Android权限适配方案（API 4+)

由于Android6.0 加入了权限判断，如果你的项目buildToolsVersion是23+的话而没有做权限适配，那么程序就会崩溃；本文介绍的是笔者的权限适配的方案

首先我用的工具是github上别人开源的工具我用Java重写的 那个项目是用kotlin写的，感谢hotchemi (为什么去重写呢，因为小米与与官方的权限判断有点不同，然后向hotchemi大神请求加上小米手机的特别判断，但是人家不同意啊，因为他是日本的没有小米手机无法测试什么的) 
地址：https://github.com/a1018875550/PermissionDispatcher 
这是个很好的权限适配工具，支持到API 4+;在大部分手机上管用，并且我加入了小米手机权限的判断但只在6.0以上的小米手机管用

在此说明一点这个工具必须在Android Studio 2.0+版本使用，以前的版本使用会报莫名的bug，使用很蛋疼

导入方法： 
在项目的buid.gradle文件里添加

<code class="hljs matlab has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;">buildscript <span class="hljs-cell" style="box-sizing: border-box;">{  dependencies {    classpath <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'com.neenbedankt.gradle.plugins:android-apt:1.8'</span>  }</span>}</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li></ul>

然后在Module的build.gradle文件中添加依赖和属性配置

<code class="hljs matlab has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;">apply plugin: <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'android-apt'</span>dependencies <span class="hljs-cell" style="box-sizing: border-box;">{   compile <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'org.jokar:permissiondispatcher:latest.version'</span>  apt <span class="hljs-string" style="color: rgb(0, 136, 0); box-sizing: border-box;">'org.jokar:permissiondispatcher-processor:latest.version'</span>}</span></code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul>

这里的latest.version也可以写成具体的版本号，具体的版本号地址在这里查看

ok导入好了，要介绍这个工具怎么使用了， 
首先介绍这个工具有哪些东西

• @RuntimePermissions 是必须的注册当前activity或fragment
• @NeedsPermission 是必须要有的，在需要权限的方法上添加
• @OnShowRationale 注释一个方法解释为什么需要这个(个)权限并提示用户判断是否允许
• @OnPermissionDenied 当权限被拒绝时调用
• @OnNeverAskAgain 当用户勾选了不再提示时调用

这就是这个权限工具的所有功能

在acttivty/fragment 上添加@RuntimePermissions然后在需要权限的方法上添加@NeedsPermission，其他的根据需求添加;后一定要先点击Rebuild project

等build好后在onRequestPermissionsResult方法添加

<code class="hljs java has-numbering" style="display: block; padding: 0px; background: transparent; color: inherit; box-sizing: border-box; font-family: "Source Code Pro", monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal;"><span class="hljs-annotation" style="color: rgb(155, 133, 157); box-sizing: border-box;">@Override</span><span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">public</span> <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">void</span> <span class="hljs-title" style="box-sizing: border-box;">onRequestPermissionsResult</span>(<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">int</span> requestCode, String[] permissions, <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">int</span>[] grantResults) {    <span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">super</span>.onRequestPermissionsResult(requestCode, permissions, grantResults);    <span class="hljs-comment" style="color: rgb(136, 0, 0); box-sizing: border-box;">// NOTE: delegate the permission handling to generated method</span>    MainActivityPermissionsDispatcher.onRequestPermissionsResult(<span class="hljs-keyword" style="color: rgb(0, 0, 136); box-sizing: border-box;">this</span>, requestCode, grantResults);}</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; background-color: rgb(238, 238, 238); top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right: 1px solid rgb(221, 221, 221); list-style: none; text-align: right;"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li></ul>

这里MainActivityPermissionsDispatcher 的命名规则是根据当前activity/fragent +”PermissionsDispatcher” ;所以在自己写的时候不要死板硬套写MainActivityPermissionsDispatcher

然后这就注册好了，下面是怎么调用那个权限方法
