问题描述
我想定期检查是否在任何 Android 设备上启用了蓝牙.我可以使用 BroadcastReceiver 捕获任何意图,或者有其他方法可以做到吗?
I would like to check if bluetooth is enabled on any Android device periodically. Is there any intents that I could catch using BroadcastReceiver to do so, or is there other ways to do it?
推荐答案
给你:
BluetoothAdapter mBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
if (mBluetoothAdapter == null) {
// Device does not support Bluetooth
} else if (!mBluetoothAdapter.isEnabled()) {
// Bluetooth is not enabled :)
} else {
// Bluetooth is enabled
}
使用 uses-permission
<uses-permission android:name="android.permission.BLUETOOTH" android:required="false" />
