Android plugin in Unity

i am trying to add a local .aar from an android library in Unity. Currently it is a very basic project, in unity there is just one script that opens the activity from android library on a button click.
I manually added the .aar in the /plugins/android folder (I am using 2019.4 version), and on build I keep getting the error that a resource is not found (Theme.AppCompat.Light.NoActionBar' not found in AndroidManifest)
.
This are my graddle config & AndroidManifest:
plugins {
id 'com.android.library'
}
android {
compileSdk 31
defaultConfig {
minSdk 21
targetSdk 31
versionCode 1
versionName "1.0"

</manifest>
I am a newbie when it comes to mobile development, but I think the issue is that the dependencies from build.graddle are not included in the .aar.
I think my options are to either create a fat .aar , manually download dependencies .aar's or to publish .aar to a central repository. Am I on the right track?
Any help is more than appriciated

I manage to get over the error by adding a custom graddle template to the unity project.

Android Studio Sync fails due "failure to parse XML in AndroidManifest.xml"

I decided to update an old app, sadly when I try to sync the project I'm getting the following Gradle Sync error:
"ERROR: Failed to parse XML in C:...\app\src\main\AndroidManifest.xml
ParseError at [row,col]:[17,9]
Message: expected start or end tag
Affected Modules: app"
After doing my research and forums, the problem seems to be in the AndroidManifest (duh!) when I go to the line 17 I find the Meta-data of my app, and if I add some lines before this, the error moves accordingly to the line.
I have also updated the Gradle to 4.10.1, the Android Plugin version is 3.3.1; and I'm using the "Default Gradle Wrapper"

I'll appreciate if someone could point me in the right direction as I seem to be missing some tags in my manifest and at this point I don;t know what I'm doing wrong here :(
Thank you all before hand for your help! :)

Remove below line from your manifest.xml file
///META DATA
And replace it with below comments syntax
<!—- META DATA —->

As pointed out here already to comment in XML we shouldn't be using /// but <!-- > instead.
Please replace /// META DATA with <!-- META DATA-> and that should work.

If you want to make comment in xml file, you need to use <!--your comment here--> this tag. // or /**/ doesn't work

I also faced the same issue, where removing the comments from
//this is a comment
to
<!--this is a comment-->
worked for me.

Android - Set up Google Play Services and Firebase - Gradle build error

I'm having issues including Google services in my project.
The errors
Following these instructions, and also referring to the docs to set it up, I encounter a problem with the apply plugins property:
For reasons unbeknownst to me, it's not fetching correctly (something about the version being wrong) even though that property is auto-filled when you click on 'Add FCM to your app' (in purple). And as you can see, it doesn't have any version numbers in the URL.
I also encounter a problem with the implementation 'com.google.firebase:firebase-messaging:17.1.0' property.
I'll add in my manifest and gradle files for reference:

Full error message
Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 15.0.1.
And then a giant list of errors:

Change this:
classpath 'com.google.gms:google-services:3.1.1'
into this:
classpath 'com.google.gms:google-services:4.0.2'
to prevent from getting the version conflict error.
Check here for more info:
https://android-developers.googleblog.com/2018/05/announcing-new-sdk-versioning.html
Beginning with version 15 of all Play services and Firebase libraries, each Maven dependency matching com.google.android.gms:play-services-* and com.google.firebase:firebase-* is no longer required to have the same version number in order to work correctly at build time and at run time.
In order to support this change in versioning, the Play services Gradle plugin has been updated to 3.0.0(which is the first version).

Android application on Gradle: Unable to merge dex

I have an error with my app in Android studio:
Execution failed for task
':app:transformDexArchiveWithExternalLibsDexMergerForDebug'.
> com.android.builder.dexing.DexArchiveMergerException: Unable to merge dex
I use Gradle and Kotlin.
Android Studio 3.0.1.
Windows 10 Pro 64.
I have research this theme on SO and I have tried some solution from here, like that:
Clean and rebuild project. No changes.
Change 'compile' in gradle to 'implementation'. No changes.
Delete .gradle and build directories. No changes.
Add multiDexEnabled true in defaultConfig in gradle. In this case, I have another error:
Execution failed for task ':app:transformClassesWithMultidexlistForDebug'.

</application>
What am I missing?
UPD
It seems I found out the point after that the problem has appeared. It was after adding Twilio configuration. I used this manual: Twilio and Android
This is all changes that have been done:
Add to build.gradle:
implementation 'com.twilio:client-android:1.2.21'
Add to AndroidManifest:
<service android:name="com.twilio.client.TwilioClientService"
android:exported="false" android:stopWithTask="true"/>
Add to proguard-rules.pro
# Twilio Client
-keep class com.twilio.** { *; }
# Apache HttpClient
-dontwarn org.apache.http.**
That's all. Before this changes I didn't have this error

Use this in your build.gradle in app Module if you want to read an .aar file
for your libs dir:
repositories{
flatDir{
dirs 'libs'
}
}
dependencies {
compile(name:'nameOfYourAARFileWithoutExtension', ext:'aar')
}
But it seems that your problem is multidex(means that you have more than 65K methods in your project so use this:
android {
defaultConfig {
multiDexEnabled true
}
}
and if your minSdk < 20 then use this as well:
compile 'com.android.support:multidex:1.0.1'
Hope it helps!!!

Android Studio Error: Execution failed for task ':app:processDebugManifest'

I am completely new to Android Studio so it may sound a silly thing to an experienced person.
I am getting an error in Android Studio which states:
Error:Execution failed for task ':app:processDebugManifest'.
> Manifest merger failed : Attribute meta-data#android.support.VERSION#value
value=(25.3.1) from [com.android.support:design:25.3.1]
AndroidManifest.xml:27:9-31
is also present at [com.android.support:appcompat-v7:26.0.0-alpha1]
AndroidManifest.xml:27:9-38 value=(26.0.0-alpha1).
Suggestion: add 'tools:replace="android:value"' to <meta-data> element at
AndroidManifest.xml:25:5-27:34 to override.
I have Googled this and tried looking into it to solve it on my own, however, similar issues that I have found aren't quite the same errors.
I'm not experienced enough to understand and generate a fix for it although I understand some of it.
It may be the case that I need to provide more information for this so please let me know if so.

SECOND EDIT:
Following the answer by Arefeh and the comment by Kunal, I changed the version mismatch by replacing compile 'com.android.support:design:25.3.1' with compile 'com.android.support:design:26.0.0-beta2'.
For this to work, I had to add maven { url "https://maven.google.com" } in the build.gradle (Project: appname) file within allprojects{} (have updated above to illustrate this).
Now I keep getting a render error which says failed to instantiate one or more classes. The classes are different for each activity depending on what I've used in the activity e.g.
The following classes could not be instantiated:
- android.support.v7.widget.AppCompatImageView
...
...

I guess the problem is for difference between versions of support libraries. Change your version of design library to 26 or higher.
compile 'com.android.support:design:26.+'

What seems to have worked in this instance, is going to File > Project Structure then in app > Properties where it says Compile Sdk Version and Build Tools Version, I changed them to API 25: Android 7.1.1 (Nougat) and 25.0.3 respectively. After which I synced the project and gradle and then rebuilt.
I then repeated the process and changed back again to API 26: Android 8.0 (O) and 26.0.0. So far it is working again although I will update if this changes.
