Andrews solve webview does not support the input type = file problem

Front page in a word, <the INPUT of the type = "File" the Accept = "Image / *; Camera Capture =">,
IOS phone, you can call directly from the camera and photo albums;
Android phones are not, part of the browser no problem;


to solve the problem, directly on the code;

Pro-test, Huawei, millet, Samsung, 360, Meizu can call a normal camera and photo albums
