'android:exported' property not set error despite having it set in android manifest

This is the error i get when i try to submit app to play store.
"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. See: developer.android.com/about/versions/12/behavior-changes-12#exported"
This is my androidmanifest.xml file, i had set android:exported to true each time, but still its throwing this error, could someone please check and see what can be done to eliminate this error, here is my manifest file:

Please Note: I had set the package name to xxx.xxx. When i had submitted it to play store i submitted it with correct name.

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)
UPDATE, added AndroidManifest.xml:

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

Android Error: Default Activity not found

I have a launcher activity but android studio says "Default activity not found". This started after I added a login activity which I wanted it to be the launcher activity (meant for when the user signs up only). So I would like the Main activity to be the launcher activity once the user installs my app and provide their credentials. Your help is much appreciated.
This is my manifest with both my login and main activities.

N.B The main activity extends my MapActivity, which extends FragmentActivity. It is starnge but I found this in logcat. I haven't implemented iheartradio library or anything. "Caused by: java.lang.ClassNotFoundException: com.clearchannel.iheartradio.alarm.LiveDeltaUpdateService"

You have a typo. <activity>, not <Activity>

A full AndroidManifest must contain the tag and the inside it.
You must declare the Activity with its fully qualified class name, and the package declaration can be ommited with a dot (.) if the Activity is inside the package of the application (declared at manifest.package attribute)
Such:

PS: You MUST read the stack trace generated from the error while running the application, you can use the logcat window at Eclipse or Android Studio or the Android Device Monitor included in the Android SDK installation.

You can try this:
File->Invalidate Caches->Restart

Simply deleting the .gradle folder in C://Users/username did it for me. Invalidating caches etc didn't.

Google Play Store - Find out why a device is incompatible

I published an android app in google playstore. Some clients complain about not being able to download the app as the play stores says it is "not compatible".
In google developer console, I can only see THAT a device is not supported. I want to know WHY a device is incompatible but that information is hidden from me.
Google has to have this information to determine compatibility, why is there no way to show this information to developers? Or am I wrong?
We'd really appreciate that feature, it is vital I think.
One device that fails, is for example: medion lifetab e10315
