Android Question Intent Issue

[techknight]

Hey, I have a different developer who isnt familiar with B4A, and codes natively with the android environment.

So to get our two apps to speak together, we have chosen to use Intents assuming they will work as intended.

His program is a background service.

Mine is a foreground activity.

But for some reason, I cant get intents to work. it keeps crashing with ActivityNotFoundException.

His background service manefest has this:
<receiver android:name="com.majordisplay.jashanno.broadcastreceivertest.PacketReceiver">
<intent-filter>
<action android:name="com.majordisplay.jashanno.packetbroadcast"/>
</intent-filter>
</receiver>

My intent code is this:

Sub cmdSendIntent_Click()
    Dim Intent1 As Intent
    Intent1.Initialize("com.majordisplay.jashanno.broadcastreceivertest.PacketReceiver", "")
    Intent1.SetComponent("com.majordisplay.jashanno.packetbroadcast")
    Intent1.PutExtra("value", txtPacket.Text)
    StartActivity(Intent1)
    ToastMessageShow("Intent Sent", True)
  
End Sub

Any ideas?

Hello,
Excuse me, I am not an expert but if I remember correctly, sometimes ago I read something like StartService(theIntent) instead of StartActivity in such cases
Could you try ?

 

[techknight]

Well in real java its

sendBroadcast(intent);

Which I dont see such a thing in B4A

Perhaps could you find something here :https://www.b4x.com/android/forum/threads/tutorial-inter-app-communication-with-intents.30608/

You can get the broadcat sent by the other app with the broadcastreciever library.

To send a message to the app you should be able to send an intent to the app directly.
You can try to use the packagemanager to get the starting-intent for the app...

Additional refer to the thread @lemonisdead provided in post #4

I found my issue. Instead of StartActivity(Intent1), I did phone.SendBroadcastIntent, and that works...

You should use CallSubDelayed.
