Question

I want to test my application on actual device, so how can I go for it? And is it accessory to sign in and use zipalign for this purpose, or they are useful when preparing for publish my application? And is there any way to test my application on actual device without using eclipse?

Answer 1

Yes u can directly install your application into actual device without signing and zipalign. You can install the drivers for your software into your computer and use you device directly for debugging alternative to Emulator

Refer Using Hardware Devices

or you can install using Android adb tool Refer Installing an Application

or you can directly copy your application package file to you sdcard and install

The easy steps to install your apk using File manager :

1. Copy the APK
   file you want to install to your phone’s memory card.
   And disconnect Phone from USB.
2. Go to Android Market and search and download Astro File Manager.
3. Click on the Install button.
4. After it is installed, open the app (Astro).
5. It will show you your application APK file stored directly in the root directory of your memory card.
6. Just tap on the application you want to install
7. Tap on “Open App Manager”
8. Click Install
9. You are done!

P.S: Don’t forget to enable Unknown sources in Settings > Security.
And when installing via Eclipse enable USB Debugging > Developer Options
