Can not locate the sdcard file(not hard code) in android 6.0

由 不打扰是莪最后的温柔 提交于 2019-12-13 23:41:58
问题 Since android 6.0, the sdcard path is no longer "/storage/sdcard1/", "/storage/sdcard-ext/" or something. The path depends on the phone instead. If I use Nexus 5x AVD, the path is "/storage/1D15-3A1B/". When I use Nexus 6p AVD, the path is "/storage/4679-1802/". So how can I dynamically write the sdcard path in program to locate the file in external sdcard? Thank you! 回答1: Have a look at getExternalFilesDirs() . 回答2: It seems that I found the solution. I'm using the access storage framework.

Flutter WebView Plugin - How To Handle Local Storage Variables

由 放肆的年华 提交于 2019-12-13 16:29:09
问题 Background: I am working on a mobile application in which I use a WebViewScaffold to load an online directory. This particular directory provides a guided tour on initial visit. Problem: Each time I navigate to the directory WebView, the tour starts from the beginning (which freezes the user until the tour is finished). How might I keep this from happening? When I open the directory in a browser, the status of the tour is saved in the browser's local storage variables. Is there a way to save

How to make swipe function on listview (react-native)?

由 坚强是说给别人听的谎言 提交于 2019-12-06 13:42:17
I have list of items. I am using ListView for it and I need to be able to delete any row by swiping left or right. Where can I start from here? If you prefer, follow this guide which uses React Native Swipeout . Otherwise, here's my SwipeList and SwipeListRow component. I partially use my library Cairn for styling, but it should be easily translated into a normal React Stylesheet if you care to do so: SwipeList.js import React from 'react'; import { Text, ListView } from 'react-native'; import styleContext from 'app/style'; const style = styleContext.extend({ listViewSection: { paddingVertical
