获取蓝牙键值并传递给内核的流程如下:
1. 在Android TV原生代码中,创建一个BroadcastReceiver来监听蓝牙键值的变化。
```
private final BroadcastReceiver mBluetoothReceiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {
String action = intent.getAction();
if (BluetoothHidDevice.ACTION_REPORT == action) {
byte[] report = intent.getByteArrayExtra(BluetoothHidDevice.EXTRA_REPORT);
// 将report传递给内核
// ...
}
}
};
```
2. 注册BroadcastReceiver,监听BluetoothHidDevice.ACTION_REPORT广播
```
IntentFilter filter = new IntentFilter();
filter.addAction(BluetoothHidDevice.ACTION_REPORT);
registerReceiver(mBluetoothReceiver, filter);
```
3. 将接收到的蓝牙键值通过JNI调用传递给内核。
```
JNIEXPORT void JNICALL
Java_com_android_tv_util_NativeUtils_sendKey(JNIEnv *env, jobject instance, jint keyCode) {
// 将keyCode传递给内核
// ...
}
```
4. 在Android TV应用中调用JNI方法,将接收到的蓝牙键值传递给内核。
```
NativeUtils.sendKey(keyCode);
```
