使用 google fit 时 GoogleApiClient 未连接

Question

我正在尝试使用 google 拟合获取步行步数的数据。我正在实现此 tutorial 中的代码。我被要求提供我想要连接的帐户 google 适合。我 select 帐户后，它连接不上。在我 select 帐户之后， onActivityResult 被调用但是 mApiClient.isConnecting() && mApiClient.isConnected() 都是 false 和 resultCode == RESULT_CANCELED 。因此，不会调用下一个请求访问拟合数据权限的警告对话框。我无法理解为什么 mApiClient 没有连接。我已按照有关创建 oauth2、启用 Fitness Api 并提供 keyStore.

的教程中所示的步骤进行操作

public class MainActivity extends AppCompatActivity implements OnDataPointListener,
    GoogleApiClient.ConnectionCallbacks,
    GoogleApiClient.OnConnectionFailedListener {

private static final int REQUEST_OAUTH = 1;
private static final String AUTH_PENDING = "auth_state_pending";
private boolean authInProgress = false;
private GoogleApiClient mApiClient;

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

    if (savedInstanceState != null) {
        authInProgress = savedInstanceState.getBoolean(AUTH_PENDING);
    }

    mApiClient = new GoogleApiClient.Builder(this)
            .addApi(Fitness.SENSORS_API)
            .addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ_WRITE))
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .build();
}

@Override
protected void onStart() {
    super.onStart();
    mApiClient.connect();
}

@Override
protected void onStop() {
    super.onStop();

    Fitness.SensorsApi.remove( mApiClient, this )
            .setResultCallback(new ResultCallback<Status>() {
                @Override
                public void onResult(Status status) {
                    if (status.isSuccess()) {
                        mApiClient.disconnect();
                    }
                }
            });
}

private void registerFitnessDataListener(DataSource dataSource, DataType dataType) {

    SensorRequest request = new SensorRequest.Builder()
            .setDataSource( dataSource )
            .setDataType( dataType )
            .setSamplingRate( 3, TimeUnit.SECONDS )
            .build();

    Fitness.SensorsApi.add(mApiClient, request, this)
            .setResultCallback(new ResultCallback<Status>() {
                @Override

                        Log.e("GoogleFit", "SensorApi successfully added");
                    } else {
                        Log.e("GoogleFit", "adding status: " + status.getStatusMessage());
                    }
                }
            });
}

                }
            }
        }
    };

    Fitness.SensorsApi.findDataSources(mApiClient, dataSourceRequest)
            .setResultCallback(dataSourcesResultCallback);

Answer 1

回答帮助我弄清楚了它是如何解决的。将这些依赖项添加到 gradle 文件中。 Google 已更新 ApiClient 库，它们需要 google 登录身份验证才能访问 API

compile 'com.google.android.gms:play-services-fitness:9.0.1'
compile 'com.google.android.gms:play-services-auth:9.0.1'

我添加了整个代码，因为不同的错误可能会给出 RESULT_CANCELED 作为输出。

public class MainActivity extends Activity implements GoogleApiClient.OnConnectionFailedListener,
GoogleApiClient.ConnectionCallbacks, OnDataPointListener {
private static final String TAG = "CCC";
private static final String AUTH_PENDING = "isAuthPending";
GoogleApiClient googleApiClient;
private boolean authInProgress = false;

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

    //authInProgress code is useful because the onStop may be called while authentication is not complete.
    //In such case this tells it to complete it
    if (savedInstanceState != null) {
        authInProgress = savedInstanceState.getBoolean(AUTH_PENDING);
    }
}

@Override
protected void onStart() {
    super.onStart();
    //very important that the following lines are called in onStart
    //when they are called in onCreate, when the permission fragment opens up, onStop gets called which disconnects the api client.
    //after which it needs to be reConnected which does not happen as the apiClient is built in onCreate
    //Hence these should be called in onStart or probably onResume.
    googleApiClient = googleFitBuild(this, this, this);
    googleFitConnect(this, googleApiClient);
}

public static GoogleApiClient googleFitBuild(Activity activity, GoogleApiClient.ConnectionCallbacks connectionCallbacks, GoogleApiClient.OnConnectionFailedListener failedListener){
    GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
            .requestEmail()
            .requestScopes(new Scope(Scopes.FITNESS_ACTIVITY_READ_WRITE))
            .build();

    return new GoogleApiClient.Builder(activity)
//without GOOGLE_SIGN_IN_API, RESULT_CANCELED is always the output
//The new version of google Fit requires that the user authenticates with gmail account
            .addApi(Auth.GOOGLE_SIGN_IN_API, gso)
            .addConnectionCallbacks(connectionCallbacks)
            .addOnConnectionFailedListener(failedListener)
            .addApi(Fitness.HISTORY_API)
