我正在开发用于 ble 通信的 android 应用程序。

我的问题是为什么这个函数

public BluetoothGatt connectGatt(Context context, boolean autoConnect,BluetoothGattCallback callback, int transport)

需要Context作为参数，我挖掘了函数，发现它没有在任何地方使用它，正如你在这里看到的：

public BluetoothGatt connectGatt(Context context, boolean autoConnect,
                                     BluetoothGattCallback callback, int transport,
                                     boolean opportunistic, int phy, Handler handler) {
        if (callback == null)
            throw new NullPointerException("callback is null");

        // TODO(Bluetooth) check whether platform support BLE
        //     Do the check here or in GattServer?
        BluetoothAdapter adapter = BluetoothAdapter.getDefaultAdapter();
        IBluetoothManager managerService = adapter.getBluetoothManager();
        try {
            IBluetoothGatt iGatt = managerService.getBluetoothGatt();
            if (iGatt == null) {
                // BLE …
