contentprovide例子(一)
- ContentProvider示例一：联系人数据库在Android开发中，我们经常会需要访问设备的联系人信息。
这时就可以使用ContentProvider来提供联系人数据库的访问功能。
首先，我们需要在文件中声明READ_CONTACTS权限。
然后，我们可以通过ContentResolver类来获取联系人信息，实现对联系人数据库的访问。
我们可以通过以下步骤来实现对联系人数据库的访问：1. 首先，我们需要创建一个继承自ContentProvider的子类，例如ContactsProvider。
在ContactsProvider中，我们需要重写query、insert、update和delete方法，这些方法分别对应了查询、插入、更新和删除操作。
2. 在query方法中，我们可以构建合适的SQL语句，然后通过ContentResolver的query方法来执行查询操作，从而获取联系人信息。
3. 在insert方法中，我们可以通过ContentResolver的insert方法来执行插入操作，向联系人数据库中添加新的联系人信息。
4. 在update方法中，我们可以通过ContentResolver的update方法来执行更新操作，更新联系人数据库中的联系人信息。
5. 在delete方法中，我们可以通过ContentResolver的delete方法来执行删除操作，从联系人数据库中删除指定的联系人信息。
用中获取、添加、更新和删除联系人信息。
- ContentProvider示例二：媒体文件访问除了联系人数据库之外，我们还可以使用ContentProvider来实现对媒体文件的访问。
例如，我们可以访问设备上的音乐文件、视频文件和图片文件。
通过ContentProvider，我们可以实现对媒体文件的查询、插入、更新和删除操作。
要实现对媒体文件的访问功能，我们可以按照以下步骤进行操作：1. 首先，我们需要创建一个继承自ContentProvider的子类，例如MediaProvider。

The backpanel of the floor unit can be kept - only a cut-out for the air outlet is needed (position and size can be taken from the installation instructions).- - The "Plug 'n Play" starter kit HEZ9VRUD0 for unducted recirculation requires a vertical aperture of min. 25mm behind thebackpanel of the furniture. Suggested for ideal performance are 50mm.- - The minimum worktop thickness is 16mm for top mounted and flush installed appliances with the standard installation system. Installation in even thinner worktops is also possible with the spare part: content 626792.- - The overall appliance weight is 26kg - the bearing capacity and stability, in the case of very thin worktops in particular, must be supported using suitable substructures. The overall appliance weight and the worktop manufacturer's structural integrity specifications are to be taken into account.- - For partly ducted and unducted recirculation extraction installations, a return-flow aperture of ≥400cm² is to be respected in the plinth area. The aperture can be realized via outlet grids, lamella grids or subtly shortened plinths depending on the assortment of the kitchen furniture manufacturer.- - The air outlet on the backside of the appliance can directly be accessed with a male flat duct element (DN 150).- - The pressuredrop resistant blower allows longer and more complex ductings up to 8m with three 90° elbows while keeping sufficient performance.- - When installing a ventilation hood with ducted extraction and a chimney-vented fireplace, the power supply line of the appliance needs a suitable safety switch. This is not required for configurations in recirculated extraction.- - In ducted extraction configuration a one-way flap (or backflow trap) with a maximum opening pressure of 65Pa should be installed.Series 4, Induction hob with integrated ventilation system, 80 cm, surface mount without framePIE811B15E。
AndroidN7.0中报错：a...
