原因：

Android N 上 安装Apk时报错：android.os.FileUriExposedException: file:///sdcard/update/wiiwork.apk exposed beyond app through Intent.getData()

解决办法：

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-data android:name="android.support.FILE_PROVIDER_PATHS" android:resource="@xml/file_paths" /> </provider>注意： authorities：app的包名.fileProvider grantUriPermissions：必须是true，表示授予 URI 临时访问权限 exported：必须是false resource：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 N Intent 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
