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: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.

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"

consumerProguardFiles "consumer-rules.pro"
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}

}
}

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.

Why can't I debug my Android project over the phone?

I'm just getting into the field of Android development and I need to run my project for the first time in order to continue my learning process.
Unfortunately my computer is'nt powerful enough to run an AVD and every time I try to debug it with my phone I get this error message:
A problem was found with the configuration of task ':app:processDebugManifest'
(type' ProcessMultiApkApplicationManifest').
File 'E:\android\app\build\intermediates\merged_manifest\debug\out\AndroidManifest.xml' specified for
property 'mainMergedManifest' does not exist.
General Information:
I'm trying to debug a brand new project using my Galaxy A 70 (running Android 10). If necessary I would be happy to provide any additional information (to the best of my ability) regarding the project, the specifications of my phone or computer, etc.
build.gradle of app module:

}
android {
compileSdkVersion 29
defaultConfig {
applicationId "com.example.myapplication"

android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"

<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
I would be very grateful for any help regarding this problem.
Thanks in advance

You need a debug build type that is set to debuggable true
Add this to your buildTypes in build.gradel
buildTypes {
debug {
debuggable true
}
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
}
}
Then run gradle sync. , and in the build variants select the debug configuration, and then you'll be able to debug your app

APK Parsing Error

I do not know how to continue...
I build a signed or unsigned apk with Android Studio (everything is up to date). Now I want to test this apk and install it on my phone.
But I always get a parsing error...
I tried diffrent devices but with the same result. I tryed a blank app but with the same result. I can't install it because of a parsing error. But deploying directly from AS works just fine!
What I tried out:
Reinstalling SDK (latest)
Reinstalling Android Studio (latest)
Reinstalling Java (latest)
an older gradle version (2.2.3)
Dev options and allowing unknown sources are aktive on all my devices.
minSdkVersion is set to 19 (I just have devices with Android 5 and 6)
I don't have an idea where the problem comes from...
Can somebody help me?
Thanks in advance!!!

OK I finally solved my problem!
I uploaded the apk to dropbox! That was the problem!
If I move the apk directly to the download folder of my device (using USB) everything works fine!
But anyway thanks for your help!

It's not the code at all! I tried a new blank project and I couldn't install it too
but here is the Manifest and the gradle:

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.

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
