Android应用程序蓝牙可见持续时间 [英] Android Application Bluetooth visibility duration

问题描述

有没有办法让我的应用程序可被发现的应用程序正在运行时间？我试图用

Is there a way to let my application be discoverable for a time the app is running? I tried to do this with

Intent discoverableIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 0);
startActivityForResult(discoverableIntent, DISC_DURATION);

如在Android开发者，但0的持续时间不工作，所以默认值120设置。有没有办法将其设置为可见的所有时间？

as shown on Android Developers, but the Duration of 0 doesn't work so the default value 120 is set. Is there a way to set it as visible all the time?

推荐答案

我来三个设备我的结论。

I come to the conclusion on three devices I have.

ANDROID v 4.3和更高版本：EXTRA_DISCOVERABLE_DURATION 0作品没有限制 ANDROIND V4.1版本：EXTRA_DISCOVERABLE_DURATION 0是最大1小时。必须手动更改为参数没有限制。

ANDROID v 4.3 and higher : EXTRA_DISCOVERABLE_DURATION 0 works no limit ANDROIND v 4.1 : EXTRA_DISCOVERABLE_DURATION 0 is max 1 hour. Have to change manually to no limit in parameters.
