How do I calculate the distance covered by the user using the google fit API? Currently I am using google Fit History Api like this :
DataReadRequest readRequest = new DataReadRequest.Builder()
.aggregate(DataType.TYPE_DISTANCE_DELTA, DataType.AGGREGATE_DISTANCE_DELTA)
.bucketByTime(1, TimeUnit.DAYS)
.setTimeRange(startTime, endTime, TimeUnit.MILLISECONDS)
.build();
DataReadResult dataReadResult =
Fitness.HistoryApi.readData(mGoogleApiClient, readRequest).await(1, TimeUnit.MINUTES);
But this is not returning any value Does anyone a clue?
You need to add one more scope when you instantiate GoogleApiClient.Builder:
".addScope(new Scope(Scopes.FITNESS_LOCATION_READ))"
And you also need to gain Location permission by adding this permission in manifest file:
<manifet>
...
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<aplication/>
</manifest>
and in your activity, add this method:
public void request_location_permission() {
// If location permission was not granted yet, request it. Otherwise, request nothing and
// just do what you want.
if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) !=
PackageManager.PERMISSION_GRANTED) {
PermissionUtils.requestPermission(this, LOCATION_PERMISSION_REQUEST_CODE,
Manifest.permission.ACCESS_FINE_LOCATION, false);
} else {
process();
}
}
PermissionUtils is my own class, you can use it to have a prompt look if you want to see a result first:
public abstract class PermissionUtils {
/**
* Requests the fine location permission. If a rationale with an additional explanation should
* be shown to the user, displays a dialog that triggers the request.
*/
public static void requestPermission(AppCompatActivity activity, int requestId,
String permission, boolean finishActivity) {
if (ActivityCompat.shouldShowRequestPermissionRationale(activity, permission)) {
// Display a dialog with rationale, this dialog wil request permission by itself.
PermissionUtils.RationaleDialog.newInstance(requestId, finishActivity)
.show(activity.getSupportFragmentManager(), "dialog");
} else {
// Location permission has not been granted yet, request it.
ActivityCompat.requestPermissions(activity, new String[]{permission}, requestId);
}
}
/**
* Checks if the result contains a {@link PackageManager#PERMISSION_GRANTED} result for a
* permission from a runtime permissions request.
*
* @see android.support.v4.app.ActivityCompat.OnRequestPermissionsResultCallback
*/
public static boolean isPermissionGranted(String[] grantPermissions, int[] grantResults,
String permission) {
for (int i = 0; i < grantPermissions.length; i++) {
if (permission.equals(grantPermissions[i])) {
return grantResults[i] == PackageManager.PERMISSION_GRANTED;
}
}
return false;
}
/**
* A dialog that displays a permission denied message.
*/
public static class PermissionDeniedDialog extends DialogFragment {
private static final String ARGUMENT_FINISH_ACTIVITY = "finish";
private boolean mFinishActivity = false;
/**
* Creates a new instance of this dialog and optionally finishes the calling Activity
* when the 'Ok' button is clicked.
*/
public static PermissionDeniedDialog newInstance(boolean finishActivity) {
Bundle arguments = new Bundle();
arguments.putBoolean(ARGUMENT_FINISH_ACTIVITY, finishActivity);
PermissionDeniedDialog dialog = new PermissionDeniedDialog();
dialog.setArguments(arguments);
return dialog;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
mFinishActivity = getArguments().getBoolean(ARGUMENT_FINISH_ACTIVITY);
return new AlertDialog.Builder(getActivity())
.setMessage(R.string.location_permission_denied)
.setPositiveButton(android.R.string.ok, null)
.create();
}
@Override
public void onDismiss(DialogInterface dialog) {
super.onDismiss(dialog);
if (mFinishActivity) {
Toast.makeText(getActivity(), R.string.permission_required_toast,
Toast.LENGTH_SHORT).show();
getActivity().finish();
}
}
}
/**

* permission.
* <p>
* The activity should implement
* {@link android.support.v4.app.ActivityCompat.OnRequestPermissionsResultCallback}

*/
public static class RationaleDialog extends DialogFragment {
private static final String ARGUMENT_PERMISSION_REQUEST_CODE = "requestCode";
private static final String ARGUMENT_FINISH_ACTIVITY = "finish";
private boolean mFinishActivity = false;
/**

*/
public static RationaleDialog newInstance(int requestCode, boolean finishActivity) {
Bundle arguments = new Bundle();
arguments.putInt(ARGUMENT_PERMISSION_REQUEST_CODE, requestCode);
arguments.putBoolean(ARGUMENT_FINISH_ACTIVITY, finishActivity);
RationaleDialog dialog = new RationaleDialog();
dialog.setArguments(arguments);
return dialog;
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Bundle arguments = getArguments();
final int requestCode = arguments.getInt(ARGUMENT_PERMISSION_REQUEST_CODE);
mFinishActivity = arguments.getBoolean(ARGUMENT_FINISH_ACTIVITY);
return new AlertDialog.Builder(getActivity())
.setMessage(R.string.permission_rationale_location)
.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// After click on Ok, request the permission.
ActivityCompat.requestPermissions(getActivity(),
new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
requestCode);
// Do not finish the Activity while requesting permission.
mFinishActivity = false;
}
})
.setNegativeButton(android.R.string.cancel, null)
.create();
}
@Override
public void onDismiss(DialogInterface dialog) {
super.onDismiss(dialog);
if (mFinishActivity) {
Toast.makeText(getActivity(),
R.string.permission_required_toast,
Toast.LENGTH_SHORT)
.show();
getActivity().finish();
}
}
}
This is my way to get granted Location permission from user by creating my own Rational dialog, you can do in a different way by searching how to get location permission on google.
Hope this will help,
Mttdat.
