Android Question [SOLVED] Alternative to check if WhatsApp is installed without using PackageManager - QUERY_ALL_PACKAGES on + SDK30

scsjc · Nov 8, 2021

Until now I used PackageManager to check which applications were installed (for example WhatsApp)

Currently google requires QUERY_ALL_PACKAGES in Manifest in order to have a list of Installed Packages.

Is it possible to know if WhatsApp is installed, via tried through some kind of Try-Catch error?

B4X:

Sub APKinstalada(packagename As String) As Boolean
    Try
        Dim PM As PackageManager   
        Dim ApplicationLabel As String = PM.GetApplicationLabel(packagename)
        log("Installed: " & ApplicationLabel)
        Return True
    Catch
        log("Not Installed: " & packagename)
        Return False
    End Try
End Sub

B4X:

 Dim pm As PackageManager
    Dim in As Intent
    in = pm.GetApplicationIntent("com.somewhat.package")
    If in.IsInitialized Then
        ' Package is installed
    End If

I find solution, add manifest:

B4X:

AddManifestText(<uses-permission android:name="android.permission.QUERY_ALL_PACKAGES"/>)

Also read this if you want to upload your app on Play Store.

I don't know if this will help but this is how I try to open Edge

B4X:

        If ext = ".htm" Or ext = ".html" Then
            ' Provider needs manifest AddApplicationText entry for FileProvider
            ' Provider needs manifest CreateResource entry for File.DirRootExternal
            Provider.SharedFolder = File.DirRootExternal
            helpintent.Initialize(helpintent.ACTION_VIEW, Provider.GetFileUri(helpfile))
            helpintent.SetType("text/html")
            helpintent.Flags = 1 'FLAG_GRANT_READ_URI_PERMISSION
            helpintent.SetPackage("com.microsoft.emmx")
            Try
                StartActivity(helpintent)
            Catch
                MsgboxAsync("An installation of Microsoft Edge is required to read this help file.", "Microsoft Edge")
            End Try
            Return

            End Try
            Return

I had already thought about launching directly and sharing to whatsapp, and that TryCatch would check if it works, and if not give an error

But I would like to be able to show the WhatsApp button if it is installed, and if it is not installed hide the button. (Same for WhatsAppBussines)

No need to add QUERY_ALL, just add the com.whatsapp to your manifest:


<queries>
        <!-- Explicit apps you know in advance about: -->
        <package android:name="com.whatsapp"/>
        <package android:name="com.whatsapp.w4b"/>
    </queries>

Check if application is installed - Android

I'm trying to install apps from Google Play. I can understand that on opening the Google Play store URL, it opens the Google Play and when I press the back button, the activity resumes. Intent
