I get the Error
Unable to start activity ComponentInfo{de.androidbuch.activiti/de.androidbuch.activiti.task.Activity}: android.view.InflateException: Binar
None of the solutions mentioned above helped me. In the log I could find the detail of the exception as mentioned below:
06-19 16:20:37.885: E/AndroidRuntime(23973): Caused by: java.lang.RuntimeException: API key not found. Check that /meta-data/ android:name="com.google.android.maps.v2.API_KEY" android:value="your API key"/ is in the application element of AndroidManifest.xml.
I did this and my code was working!
