Bug on Android Core API

Pedro V.5

When using the Dropbox Core API, if the Dropbox app is not installed, when trying to open the URL to authenticate on the browser the following error happens:

E/com.dropbox.client2.android.AuthActivity(19192): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.intent.action.VIEW dat=www.dropbox.com/1/connect?locale=...&k=...&n=...&s=&state=oauth2:... flg=0x60000000 }

This can be fixed by adding the following validation on line 620 of AuthActivity.java :: startWebAuth(String state)

if(url != null && url.startsWith("www.")){
     url = "http://" + url; 
}

Note: This does not happen on every device.

Thanks for the report! We'll look into it.

Can you let us know more about the devices where you see this? I.e.:

What version(s) of Android are they running?
What browsers are available, and what versions are they?

Pedro V.5

One device where it happens:

Samsung SM-P600
Android 4.4.2
Browsers: Chrome, Firefox, Internet (default)

Thanks! I'm working on reproducing this, but I can't seem to get the SDK to give me a URL that doesn't have the "https://" at the beginning, which seems to be the important difference, per the exception in your posted log. The URL is built by RESTUtility.buildURL in com/dropbox/client2/RESTUtility.java. That only returns either null (in case of an UnsupportedEncodingException) or:

return "https://" + host + ":443" + target;

Is your RESTUtility.buildURL modified by any chance?

Otherwise, can you try adding some logging to see if/where it's getting modified? E.g., something like this between RESTUtility.buildURL and Intent intent = new Intent... in startWebAuth:

Log.d("TEST", "url: " + url);
Log.d("TEST", "parsed URI: " + Uri.parse(url));

Sorry, you're absolutely right. This was our fault.
