Qfile Pro (Android)
Root Cause
To conserve battery and optimize system resources, Android (especially Android 15 and above) implements strict background execution policies. If an app runs in the background for an extended period without user interaction, ranging from hours to days, at some point the system may pause the app to save power. If Qfile Pro is transferring files in the background, it may be paused by the system.
Background services may also be stopped by the system to save power if the service runs for an extended period—typically 6 hours, though this duration may vary depending on the device manufacturer. Qfile Pro runs a background service to detect new files and execute upload tasks. If the system stops the Qfile Pro background service, Qfile becomes unable to detect new files and perform upload tasks in the background.
Solution
While Qfile Pro has been optimized to meet Android's system requirements, the app cannot prevent the system from stopping background activities and services to conserve device power. If you notice that Qfile Pro is not detecting or uploading new files, you need to restart Qfile Pro.
Restarting Qfile Pro (Qfile Pro version 4.5.2 and later)
To restart Qfile Pro, simply open the app. After opening the app, the Qfile Pro background service will run normally and Qfile Pro will be able to detect new files and transfer files in the background.
Restarting Qfile Pro (Qfile Pro version 4.5.1 and earlier)
Tip
If you are running Qfile Pro version 4.5.1 or earlier, it is recommended to update Qfile Pro to the latest version.
To restart Qfile Pro, follow these steps:
- Open Android System Settings.
- Go to Apps.
- Find Qfile Pro and tap it.
App settings for Qfile Pro opens. - Tap Force Stop.
The Qfile Pro app and background services are stopped. This may take several seconds. - Go to the Android Home screen and open Qfile Pro again by tapping on the app icon.
After opening the app, the Qfile Pro background service will run normally and Qfile Pro will be able to detect new files and transfer files in the background.

Qfile Pro（Android）
根本原因
为了节省电池和优化系统资源，Android（尤其是 Android 15 及以上版本）实施了严格的后台执行策略。如果应用程序在没有用户交互的情况下长时间在后台运行，从几个小时到几天不等，系统可能会在某个时候暂停应用程序以节省电量。如果 Qfile Pro 在后台传输文件，可能会被系统暂停。
后台服务也可能会被系统停止以节省电量，如果服务运行时间过长——通常为 6 小时，尽管此持续时间可能因设备制造商而异。Qfile Pro 运行一个后台服务以检测新文件并执行上传任务。如果系统停止 Qfile Pro 后台服务，Qfile 将无法在后台检测新文件并执行上传任务。
解决方案
虽然 Qfile Pro 已优化以满足 Android 的系统要求，但应用程序无法阻止系统停止后台活动和服务以节省设备电量。如果您发现 Qfile Pro 未检测到或上传新文件，您需要重新启动 Qfile Pro。
重新启动 Qfile Pro（Qfile Pro 版本 4.5.2 及更高版本）
要重新启动 Qfile Pro，只需打开应用程序。打开应用程序后，Qfile Pro 后台服务将正常运行，Qfile Pro 将能够在后台检测新文件并传输文件。
重新启动 Qfile Pro（Qfile Pro 版本 4.5.1 及更早版本）
提示
如果您运行的是 Qfile Pro 版本 4.5.1 或更早版本，建议更新到 Qfile Pro 的全新版本。
要重新启动 Qfile Pro，请按照以下步骤操作：
- 打开 Android 系统设置。
- 进入 应用程序。
- 找到Qfile Pro并点击它。
打开 Qfile Pro 的应用设置。 - 点击强制停止。
Qfile Pro 应用和后台服务将被停止。这可能需要几秒钟。 - 返回 Android 主屏幕，再次点击应用图标打开Qfile Pro。
打开应用后，Qfile Pro 后台服务将正常运行，并且 Qfile Pro 能够在后台检测新文件并传输文件。
