Tip
When you run your applications in the emulator, the Eclipse workbench automatically signs the application
using a debug key store. This key store can be found in
%USERPROFILE%\debug.keystore
(in Windows) and
$HOME/.android/debug.keystore
(in Linux). The debug key store password is
"android"
, and the key alias and
password are
androiddebugkey/android
.
Signing the Application
Prior to the Android SDK 1.5, the application signature had to be done manually using the Java SDK
jarsigner
command (see Listing A-1).
