The first code was OK, since android:targetSdkVersion="26"
Error: Service Intent must be explicit...
With the others there is no reaction in the Provider APP
Requester App:
Dim in As Intent
in.Initialize("provider.app.REQUEST","")
'in.SetComponent("provider.app/.S1")...
addservicetext
android.intent.category.default
android:exported
in.addcategory("android.intent.category.default")
in.setcomponent
p.sendbroadcastintent(in)
setreceiverattribute
start service in a second app with intent
targetsdkversion="26"
