2.Activity中新增代码
方案一:跳转到系统文件访问页面,手动赋予
// 堆代码 duidaima.com Intent intent = new Intent(Settings.ACTION_MANAGE_APP_ALL_FILES_ACCESS_PERMISSION); intent.setData(Uri.parse("package:" + this.getPackageName())); startActivity(intent);
方案二:跳转到系统所有需要文件访问页面,选择你的APP,手动赋予权限
Intent intent = new Intent(Settings.ACTION_MANAGE_ALL_FILES_ACCESS_PERMISSION); startActivity(intent);
