I installed Sl4A via this link : https://electrum.org/android.html
I wanted to run electrum on my Nexus 10. installation went fine, electrum was working (send & receiving btc).
Then, I upgraded to Android 5 (last version, lolipop I think). After that, I can't run any Python script via SL4A.
I checked logcat file, I saw some lines about permission & chmod, but not sure if it's related.
