how to solve = Manifest merger failed : Apps targeting Android 12 and higher are required to specify an explicit value for `android:exported`?

After upgrading to Android Studio Dolphin | 2021.3.1, the application is not compiling. It shows
Apps targeting Android 12 and higher are required to specify an explicit value for android:exported when the corresponding component has an intent filter defined
I have set all the activity with android:exported="false". But it is still showing this issue.

OPTION 1
You need to set android:exported to either true or false in your AndroidManifest.xml.(which you have done)
OPTION 2
Downgrade your project to an older SDK version, then rebuild project.
After a successful build, open your project's AndroidManifest.xml.
Click on the Merged Manifest tab at the bottom of the file and search for any <activity> that includes an <intent-filter> tag and is missing the android:exported attribute
To confirm that these activities are the issue, add them directly to your project's AndroidManifest.xml file with the missing android:exported attribute added and try rebuilding the project.
If <activity android:name="com.example.MainActivity"> is missing the android:exported attribute, add it to your AndroidManifest.xml file.
OPTION 3
You are using a library that doesn't target Android 12 yet. You can either upgrade the version if there is or remove it.
Good luck!

if you are using other packages or libraries, some of these libraries may not have set android:exported=”false” or android:exported=”true” in their Manifest files.
If you do not want to update those packages to the latest, we will have to over-ride their manifest files in the app's Manifest file.
So Step 1 is to find which package/libraries manifest files are missing the android:exported=”false” or android:exported=”true” .
This is done by downgrading your targetSdkVersion to 30 so that it compiles correctly. When the app compiles correctly it will generate a mergedManifest file in
build/app/intermediates/merged_manifests/debug/AndroidManifest.xml and
build/app/intermediates/merged_manifest/debug/AndroidManifest.xml
Step2: After you find the services / packages missing the android:exported=”false” or android:exported=”true”, we will copy those activities directly to app/src/res/AndroidManifest.xml and add in android:exported=”false” or android:exported=”true”.

If you got this messages from your android studio, in your main activity add in android:exported=”false” or android:exported=”true” will solved this issue.

Flutter Android app not running setting compileSdkVersion and targetSdkVersion to SDK 31

When launching the app on a new Android device (SDK 31), the debugger is showing the following error message:

Error launching application on sdk gphone64 x86
Setting compileSdkVersion and targetSdkVersion to 30 do launch the app as it should.
Executing the app on older devices makes no issue at all.
The only issue is launching the app with compileSdkVersion and targetSdkVersion set to 31 on Android devices > SDK 30
What can I do?

IN the AndroidManifest.xml, every activity tag must have the android:exported="true" set.
Update:
<activity
android:name="com.yalantis.ucrop.UCropActivity"
android:screenOrientation="portrait"
android:theme="#style/Theme.AppCompat.Light.NoActionBar"/>
to
<activity
android:exported="true"

Adjust your android/app/build.gradle so that your app compiles against the latest Android SDK:
android {
compileSdkVersion 31
}
You don't need to adjust targetSdkVersion just yet.
usesPermissionFlags was added recently and some of your plugins may already support it.
https://developer.android.com/guide/topics/connectivity/bluetooth/permissions#assert-never-for-location has all the details.

check build.gradle in android/app
compileSdkVersion 30
minSdkVersion 16
targetSdkVersion 30
If this doesn't fix then probably you are missing a permission in android manifest in android/app/src/main/AndroidManifest.xml

