android Googlefit接入指南

官方文档使劲戳这里
如果无法加载，少年你需要翻墙再点。

因为app里面接入了googlefit。并且一直有客户投诉说googlefit上传数据不准确。查看googlefit开发官网才发现，googfit api都已经更新了。并且接入过程中也遇到一些坑。在此记录以防后面再入坑

build.gradle添加依赖

dependencies {
    ...
  compile 'com.google.android.gms:play-services-fitness:16.0.1'
  compile 'com.google.android.gms:play-services-auth:16.0.1'
    ...
}

构建FitnessOptions，DataType表示你要写入到googlfit的数据类型，数据类型有很多，根据需要添加

FitnessOptions fitnessOptions = FitnessOptions.builder()
                //步数
                .addDataType(DataType.TYPE_STEP_COUNT_DELTA, FitnessOptions.ACCESS_WRITE)
                //距离
                .addDataType(DataType.TYPE_DISTANCE_DELTA, FitnessOptions.ACCESS_WRITE)
                .build();

//下面登录google账号。并且授权上面添加的那些数据授权的弹框

public void connectGoogle() {
        try {
            //如果已经登录过google账号。则可以拿到账号
            account=GoogleSignIn.getLastSignedInAccount(activity);
            if (account==null) {
                //没有。则要登录
                signIn();
            }else{
                //有，则要订阅
                sunbscrerib();
            }
        }catch (Exception e){
            e.printStackTrace();
           
        }
    }

//此方法会弹框google账号登录的弹框

private void signIn(){
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN).requestEmail().build();
    GoogleSignInClient mGoogleSignInClient = GoogleSignIn.getClient(activity, gso);
    Intent signInIntent = mGoogleSignInClient.getSignInIntent();
    activity.startActivityForResult(signInIntent, GOOGLE_SIGN_IN);
}

/**
 * 在activity的onActivityResult方法里面调用，回调是否登录账号成功。
 * @param data
 */
public void handleSignInResult(int requestCode,Intent data) {
    if (requestCode!=GOOGLE_SIGN_IN){
        return;
    }
    try {
        GoogleSignInResult result=getSignInResultFromIntent(data);
        if (result.isSuccess()) {
            account = getSignedInAccountFromIntent(data).getResult(ApiException.class);
            sunbscrerib();
        }
    } catch (ApiException e) {
        dAndSave("signInResult:failed code=" + e.getStatusCode());
    }
}

private void sunbscrerib(){
            account=GoogleSignIn.getLastSignedInAccount(activity);
            if (account==null){
                return;
            }
        //判断是否有写入数据的权限，这个会弹出授权写入数据的弹框
        if (!GoogleSignIn.hasPermissions(account, fitnessOptions)) {
            GoogleSignIn.requestPermissions(
                    activity, // your activity
                    GOOGLE_FIT_PERMISSIONS_REQUEST_CODE,
                    account,
                    fitnessOptions);
        }else{
              subscriptionData();
        }
    }

如果已经有权限了，则订阅，订阅成功后就可以上传数据了

 private void subscriptionData() {
    subscribe(DataType.TYPE_STEP_COUNT_DELTA);// 订阅步数
    subscribe(DataType.TYPE_DISTANCE_DELTA);// 距离
}

// 订阅
    private void subscribe(final DataType dataType) {
            GoogleSignInAccount account = GoogleSignIn.getLastSignedInAccount(activity);
            if (account == null) {
                return;
            }
        Fitness.getRecordingClient(activity, GoogleSignIn.getLastSignedInAccount(activity))
                .subscribe(dataType)
                .addOnSuccessListener(new OnSuccessListener<Void>() {
                    @Override
                    public void onSuccess(Void aVoid) {
                        //每订阅成功一个，会回调这个方法
                    }
                })
                .addOnFailureListener(new OnFailureListener() {
                    @Override
                    public void onFailure(@NonNull Exception e) {
                    
                    }
                });
    }




DataSet stepDataSet;
DataSet distanceDataSet;
//创建要上传的步数数据对象
stepDataSet = createDataForRequest(DataType.TYPE_STEP_COUNT_DELTA,Field.FIELD_STEPS, stepAllCount, lastUploadTime, currentUploadTime);// 步数
//创建要上传的距离数据对象
distanceDataSet = createDataForRequest(DataType.TYPE_DISTANCE_DELTA,Field.FIELD_DISTANCE ,allDistance, lastUploadTime, currentUploadTime);// 距离


 /**

 */
private DataSet createDataForRequest(DataType dataType,Field field, Object values, long startTime, long endTime) {
    DataSource dataSource =
            new DataSource.Builder()
                    .setAppPackageName(activity)
                    .setDataType(dataType)
                    .setStreamName("streamName")
                    .setType(DataSource.TYPE_RAW)
                    .build();
    DataSet dataSet = DataSet.create(dataSource);
    DataPoint dataPoint =
            dataSet.createDataPoint().setTimeInterval(startTime, endTime, TimeUnit.MILLISECONDS);
    if (dataType == DataType.TYPE_CALORIES_EXPENDED||dataType==DataType.TYPE_HEART_RATE_BPM) {
        dataPoint.getValue(field).setFloat((Float) values);
    } else {
        //如果是float类型则要调用setFloagValues  
        if (values instanceof Integer) {
            dataPoint.setIntValues((Integer) values);
        } else {

            dataPoint = dataPoint.setFloatValues((Float) values);
        }
    }
    dataSet.add(dataPoint);
    return dataSet;
}

数据已经准备好了。现在上传到googlefit。因为是网络操作，因此在后台线程调用

new AsyncTaskUtil(new AsyncTaskUtil.IAsyncTaskCallBack() {
        @Override
        public Object doInBackground(String... arg0) {
            Task<Void> responseStep = Fitness.getHistoryClient(activity, GoogleSignIn.getLastSignedInAccount(activity)).insertData(stepDataSet);
            Task<Void> responseDistance = Fitness.getHistoryClient(activity, GoogleSignIn.getLastSignedInAccount(activity)).insertData(distanceDataSet);
          

            //等待任务完成
            while(!responseStep.isComplete()||!responseDistance.isComplete()) {
                try {
                    Thread.sleep(1000);
                } catch (InterruptedException e) {
                    e.printStackTrace();
                }
            }
           
            return null;
        }

        @Override
        public void onPostExecute(Object result) {
            //数据上传完成
        }
    }).execute("");

如果数据上传成功。打开googlefit app就会看到googlefit 里面的数据已经更新了。
