我正在尝试为我的论文项目构建一个bpm计数器。我是一个关于googlefitness api的新手，所以我首先从git克隆google的step计数器示例(如果感兴趣，请链接[here][1]）。我设置了一切，我授权了我的帐户，将其连接到一个云项目，使用keytool获得sha-1证书，但我仍然无法得到我所要求的数据的响应，无论是bpm还是steps。我在xml文件中根据需要设置每个权限，但仍然面临这个问题。下面，我给你一些我的代码的一部分，如果你需要任何其他lmk。提前感谢您的回复。
xml清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.myapplication">
    <uses-permission android:name="android.permission.ACTIVITY_RECOGNITION" />
    <uses-permission android:name="com.google.android.gms.permission.ACTIVITY_RECOGNITION" />

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

登录功能：

private fun fitSignIn(requestCode: FitActionRequestCode) {
            if (oAuthPermissionsApproved()) {
                performActionForRequestCode(requestCode)
            } else {
                requestCode.let {
                    GoogleSignIn.requestPermissions(
                            this,
                            requestCode.ordinal,
                            getGoogleAccount(), fitnessOptions)
                }
            }
        }

        override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent?) {
            super.onActivityResult(requestCode, resultCode, data)

            when (resultCode) {
                RESULT_OK -> {
                    val postSignInAction = FitActionRequestCode.values()[requestCode]
                    postSignInAction.let {
                        performActionForRequestCode(postSignInAction)
                    }
                }
                else -> oAuthErrorMsg(requestCode, resultCode)
            }
        }

选择我的帐户时的代码请求：

private fun performActionForRequestCode(requestCode: FitActionRequestCode) = when (requestCode) {
        FitActionRequestCode.READ_DATA -> readData()
        FitActionRequestCode.SUBSCRIBE -> subscribe()
    }

    private fun oAuthErrorMsg(requestCode: Int, resultCode: Int) {
        val message = """
            There was an error signing into Fit. Check the troubleshooting section of the README
            for potential issues.
            Request code was: $requestCode
            Result code was: $resultCode
        """.trimIndent()
        Log.e(TAG, message)
    }

    private fun oAuthPermissionsApproved() = GoogleSignIn.hasPermissions(getGoogleAccount(), fitnessOptions)
private fun getGoogleAccount() = GoogleSignIn.getAccountForExtension(this, fitnessOptions)

在请求数据时，我总是以结果0结束。

我已经三次检查了googlefit的faq中的所有操作是否正确，并且我已经为我的项目启用了fitness api，但是我仍然没有得到任何结果。如果有人能给我指出正确的方向，我将不胜感激。提前感谢[1]：https://github.com/android/fit-samples/tree/master/stepcounterkotlin [2]: https://i.stack.imgur.com/zvtni.png [3]: https://i.stack.imgur.com/ubtpb.png