AndroidN7.0中报错：a...发现问题最近在Android N 上安装Apk时报错：android.os.FileUriExposedException: file:///storage/emulated/0/Download/appName-2.3.0.apk exposed beyond app through Intent.getData()，通过查找相关的资料终于找到了解决的⽅法，下⾯分享给⼤家，话不多说了，来⼀起看看详细的介绍吧。
解决⽅法1、在AndroidManifest.xml中添加如下代码<provider android:name="android.support.v4.content.FileProvider"android:authorities="app的包名.fileProvider"android:grantUriPermissions="true"android:exported="false"><meta-dataandroid:name="android.support.FILE_PROVIDER_PATHS"android:resource="@xml/file_paths" /></provider>注意：authorities：app的包名.fileProvidergrantUriPermissions：必须是true，表⽰授予 URI 临时访问权限exported：必须是falseresource：中的@xml/file_paths是我们接下来要添加的⽂件2、在res⽬录下新建⼀个xml⽂件夹，并且新建⼀个file_paths的xml⽂件（如下图）3、打开file_paths.xml⽂件添加如下内容<?xml version="1.0" encoding="utf-8"?><paths><external-path path="Android/data/app的包名/" name="files_root" /><external-path path="." name="external_storage_root" /></paths>path：需要临时授权访问的路径（.代表所有路径）name：就是你给这个访问路径起个名字4、修改代码适配Android NIntent intent = new Intent(Intent.ACTION_VIEW);//判断是否是AndroidN以及更⾼的版本if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);Uri contentUri = FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".fileProvider", apkFile);intent.setDataAndType(contentUri, "application/vnd.android.package-archive");} else {intent.setDataAndType(Uri.fromFile(apkFile), "application/vnd.android.package-archive");intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);}startActivity(intent);1、⾸先我们对Android N及以上做判断；2、然后添加flags，表明我们要被授予什么样的临时权限3、以前我们直接 Uri.fromFile(apkFile)构建出⼀个Uri,现在我们使⽤FileProvider.getUriForFile(context, BuildConfig.APPLICATION_ID + ".fileProvider", apkFile);4、BuildConfig.APPLICATION_ID直接是应⽤的包名总结以上就是这篇⽂章的全部内容了，希望本⽂的内容对⼤家的学习或者⼯作具有⼀定的参考学习价值，如果有疑问⼤家可以留⾔交流，谢谢⼤家对的⽀持。

ContentProvider的使用
知识解析
ContentProvider
什么是Content provider？它是Android应用程序的四大组成部分之一，是Android中的跨应用访问数据机制。
为何需要content provider？ Android中每一个app的资源是私有的，其他app不可访问它的数据，但可以通过content
provider和其他app共享私有数据。
ContentProvider通过URI来向其他的app提供访问路径。
URI的组成如下图所示。
A：标准前缀，用来说明一个Content
Provider控制这些数据，对于自定义ContentProvider来说，就是“content:/ /”，我们无法改变；
B：URI的标识，它定义了是哪个Content
Provider提供这些数据。
对于第三方应用程序，为了保证URI标识的唯一性，它必须是一个完整的、小写的包名+类名。
这个标识在<provider> 元素的authorities属性中说明：
<provider name=”.TransportationProvider”
authorities=”com.example.myproject.transportationprovi
der” . . . >
C：路径，Content
Provider使用这些路径来确定当前需要的是什么类型的数据，URI中可能不包括路径，也可能包括多层；通常这里对应的是某个表或者视图的名字
D：如果URI中包含，表示需要获取的记录的ID；如果没有ID，就表示返回全部；
由于URI通常比较长，而且有时候容易出错，且难以理解。
所以，对于Android 的内置App如通讯录等，定义了一些辅助类，并且定义了一些常量来代替这些长字符串，例如：ContactsContract.Contacts.CONTENT_URI
ContentResolver
ContentProvider可将Content分享至不同的应用程序之中，而ContentRes olver则是一个标准的方式来取得ContentProvider所提供的数据，也是用来修改数据的方法，但若牵涉到写入或修改数据的话，则要看目标的ContentProvi der是否允许用户对数据做存取的操作，若无此权限，则ContentResolver方法会失败。
ContentProvider通常会使用URI的方式来当作分享数据的依据，故在ContentR esolver要读取某一ContentProvider数据时则必须将要读取的URI当成参数来使用。
ContentResolver使用query()来对指定URI的ContentProvider进行查询，它的参数包括下表中列出的各项。
和SQLiteDatabase的query()基本类似，除了这里提供的是一个uri而不是表名。
它也包括对数据进行其他增、删、改的操作方法，如下表。
可以通过Context上的getContentResolver()来获得一个ContentResolver 对象。
Android自带的应用例如通讯录，也通过ContentProvider向外提供了数据访问接口，我们可以通过ContentREsolver访问它。
下面我们看一下和通讯录相关的ContentProvider信息：
联系人信息URI： ContactsContract.Contacts.CONTENT_URI
电话信息：
monDataKinds.Phone.CONTENT_URI：其中，ContactsC monDataKinds.Phone.CONTACT_ID是ContactsContract.Contacts. _ID的外键
邮件信息： monDataKinds.Email
聊天工具信息： monDataKinds.Im
网站： monDataKinds.Website
职业素质
ContentProvider：为存储和获取数据提供统一的接口。
可以在不同的应用程序之间共享数据。
Android已经为常见的一些数据提供了默认的ContentPr ovider。
