Hi,

I am trying to send a pdf in files folder thru WhatsApp as below but it shows "No app can perform this action" .

In starter I have only declared
Dim Provider as FileProvider

In Manifest
B4X: 
AddApplicationText(
  <provider
  android:name="android.support.v4.content.FileProvider"
  android:authorities="$PACKAGE$.provider"
  android:exported="false"
  android:grantUriPermissions="true">
  <meta-data
  android:name="android.support.FILE_PROVIDER_PATHS"
  android:resource="@xml/provider_paths"/>
  </provider>
)

CreateResource(xml, provider_paths,
   <files-path name="name" path="shared" />
)

In btnSend_Click
B4X: 
Sub SendPDF(sNumber As String)
    Starter.provider.Initialize
    File.Copy(File.dirassets,"document.pdf",Starter.Provider.SharedFolder,"document.pdf")
    Dim sendIntent As Intent
    sendIntent.Initialize(sendIntent.ACTION_MAIN,"")
    sendIntent.Action=sendIntent.ACTION_SEND
    sendIntent.SetPackage("com.whatsapp")
    sendIntent.SetComponent("android/com.android.internal.app.ResolverActivity")
    sendIntent.putExtra("jid", sNumber & "@s.whatsapp.net")
   
    sendIntent.PutExtra("android.intent.extra.STREAM", Starter.Provider.GetFileUri("document.pdf"))
    sendIntent.PutExtra("android.intent.extra.TEXT","")
    sendIntent.SetType("application/pdf")
    sendIntent.Flags=1
    StartActivity(sendIntent)
End Sub

I think i am missing something. Erel has mentioned files-path=File.DirInternal. I am not using that folder.

Can someone pls give some clue.

Thanks
Juzer

Thanks Erel,

No I am not able to send plain text also.

B4X: 
Dim sendIntent As Intent
    sendIntent.Initialize(sendIntent.ACTION_MAIN,"")
    sendIntent.Action=sendIntent.ACTION_SEND
    sendIntent.SetPackage("com.whatsapp")
    sendIntent.putExtra("jid", number & "@s.whatsapp.net")
    sendIntent.PutExtra("android.intent.extra.TEXT","Trial Msg")
    sendIntent.SetType("text/plain")
    StartActivity(sendIntent)

Shows error as below-:

Error occurred on line: 59 (frmWASender)
android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.SEND typ=text/plain flg=0x20001 pkg=com.whatsapp clip={text/plain T:Trial Msg} (has extras) }

I checked in forum the set component is used everywhere like that only.

B4X: 
    Dim Intent1 As Intent
    Intent1.Initialize(Intent1.ACTION_SEND, $"https://api.whatsapp.com/send?phone=${"91123456789"}&text=${"Hello"}"$)
    StartActivity(Intent1)

This code opens Whatsapp with msg. Just checked I don't need this.

se this

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

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...
www.b4x.com

try also
B4X: 
<manifest package="com.example.app">
    <queries>
        <package android:name="com.whatsapp"/>
        <package android:name="com.whatsapp.w4b"/>
    </queries>
  ...
</manifest>

Erel, Sorry the problem was i use Whatsapp Business for it package name is "com.whatsapp.w4b". Now WhatsApp is opening with PDF.
We still need to click send button to actually send it. Is there any way to automate it.
