Unable to start activity ComponentInfo{de.androidbuch.activiti/de.androidbuch.activiti.task.Activity}: android.view.InflateException: Binar
After one day struggle i found some scenario check may be you are facing same,
If everything is woking same as google code then please check manifest file in my case i added geo key and map key that's why exception occurs,
Note - do not add two keys in manifest file remove map key

android:name="com.google.android.maps.v2.API_KEY"
android:value="@string/google_maps_key"/>
