Process picture, method one, direct processing return Picture:
Comments:
1, the on-line has the explanation, the direct processing returns the picture is is compressed by the system, but oneself in the test process does not have the difference;
2, if users continue to retrieve pictures, the current BMP memory must be released, otherwise it will be an error! Bmp.recycle ().

The code is as follows

protected void Onactivityresult (int requestcode, int resultcode, Intent data) { Super.onactivityresult (Requestcode, ResultCode, data); if (ResultCode = = RESULT_OK) { Select picture Uri uri = Data.getdata (); Contentresolver CR = This.getcontentresolver (); try { if (BMP! = null)//If not released, continue to take pictures, will not have enough memory Bmp.recycle (); BMP = Bitmapfactory.decodestream (Cr.openinputstream (URI)); catch (FileNotFoundException e) { TODO auto-generated Catch block E.printstacktrace (); } System.out.println ("The BMP toString:" + BMP); Imagesv.setbmp (BMP); }else{ Toast.maketext (setimageactivity.this, "Please select the picture", Toast.length_short). Show (); } } protected void Onactivityresult (int requestcode, int resultcode, Intent data) { Super.onactivityresult (Requestcode, ResultCode, data); if (ResultCode = = RESULT_OK) { Select picture Uri uri = Data.getdata (); Contentresolver CR = This.getcontentresolver (); try { if (BMP! = null)//If not released, continue to take pictures, will not have enough memory Bmp.recycle (); BMP = Bitmapfactory.decodestream (Cr.openinputstream (URI)); catch (FileNotFoundException e) { TODO auto-generated Catch block E.printstacktrace (); } System.out.println ("The BMP toString:" + BMP); Imagesv.setbmp (BMP); }else{ Toast.maketext (setimageactivity.this, "Please select the picture", Toast.length_short).
