Here is the proguard-rules.pro as follows -

# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in /home/adisoft2/android/android-sdk-linux/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html
# Add any project specific keep options here:
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
