通过代码登录到特定的Google云端硬盘帐户

Question

Is it possible to login into a google account from an android device through code?

The reason i'm asking is this:

I want to use google drive to store the contents for an app, and then from the app read the folder structure of the GDrive contents and download whatever is necessary.

I want to hardcode the username and password for that particular account in my code and login.

Is it possible?

I have gone through various things available on the web including the Google Drive APIs but have not been able to figure out how to login to some specific account.

I am not looking for a complete solution, a nudge in the right direction would be fine!

Answer 1

Username/password, aka basic authorization is not supported. You need to go through OAuth 2.0 flow. GoogleAccountCredential intent does much of the work for you. See the Android quickstart sample .

If you don't want user interaction and want to create a Google Drive account for your app to serve files, you may embed an encrypted access token and a refresh token into your application and init a credential object with the embedded tokens. Please review security concerns before taking such a decision:

Credential credential = new GoogleCredential.Builder()
    .setClientSecrets("...")
    ....
    .build();

credential.setAccessToken(storedAccessToken);
credential.setRefreshToken(storedRefreshToken)
