can not delete photos by the method "deleteFile"

[henryyohn]

I got the photo fileId by camera.getList(), then I would like to delete the photo by method "deleteFile" with the photo file id from thetasc2 camera. It will always fail: file not found.
W/System.err: java.io.FileNotFoundException: http://192.168.1.1/osc/commands/execute W/System.err: at com.android.okhttp.internal.huc.HttpURLConnectionImpl.getInputStream(HttpURLConnectionImpl.java:255) W/System.err: at com.krpano100.theta.network.HttpConnector.deleteFile(HttpConnector.java:601) W/System.err: at com.krpano100.theta.ImageListActivity$DeleteObjectTask.doInBackground(ImageListActivity.java:469) W/System.err: at com.krpano100.theta.ImageListActivity$DeleteObjectTask.doInBackground(ImageListActivity.java:457) W/System.err: at android.os.AsyncTask$3.call(AsyncTask.java:394) W/System.err: at java.util.concurrent.FutureTask.run(FutureTask.java:266) W/System.err: at android.os.AsyncTask$SerialExecutor$1.run(AsyncTask.java:305) W/System.err: at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1167) W/System.err: at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:641) W/System.err: at java.lang.Thread.run(Thread.java:923)
