WearOS 和 Android 应用程序无法通信

Question

我想在可穿戴设备上显示在 Android 应用程序中输入的数字，但它没有按预期工作。由于 MessageApi 已被弃用，我尝试使用 MessageClient 作为替代品，但它不起作用。我一直在调试，但似乎在发送消息后就停止了，并且没有错误日志来帮助我找出问题。如果有人有开发 Wear OS 设备的经验，可以帮助我吗？

Android：MainActivity

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
    private EditText editText;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        editText = findViewById(R.id.editText);

        Button sendButton = findViewById(R.id.sendButton);
        sendButton.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        if (v.getId() == R.id.sendButton) {
            String text = editText.getText().toString();
            sendMessage(text);
        }
    }

    private void sendMessage(String text) {
        MessageClient messageClient = Wearable.getMessageClient(this);

        
        Task<List<Node>> nodeListTask = Wearable.getNodeClient(this).getConnectedNodes();
        nodeListTask.addOnSuccessListener(nodes -> {
            
            for (Node node : nodes) {
                messageClient.sendMessage(node.getId(), "/data_comm", text.getBytes())
                        .addOnSuccessListener(aVoid -> {
                            
                            Log.d("SendMessage", "Message sent successfully to: " + node.getDisplayName());
                            
                        })
                        .addOnFailureListener(e -> {
                            
                            Log.e("SendMessage", "Failed to send message to: " + node.getDisplayName(), e);
                        });
            }
        }).addOnFailureListener(e -> {
            
            Log.e("SendMessage", "Failed to get connected nodes", e);
        });
    }
}

穿戴操作系统MainActivity

public class MainActivity extends Activity implements MessageClient.OnMessageReceivedListener {
    private TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        textView = findViewById(R.id.textView); 
    }

    @Override
    protected void onResume() {
        super.onResume();
        Wearable.getMessageClient(this).addListener(this);
    }

    @Override
    protected void onPause() {
        super.onPause();
        Wearable.getMessageClient(this).removeListener(this);
    }

    @Override
    public void onMessageReceived(@NonNull final MessageEvent messageEvent) {
        if (messageEvent.getPath().equals("/data_comm")) {
            runOnUiThread(() -> {
                String message = new String(messageEvent.getData());
                textView.setText(message); 
            });
        }
    }

DataListenerService 类

public class DataListenerService extends WearableListenerService {
    private Handler handler = new Handler(Looper.getMainLooper());

    @Override
    public void onDataChanged(DataEventBuffer dataEvents) {
        for (DataEvent event : dataEvents) {
            if (event.getType() == DataEvent.TYPE_CHANGED) {
                DataItem item = event.getDataItem();

                if (item.getUri().getPath().equals("/data_comm")) {
                    DataMap dataMap = DataMapItem.fromDataItem(item).getDataMap();
                    handler.post(() -> Toast.makeText(getApplicationContext(), dataMap.getString("key_data"),
                            Toast.LENGTH_SHORT).show());
                }
            }
        }
    }

    @Override
    public void onMessageReceived(MessageEvent messageEvent) {
        if (messageEvent.getPath().equals("/data_comm_2")) {
            handler.post(() -> Toast.makeText(getApplicationContext(),
                    new String(messageEvent.getData()),
                    Toast.LENGTH_SHORT).show());
        }
    }

Answer 1

请查看以下安全要求，否则您的应用程序将无法相互通信：

• 包名称必须跨设备匹配。
• 包的签名必须跨设备匹配。

---

看起来您的包名称在项目中不匹配：

• com.websarva.wings.android.practice_wear
• com.websarva.wings.android.wear
