Android Question Opening/Saving Email Attachment using B4xpages

[gregchao]

I was reading this old thread which uses manifest and intent to save an email attachment to the local app folder. With the B4xpages, this method no longer seems to work. Is there some modifications that I need to make? Or, is there another method.

My intention is to export a .zip file in an email on one device and the import the enclosed file in another device running the same app.

Get file from email attachment

Hi, I'm trying to open an email attachment from my App, I have managed to create an intent listener and open an activity. The intent content is: Action: android.intent.action.VIEW GetData: content://gmail-ls/javier@gmail.com/messages/2672/attachments/0.1/BEST/false GetExtra: null ExtraStr: no...

Many things related to external resources have changed in Android. The latest and most important example is this one: https://www.b4x.com/android/forum/t...-save-and-load-external-files.132731/#content
I think that it includes the functionally that you are looking for.

Thanks. Got it working.

I ended up using the share button code option. The only change I had to make is changing the MIME type from text to zip.

Private Sub btnShareFile_Click
     'fill MyArray with your files to zip
     Dim FileToSend As String = "example.zip"
     Arc.AsyncZipFiles(LocalDirFullPath, myArray, Provider.SharedFolder, FileToSend, "Zip")
     Wait for Zip_ZipDone(CompletedWithoutErrors As Boolean, NbOfFiles As Int)
    Dim in As Intent
    in.Initialize(in.ACTION_SEND, "")
    in.SetType("application/zip")  'changed from in.SetType("text/plain")
    in.PutExtra("android.intent.extra.STREAM", Provider.GetFileUri(FileToSend))
    in.Flags = 1 'FLAG_GRANT_READ_URI_PERMISSION
    StartActivity(in)
End Sub

Again, the only change I had to make was in FileHander Module to change from text to zip file format.

Public Sub Load As ResumableSub
    Dim cc As ContentChooser
    cc.Initialize("cc")
    cc.Show("application/zip", "Choose zip file")  'changed from cc.Show("text/*", "Choose text file")
    Wait For CC_Result (Success As Boolean, Dir As String, FileName As String)
    Dim res As LoadResult = CreateLoadResult(Success, Dir, FileName)
    If res.Success Then ExtractInformationFromURI(res.FileName, res)
    Return res
End Sub
