Everytime I try to save something using the function writeAll(ArrayList liste), the application crash. Here are the logs : 

`E/AndroidRuntime: FATAL EXCEPTION: main

I try to use the function by tilting the phone.

    Please don't just link to your code off-site. You need to include a [mcve] in the question itself. – Mike M. Mar 09 '17 at 10:18

SerialisationSerieDAO pojo is not a activity. Therefore your context (contexte) this case was never initialized. Use a mutator to set a context .or pass one in a constructor.
