在工作中遇到一個(gè)問(wèn)題：在藍(lán)牙連接時(shí)需要跳過(guò)pin驗(yàn)證男图，當(dāng)時(shí)找了很多博客呆万，最后基本解決（有些room會(huì)出問(wèn)題）肌蜻，因?yàn)樵诤?jiǎn)書(shū)中沒(méi)有搜到該問(wèn)題的解決方案所以就寫(xiě)下這篇博客。
基本解決思路：
1恕刘、使用反射調(diào)用BluetoothDevice的setPin方法缤谎。
2、接收系統(tǒng)的彈出的驗(yàn)證pin碼的彈框的廣播褐着，及時(shí)終止坷澡。
1、注冊(cè)廣播
<receiver android:name=".BluetoothConnectActivityReceiver" >
<intent-filter android:priority="1000">
<action android:name="android.bluetooth.device.action.PAIRING_REQUEST" />
</intent-filter>
</receiver>
public class BluetoothConnectActivityReceiver extends BroadcastReceiver {
@Override
public void onReceive(Context context, Intent intent) {
if ("android.bluetooth.device.action.PAIRING_REQUEST".equals(intent.getAction())) {
BluetoothDevice mBluetoothDevice = intent.getParcelableExtra(BluetoothDevice.EXTRA_DEVICE);
try {
//(三星)4.3版本測(cè)試手機(jī)還是會(huì)彈出用戶(hù)交互頁(yè)面(閃一下)含蓉，如果不注釋掉下面這句頁(yè)面不會(huì)取消但可以配對(duì)成功频敛。(中興，魅族4(Flyme 6))5.1版本手機(jī)兩中情況下都正常
//ClsUtils.setPairingConfirmation(mBluetoothDevice.getClass(), mBluetoothDevice, true);
abortBroadcast();//如果沒(méi)有將廣播終止馅扣，則會(huì)出現(xiàn)一個(gè)一閃而過(guò)的配對(duì)框斟赚。
//3.調(diào)用setPin方法進(jìn)行配對(duì)...
boolean ret = ClsUtils.setPin(mBluetoothDevice.getClass(), mBluetoothDevice, "你需要設(shè)置的PIN碼");
} catch (Exception e) {
e.printStackTrace();
}
}
}
}
最后把ClsUtils貼出來(lái)，網(wǎng)上這個(gè)類(lèi)應(yīng)該是很多的差油。我已開(kāi)始也用到了拗军，因?yàn)闆](méi)有監(jiān)聽(tīng)上面的廣播所以失敗了任洞。

藍(lán)牙的連接，斷開(kāi)的代碼我就不貼出來(lái)了发侵，記得要加上必要的權(quán)限交掏。
Android 6.0 一定要加上模糊定位的權(quán)限！
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
向開(kāi)源者致敬!
