android应用程序与可穿戴伴侣应用程序之间的同步振动

问题描述

我正在开发一个需要实现可穿戴应用程序的android应用程序。我需要设备以同步方式振动，但出现问题。首次启动时，智能手表会延迟近半秒钟开始振动。一旦停止并重新启动振动，如果在短时间内完成振动，则振动是同步的，如果等待4-5秒，则问题会再次发生。 这是我的代码：

MainActivity Wear

package com.example.progettogio;

import android.os.Bundle;
import android.os.PowerManager;
import android.support.wearable.activity.WearableActivity;
import android.util.Log;
import android.widget.TextView;

import com.example.progettogio.vibration.soundVibrationThread;
import com.google.android.gms.tasks.OnCompleteListener;
import com.google.android.gms.tasks.Task;
import com.google.android.gms.wearable.CapabilityClient;
import com.google.android.gms.wearable.CapabilityInfo;
import com.google.android.gms.wearable.Node;
import com.google.android.gms.wearable.Wearable;

import java.util.Set;

public class MainActivity extends WearableActivity {

    private TextView mTextView;
    private Set<Node> nodes;
    private String text = "Paired with:\n";
    private SoundVibrationThread mSoundVibrationThread;
    private PowerManager.WakeLock mWakeLock;
    private PowerManager mPowerManager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mPowerManager = (PowerManager) getSystemService(POWER_SERVICE);
        mWakeLock = mPowerManager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK,"SignalsServer::SensorsWakeLock");
        mWakeLock.acquire();
        mTextView = (TextView) findViewById(R.id.text);
        //Wear
        Task<CapabilityInfo> capabilityInfoTask = Wearable.getCapabilityClient(getApplicationContext())
                .getCapability("watch_server",CapabilityClient.FILTER_REACHABLE);

        capabilityInfoTask.addOnCompleteListener(new OnCompleteListener<CapabilityInfo>() {
            @Override
            public void onComplete(Task<CapabilityInfo> task) {
                if (task.isSuccessful()) {
                    CapabilityInfo capabilityInfo = task.getResult();
                    nodes = capabilityInfo.getNodes();
                    for (Node node : nodes)
                        text += node.getdisplayName() + "\n";
                    mTextView.setText(text);
                } else {
                    Log.d("MainActivityWear","Capability request Failed to return any results.");
                }

            }
        });

        Wearable.getMessageClient(getApplicationContext()).addListener((messageEvent) -> {
            vibrate(new String(messageEvent.getData()));
        });

        // Enables Always-on
        setAmbientEnabled();
    }


    public void vibrate(String message) {
        if (!message.equals("STOP")) {
            if (mWakeLock != null)
                mWakeLock.acquire(5 * 60 * 1000);
            int bpm = Integer.parseInt(message);
            mSoundVibrationThread = new SoundVibrationThread(getApplicationContext(),bpm);
            mSoundVibrationThread.start();
        } else if (mSoundVibrationThread != null) {
            mSoundVibrationThread.end();
            if (mWakeLock != null)
                if (mWakeLock.isHeld())
                    mWakeLock.release();
        }
    }
}

Gradle文件磨损

负责在智能手机应用上启动振动的按钮的OnClickListener

 soundVibrationButton.setonClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                if(soundVibrationOn){
                    mSoundVibrationThread.end();
                    soundVibrationOn=false;
                    if(smartWatchConnected){
                        for (Node node : nodes)
                            Wearable.getMessageClient(getApplicationContext()).sendMessage(
                                    node.getId(),"/stop","STOP".getBytes());
                    }
                }
                else {
                    if(smartWatchConnected){
                        if (nodes != null) {
                            for (Node node : nodes)
                                Wearable.getMessageClient(getApplicationContext()).sendMessage(
                                        node.getId(),"/vibration","30".getBytes());
                        }
                    }
                    mSoundVibrationThread = new SoundVibrationThread(getApplicationContext(),true,30);
                    mSoundVibrationThread.start();

                    soundVibrationOn=true;
                }
