How to programmatically upload file from android to Google Drive (eclipse development)

For purpose I created out this post of tutorial simply felt sympathy to lack of practical + example documentation and a lot of mistake (found on "https://developers.google.com/drive/quickstart-android" ) support to programmatically upload file from Android to Google Drive by using Oath2 authority protocol (You must use it not other choises). Mostly if you have account setup on your gmail account on your android phone, it will automatically upload it to Google somethings known backend server which is not provide support to browseable but only sync it, but I preferred always "Do It Yourself (DIY)", with this ability you can master it to upload even sync your offline document , message, sms or contact details to your google drive for future see able or even your want to share it with your partners.

I've grind it until taken 13 day simply to under for all of these awesome Things!!!!

11.Don't forget include below external Google Drive API lib into libs folder of your project location.

   

12. Last for your manifest file, you need to include four lines of below to allow access permission.

   <uses-permission android:name="android.permission.USE_CREDENTIALS" /> 

    <uses-permission android:name="android.permission.MANAGE_ACCOUNTS"/> 

    <uses-permission android:name="android.permission.GET_ACCOUNTS" />

    <uses-permission android:name="android.permission.INTERNET" />
