Build.VERSION.SDK_INT >= Build.VERSION_CODES.N声明文件传输权限
AndroidManifest.xml声明权限provider统一格式
<provider
android:name="androidx.core.content.FileProvider"
<!--一般包名加.FileProvider(可以随便定义)-->
android:authorities="com.dev.apkshare.FileProvider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths" />
</provider>
res下创建xml目录后创建file_paths.xml配置文件
<?xml version="1.0" encoding="utf-8"?>
<paths>
<!--Android/data/包名/-->
<external-path path="Android/data/com.dev.apkshare(包名)/" name="files_root" />

有些会用上面方式拉起系统分享界面，这个会报下面问题导致无法添加各个分享应用
java.lang.SecurityException: Permission Denial: reading androidx.core.content.FileProvider uri content://com.dev.apkshare.FileProvider/./system/priv-app/DocumentsUI_royole/DocumentsUI_royole.apk from pid=17076, uid=1000 requires the provider be exported, or grantUriPermission()

解决方法：
直接使用shareIntent不要通过Intent.createChooser创建。
