Java 如何使用google Oauth？我正在使用Android接收连接失败错误

我已经获得了一个android api密钥，并将其放在我的清单文件中。我还使用谷歌开发者控制台获得了我的clientID和SHA1指纹。我不确定是否需要在我的项目中包含我的客户ID

我的客户类：

public class Client {
    private static final int REQUEST_OAUTH = 1;

    private GoogleApiClient client;
    private boolean authInProgress = false;

    private Display display;

    public interface Connection {
        public void onConnected();
    }
    private Connection connection;

    public Client(final Activity activity, final Connection connection, final Display display) {
        this.display = display;
        this.connection = connection;
        client = new GoogleApiClient.Builder(activity)
                .addApi(Fitness.SENSORS_API)
                .addApi(Fitness.HISTORY_API)
                .addApi(Fitness.RECORDING_API)
                .addApi(Fitness.CONFIG_API)
                .addScope(SCOPE_LOCATION_READ)
                .addScope(SCOPE_ACTIVITY_READ)
                .addScope(SCOPE_BODY_READ_WRITE)
                .addConnectionCallbacks(
                        new GoogleApiClient.ConnectionCallbacks() {

                            @Override
                            public void onConnected(Bundle bundle) {
                                display.show("Connected");
                                connection.onConnected();
                            }

                            @Override
                            public void onConnectionSuspended(int i) {
                                display.show("Connection suspended");
                                if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_NETWORK_LOST) {
                                    display.show("Connection lost. Cause: Network Lost.");
                                } else if (i == GoogleApiClient.ConnectionCallbacks.CAUSE_SERVICE_DISCONNECTED) {
                                    display.show("Connection lost. Reason: Service Disconnected");
                                }
                            }
                        }
                )
                .addOnConnectionFailedListener(
                        new GoogleApiClient.OnConnectionFailedListener() {
                            // Called whenever the API client fails to connect.
                            @Override
                            public void onConnectionFailed(ConnectionResult result) {
                                display.log("Connection failed. Cause: " + result.toString());
                                if (!result.hasResolution()) {
                                    GooglePlayServicesUtil.getErrorDialog(result.getErrorCode(), activity, 0).show();
                                    return;
                                }

                                if (!authInProgress) {
                                    try {
                                        display.show("Attempting to resolve failed connection");
                                        authInProgress = true;

                                    } catch (IntentSender.SendIntentException e) {

                                }
                            }
                        }
                )
                .build();
    }

    public void connect() {
        client.connect();
    }

    public void disconnect() {
        if (client.isConnected()) {
            client.disconnect();
        }
    }

    //        disable should be called only for revoking authorization in GoogleFit
    public void revokeAuth() {
        PendingResult<Status> pendingResult = ConfigApi.disableFit(client);
    }

    public GoogleApiClient getClient() {
        return client;
    }

您需要创建一个outh2客户端id，并从api面板启用fitness api。你不会在那里找到它，你必须在搜索栏的上方键入它。然后它将用于参考
