Proguard problema con FragmentActivity

[oibaf79]

Ciao a tutti,

ho un problema con proguard, voglio solo offuscare il codice senza ottimizzarlo ma mi restituisce i seguenti warnings su una FragmentActivity (Detail):

Warning: Detail: can't find referenced method 'void setContentView(android.view.View)' in class Detail
Warning: Detail: can't find referenced method 'android.content.Intent getIntent()' in class Detail

Your input classes appear to be inconsistent.
You may need to recompile them and try again.
Alternatively, you may have to specify the option

Qualcuno potrebbe darmi qualche indicazione su come evitare questi warnings? (mi andrebbe bene anche di escludere la class dall'offuscamento).


Grazie
