PrivateUri Converturi (Uri uri) {InputStream is=NULL; Try{ is=getcontentresolver (). Openinputstream (URI); Bitmap Bitmap=Bitmapfactory.decodestream (IS);            Is.close (); returnSavebitmap (bitmap); } Catch(FileNotFoundException e) {e.printstacktrace (); return NULL; } Catch(IOException e) {e.printstacktrace (); return NULL; }    }

4. Save the picture and remember to add permission

1 PrivateUri Savebitmap (Bitmap BM) {2File TmpDir =NewFile (environment.getexternalstoragedirectory ()3+ "/xiaoxin");4         if(!tmpdir.exists ()) {5 Tmpdir.mkdir ();6         }7File img =NewFile (Tmpdir.getabsolutepath () + "Love.png");8         Try {9FileOutputStream fos =NewFileOutputStream (IMG);TenBm.compress (Bitmap.CompressFormat.PNG, 85, FOS); One Fos.flush (); A fos.close (); -Toast.maketext (mainactivity. This, "succeeded.", Toast.length_short). Show (); -             returnuri.fromfile (IMG); the}Catch(FileNotFoundException e) { -Toast.maketext (mainactivity. This, "failed.", Toast.length_short). Show (); - e.printstacktrace (); -             return NULL; +}Catch(IOException e) { - e.printstacktrace (); +Toast.maketext (mainactivity. This, "failed.", Toast.length_short). Show (); A             return NULL; at         } -  -}
