No such file or directory when caching bitmap?

I keep getting this error

07-28 19:32:40.536: ERROR/error(534): java.io.IOException: No such file or directory
07-28 19:32:40.536: ERROR/error(534):     at java.io.File.createNewFileImpl(Native Method)

07-28 19:32:40.536: ERROR/error(534):     at com.fttech.gameIT.MainMenu.putBitmapInDiskCache(MainMenu.java:447)

Here is my putBitmapInDiskCache()

    public void putBitmapInDiskCache(URI imageUri, Bitmap avatar) {   

                    File cacheDir = new File(this.getCacheDir(), "thumbnails");    
                    File cacheFile = new File(cacheDir, ""+imageUri.hashCode());     
                    try {      
                    cacheFile.createNewFile();       
                    FileOutputStream fos = new FileOutputStream(cacheFile);    
                    avatar.compress(CompressFormat.PNG, 100, fos);       
                    fos.flush();       
                    fos.close();    
                    } catch (Exception e) {      开发者_如何学Go 
                    Log.e("error", "Error when saving image to cache. ", e);    

                    }  



                    }

EDIT: That worked! Now i get this...

Code i am using to retrieve the images from the cache..

try {


                                URL aURL = new URL(myRemoteImages[position]);



                                URI imageUri = null;

                                    imageUri = aURL.toURI();
                                } catch (URISyntaxException e1) {

                                    e1.printStackTrace();
                                }

You are missing a cacheDir.mkdirs() call. Do that and then do File cacheFile...
