Android studio 3.0 error with sweet-alert-dialog library

Add this library to app/build.gradle:

dependencies {
    ...
    implementation 'com.github.f0ris.sweetalert:library:1.5.1'
}

Usage:

SweetAlertDialog pDialog = new SweetAlertDialog(this, SweetAlertDialog.PROGRESS_TYPE);
pDialog.getProgressHelper().setBarColor(Color.parseColor("#A5DC86"));
pDialog.setTitleText("Loading");
pDialog.setCancelable(false);
pDialog.show();

for more usages about progress read THIS.

use this library is the same just with new features https://jitpack.io/p/Leogiroux/sweet-alert-dialog

I got the solution!

if you are using implementation 'cn.pedant.sweetalert:library:1.3' library, just add the below line in your proguard-rules.pro file.

-keep class cn.pedant.** { *; }
