RuntimeException with "Bad request 400" for certain start index

[GoogleCodeExporter]

What steps will reproduce the problem?

Market API throws bad request "Response code = 400, msg = Bad Request" for
certain indexes. 
    private static MarketSession newSession() {
        MarketSession session = new MarketSession();
        session.login("########", "#####");
        return session;
    }

    public static void main(String[] args) throws Exception {
        MarketSession session = newSession();
        MarketSession.Callback callback = new MarketSession.Callback() {
            public void onResult(ResponseContext context, Object response) {
                showCount();
            }
        };
        AppsRequest appsRequest =
AppsRequest.newBuilder().setStartIndex(190).setEntriesCount(

10).setAppType(AppType.APPLICATION).setWithExtendedInfo(false).build();
        session.append(appsRequest, callback);
        session.flush();
    }

What is the expected output? What do you see instead?

Expected: List some applications, or useful message.
Actual: RuntimeException with bad request. 

What version of the product are you using? On what operating system?
The latest API.

Please provide any additional information below.

"Expected: List some applications, or useful message."

The request your making isn't valid.

Since this api doesn't perform validation prior to submitting the request, the 
market
is rejecting the request and only giving a 400 as a response. It doesn't 
actually
return useful information, so there is nothing for this api to tell you other 
than
that :)

@quickbook123

Not it one request, you must make multiple requests to do so

@greenmaomao @lberger

That's out of scope of this issue - and it requires more work than this api 
currently
has done.

I perform the same query with different indexes (less than 800) and sometimes i 
get response code 400. I couldn't find a pattern that generates this error and 
there is not much info returned by API. Do you have an idea about the market 
limitations? Like number of requests allowed ...

In MarketSession.executeRawHttpQuery(byte[] request){
    ....
    String request64 = Base64.encodeBytes(request);
    ....
}

This "request64" sometimes contains a '/' character.
If you replace this '/' to '-', bug will be fixed.

debug1984213, thank you so much,

just encode the bytes with options URL_SAFE, 
now everything works fine. 

String request64 = Base64.encodeBytes(request, Base64.URL_SAFE);
