params

问题 We have an app that works with all our supported Android phones "except Samsung Galaxy S5" . Our app uses the camera to take pictures at close range.

My ExtJs 3 code -> var store = new Ext.data.JsonStore({ root: 'Data', baseParams: { StartDate: '', EndDate: ''' },//baseParams proxy: new Ext.data
