check if .android_secure has the files for that app on the SD card?
I don't see that file. where is it ?
.android_secure is a folder there should be a file named com.bitcoinandroid.asec or something similiar in there. you'll need to use the ADB tool from the SDK to pull files from the secure format, I don't know the exact structure either but Yifu should and I already messaged him about it so when he gives a reply I'll let you know,
Good work on Electrum btw! (Yifu's pretty interested in it.)
