Official Facebook examples crashes (GraphApiSample)

Question

I started to work with facebook-android-sdk-3.5.2.

The SDK project also contains varius sample examples for using the api like:

• HelloFacebookSample: A simple activity you can log in and do stuff, it works great.

Next thing i wanted to try the next example called:

• GraphApiSample, which i had problem with.

After i launch this app, i got this error: (Logcat):

Well i see:

Caused by: java.lang.IllegalArgumentException: Both context and applicationId must be non-null

Okay, but i did not changed a thing in the code. It should be work, right?

I tried to:

• Delete project, and import

• Delete project, and add a new android project from existing code

• Clean my project

• Delete facebook sdk library dependency and reimport, then clean again.

Same result after all of these.

Please if somebody is familiar with this prob. help me.

E D I T:

For some reason, this official facebook sample does not contains appId. Thanks for the suggest!

Answer 1

Try to set the app_id in the strings.xml or add it. It is also mentioned in the getting started tutorial here: Documentation

An additional step: Create a meta-data with the name com.facebook.sdk.ApplicationId and the value @string/app_id in AndroidManifest.xml
