但它编译并运行为桌面应用程序，没有错误

更新：如果我发表评论import QtBluetooth 5.0，它会在我的设备上运行，但我正在尝试制作应用以使用我设备的蓝牙，所以我需要它

Answer 1

目前QtBluetooth不支持Android，所以这是预期的。

有关详细信息，请参阅documentation。

新的Qt蓝牙模块允许您检索有关本地蓝牙设备的信息，扫描和检索有关范围内设备的信息，将文件推送到设备并使用RFCOMM连接到它们。 Qt蓝牙模块目前仅支持Linux（在BlueZ 4.x上）和BlackBerry。

有关更多详细信息，请参阅今天的my other answer以获取更多详细信息。

希望这有帮助。
