oppo 版本11 下载后解析程序包出现问题

[renhuan]

原因是没有打开 canRequestPackageInstalls权限，代码如下

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                        mActivity?.let { it ->
                            if (!it.packageManager.canRequestPackageInstalls()) {
                                val packageURI = Uri.parse("package:" + it.packageName)
                                val intent = Intent(Settings.ACTION_MANAGE_UNKNOWN_APP_SOURCES, packageURI)
                                it.startActivityForResult(intent, 50000)
                            } else {
                                showVersionDialog(this)
                            }
                        }
                    }
