Is there any free single-signon mechanism for Android that gracefully works with non-webapps? Say, something along the lines of...

I have this sprite rotating algorithm (its poorly named and just used for testing). It is so close, sprites drawn with it do rotate. Everyframe I can add +5 degrees to it and see my nice little sprite rotate around. The problem is, the other stuff drawn to the canvas now flickers.

Disabling a radiobutton does not 'grey out' the control in the same way as disabling a checkbox. I was thinking, how difficult would it be to place a semi-transparent black bitmap over the whole radiobutton view, thereby making it appear darker?

The cursor contains a timestamp column in the format: yyyy-MM-dd HH:mm:ss.SSS, for example, 2010-08-27 21:25:30.575 Once retrieved, I set aSimpleCursorAdapter like so (code simplified): SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, R.layout...

When picking out contact details, is there a built in domain class they can be mapped to? Or, do you have to create your own? For example I do the following : ContentResolver cr = getContentResolver(); Cursor cur = cr.query(ContactsContract.Contacts.CONTENT_URI, null, null, null, null); String s = null; if (cursor.getCount() >...

I have an android game (see source at google source control) It's a card game, and I've used a method that redraws each hand every round - that might be wasteful but I couldnt think of a better way to do it. Here is the code fo...
I'm surprisingly frustrated by this, and I suspect the answer is simple. I have compiled and signed my android app using the Export Wizard, as described here in the section 'Compile and sign with Eclipse ADT'. I would like to backup the keystore and have it handy for future app updates, but I can't figure out for the life of me where t...
My application starts with a welcome screen Activity, but that screen has an option to skip that screen altogether in future launches. What's the proper Android way to do this? Initially, I just automatically detected the skipWelcome preference and switched to the 2nd activity from Welcome. But this had the effect of allowing the use...
I'm trying to follow the setup instructions on phonegap-android's wiki page, but I'm having trouble.