The error message generally comes from AAPT2.
As one can see, this attribute exists since API level 17.
For debug purposes, the merged AndroidManifest.xml #line 34 would rather be interesting, because the question where android:usesPermissionFlags even comes from, still remains, since the AndroidManifest.xml within module :app doesn't have this line and the merged version needs to obtain it from somewhere - which can only be another one module or some AAR library.
buildToolsVersion "30.0.3" should work, but since nothing else had been declared, this still should be something alike ...nevertheless the version of Android Studio (archive) also plays a role (it needs to match the version of the Gradle plugin, which is 4.1.3, with Gradle 4.4)... or for the current "Arctic Fox", this would be 7.0.3, with Gradle 7.2 (you are building a legacy project).
aapt2 version should return:
Android Asset Packaging Tool (aapt) 2.19-6966805
And this would be the table with the versions to use.
There's actually also a small chance Gradle is too new.
And by the way... I can even proof that it WAS an assumption (besides the :clean task usually resides in the root build.gradle and not the module build.gradle, which is a potential issue):
task clean(type: Delete) {
delete rootProject.buildDir
}
This states, that ./build is being deleted, but not ./app/build. I'd even go further and not only delete ./build, but also ~/.gradle/cache.
And if there should be further Java/Kotlin modules present, make sure that not one of them is being built with an outdated buildToolsVersion.
When keeping it within the module build.gradle, it should remove them all:
task clean(type: Delete) {
delete rootProject.buildDir
delete project.buildDir
}

If you are upgrading your gradle build tools to a higher level then you also need to upgrade the wrapper to some stable version from the android/ gradle/wrapper/gradle-wrapper.properties. Example if you update tools to classpath 'com.android.tools.build:gradle:4.2.1' and the wrapper version to 6.8.1. then the app should build.
Your compile and targeted sdk's are absolutely fine. In case the flag issue persists add this into your manifest
<uses-permission
android:name="android.permission.BLUETOOTH_SCAN"
android:usesPermissionFlags="neverForLocation" />

what is the problem here ? I have tried to do exactly what the docs says , any help ?

Check your pubspec.yaml and find duplicates under dependencies.
for example : you may be use barcode scanner and image picker in the same project. barcod scanner has a image picker inside it. so a problem will be occured as this.

Try adding implementation 'com.google.guava:guava:28.2-android' to your bulid.gradle:app. refer this and this for more info.

If you're using androidX or jetifier you need to have the following in your projects android/gradle.properties
android.useAndroidX=true
android.enableJetifier=true

Solution
check your package basically this error is related your package.
barcode scanner and image picker using same class that creates Duplicate class
also device_info_plus, package_info_plus: ^3.0.2 and storage info plus.
check your packages
and run flutter clean and than pub get.
if not find which packages creating issue than compare pubspec.yaml packages with compiled packages in build.
if get this by upgrading kotlin version than add these line in app/buid.gradle file
dependencies {
constraints {
implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk7:1.8.0") {
because("kotlin-stdlib-jdk7 is now a part of kotlin-stdlib")
}
implementation("org.jetbrains.kotlin:kotlin-stdlib-jdk8:1.8.0") {
because("kotlin-stdlib-jdk8 is now a part of kotlin-stdlib")
}
}

Flutter + Android: How to remove firebase from project "E/FirebaseInstanceId: Failed to resolve target intent service"

I used Firebase in an old iteration of my flutter project, but I guess I either didn't remove it properly or it was there all the time. In any case, how do i get rid of Firebase and hence forth remove this error from my Android logs? I've grepped the entire project and cannot find 1 instance of firebase. I've removed it from my yaml file a while back and still this pops up.
FirebaseInstanceId: Failed to resolve target intent service, skipping
classname enforcement FirebaseInstanceId: Error while delivering the
message: ServiceIntent not found.
Here's my AndroidManifest.xml
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.eumag">
<!-- The INTERNET permission is required for development. Specifically,
flutter needs it to communicate with the running application
to allow setting breakpoints, to provide hot reload, etc.
-->
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />
<!-- io.flutter.app.FlutterApplication is an android.app.Application that
calls FlutterMain.startInitialization(this); in its onCreate method.
In most cases you can leave this as-is, but you if you want to provide
additional functionality it is fine to subclass or reimplement
FlutterApplication and put your custom class here.

Go to your pubscpec and remove all Firebase packages
Go to your Gradle files, root and app level and remove the Firebase references
Go to the root of Flutter project, delete the build folder
Go to your Android project remove it's build folder
Search for FirebaseInstanceId in your entire project (If you're using Visual studio code).
The Flutter Firebase package generates the FirebaseInstanceId and receiver when you build your project. Unless you added your own one, in that case. Just go and remove that file.
