nfc - Android Application Record compatibility with pre-ICS -

there's new method in ndefrecord allows writing androidapplicationrecord ndefmessage. not necessary in pre ice-cream-sandwich, since if want handle specific uri nfc tag in application (like defined in intent-filter) not delivered application, unless define record.

createapplicationrecord(string packagename);

this not available kind of compatibility bundle (i didn't find one), implementaion simple.

first add together ndefrecord want readable nfc device (remember uri can formatted/shortened uri_prefix_map)

ndefrecord[] nr = new ndefrecord[2]; nr[0] = new ndefrecord(ndefrecord.tnf_well_known, ndefrecord.rtd_uri, new byte[0], uribytes);

add aar in next place

static final byte[] rtd_android_app = "android.com:pkg".getbytes(); if (android.os.build.version.sdk_int >= android.os.build.version_codes.ice_cream_sandwich) nr[1] = ndefrecord.createapplicationrecord("your.package.name"); else nr[1] = new ndefrecord(ndefrecord.tnf_external_type, rtd_android_app, new byte[] {}, "your.package.name".getbytes());

you not need aar handle specific uri. aar method guarantee app started instead of app can handle same uri.

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
