GoogleApi客户端在使用Google fit时无法连接

Question

我正在尝试使用谷歌健身获取步行步数的数据。我正在实现本教程中的代码。我被要求提供我想从中连接谷歌健身的帐户。选择帐户后，它未连接。选择帐户后，调用了onActivityResult，但mApiClient.isConnecting()&&mApiClient.isConnected()既false又resultCode == RESULT_CANCELED。因此，不会调用下一个用于请求访问拟合数据的权限的警报对话框。我无法理解为什么mApiClient没有连接。我已经按照教程中所示的步骤创建了 oauth2、启用健身 API 和提供密钥存储。

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)

Answer 1

这个答案帮助我弄清楚了如何解决。将这些依赖项添加到 gradle 文件中。谷歌已经更新了ApiClient Libraries，他们需要谷歌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'

我正在添加整个代码，因为不同的错误可以提供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.
