I tried Arjan’s method and unfortunately it didn’t work.

However if you go into the Manifest and change your min sdk to this:

it should work

hi, we have created an app for android devices, its called: SpriteTester.
we have developed the tool, and it´s free, you can find it in google play.
You can visualize your sprites and improve them by loading, selecting parameters as columns, rows, speed, frame to frame and color background.
Hope it is useful for indie developers 😀

Thanks to arjan franzen……
I ws getting problem before I replace my code as per your instruction..

Hello frnds, If you use this code then it will work proper for mdpi devices, but for getting same result in ldpi and hdpi, you should just replce 1 line with 4 lines as per arjan franzen told.
then it will work fine…
Thanks to maximo also to share it….

Hi, The problem with the cut-in-half has to do with the picture i think

if you replace the code
tileSheet = BitmapFactory.decodeResource(context.getResources(), spriteid );

with:
BitmapFactory.Options options = new BitmapFactory.Options();
options.inDensity = 1;
options.inTargetDensity = 1;
tileSheet = BitmapFactory.decodeResource(context.getResources(), spriteid, options);

you instruct that it should be interpreted as 1 pixel density. and the idle animation appears!

good luck

Arjan

Your code would look a lot better if it was posted in sourcecode tags. So all the spacing and color highlighting would show up.

–Your code:
public void loadSprite(int spriteid, int xmlid, Context context) {
tileSheet = BitmapFactory.decodeResource(context.getResources(), spriteid);
//load the xml will all the frame animations into a hashtable
XmlResourceParser xpp= context.getResources().getXml(xmlid);// this is the last line, you dont modify nothing after this

–My code:
public void loadSprite(int spriteid, int xmlid, Context context) {
sBitmapOptions.inPreferredConfig = Bitmap.Config.RGB_565;
InputStream is = context.getResources().openRawResource(spriteid);
try {
tileSheet = BitmapFactory.decodeStream(is, null, sBitmapOptions);
}finally {try {
is.close();
} catch (IOException e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}}
//load the xml will all the frame animations into a hashtable
XmlResourceParser xpp= context.getResources().getXml(xmlid);// after this all are =
