Android使用IntentService进行apk更新示例代码

public static class MyBroadcastReceiver extends BroadcastReceiver {
    @Override
    public void onReceive(Context context, Intent intent) {
      switch (intent.getAction()) {
        case ACTION_TYPE_PREPARE:
          if (downloadCallback != null) {
            downloadCallback.onPrepare();
          }
          break;
        case ACTION_TYPE_PROGRESS:
          int progress = intent.getIntExtra("progress", 0);
//          Log.d("progress", "|- " + progress + " -|");
          if (downloadCallback != null) {
            downloadCallback.onProgress(progress);
          }
          break;
        case ACTION_TYPE_COMPLETE:
          String file_path = intent.getStringExtra("file_path");
          if (!TextUtils.isEmpty(file_path)) {
            File file = new File(file_path);
            if (file.exists()) {
              if (downloadCallback != null) {
                downloadCallback.onComplete(file);
              }
            }
          }
          break;
        case ACTION_TYPE_FAIL:
          String error = intent.getStringExtra("error");
          if (downloadCallback != null) {
            downloadCallback.onFail(error + "");
          }
          break;
      }
    }

@Override

    super.onCreate();

  // 在下载进度刷新的地方进行回调

//初始化文件下载管理类
FileDownloaderManager.init(context)
// 注册下载进度监听，并开启广播接收

    })
//开始下载
FileDownloaderManager.download(url)

FileDownloaderManager.unbinder()
