Android auto manifest merger failed: attribute is also present at

I'm currently trying to build a hello world app as my first android auto app. Earlier, when I was trying to run the app it was giving me some minSdk error and I managed to fix that. Now, when I try to run it, it gives me this error:
Manifest merger failed : Attribute meta-data#androidx.car.app.CarAppMetadataHolderService.CAR_HARDWARE_MANAGER#value value=(androidx.car.app.hardware.ProjectedCarHardwareManager) from [androidx.car.app:app-projected:1.1.0] AndroidManifest.xml:34:17-86
is also present at [androidx.car.app:app-automotive:1.1.0] AndroidManifest.xml:44:17-87 value=(androidx.car.app.hardware.AutomotiveCarHardwareManager).
Suggestion: add 'tools:replace="android:value"' to <meta-data> element at AndroidManifest.xml to override.
I've been trying to follow the instructions here on how to edit the manifest file and everything looks fine according to the instructions.
Here's the AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"

testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}

Since you are targeting Android Automotive in your manifest, you can get rid of the following dependency in your gradle file:
implementation("androidx.car.app:app-projected:1.1.0")
That should fix the conflict you are having.

Andrdoid studio emulator doesn't support google maps

Hi all I'm making an app that will use google maps api but my emulator keeps saying that google maps is not supported by my device even though my emulator is a google pixel which means it should support google maps.
I added my API key to the local.properties file
`
sdk.dir=C\:\\Users\\User\\AppData\\Local\\Android\\Sdk
MAPS_API_KEY=API_KEY
`
And added the following code to the dependencies element in my project level build.gradle
uildscript{
dependencies {
classpath"com.google.android.libraries.mapsplatform.secrets-gradle-plugin:secrets-gradle-plugin:2.0.0"
}
}
plugins {
id 'com.android.application' version '7.1.1' apply false
id 'com.android.library' version '7.1.1' apply false
id 'com.google.android.libraries.mapsplatform.secrets-gradle-plugin' version '2.0.0' apply false
}
task clean(type: Delete) {
delete rootProject.buildDir
}
And the specified code in android docs is present in my module level build.gradle file under plugins
plugins {
id 'com.android.application'
id 'com.google.android.libraries.mapsplatform.secrets-gradle-plugin'
}
android {
compileSdk 32
defaultConfig {
applicationId "org.me.gcu.labstuff.androidcwk"
minSdk 23
targetSdk 32
versionCode 1
versionName "1.0"
testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
buildFeatures {
viewBinding true
}
}
dependencies {
implementation 'androidx.appcompat:appcompat:1.4.1'
implementation 'com.google.android.material:material:1.5.0'
implementation 'com.google.android.gms:play-services-maps:17.0.1'
implementation 'androidx.constraintlayout:constraintlayout:2.1.3'
testImplementation 'junit:junit:4.13.2'
androidTestImplementation 'androidx.test.ext:junit:1.1.3'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.4.0'
}
and updated my android:value attribute as follows in AndroidManifest.xml
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.me.gcu.labstuff.androidcwk">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/Theme.Androidcwk">
<!--
TODO: Before you run your application, you need a Google Maps API key.
To get one, follow the directions here:
https://developers.google.com/maps/documentation/android-sdk/get-api-key
Once you have your API key (it starts with "AIza"), define a new property in your
project's local.properties file (e.g. MAPS_API_KEY=Aiza...), and replace the
"YOUR_API_KEY" string in this file with "${MAPS_API_KEY}".
-->
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="${MAPS_API_KEY}" />
<activity
android:name=".MapsActivity"
android:exported="true"
android:label="#string/title_activity_maps">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
and still my emulator says google maps is not supported. Any help would be extremely appreciated thanks.

AndroidManifest.xml "Unresolved package" Error

I am developing a Media Player app. I was implementing MediaButtonReceiver (which is used to control Media inputs given from Headphone, bluetooth like external devices).
But while declaring receiver in the manifest file I encountered a number of errors.
Errors:
Unresolved package session
Unresolved class MediaButtonReceiver
Class referenced in the manifest, com.example.android.MediaPlaybackService, was not found in the project or the libraries
Unresolved package android
Unresolved class MediaPlaybackService

</manifest>

"Unresolved package/reference" means that the supporting library doesn't exist. According to the bewildering Android dev doc, you must download it by adding the following code to Gradle Scripts > build.gradle (Module: xxx.app) inside dependencies{}, resync and the error will disappear from androidx.media.session.MediaButtonReceiver
implementation("androidx.media:media:1.6.0")
and add this code for the error to disappear from android.support.v4.media.session.MediaButtonReceiver
implementation("com.android.support:support-media-compat:28.0.0")
Check latest version of androidx and v4

Maybe try to declare it in AndroidManifest.xml like the documentation said (for AndroidX) :
<receiver android:name="androidx.media.session.MediaButtonReceiver" >
<intent-filter>
<action android:name="android.intent.action.MEDIA_BUTTON" />
</intent-filter>
</receiver>

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'.
> java.io.IOException: Can't write [G:\work\myapp\app\build\intermediates\multi-dex\debug\componentClasses.jar]

</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!!!

Many errors after trying to set facebook-sdk in android studio

I have 2 issues. First, I added the facebook sdk, and after that, many errors appeared.
The same but repetitive errors in my java 'main file' is 'cannot resolve symbol' in the R and all others.
second issue, the following error:
"diamond operator is not supported in -source 1.6" , "Execution failed for task ':facebook:compileReleaseJava'. > compilation failed; see the compiler error output for details."
(and that's after doing everything just like in the tutorials)
thanks in advance! I'm stuck in this like for about 3 weeks and almost everyday I tried solving but I still can't figure out a way.

thanks

You can simplify the use of the library by calling
compile 'com.facebook.android:facebook-android-sdk:4.0.0'
in your build.gradle file

1)Include in your apps settings.gradle
like this:
include ':facebookSDKVersion_3141'
2)You have to compile your facebook sdk in your apps build.gradle
do like this:
dependencies {
compile project(':facebookSDKVersion_3141')
}
Clean the project and build the project again should work.
or
There is an easier way ,click on file on android studio
select New Module->Import Existing Project->Browse the location of your sdk
and this should work
