You uploaded an Android App Bundle without 'android:exported' property set

I've built and Android App Bundle via Unity using target API level as 32. When I try to upload the .aab file to Google Play, I'm getting this error message:
"You uploaded an APK or Android App Bundle which has an activity, activity alias, service or broadcast receiver with intent filter, but without 'android:exported' property set. This file can't be installed on Android 12 or higher."
I can successfully upload .aab files I've created with API level 30, but I want to fully support Android 12 devices. When I try to build with API level 31 or 32, I get this error. I've already added android-exported tag to all activities, and I'm not sure why I keep getting this error. Minimum API Level is set to 21 (setting it to 23 also didn't work).
I'm using Unity 2020.3.30 (also was getting same error when building with Unity 2019.4.12). Also tried to export project and build .aab via Android Studio 4.4.1, but still no luck.
My Android.Manifest file is set as follows:

I've tried methods from answers and comments at other similar questions in StackOverflow, but none of them worked.

default robot icon instead of app icon after installation

I made my android app but when I install it on Anroid 6 my app has default robot icon instead my original app icon. But when I install the same app on device with android 4.4.2, my app icon is ok.
Any idea please what could be wrong? (I have already tried to remove app icon from android 6 desktop and make new shortcut but installed app in app list has the same robot icon)

You need to set the activity icon
<activity
android:icon="#drawable/ic_launcher"
android:name="com.example.myapp.menu.MenuActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>

Did you place your custom icon in the drawable-xxhdpi folder too?
if no then place it ,clean and reinstall ur app

set icon to #mipmap/ic_launcher, not to #drawable/ic_launcher

Had similar issue.
Solution was to
Remove background from ic_launcher.xml
In my case it was empty anyway but caused this error

App showing incompatible with the device I developed it on in play store

The reason given by a play support agent is :
"I've also found your app is not compatible with the Micromax Yurenka S due to a conflict in your app's manifest with the following:
No supported native platform:arm64-v8a, armeabi, armeabi-v7a"
I am pasting my manifest file below:
Can someone just point me what I am doing wrong.

Atlast found the issue after spending 2 days. Check the post for more details. I am posting the answer for someone who might come in future. Android app is supported by 0 devices
Check your build.gradle file - if you see something like:
compile 'org.apache.directory.studio:org.apache.commons.codec:1.+'
change it to:
compile 'commons-codec:commons-codec:1.+'

Cannot install application in Android Tablet

I am using Android Studio to develop an app which used Camera2 API. I can run the app in Google Nexus 9, however the app is not installed in the device and I cannot access it once I close the app. What am I doing wrong ?

While running my app, I thought I had the same problem.
The problem in my app was the app_name in the strings file was different that what I thought it is. So Basically I was looking for app "X" while the name i gave is "Y".
Maybe you have the same problem.

Android phones below a certain api level cannot see the play store listing

I have hosted my app on the Google Play Store. Most phones can go to the store and download it successfully. Certain phones can not see the listing, these phones are running Android 2.3.6.
I've a feeling that the target api in the manifest may have something to do with it?
This is what i have in my manifest.
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="11" />
.
All the phones on 4.x are fine.
Why can't lower Android phones see the listing?
Thanks.

NFC was added in API Level 10. More importantly, few API Level 10 and below devices have NFC hardware. You are requiring that devices have NFC hardware; ergo, you will not have very many API Level 10 and below devices that support your app.
If you do not absolutely need NFC to function, use android:required="false", and check for NFC availability at runtime, either via PackageManager and hasSystemFeature(), or just whether you can get your NfcAdapter.
In addition:
You will only be available for devices that have Maps V1, and I would imagine that some newer devices will start dropping support for that, since Maps V1 has been deprecated for a year.
You are wasting CPU and memory with those :remote receivers
