Android Question [solved] Problem receiving intent from tasker

[Creideiki]

Hi,

I'm trying to control my B4A-App with tasker. Tasker sends an intent to my App, but it seems not to recieve it.

I read e.g. https://www.b4x.com/android/forum/threads/20103/#content and https://www.b4x.com/android/forum/threads/31136/#content.
I think I've done anything to recieve the broadcast, but when I trigger the intent with tasker, nothing happens. It seems I missed something relevant.

My manifest includes:

AddReceiverText(WebSend, <intent-filter>
  <action android:name="de.helmutbender.setstatus.NEW_STATUS" />
   <category android:name="android.intent.category.DEFAULT" />
</intent-filter>)

My service WebSend includes:

Sub Service_Start (StartingIntent As Intent)
	Log("Starting WebSend with " & StartingIntent.Action & " : " & StartingIntent.GetData)
	If StartingIntent.Action = "de.helmutbender.setstatus.NEW_STATUS" Then
		Dim s As String = StartingIntent.GetData
		Log("NEW_STATUS to " & s)
		If IsNumber(s) Then
			CallSubDelayed2(Main, "ChgStatus", s)
		Else
			Log(" => is not a number!")
		End If
	Else
		InitiateWebUpdate
	End If
End Sub

The service is called from Main to send the status update to a web server (InitiateWebUpdate), too.
When I trigger the Update from the App, it's working. When I send the intent from tasker, it doesn't log anything.

tasker has the following definition:

Action: de.helmutbender.setstatus.NEW_STATUS
Type: Default
Data: [e.g.] 6
Target: broadcast receiver

What do I do wrong?

Have you tried to remove the category?

Also add this line:

SetReceiverAttribute(WebSend, android:exported, true)

Something I'm doing wrong.
I removed the <category> tag and added the SetReceiverAttribute. Still no reaction when triggering the task in tasker.
I changed the type of the task from 'default' to 'none', still no success.

Is there a tool with which one can debug broadcasts?

You can send an intent yourself from a different app with Phone.SendBroadcast (to test it).

OK. I set up a tiny app from scratch with

Manifest

'This code will be applied to the manifest file during compilation.
'You do not need to modify it in most cases.
'See this link for for more information: https://www.b4x.com/forum/showthread.php?p=78136
AddManifestText(
<uses-sdk android:minSdkVersion="5" android:targetSdkVersion="14"/>
<supports-screens android:largeScreens="true"
  android:normalScreens="true"
  android:smallScreens="true"
  android:anyDensity="true"/>)
SetApplicationAttribute(android:icon, "@drawable/icon")
SetApplicationAttribute(android:label, "$LABEL$")
SetApplicationAttribute(android:theme, "@android:style/Theme.Holo")
'End of default text.
AddReceiverText(Starter, <intent-filter>
  <action android:name="de.helmutbender.setstatus.NEW_STATUS" />
</intent-filter>)
SetReceiverAttribute(Starter, android:exported, true)

Main includes a button with

Sub btISend_Click
   Dim myIntent As Intent
   myIntent.Initialize("de.helmutbender.setstatus.NEW_STATUS", "6")
   Dim p As Phone
   p.SendBroadcastIntent(myIntent)
   Log("IntentTester: Intent sent.")
End Sub

Starter has changed only one line

Sub Service_Start (StartingIntent As Intent)
   Log("IntentTest starting with " & StartingIntent.Action & " : " & StartingIntent.GetData)

End Sub

I think, an app should be able to recieve it's own intents, shouldn't it?
Are there any permissions I should set?

BTW: The 'Intent sent' from the _Click is logged, the 'IntentTest starting with...' is not.

Note that you shouldn't use the Starter service for this as it is a special service. Create a different service.

It will work if you remove the data component:

myIntent.Initialize("de.helmutbender.setstatus.NEW_STATUS", "")

Or you can add a scheme to the intent filter:

AddReceiverText(service1, <intent-filter>
  <action android:name="de.helmutbender.setstatus.NEW_STATUS" />
    <data android:scheme="helmut" />
</intent-filter>)

myIntent.Initialize("de.helmutbender.setstatus.NEW_STATUS", "helmut://1")

Or you can add a scheme to the intent filter

Or you can use my new library released here as tutorial. It sets a scheme too but have an configurable json file to delegate different urls to different activities.

Why is it special? What should I do with it?

Or you can add a scheme to the intent filter:

AddReceiverText(service1, <intent-filter>
  <action android:name="de.helmutbender.setstatus.NEW_STATUS" />
    <data android:scheme="helmut" />
</intent-filter>)

myIntent.Initialize("de.helmutbender.setstatus.NEW_STATUS", "helmut://1")

I didn't know the 'data' has definitly to be an URI. Now it works. Thank you very much!

Am I right I could use en Extra as well for the data?

Yes.

Just use a different service.
