i have a simple question: Should i resize a bigger bitmap before adding to a ImageView or let the ImageView resize the Bitmap? What's the right way, regarding performance?

I need help figuring out how to check if a device is equipped with the search hardware button or not. Is this possible?

Thanks for reading. I am facing a strange problem: My app behavior is such that when the Activity starts, I requestFocus() on an EditText and show the soft keyboard.

I'm trying to use the ActionBarSherlock library to provide backwards compatible ActionBar support with tabs in my Android app, so I downloaded the latest build, built the demo, and ran it.

When I switched from my debug map key to my signed map key my maps stop working. I get the following errors in logcat:

Some apps in the Android Market have a Top Developer badge under their name. For example: Facebook for Android .

Within the last days I do see increasing error messages that sound identical. I don't use tablets ActionBar - I'm developing for phones only.

I'm trying to enable hw acceleration in Honeycomb, and display some Bitmaps on Canvas. All works fine, but for large bitmaps (>2048 in one dimension), I get error in log:

I can't find good docs on PopupWindows showAtLocation and Gravity. After hacking for a few hours trying some black magic maths to calculate centers and try to align the view using Gravity.TOP I found a post that used Gravity.CENTER.

So I am thinking of getting Sprint Nexus S from ebay to do android development. I am wondering whether getting a locked phone will hinder me from doing any kind of development work on the phone (pushing to app market, connecting to internet(i don't care about 3/4G as long as I can use wifi I am good)).

After adding Google Guava r09 to our Android project the build time increased significantly, especially the DEX generation phase. I understand that DEX generation takes all our classes + all jars we depend on and translates them to DEX format. Guava is a pretty big jar around 1.1MB
