Android Question Can't install package on Android version 8.0 and below

[prince_j325]

I made an app with Ads. Honestly this is my app developed in b4a. But I found out that the apps can be only install on android version 9 and up. Any fix for this?

This is my Manifest File

AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="28"/>
<supports-screens android:largeScreens="true"
    android:normalScreens="true"
    android:smallScreens="true"
    android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
CreateResourceFromFile(Macro, Themes.DarkTheme)
SetActivityAttribute(Main, android:screenOrientation, "portrait")
SetActivityAttribute(mdlGlobal, android:screenOrientation, "portrait")
SetActivityAttribute(mdlCountries, android:screenOrientation, "portrait")
SetActivityAttribute(mdlListCountries, android:screenOrientation, "portrait")
CreateResourceFromFile(Macro, FirebaseAnalytics.Firebase)
CreateResourceFromFile(Macro, FirebaseAdMob.FirebaseAds)
CreateResourceFromFile(Macro, FirebaseAnalytics.GooglePlayBase)
AddReplacement($ADMOB_APP_ID$, ca-app-pub-7449308286288394~xxxxxxxxxx)

This is my code on Main Activity

Activity.LoadLayout("lyMain")
   

    BannerAd.Initialize2("BannerAd", "ca-app-pub-7449308286288394/xxxxxxxxxx", BannerAd.SIZE_SMART_BANNER)
    Dim height As Int
    If GetDeviceLayoutValues.ApproximateScreenSize < 6 Then
        'phones
        If 100%x > 100%y Then height = 32dip Else height = 50dip
    Else
        'tablets
        height = 90dip
    End If
   
    Activity.AddView(BannerAd, 0dip, 45dip, 100%x, height)
    BannerAd.LoadAd
   
    IAd.Initialize("iad", "ca-app-pub-7449308286288394/xxxxxxxxxx")
    IAd.LoadAd

Don't post all of your keys.

You haven't told us what happens when you try to install it on an Android 8 device.

Something unexpected happened. Check the app icon and make sure that it is not too large.

Also check the unfiltered logs and see why the installer crashed.

Thanks Erel,btw what is the recommended icon size?

 

[Erel]

Did it solve the problem?

So it is not the place to ask this question.

Thanks Erel! your right it's the icon size. I change the resolution size to 70 and the dimension size. The one who designed the icon made it large..
God Bless You
