Question

All,

I cannot find any threads where this issue has been brought up before, so I must be missing something ridiculously easy. I’m new to android and am playing around with creating an inputmethod. I yanked out all of the android code for the lock screen and when I view it on the emulator or on a Samsung Galaxy, the fonts on the buttons look perfect. But when I look at them on my HTC Sensation, everything is terribly pixelated. At first I thought the problem was with the sym_keyboard_numX image files, but I tested two things to make sure that wasn’t the case:

1. I originally had both hdpi and mdpi images for those. I removed the mdpi images leaving only the hdpi to ensure the wrong images weren’t being loaded.
2. I tried using a keyLabel instead of the images for the numbers and the text is still terribly pixelated.

I’ve looked through all of the code looking for any values that could affect quality and can’t find anything. I appreciate any help!

Here is the xml file defining the keyboard. You will see that I am using keyLabels in most of the buttons with a few keyIcons to test the difference. As I said, there is no difference. I don’t know of any other code that would be useful for you.

Answer 1

Apparently this question has come up before but I never came across it in all of my searching. Probably just the wrong search terms. I even went through all of the stackoverflow suggestions before posting my question, but one of the Related posts had my answer: https://stackoverflow.com/questions/6496870/assets-look-grainy-pixelated?rq=1

Basically I had to add a minSdkVersion (targetSdkVersion?) and the supports-screens as follows:
<supports-screens android:resizeable="true" android:largeScreens="true"/>
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="10"/>
