ImagePrintJob on Clover Mini (devkit)

Does anyone have ImagePrintJob working? It looks like it tries to save the passed bitmap to a file before sending the job and that step is failing;

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.lee.printticket/com.example.lee.printticket.Main}: java.lang.NullPointerException

java.io.IOException: open failed: ENOENT (No such file or directory)

When I debug it's falling over in ImagePrintJob.java (part of com.clover.sdk);

File dir = new File("/sdcard", "clover" + File.separator + "image-print");

Do you have permission WRITE_EXTERNAL_STORAGE? Please provide the entire stack trace and surrounding logcat.

Also, the Clover Android SDK has examples that use ImagePrintJob. Under the clover-android-sdk-examples module, see PrintTestActivity.

Easy when you know how!

Adding; <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/> to the androidmanifest.xml did the trick!

I did take the code from the PrintTestActivity but of course it doesn't come with the relevant Manifest / permission entries.

Many Thanks
