file explorer in android

I made a program for simple database with the database name "employee.db" but i'm not finding the file explorer where i can see that if d开发者_运维问答atabase is created or not. while running the code i'm getting this :- [2011-09-09 14:52:19 - DatabaseExample] Failed to install DatabaseExample.apk on device 'emulator-5554': null [2011-09-09 14:52:19 - DatabaseExample] com.android.ddmlib.InstallException [2011-09-09 14:52:19 - DatabaseExample] Launch canceled!

If you are using Eclipse for development then download the Android development plugins and use the File Explorer in the DDMS perspective.

Alternativeley you could also use the adb -shell command from the Android SDK platform-tools to browse the file system.
