Class com.facebook.FacebookActivity Not Found on Initialising Facebook SDK on Android

Question

We are trying to integrate Facebook SDK in our project. We are not using (and won't) Android Studio. Facebook SDK is delivered as a .AAR file (dedicated to Android Studio). To be able to use it, as it is a simple .ZIP file, we have extracted required files (classes.jar, resources).

Following the documentation:

• We have modified our AndroidManifest.xml to add meta-data, facebook activities.

• We have modified our strings.xml to add a string .........

• In our project.properties we have modified target to android-21 so that resources can be compiled

• We are not using proguard

Then:

• Compilation is finishing with no error

• When calling FacebookSdk.sdkInitialise(....) we have a lock up and we are are receiving the following error in log:

Does anyone have any idea of what's going on?

Answer 1

As long as I know com.facebook.FacebookActivity is not a part of facebook sdk now.

It seams that they start to merge manifest file (or ever doesn't need any activity any more)

You could downgrade library version or remove com.facebook.FacebookActivity from manifest file. But be sure about correct manifest merging in this case
