I'm unable to create the release APK as a result of these errors. But I'm able to test my app and also create the debug APK successfully. I then tried to create the release APK of the OLD version of my code which worked without any issues back then, but I'm still getting the same errors.
Here's my build.gradle (app) file:
apply plugin: 'com.android.application'
android {
compileSdkVersion 28
defaultConfig {
applicationId "com.cg.lrceditor"
minSdkVersion 21
targetSdkVersion 28
versionCode 24
versionName "2.2.3"
testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
vectorDrawables.useSupportLibrary = true
}
buildTypes {
release {
shrinkResources true
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
debug {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
productFlavors {
}
}
dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')
implementation 'com.android.support:appcompat-v7:28.0.0'
implementation 'com.android.support:design:28.0.0'
implementation 'com.android.billingclient:billing:1.1'
testImplementation 'junit:junit:4.12'
implementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'org.testng:testng:6.9.6'
}
Not sure why, but if I set both minifyEnabled and shrinkResources to false, I am able to create the release APK successfully. But then the app size won't be optimized.
I've tried ignoring the warnings using -dontwarn org.xmlpull.v1.** or -ignorewarnings in proguard-rules.pro and I'm able to generate the release APK, but then when I launch the app, it crashes. Here's the relevant stack trace of the crash:

How do I fix these issues with minifyEnabled and shrinkResources on?
library class android.content.res.XmlResourceParser extends or implements program class org.xmlpull.v1.XmlPullParser
library class android.content.Intent depends on program class org.xmlpull.v1.XmlPullParser
library class android.content.IntentFilter depends on program class org.xmlpull.v1.XmlSerializer
As mention in the first error there is some problem with package org.xmlpull.v1
so just ignore them from the proguard . Add this rule to your proguard
-keep class org.xmlpull.v1.** { *; }
