getClass   getResourcesAsStream   works fine on Android  Just make sure the file you are trying to open is correctly embedded in your APK  open the APK as ZIP    Normally on Android you put such files in the assets directory  So if you put the raw resources dat in the assets subdirectory of your project  it will end up in the assets directory in the APK and you can use   getClass   getResourcesAsStream   assets raw resources dat      It is also possible to customize the build process so that the file doesn t land in the assets directory in the APK

InputStream in   getResources   openRawResource resourceName     This will work correctly  Before that you have to create the xml file   text file in raw resource  Then it will be accessible   Edit   Some times com andriod R will be imported if there is any error in layout file or image names  So You have to import package correctly   then only the raw file will be accessible

For raw files  you should consider creating a raw folder inside res directory and then call getResources   openRawResource resourceName  from your activity
