com.percolate.foam.ExceptionPersister

class ExceptionPersister
extends java.lang.Object

Class that allows us to store and load exception data to the device. This is done so that crashes can be sent the next time the application launches. Data is stored using androids context.openFileOutput, so no extra permissions are required since it uses internal storage. See http://developer.android.com/reference/android/content/Context.html#openFileOutput(java.lang.String, int)
