android - Native crash in unknown unknown -


i have app entirely written in java - no native code whatsoever - , i've twice had crash report on developer console "native crash in unknown unknown". have no idea start locating source of problem. searching has revealed type of crash in case of android bugs, ndk usage or buggy third party libraries.

for it's worth, here 1 of logs:

any suggestions next steps? have own logfile it's nothing granular enough have tracked this.

the fourth scenario buggy roms, whether roms stock roms manufacturer or rom mods (e.g., cyanogenmod). once-in-a-blue-moon sorts of crashes come rom issues, otherwise run them more often.

any suggestions next steps?

for couple of users, wouldn't worry.

otherwise, build fingerprint give idea of environment working with. in case, samsung/m0xx appear samsung gt-i9300, 1 of "galaxy s3" variants. if can hands on 1 of -- whether via outright purchase, online testing service, or borrowing friend -- see if can reproduce crash , narrow down in code crash coming from. if can that, perhaps can come workaround either fine devices, or @ least gets past crash on one.
