Getting error after updating android studio to 3.2

We are facing an error of default activity is not found after update android studio to version "3.2". On another PC, which is running lower version 3.1.4 of android studio, this same application is working. If anyone has a solution then please suggest us.
I have attached manifest file of screen shot of android studio for that error.

Android icon missing when uploading to playstore

When I install my application it's working fine, the icon is displayed and have no issues, however when installing the application on the device from the apk it does not show the application name, it shows the package with no icon, when uploading to playstore it gives me an error stating I should add an icon to the application.
This use to work until recently.
ic_launcher icon file does exist.

I found the problem:
<application
android:name="android.support.multidex.MultiDexApplication">
I removed the > after MultiDexApplication. Figured the android:icon was greyed out and hence not working.
Thanks.

I am not great at programming, so any tips would be extremely appreciated and helpful. The main problem is that android studio matches and other cases like that.

you use inline close tag and outline also just remove the (/) from the reciever tag, to be:
<reciever android:name="de.dfki.nocrastination.logging.BootCompleteReceiver" android:enabled="true" android:exported="false"> ==> removed "/"
<intent-filter>
<action android:name="android.intent.action.BOOT_COMPLETED" />
</intent-filter>
</reciever>
And add "/" to the last line to be

Build Failed, Missing Key Attribute (Android SDK)

I recently imported my project over from Eclipse ADT over to Android SDK. I'm trying to re-run my simulator but I am encountering a problem with my AndroidManifest.xml file which states: /Users/####/Documents/android/medicine/src/main/AndroidManifest.xml:13:13-30 Error: Missing one of the key attributes 'action#name,category#name' on element intent-filter at AndroidManifest.xml:13:13-30
I searched on Google for the error but haven't come up with anything solid. Is there a reason for this error, I am assuming it is because of the Android version? Any help on this would be great.
Below is my AndroidManifest.xml file:

check your these lines :
<activity android:label="#string/app_name" android:name="org.pgsqlite.SQLitePlugin">
<intent-filter />

here you define intent filter but not any action so if you don't want to specify any action there just delete it or add any action that you want to listen,

Android Google Maps V2 Blank Screen

With Android 4.0.4 Google Maps API V2 shows nothing (blank white screen). It works with Android >4.1, so the API key is correctly configured.
There are some Warnings in Logcat, but they also occur on Android >4.1, where everything works fine.
