Here is my proguard-text file

 # To enable ProGuard in your project, edit project.properties # to define the proguard.config property as described in that file. # # Add project specific ProGuard rules here. # By default, the flags in this file are appended to flags specified # in ${sdk.dir}/tools/proguard/proguard-android.txt # You can edit the include path and order by changing the ProGuard # include property in project.properties. # # For more details, see # http://developer.android.com/guide/developing/tools/proguard.html # Add any project specific keep options here: -dontskipnonpubliclibraryclassmembers # 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 { # public *; #}

try adding these lines first in our proguard.cfg file in your project, as shown below:

 -ignorewarnings

if you have annotation in your project, please add the following line below

 -keepattributes *Annotation*

and make sure your gradle file has minifyEnabled as false
