Java Question Library that extends Activity

[lorebarita]

Hi. I am trying to create a library that extends Activity. Such that when user clicks a certain button I call StartActivity(activity_in_library). I have seen similar libraries that works the same.

Using SLC I am able to create the library successfully with the package name of my java project being (com.weight.example).
I then created a B4A project with the same package name(com.weight.example) and in the manifest I added


AddApplicationText(<activity android:name="WeightCaptureActivity">
<intent-filter>
<action android:name="com.weight.example.WeightCaptureActivity" />
</intent-filter>
</activity>)

to register the activity that I want to start in my library.
To start my activity I just call StartActivity("WeightCaptureActivity")
but I get the following error.

java.lang.ClassNotFoundException: com.weight.example.weightcaptureactivity

Please help. I have attached the library and the b4a sample example.

Not tested, but...

   Dim i As Intent
   i.Initialize("","")
  i.SetComponent("com.weight.example/com.weight.example.WeightCaptureActivity")
   StartActivity(i)

and in the manifest, this should be enough :

AddApplicationText(
<activity android:name="com.weight.example.WeightCaptureActivity">
</activity>)
