android - MediaPlayer setDataSource failed with status=0x80000000 for Ringtone set by filepath on 2.3.4 -

title says of it.

my application has been playing ringtones pointed uri content://media/internal/audio/media/387 or content://media/external/audio/media/1655 (for custom ringtones on sdcard believe) using both setdatasource(fileinfo) , setdatasource(mcontext, uri.parse(fileinfo)).

in each case have received logs information setdatasource failed.: status=0x80000000 exception on phones using android 4.x (different versions).

seeing error happens ringtones pointed content uri, not single files pointed path, have decided use paths ringtones fixed problem on above phones (while still using setdatasource(mcontext, uri.parse(fileinfo)) )

it has started problems on phones android 2.3.4-2.3.6 (not on mine 2.3.3 though):

• i have received few logs exception: setdatasource failed.: status=0x80000000 files paths /system/media/audio/ringtones/twirlaway.ogg

• i have received log mediaplayer.onerrorlistener.onerror(int what, int extra) method call what=1 , extra=-2147483648, which, know, suggest either file missing or corrupted. perform

  file file = new file(fileinfo); if (!file.exists()) 

check in such situation , returned file exist - corrupted then? highly unlikely music file in internal memory.

to sum up:

• works setdatasource("content://media/internal/audio/media/52")
• throws exception: setdatasource failed.: status=0x80000000 setdatasource(mcontext, "/system/media/audio/ringtones/twirlaway.ogg")

interestingly, first few lines of setdatasource(context context, uri uri, headers headers) method called setdatasource(context context, uri uri) (from grepcode source 2.3.4):

 string scheme = uri.getscheme();      if(scheme == null || scheme.equals("file")) {          setdatasource(uri.getpath());          return;      } 

so, after all, fails setdatasource("/system/media/audio/ringtones/twirlaway.ogg"). have taken paths ringtones uris using:

private static string getringtonepathfromcontenturi(context context,         uri contenturi) {      string[] proj = { mediastore.audio.media.data };     cursor ringtonecursor = context.getcontentresolver().query(contenturi,             proj, null, null, null);     ringtonecursor.movetofirst();     return ringtonecursor.getstring(ringtonecursor             .getcolumnindexorthrow(mediastore.audio.media.data)); } 

any ideas can causing error throwing? maybe issues caused lack of reading permissions? guess source code native setdatasource(string path) function lot, wasn't able find it.

answer lorne below helpful when dealing problem.

for else struggling it, here code have been using on 6 months errors not reported anymore.

fileinfo can both of below (examples):

/system/media/audio/alarms/walk_in_the_forest.ogg

content://media/internal/audio/media/20
