I want to integrate Google, Yahoo and OpenID in my android application. I have successfully done with facebook, twitter. I had used facebook android sdk for facebook integration and twitter4j-core-android-2.2.3.jar for twitter integration. Now I am looking for Yahoo, Google and openId integration. I searched for yahoo integration also registered to get consumer key, consumer secrete key and application id. But I didn't find any jar or sdk for yahoo integration. There is for iPhone but not any thing for android.

I currently have a application targeted at android 2.3 (api level 10), but went thinking that probably people using android 2.1/2.2 or older won't even be able to see the application in the market.

I came across this relatively old post which describes how impressively Nexus One's noise cancellation works and I was wondering where can I find more information about its implementation in the OS software.

When adding a google map view (I extended a MapView, used the xml editor to add it to the Activity, and added my google maps api key to the layout xml file manually)

In Android, you can specify the texts in the default locale in res/values/strings.xml . Additional translations can be added for new languages in res/values-it/strings.xml (for Italian for example). If a string is not translated, the fallback-default locale is used.

Problem: I add a fragment to a LinearLayout, programmatically. It shows up in my activity, great. I turn the device —> configuration changes: everything is destroyed to be recreated. But, before onDestroy() is called, onSaveInstanceState() should be called. It is the case for the parent activity, but not for the fragment I've added. Why ?

So I thought I could now upload my app using different NDK compiled libraries for targeted CPU architectures but it seems like that's not possible.
