Can anyone point me in the right direction, so far googling has proved fruitless..

The key here is the line: android.content.res.Resources$NotFoundException: File res/drawable-mdpi/dialog_top_holo_dark.9.png from drawable resource ID #0x108022c1. This means that the runtime compiler cannot find the appropriate file dialog_top_holo_dark.9.png.

Now, it is looking in your /res/drawable-mdpi/ folder. If it is not defaulting back to res/drawable/, that means that often there is afile of that name detected, but there is an error reading the file. This means you need to do these things, in this order.

  1. First, make sure you have a file name dialog_top_holo_dark.9.png in your drawable folders.

  2. Second, make sure that the file ends with the .9.png extension.

  3. If the file does exist, but has a red X marking an error: Open the file in your graphics editor and resave the file with the same name.

  4. If this does not get rid of the red X, clean your project. In eclipse, this is done by clicking Project -> Clean in the menu.

  5. If this still does not resolve the issue, you may have to remake the file by scratch.

This sometimes happens if you import a .png or .9.png from the file system or from another project. Eclipse and the Android SDK does not always grab and copy the file properly. I've had this happen with a number of graphics files. As long as I follow the steps above, the problem becomes resolved permanently for that file in that project.

Hope this helps,

you just need to check the logs properly, it is clearly saying that it is not able to locate dialog_top_holo_dark.9.png, did you put that file in proper resource folder.

And one more thing, if you had put the file at correct location, just give the clean build, sometimes changes doesn't reflect, so its better to give clean build.
