[英]Step Counter Google FIT API
我目前正在尝试使用 Google Fit API。这是我使用 API 的第一个应用程序,我主要是通过遵循 Google 的文档。
下面是我的代码,它似乎有问题
我的问题是它似乎没有更新计步器。
public class MainActivity extends Activity
implements GoogleApiClient.ConnectionCallbacks, GoogleApiClient.OnConnectionFailedListener {
private static final String TAG = "FitActivity";
//[START Auth_Variable_References]
private static final int REQUEST_OAUTH = 1;
// [END auth_variable_references]
private GoogleApiClient mClient = null;
int mInitialNumberOfSteps = 0;
private TextView mStepsTextView;
private boolean mFirstCount = true;
// Create Builder View
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mStepsTextView = (TextView) findViewById(R.id.textview_number_of_steps);
}
private void connectFitness() {
Log.i(TAG, "Connecting...");
// Create the Google API Client
mClient = new GoogleApiClient.Builder(this)
// select the Fitness API
.addApi(Fitness.API)
// specify the scopes of access
.addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ))
.addScope(new Scope(Scopes.FITNESS_LOCATION_READ))
.addScope(new Scope(Scopes.FITNESS_BODY_READ_WRITE))
// provide callbacks
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
// Connect the Google API client
mClient.connect();
}
// Manage OAuth authentication
@Override
public void onConnectionFailed(ConnectionResult result) {
// Error while connecting. Try to resolve using the pending intent returned.
if (result.getErrorCode() == ConnectionResult.SIGN_IN_REQUIRED ||
result.getErrorCode() == FitnessStatusCodes.NEEDS_OAUTH_PERMISSIONS) {
try {
// Request authentication
result.startResolutionForResult(this, REQUEST_OAUTH);
} catch (IntentSender.SendIntentException e) {
Log.e(TAG, "Exception connecting to the fitness service", e);
}
} else {
Log.e(TAG, "Unknown connection issue. Code = " + result.getErrorCode());
}
}
@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == REQUEST_OAUTH) {
if (resultCode == RESULT_OK) {
// If the user authenticated, try to connect again
mClient.connect();
}
}
}
@Override
public void onConnectionSuspended(int i) {
// If your connection gets lost at some point,
// you'll be able to determine the reason and react to it here.
if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_NETWORK_LOST) {
Log.i(TAG, "Connection lost. Cause: Network Lost.");
} else if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_SERVICE_DISCONNECTED) {
Log.i(TAG, "Connection lost. Reason: Service Disconnected");
}
}
@Override

Log.i(TAG, "Connected!");
// Now you can make calls to the Fitness APIs.
invokeFitnessAPIs();
}
private void invokeFitnessAPIs() {
// Create a listener object to be called when new data is available
OnDataPointListener listener = new OnDataPointListener() {
@Override
public void onDataPoint(DataPoint dataPoint) {
for (Field field : dataPoint.getDataType().getFields()) {
Value val = dataPoint.getValue(field);
updateTextViewWithStepCounter(val.asInt());
}
}
};
//Specify what data sources to return
DataSourcesRequest req = new DataSourcesRequest.Builder()
.setDataSourceTypes(DataSource.TYPE_DERIVED)
.setDataTypes(DataType.TYPE_STEP_COUNT_DELTA)
.build();
// Invoke the Sensors API with:
// - The Google API client object
// - The data sources request object

// 4. Check the result asynchronously
regResult.setResultCallback(new ResultCallback<Status>()

if (status.isSuccess()) {
Log.d(TAG, "listener registered");
// listener registered
} else {
Log.d(TAG, "listener not registered");
// listener not registered
}
}
});
}
// Update the Text Viewer with Counter of Steps..
private void updateTextViewWithStepCounter(final int numberOfSteps) {
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getBaseContext(), "On Datapoint!", Toast.LENGTH_SHORT);
if(mFirstCount && (numberOfSteps != 0)) {
mInitialNumberOfSteps = numberOfSteps;
mFirstCount = false;
}
if(mStepsTextView != null){
mStepsTextView.setText(String.valueOf(numberOfSteps - mInitialNumberOfSteps));
}
}
});
}
//Start
@Override
protected void onStart() {
super.onStart();
mFirstCount = true;
mInitialNumberOfSteps = 0;
if (mClient == null || !mClient.isConnected()) {
connectFitness();
}
}
//Stop
@Override

super.onStop();

}
}
首先,按照以下步骤在 Google API Console 中启用 Fitness API 并获取 OAuth 2.0 客户端 ID。
1.转到Google API 控制台。
2.选择一个项目,或创建一个新项目。 对您的应用程序的 Android 和 REST 版本使用相同的项目。
3.单击继续以启用 Fitness API。
4.单击转到凭据。
5.单击新凭据,然后选择 OAuth 客户端 ID。
6.在应用程序类型下选择 Android。
7.在出现的对话框中,输入您的应用程序的 SHA-1 指纹和包名称。 例如:
BB:0D:AC:74:D3:21:E1:43:67:71:9B:62:91:AF:A1:66:6E:44:5D:75
com.example.android.fit-example
8.单击创建。 您的新 Android OAuth 2.0 客户端 ID 和密钥显示在您项目的 ID 列表中。 OAuth 2.0 客户端 ID 是一串字符,如下所示:

注意:: :: 有时在某些设备中它不会检测 Step 值,因此每当您开发和使用此代码时,请始终卸载应用程序,然后重新安装应用程序。 那么这工作正常。
**Don't forget to add this permission**
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
您可以尝试StepSensor从OrangeGangster的图书馆。
它包含一个自定义Service
允许从 Android 4.4 引入的Sensor.TYPE_STEP_COUNTER
收集数据(仅适用于支持此硬件功能的设备)。
这段代码对我有用!
构建客户端:
mClient = new GoogleApiClient.Builder(this)
.addApi(Fitness.SENSORS_API)
.addScope(new Scope(Scopes.FITNESS_BODY_READ_WRITE))
.addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ_WRITE))
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
调用传感器 API :
private void invokeSensorsAPI() {
Fitness.SensorsApi.add(
mClient,
new SensorRequest.Builder()
.setDataType(DataType.TYPE_STEP_COUNT_DELTA)
.setSamplingRate(1, TimeUnit.SECONDS)
.build(),
this)
.setResultCallback(new ResultCallback<Status>() {
@Override
public void onResult(Status status) {
if (status.isSuccess()) {
Log.i(TAG, "Sensor Listener registered!");
} else {
Log.i(TAG, "Sensor Listener not registered.");
}
}
});
}
接收数据:
@Override
public void onDataPoint(DataPoint dataPoint) {
for (Field field : dataPoint.getDataType().getFields()) {
Value val = dataPoint.getValue(field);
Log.i(TAG, "Detected DataPoint field: " + field.getName());
Log.i(TAG, "Detected DataPoint value: " + val);
final int value = val.asInt();
if (field.getName().compareToIgnoreCase("steps") == 0) {
runOnUiThread(new Runnable() {
@Override
public void run() {
tv.setText("Value" + value)
}
});
}
}
}
我希望它有帮助
我认为你在这里犯了一个错误
if (resultCode == RESULT_OK) {
// If the user authenticated, try to connect again
mClient.connect()
}
相反,它应该是
if (resultCode != RESULT_OK) {
// If the user is not authenticated, try to connect again/ resultcode = RESULT_CANCEL
mClient.connect()
} else {
onConnected(null);
}
通过您的代码 invokeFitnessApis 永远不会被调用,因为您在成功连接后重新连接 googleapiclient。
