Here,In WebChromeClient:

public class MyWebChromeClient extends WebChromeClient{

        return true;

    }

    // openFileChooser for Android 3.0+
    public void openFileChooser(ValueCallback<Uri> uploadMsg, String acceptType) {

        mUploadMessage = uploadMsg;

        // Create AndroidExampleFolder at sdcard

    //openFileChooser for other Android versions
    public void openFileChooser(ValueCallback<Uri> uploadMsg,

}


For Image:
private File createImageFile() throws IOException {
    // Create an image file name
        String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss").format(new Date());
       String imageFileName = "JPEG_" + timeStamp + "_";


            java.io.File xmlFile = new java.io.File((getBaseContext()
            .getApplicationContext().getFileStreamPath("FileName.xml")
            .getPath()));
    return xmlFile;
}

This is helpful for me. But, Camera is not working for Nexus 5. For this, I use the following code at onActivity method :

if (resultCode == Activity.RESULT_OK) {
        if (data == null || data.getDataString() == null) {
            // If there is not data, then we may have taken a photo
            if (mCameraPhotoPath != null) {
                results = new Uri[]{Uri.parse(mCameraPhotoPath)};
            }
        } else {
            String dataString = data.getDataString();
            if (dataString != null) {
                results = new Uri[]{Uri.parse(dataString)};
            }
        }
    }

I add this : if (data == null || data.getDataString() == null) {...}
