Why [onDataPoint] of google fit not call?

Question

I using this code to test google fit : android-fit . This code is working and not occur any exception , but it can't call into function [onDataPoint] when it register Fitness Data

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

        if (hasRuntimePermissions()) {
            findFitnessDataSourcesWrapper();
        } else {
            requestRuntimePermissions();
        }
    }


    private void findFitnessDataSourcesWrapper() {
        if (hasOAuthPermission()) {
            findFitnessDataSources();
        } else {
            requestOAuthPermission();
        }
    }


    private FitnessOptions getFitnessSignInOptions() {
        return FitnessOptions.builder().addDataType(DataType.TYPE_LOCATION_SAMPLE).build();
    }


    private boolean hasOAuthPermission() {
        FitnessOptions fitnessOptions = getFitnessSignInOptions();
        return GoogleSignIn.hasPermissions(GoogleSignIn.getLastSignedInAccount(this), fitnessOptions);
    }


    private void requestOAuthPermission() {
        FitnessOptions fitnessOptions = getFitnessSignInOptions();
        GoogleSignIn.requestPermissions(
                this,
                REQUEST_OAUTH_REQUEST_CODE,
                GoogleSignIn.getLastSignedInAccount(this),
                fitnessOptions);
    }


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


        findFitnessDataSourcesWrapper();
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (resultCode == Activity.RESULT_OK) {
            if (requestCode == REQUEST_OAUTH_REQUEST_CODE) {
                findFitnessDataSources();
            }
        }

                                //.setDataSourceTypes(DataSource.TYPE_RAW)
                                .build())
                .addOnSuccessListener(

                        for (Field field : dataPoint.getDataType().getFields()) {
                            Value val = dataPoint.getValue(field);

This is Result of Logcat outputed:

Log display message [Listener registered!] but Why [onDataPoint] of google fit not call?

I had try remove .setDataSourceTypes(DataSource.TYPE_RAW) , but it still not go to [onDataPoint]

Answer 1

It will work if you change DataSource.TYPE_RAW to DataSource.TYPE_DERIVED And make sure that you are using the 5.0 and above. If you will use the version 4.4 you have to use DataSource.TYPE_ROW
