Android Things APP版本更新解决方案

AndroidThings中如果使用传统的Intent来安装APK，你将永远安装不上

常见的应用内APK安装方法有以下两种方法

1.Intent安装APK的方法如下:

Intent intent = new Intent(Intent.ACTION_VIEW); intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); intent.addFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION); Uri contentUri = FileProvider.getUriForFile(this, BuildConfig.APPLICATION_ID + ".fileProvider", new File(path + "app-debug.apk")); intent.setDataAndType(contentUri, "application/vnd.android.package-archive"); startActivity(intent);

同时添加权限:

2.通过install命令来安装

命令如下:

pm install -i 当前包名 --user 0 XX.apk

运行方法:

Runtime.getRuntime().exec("")

注意：以上两种方法在android 手机中没有问题，但截止目前在Android Things 1.0.1中是行不通的

为了能在Android Things系统中更新APP，故经过不断的探索发现，最终采用插件化的方案来解决此问题

经过评估测试，最终发现360出品的RePlugin框架满足我们的需求

在RePlugin壳子中，必须申请完所有权限，因为壳子是不会更新的。我整理了所有的权限，在下面列出来

但是，光这些还不够，还需要解决两个坑

1.关于FileProvider的问题

我们需要提前在RePlugin中申请注册，Replugin是不会动态申请FileProvider

所以，需要在宿主程序中添加:

<br/><provider<br/> android:name="android.support.v4.content.FileProvider"<br/> android:authorities="宿主包名.fileProvider"<br/> android:exported="false"<br/> android:grantUriPermissions="true"><br/> <meta-data<br/> android:name="android.support.FILE_PROVIDER_PATHS"<br/> android:resource="@xml/file_paths" /><br/></provider><br/>

注意一点：此处填写宿主包名，当我们在插件中使用context.getPackageName()的时候，拿到的是宿主包名

2.在Android Things中APP默认是横屏，但当我们加载打开插件时，会发现APP被强制改为了竖屏

在这里，尝试反编译宿主APK，打开AndroidManifest文件后，发现screenOrientation的值为1，故RePlugin框架默认是将所有的Activity坑位默认设置的portrait竖屏

<br/><activity<br/> android:theme="@ref/0x01030006"<br/> android:name="com.xx.a.ActivityP2NRNTS1"<br/> android:exported="false"<br/> android:process=":p2"<br/> android:screenOrientation="1"<br/> android:configChanges="0x4b0" /><br/>

解决方案如下，修改RePlugin源码，找到replugin-host-gradle源码，修改ComponentsGenerator类，添加oriL变量，然后将所有的oriV改为oriL
