使用Google Fit时GoogleApiClient无法连接 [英] GoogleApiClient not connecting while using google fit

问题描述

我正在尝试获取有关使用Google Fit行走的步数的数据.我正在从教程实现代码一个>.我被要求提供我要从中连接google fit的帐户.选择帐户后，它没有连接.选择帐户后，将调用onActivityResult，但mApiClient.isConnecting()&& mApiClient.isConnected()都是false和resultCode == RESULT_CANCELED.因此，未调用用于请求访问拟合数据的权限的下一个警报对话框.我无法理解为什么mApiClient无法连接.我已按照教程中显示的有关创建oauth2，启用Fitness Api并提供keyStore的步骤进行操作.

I am trying to get the data for number of steps walked using google fit. I am implementing the code from this tutorial. I am being asked for the account from which I want to connect google fit. After I select the account, it is not connecting. After I select the account, onActivityResult is called but mApiClient.isConnecting() && mApiClient.isConnected() are both false and resultCode == RESULT_CANCELED . Hence, the next alert dialog for requesting permission to access fit data is not being called. I am not able to understand why mApiClient is not connecting. I have followed the steps as shown in the tutorial about creating oauth2, enabling Fitness Api and providing the keyStore.

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";

推荐答案

此答案帮助我弄清楚了有待解决.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apis.

This answer helped me figure out how it was to be solved. Add these dependencies to the gradle file. Google has updated ApiClient Libraries and they require google sign in authentication to access the apis

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

我正在添加整个代码，因为不同的错误可以使RESULT_CANCELED作为输出.

I am adding the entire code as different errors can give RESULT_CANCELED as the output.

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);

    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
