要解决Android下载管理器不立即下载的问题,可以使用以下代码示例来设置下载延迟或禁止下载特定URL:
DownloadManager.Request request = new DownloadManager.Request(Uri.parse("your_url"));
request.setAllowedNetworkTypes(DownloadManager.Request.NETWORK_WIFI); // 设置仅在Wi-Fi网络下下载
request.setAllowedOverRoaming(false); // 设置禁止在漫游状态下下载
// 设置下载延迟
request.setAllowedOverMetered(false); // 设置禁止在计量网络下下载
request.setRequiresCharging(true); // 设置仅在充电状态下下载
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_VISIBLE_NOTIFY_COMPLETED); // 设置下载完成后显示通知
DownloadManager downloadManager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
long downloadId = downloadManager.enqueue(request);
DownloadManager.Request request = new DownloadManager.Request(Uri.parse("your_url"));
// 设置禁止下载特定URL
request.setNotificationVisibility(DownloadManager.Request.VISIBILITY_HIDDEN); // 设置隐藏下载通知
request.setVisibleInDownloadsUi(false); // 设置隐藏下载界面
DownloadManager downloadManager = (DownloadManager) getSystemService(Context.DOWNLOAD_SERVICE);
long downloadId = downloadManager.enqueue(request);
注意:在使用上述代码示例时,需要将"your_url"替换为实际的下载URL。另外,还需要在AndroidManifest.xml文件中添加相应的权限:
