Android Question [solved]How to retrieve multiple images via ACTION_SEND_MULTIPLE

KMatle · Apr 7, 2018

I can retrieve a single image shared by another app to mine but I did not find an example retrieving multiple images. Manifest:

B4X:

AddActivityText(Main,
<intent-filter>
    <action android:name="android.intent.action.SEND" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="image/*" />
</intent-filter>
<intent-filter>
    <action android:name="android.intent.action.SEND_MULTIPLE" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="image/*" />
</intent-filter>)

which works but here I got stuck ("ACTION_SEND_MULTIPLE" isn't a member of...)

B4X:

Sub Activity_Resume
    If IsRelevantIntent(Activity.GetStartingIntent) Then
        Dim in As JavaObject = Activity.GetStartingIntent
        Dim uri As String = in.RunMethod("getParcelableExtra", Array("android.intent.extra.STREAM"))
        Try
            Log("Loading bitmap from: " & uri)
            Dim bmp As Bitmap = LoadBitmapSample("ContentDir", uri, 100%x, 100%y)
            Activity.SetBackgroundImage(bmp)
        Catch
            Log(LastException)
        End Try
    End If
End Sub

Private Sub IsRelevantIntent(in As Intent) As Boolean
    Log(in.Action)
    If in.IsInitialized And in <> OldIntent And (in.Action = in.ACTION_SEND Or in.Action = in.ACTION_SEND_MULTIPLE) Then
        OldIntent = in
        Return True
    End If
    Return False
End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

Can you please post a log of the content(data) of the startingintent?
Maybe you just not get a android.intent.extra.STREAM but instead you got something other.
I saw a code in the past. I´m pretty sure that it works. Maybe i did wrote the code

Thanks @DonManfred

Another solution (it works with 1-n images) but I don't know if the code is elegant as I get everything from Extras searching for "content://".

Manifest

B4X:

AddActivityText(Main,
<intent-filter>
    <action android:name="android.intent.action.SEND" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="image/*" />
</intent-filter>
<intent-filter>
    <action android:name="android.intent.action.SEND_MULTIPLE" />
    <category android:name="android.intent.category.DEFAULT" />
    <data android:mimeType="image/*" />
</intent-filter>)

Code

B4X:

Sub Activity_Resume
    Dim ImageList As List
    ImageList=GetImages(Activity.GetStartingIntent)
    If ImageList.Size>0 Then
        
        Dim uri As String = ImageList.Get(0) 'Just the first image
        Try
            Log("Loading bitmap from: " & uri)
            Dim bmp As Bitmap = LoadBitmapSample("ContentDir", uri, 100%x, 100%y)
            Activity.SetBackgroundImage(bmp)
        Catch
            Log(LastException)
        End Try
    End If
End Sub

Private Sub GetImages(in As Intent) As List
    Log(in.Action)
    Log(in.GetData)
    Log(in.ExtrasToString)
    Dim ImageList As List
    ImageList.Initialize
    If in.IsInitialized And in <> OldIntent Then
        If in.Action = "android.intent.action.SEND" Or in.Action= "android.intent.action.SEND_MULTIPLE" Then
           ImageList= GetImagePathsFromExtras(in.ExtrasToString)     
        End If
        OldIntent = in
    End If
    Return ImageList
End Sub

Sub GetImagePathsFromExtras (Extras As String) As List
    Log(Extras)
    Dim ImageList As List
    ImageList.Initialize
    If Extras.StartsWith("Bundle") Then
        'Bundle[{makeup=false, KEY_ITEM_ORIENTATION_LIST=[0, 0], food=false, KEY_ITEM_MIME_TYPE_LIST=[image/*, image/*], KEY_MEDIA_SET_PATH=/local/camera, android.intent.extra.STREAM=[content://media/external/images/media/13930, content://media/external/images/media/13935]}]
        Dim pos As Int = Extras.IndexOf("content://")
        If pos >=0 Then
           Extras=Extras.SubString2(pos-1,Extras.Length) 'Not that elegant, but it works
           Extras=Extras.Replace("}","")
           Extras=Extras.Replace("[","")
           Extras=Extras.Replace("]","")
           Extras=Extras.Replace(" ","")
           Extras=Extras.Replace("=","")           
           Log(Extras)
            Dim Images() As String
            Images = Regex.Split(",", Extras)
            ImageList.Initialize2(Images)
            Log(ImageList)
        End If
    
    End If
    Return ImageList
End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub

i personally find my verson more elegant

B4X:

  If starting.Action = "android.intent.action.SEND_MULTIPLE" Then
            Log("Multiple")
            Dim intents As List = inte.RunMethod("getParcelableArrayListExtra", Array("android.intent.extra.STREAM"))
            'Log(intents)
            If intents.Size > 0 Then
                For i = 0 To intents.Size-1
                    Dim fle As String = intents.Get(i)
                    Log("File: "&fle)
                Next
            End If
            Log("Multiple")

Did not knew about this

B4X:

getParcelableArrayListExtra

Yep. I fully agree. Will change my code. I always appreciate to learn better ways

me too. But i tried to convert the sending part

fredo said:
For Each image As String In images
Dim u As Uri = CreateFileProviderUri(Starter.strSharedFolder, image)
Uris.Add(u)
Next

Dim jo As JavaObject = i
jo.RunMethod("putParcelableArrayListExtra", Array As Object("android.intent.extra.STREAM", Uris))
i.Flags = 1

putParcelableArrayListExtra works. I just try to change it to use
getParcelableArrayListExtra instead to get the list back. And it worked
