minsdk problem in android

I developed application on 1.6.in manifest i gave:

<uses-sdk android:minSdkVersion="3" android:targetSdkVersion="4"/>.

When I run application in android 1.5 version.i am getting error

java.io.FileNotFoundException: res/drawable/title_bar_shadow.9.png

If I make one drawable folder and keep the images inside drawable. It is working 开发者_JAVA百科is it good for make one drawable folder with android 1.6.

How to make it run on android 1.5?

Please move the images under [drawable-mdpi] to [drawable] folder. This should solve your problem.

Where did you place the title_bar_shadow.9.png? If your 9patch is in a drawable-[ldpi|mdpi|hdpi] folder it will not work.

Check this thread to see how to fix it.
