} , here savemyimage method:

 public static void savemyimage( imageview imageview , context context , string imagename ) {      try {        bitmap bmimg = bitmap.createbitmap( imageview.getdrawingcache() ) ;         imageview.setdrawingcacheenabled( false ) ;         imageview.destroydrawingcache();         string fullimagepath = android.os.environment.getexternalstoragedirectory().tostring() + "/" + context.getstring( r.string.app_name ) ;         file filename ;         file file = new file( fullimagepath ) ;         if ( !file.exists() )             file.mkdirs() ;         filename = new file( file.getabsolutepath() + "/" + imagename + ".jpg" ) ;         fileoutputstream out = new fileoutputstream( filename ) ;         bmimg.compress( bitmap.compressformat.png , 90 , out ) ;         out.flush() ;         out.close() ;          contentvalues image = getimagecontent( filename , context ) ;         uri result = context.getcontentresolver().insert( mediastore.images.media.external_content_uri , image ) ;         toast.maketext( context , "file saved in  " + filename , toast.length_long ).show() ;         trace( "file saved in  " + filename ) ;         } catch ( exception e ) {         e.printstacktrace() ;     }  }
