如何从appcenter中拉取apk文件并安装到android设备上，而不是手动下载并存储在本地并安装

import okhttp3.OkHttpClient;
import okhttp3.Request;
import okhttp3.Response;

// ...

OkHttpClient client = new OkHttpClient();
String appCenterApiUrl = "https://api.appcenter.ms/v0.1/apps/{owner_name}/{app_name}/branches/{branch_name}/builds/latest";
String ownerName = "your_owner_name";
String appName = "your_app_name";
String branchName = "your_branch_name";

// 构建API请求URL
String apiUrl = appCenterApiUrl
    .replace("{owner_name}", ownerName)
    .replace("{app_name}", appName)
    .replace("{branch_name}", branchName);

// 创建API请求
Request request = new Request.Builder()
    .url(apiUrl)
    .build();

try {
    // 发送API请求
    Response response = client.newCall(request).execute();
    String responseBody = response.body().string();

    // 解析API响应，获取APK下载URL
    // 这里需要根据AppCenter API的响应结构进行解析
    // 例如：JSONObject jsonObject = new JSONObject(responseBody);
    // String downloadUrl = jsonObject.getString("download_url");

    // 使用OkHttp下载APK文件
    Request apkRequest = new Request.Builder()
        .url(downloadUrl)
        .build();

    Response apkResponse = client.newCall(apkRequest).execute();
    InputStream apkInputStream = apkResponse.body().byteStream();

    // 将APK文件保存到本地存储，例如SD卡或应用私有目录
    File apkFile = new File(getExternalFilesDir(null), "app.apk");
    FileOutputStream apkOutputStream = new FileOutputStream(apkFile);

    byte[] buffer = new byte[4096];
    int bytesRead;
    while ((bytesRead = apkInputStream.read(buffer)) != -1) {
        apkOutputStream.write(buffer, 0, bytesRead);
    }

    // 关闭流
    apkInputStream.close();
    apkOutputStream.close();

    // 使用PackageManager安装APK文件
    Intent installIntent = new Intent(Intent.ACTION_INSTALL_PACKAGE);
    installIntent.setData(Uri.fromFile(apkFile));
    installIntent.setFlags(Intent.FLAG_GRANT_READ_URI_PERMISSION);
    startActivity(installIntent);
} catch (IOException e) {
    e.printStackTrace();
}
