【问题描述】：
我正在尝试使用 google fit 获取有关步行步数的数据。我正在实现来自这个tutorial 的代码。我被要求提供我想连接 google fit 的帐户。在我选择帐户后，它没有连接。选择帐户后，将调用 onActivityResult 但 mApiClient.isConnecting() && mApiClient.isConnected() 既是 false 又是 resultCode == RESULT_CANCELED 。因此，不会调用用于请求访问拟合数据的权限的下一个警报对话框。我不明白为什么 mApiClient 没有连接。我已按照教程中有关创建 oauth2、启用 Fitness Api 和提供 keyStore 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
public void onResult(Status status) {
if (status.isSuccess()) {
Log.e("GoogleFit", "SensorApi successfully added");
} else {
Log.e("GoogleFit", "adding status: " + status.getStatusMessage());
}
}
});
}
@Override
public void onConnected(Bundle bundle) {
DataSourcesRequest dataSourceRequest = new DataSourcesRequest.Builder()
.setDataTypes( DataType.TYPE_STEP_COUNT_CUMULATIVE )
.setDataSourceTypes( DataSource.TYPE_RAW )
.build();
ResultCallback<DataSourcesResult> dataSourcesResultCallback = new ResultCallback<DataSourcesResult>() {
@Override
public void onResult(DataSourcesResult dataSourcesResult) {
for( DataSource dataSource : dataSourcesResult.getDataSources() ) {
if( DataType.TYPE_STEP_COUNT_CUMULATIVE.equals( dataSource.getDataType() ) ) {
registerFitnessDataListener(dataSource, DataType.TYPE_STEP_COUNT_CUMULATIVE);
}
}
}
};
Fitness.SensorsApi.findDataSources(mApiClient, dataSourceRequest)
.setResultCallback(dataSourcesResultCallback);
}
@Override
public void onConnectionFailed(ConnectionResult connectionResult) {
if( !authInProgress ) {
try {
authInProgress = true;
connectionResult.startResolutionForResult( MainActivity.this, REQUEST_OAUTH );
} catch(IntentSender.SendIntentException e ) {
Log.e( "GoogleFit", "sendingIntentException " + e.getMessage() );
}
} else {
Log.e( "GoogleFit", "authInProgress" );
}
}
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if( requestCode == REQUEST_OAUTH ) {
authInProgress = false;
if( resultCode == RESULT_OK ) {
if( !mApiClient.isConnecting() && !mApiClient.isConnected() ) {
mApiClient.connect();
}
} else if( resultCode == RESULT_CANCELED ) {
Log.e( "GoogleFit", "RESULT_CANCELED" );
}
} else {
Log.e("GoogleFit", "requestCode NOT request_oauth");
}
}
@Override
public void onConnectionSuspended(int i) {
}
@Override
public void onDataPoint(DataPoint dataPoint) {
for( final Field field : dataPoint.getDataType().getFields() ) {
final Value value = dataPoint.getValue( field );
runOnUiThread(new Runnable() {
@Override
public void run() {
Toast.makeText(getApplicationContext(), "Field: " + field.getName() + " Value: " + value, Toast.LENGTH_SHORT).show();
}
});
}
}
}
