AndroidError : Program type already present : android_serialport_api.SerialPort when I try generate Signed APK from Android Studio

I am getting specified exception after adding .aar file to app gradle:Program type already present: android_serialport_api.SerialPort

Debug apk is working fine but when I try to build signed APK giving above exception.
Please help me on this.Thanks in advance.

The issue is that you have more that one package using android_serialport_api.SerialPort.
There is 2 ways of dealing with this. The first is going through each library and checking if it's using it or you can find duplicates by running:
gradlew -q dependencies yourProject:dependencies --configuration implementation
You can also exclude it from your merchantsdk, like this:
implementation(name: 'merchantsdk', ext: 'aar'){
exclude module: 'SerialPort'
}

How to Avoid Conflict in Android Gradle Dependencies

I am new in android and working on an old Android project. It has a Google Places Autocomplete feature which is not working currently as Place SDK for Android it used is deprecated currently. without this everything is working fine but when i am trying to add this places sdk implementation 'com.google.android.libraries.places:places:1.0.0' for auto complete place feature then gradle sync successfully but when try to run the app then it shows error on all xml files as resource linking fails or duplicate value for resource 'attr/font' with config ' etc etc. My question how I can use this sdk without disturbing others. Below is my App level Gradle file

Migrate your project to Android X which is the best solution to prevent the dependency conflict

ClassNotFoundException: unable to find class "android.support.v4.util.ArrayMap"

The signed apk of my app runs on the android versions higher than 5.0.1 but I am facing this issue that my app crashes immediately after launching the app on version 5.0.1 and this is the error I get -
Caused by: java.lang.ClassNotFoundException: Didn't find class "android.support.v4.util.ArrayMap" on path: DexPathList[[zip file "/data/app/com.*****1/base.apk"],nativeLibraryDirectories=[/vendor/lib, /system/lib]]
please note that the app is not crashing when I run using android studio but it crashes when I run the signed apk.
I don't know what to do, I have gone through a lot of stackoverflow questions but found nothing that can solve my issue. This is my app.gradle file -

If the gradle version is 3.x.x try to add maven { url 'https://maven.google.com' } to
allprojects {
repositories {
//add here
}
}
instead of google() and sync gradle. It should help. You can see difference between them using this link.

I found the solution. I tried building the Signed apk for both the signature versions V1(jar signature) and V2(full apk signature) and it worked.

Could not find any version that matches com.google.android.gms:play-services:[15.0.0, 16.0.0)

i use firebase and onesignal , but when opening project give me the error ,
i update build-tools , sdk tools and google play services.

Try adding maven { url "https://maven.google.com" } to your root level build.gradle file like this:
allprojects {
repositories {
jcenter()
maven {

}
}
}
You can also do it like this if your version of Gradle plugin supports it:
allprojects {
repositories {
google()
jcenter()
}
}

(I'm also leaving this duplicate answer text here for now - although it will probably eventually be deleted - to preserve the solution that the original poster marked as correct.)
Apparently, jcenter has started mirroring Google's repo. Try moving google() before jcenter() in the allprojects section of your project's build.gradle (like this):
repositories {
google()
jcenter()
maven { url "https://maven.google.com" }
maven { url "https://jitpack.io" }
maven { url "https://adcolony.bintray.com/AdColony" }
maven { url "https://dl.bintray.com/ironsource-mobile/android-sdk" }
}

Try another version of this APIs. And you should to declare constant version and use it like {$const} then your gradle will be less error prone about versions difference.
