Android - Google Spreadsheet Api

I can't get which libs i should use for developing an Android app that menages Google spreadsheet. I need connecting, copying, editing, reading from a user spreadsheet but i can't understand today which is the way.

Google Drive Api : https://developers.google.com/drive/
Google Spreadsheet Api: https://developers.google.com/google-apps/spreadsheets/
Google APi java client: http://code.google.com/p/google-api-java-client/


Which is the correct one?

Answer

At the end the libraries i used are:

gdata-client-1.0.jar
gdata-client-meta-1.0.jar
gdata-core-1.0.jar
gdata-spreadsheet-3.0.jar
gdata-spreadsheet-meta-3.0.jar
google-api-client-1.12.0-beta.jar
google-api-client-android-1.12.0-beta.jar
google-http-client-1.12.0-beta.jar
google-http-client-android-1.12.0-beta.jar
google-oauth-client-1.12.0-beta.jar
gson-2.1.jar
guava-13.0.1.jar
jackson-core-asl-1.9.9.jar
jsr305-1.3.9.jar
protobuf-java-2.4.1.jar

As suggested by Eugenio (thanks for that!!!) i "mixed" libraries from spreadsheet api with the java-client-api and after the authentication i used the following for getting the cells

SpreadsheetEntry spreadsheet = null;
URL metafeedUrl = new URL("https://spreadsheets.google.com/feeds/spreadsheets/private/full");

SpreadsheetFeed spreadsheetFeed = service.getFeed(metafeedUrl, SpreadsheetFeed.class);
List<SpreadsheetEntry> spreadsheets = spreadsheetFeed.getEntries();
for (SpreadsheetEntry entry : spreadsheets) {
   if (entry.getTitle().getPlainText().equals(spreadsheetTitle)) {
      spreadsheet = entry;
   }
}

if (spreadsheet == null) {
    throw new FileNotFoundException("Cannot find the required spreadsheet '" + spreadsheetTitle + "'");
}

WorksheetEntry worksheet = null;
WorksheetFeed worksheetFeed = service.getFeed(spreadsheet.getWorksheetFeedUrl(), WorksheetFeed.class);
List<WorksheetEntry> worksheets = worksheetFeed.getEntries();
    for (WorksheetEntry entry : worksheets) {
    if (entry.getTitle().getPlainText().equals(worksheetTitle)) {
         worksheet = entry;
    }
}

if (worksheet == null) {
    throw new FileNotFoundException("Cannot find the required worksheet '" + worksheetTitle + "'");
}

URL listFeedUrl = worksheet.getListFeedUrl();
ListFeed listFeed = service.getFeed(listFeedUrl, ListFeed.class);

For the moment i used the "worst" authentication system and i should turn this in the OAuth2 but for the moment the ClientLogin is done in this way:

SpreadsheetService service = new SpreadsheetService("v1");
service.setProtocolVersion(SpreadsheetService.Versions.V3);
service.setUserCredentials(email, password);
