TV蓝牙无法被搜索问题解决记录：REQUEST_DISCOVERABLE ActivityNotFoundException

Android TV开发使用谷歌官方推荐方法开启蓝牙可被搜索：

Intent discoverableIntent =
        new Intent(BluetoothAdapter.ACTION_REQUEST_DISCOVERABLE);
discoverableIntent.putExtra(BluetoothAdapter.EXTRA_DISCOVERABLE_DURATION, 300);
startActivity(discoverableIntent);

在移动端上该代码功能正常，但是在TV上会抛错：

android.content.ActivityNotFoundException: No Activity found to handle Intent { act=android.bluetooth.adapter.action.REQUEST_DISCOVERABLE (has extras) }

经过各种检索发现很多人都反馈此问题，但是却没有给出具体解决方案，后面经过咨询公司内资深同事后发现通过反射即可解决此问题：

 Method setDiscoverableTimeout = BluetoothAdapter.class.getMethod("setDiscoverableTimeout", int.class);
            setDiscoverableTimeout.setAccessible(true);
            Method setScanMode = BluetoothAdapter.class.getMethod("setScanMode", int.class, int.class);
            setScanMode.setAccessible(true);
            setDiscoverableTimeout.invoke(adapter, 0);
            setScanMode.invoke(adapter, BluetoothAdapter.SCAN_MODE_CONNECTABLE_DISCOVERABLE, 0);
