Of course, the password is android and alias is androiddebugkey.
I finded MD5 and SHA1 and etc. from this page:
How to find out which key was used to sign an app?
My app build by eclipse and exist in bin folder (not use File > Export > Export Android Application).
in AndroidManifest.xml android:debuggable is false
Can recreate debug.keystore from this data ? and signed again for new update ?
