Canvas: trying to use a recycled bitmap android - onSaveInstanceState -

i'm using camera via intent snap image , save imageview. intent camera in landscape mode , activity returns in portrait mode. activity changes orientation , reloads new activty. i'm trying save image in imageview. while returning activity page disappears once activity in portrait mode. when added onsaveinstancestate method crashes error:

  canvas: trying use recycled bitmap android 

i have added code below:

 public void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.main_page);     imageview = (imageview) findviewbyid(r.id.result);     if(savedinstancestate != null){         bitmap photo = savedinstancestate.getparcelable("savedimage");         imageview.setimagebitmap(photo);         }    } 

i have saved image follows

protected void onsaveinstancestate(bundle icicle){       super.onsaveinstancestate(icicle);       imageview.builddrawingcache();       parcelable bm = imageview.getdrawingcache();       icicle.putparcelable("savedimage",bm);   } 

the canvas error because bitmap isn't there more after orientation change. also, parcelable you're setting in onsavedinstancestate() may not there. think of way: views logically "higher level" intents , called-back results.

you can save image file system camera before populate view it.

so, more housekeeping. in several production / released apps ... , there might better way (?)

1. define file (path & name) ahead of time before firing camera intent.
2. fire camera, grab bitmap image via intent->data parm passed onactivityresult()
3. still in onactivityresult, plop bitmap view ,
4. then write known file (and close it).

note between step 2 & 3, compress bitmap save space.

to deal reorientation, have routine in onstart or onresume - fired after oncreate():

1. try open known file

2. if fails or has no data:

   then use default image (could res jpg),

   else file , image good: put image file imageview

3. close file.

this way, you've got something put in there, no matter happens. of time, works expected :)) ( says after breaking 4 people's wrists flipping android phones @ high speeds lol )

btw - problem can further compounded because camera hardware differs across vendors. devices stay oriented same way before, during, , after camera processing. others, (or ?) newer samsungs, flip camera orientation no matter (unless drop hardware - way way more complex).

is device you're having problems samsung ? - aware can cause more headaches.
