问题描述
我试图将蓝牙可发现模式总是在的Android 4.0 。这应该是可能的4.0，使用以下命令：
I am trying to set the bluetooth discoverable mode to always on in Android 4.0. This should be possible with 4.0, with the command:
Intent enableBtIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
enableBtIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 0);
在执行此之后，我得到询问是否OK总是与discoverybility启动蓝牙的对话框。如果我preSS是蓝牙设置将显示0:00时，它不会倒计时。到目前为止，它看起来不错，但2分钟后蓝牙将再次变为unvisible模式（如previous设置为2分钟）。只有当previous设置总是在意图将工作（通过手动进入蓝牙设置中设置）。
After executing this I get a dialog that asks if it is OK to start bluetooth with discoverybility always on. If I press yes the bluetooth setting will show the time 0:00 and it will NOT countdown. So far it looks fine, but after 2 min the bluetooth will change to unvisible mode again (if the previous setting was 2 min). Only if the previous setting was always on (set by manually going into the bluetooth settings) the Intent will work.
有谁知道更多吗？这是一个bug或者是它是如何应该是什么？如果它不可能由code将设置更改为Always On？
Does anyone know more about this? Is this a bug or is it how it is supposed to be? Should it not be possible to change the setting to always on by code?
