I wrote (and published) unofficial port of Riesel Problem app for Android. Unfortunatelly during computations Android killed apps and boinc sent result to your server. One of incorrect result was ACCEPTED by your validator even it was INCORRECT. Incorrect result: http://www.primegrid.com/result.php?resultid=400143100. Currently I am working on fixing this problem on application's side. I am using sources from https://sites.google.com/site/geoffreywalterreynolds/programs/sr2sieve and [url]http://sourceforge.net/projects/primegrid/[url]. My sources available at https://github.com/matszpk/native-boinc-for-android/[/url].

There's a difference between "invalid" and "incorrect".

While the results were not the expected correct results, they were, however, valid.

Your results returned no factors, which is a valid result for a sieve WU.

but this workunit finished unexpectedly (stopped at 45.8398% progress by signal or other reason). Sometimes android can kill application when it have too small amount of the memory. I found bug in the sr2sieve wrapper (can handle improperly unexpected app exits, for example kills, termination by signal).
