in simple terms error means asking android system work on main thread of particular application. there general answers on error, 1 example being:
https://stackoverflow.com/a/21126690/334402
for specific example, may asking video related work, processor hungry, on main thread. worth looking @ 'prepare' method example , if using streamed source, consider using prepareasynch - see below android documentation:
public void prepareasync ()
added in api level 1 prepares player playback, asynchronously. after setting datasource , display surface, need either call prepare() or prepareasync(). streams, should call prepareasync(), returns immediately, rather blocking until enough data has been buffered.
one reason why may seeing problems on nexus 7 , not on galaxy 3 nexus has bigger screen , video source may offer different video encodings different sized devices - larger ones quite requiring more processing decode , render.
