安装Apk时报错FileUriExposedException
1、AndroidManifest.xml写入
<provider
android:name="android.support.v4.content.FileProvider"
android:authorities="你的包名.fileprovider"
android:exported="false"
android:grantUriPermissions="true">
<meta-data
android:name="android.support.FILE_PROVIDER_PATHS"
android:resource="@xml/file_paths"/>
</provider>
2、声明res/xml/file_paths
3、file_paths.xml添加内容
<?xml version="1.0" encoding="utf-8"?>
<paths>
<external-path path="Android/data/你的包名/" name="files_root" />
<external-path path="." name="external_storage_root" />
</paths>
4、启动安装Intent
public static void installApk(Context context, String fileName) {
Intent intent = new Intent(Intent.ACTION_VIEW);
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
intent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
Uri contentUri = FileProvider.getUriForFile(context, "你的包名.fileprovider", new File(fileName));
intent.setDataAndType(contentUri, "application/vnd.android.package-archive");
} else {
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setDataAndType(Uri.parse("file://" + fileName),
"application/vnd.android.package-archive");
}
context.startActivity(intent);
}
