Problems using HERE API to get my position (Wifi) [UPDATED]

I installed the HERE test product on my tablet (it's an old Android 5.1 tablet without GPS or Cellular data, just Wifi) and it worked well to (approximately) give my position using Wifi.
So I am attempting to program the same in my app.
Downloaded the HERE API, got a freemium license for my app name, input the lines in my manifest:
<meta-data
android:name="com.here.android.maps.appid"
android:value="itkC4uIay69MTXXXXXXX" />
<meta-data
android:name="com.here.android.maps.apptoken"
android:value="NdT8laoCmRysyh8XXXXXXX" />
Included the HERE-sdk in my build, and my Code compiles just fine.
I have code in my MainActivity.onCreate() [EDIT I have added in code to initialize the map engine as recommended by HERE support below]:
MapEngine.getInstance().init(this, new OnEngineInitListener() {
#Override
public void onEngineInitializationCompleted(Error error) {
if (error == Error.NONE) {
Logger.i(Tags.POSITION, "correctly started map engine");
PositioningManager pm = PositioningManager.getInstance();
PositioningManager.LocationStatus ls = pm.getLocationStatus(PositioningManager.LocationMethod.GPS_NETWORK);
if (ls == PositioningManager.LocationStatus.AVAILABLE) {
Logger.i(Tags.POSITION, "Positioning is available");
} else {
Logger.w(Tags.POSITION, "Positioning not available right now " + ls.toString());
}
pm.start(PositioningManager.LocationMethod.GPS_NETWORK);
} else {
Logger.i(Tags.POSITION, "Problem setting up map engine: " + error);
}
}
});
Then I have code running once per minute on a timer to check my current position:
GeoPosition pos = PositioningManager.getInstance().getPosition();
if (pos == null) {
Log.w("Positioning", "GeoPosition is Null");
} else {
GeoCoordinate coord = pos.getCoordinate();
Logger.i("Positioning", "Location: Latitude = " + coord.getLatitude() + ", Longitude = " + coord.getLongitude());
Logger.i("Positioning", "Accuracy = " + pos.getLatitudeAccuracy() + ", " + pos.getLongitudeAccuracy());
}
When I run I get logs like this:
2019-01-27 11:49:31.960 30112-30112/com.company.app I/: [main] INFO Positioning: correctly started map engine
2019-01-27 11:49:31.961 30112-30112/com.company.app W: [main] WARN Positioning: Positioning not available right now OUT_OF_SERVICE
Then, once per minute
2019-01-27 11:50:30.850 30112-30343/com.company.app W/: [Timer-2] WARN Positioning: GeoPosition is Null
In "Settings" on the tablet "Location" is turned "On" though it says "No apps have requested Location recently"
The logs contain no Errors or warnings, all permissions are requested in the Manifest
[EDIT] The worst thing is my simple test app (mentioned in my comment below), now works after I added in the initializaion of the MapEngine. To answer HERE's question, I really am not interested in using mapping just now, I only want to pull a current Longitude and Latitude to aid in finding my tablet if lost.
Anyone have a clue what I am doing wrong?

I have a few questions to ask, the answer on which will help us to understand what is going wrong.
Do you want to show a map or just using PositioningManager?
If using PositionManager only, do you initialize MapEngine initially?
If you don't use a Map, you have to do something like this since PositionManager doesn't initialize MapEngine itself.
ApplicationContext context = new ApplicationContext(getApplicationContext());
MapEngine.getInstance().init(context, new OnEngineInitListener() {
#Override
public void onEngineInitializationCompleted(OnEngineInitListener.Error error) {
if (error == OnEngineInitListener.Error.NONE) {
} else {
}
}
});
Update: There is another test application on github that might be quite useful, no map using but position manager being used. Hope this helps!

Microsoft Face API (Android)- Add Person to Person Group

I know that this may seem to be a rather broad question, but I have been unable to figure out how to create a Person in a Person Group using the Microsoft Face API in Android Studio.
I have tried the following code to make a CreatePersonResult object in Android:
try {
CreatePersonResult person1 = faceServiceClient.createPerson(personGroupId, "Bob", "My Friends");
Toast.makeText(getApplicationContext(), "Created Person called Bob", Toast.LENGTH_LONG).show();
} catch (Exception e) {
Toast.makeText(getApplicationContext(), "Creation failed: " + e.getMessage(), Toast.LENGTH_LONG).show();
}
The above code outputs: "Creation failed: null" which means that the Exception was null for some reason.
In Visual Studio, to create a Person I simply have to do the following:
CreatePersonResult person1 = await faceServiceClient.CreatePersonAsync(personGroupId, "Bob");
Does anyone know how I can create the Person in a Person Group in Android? I have been unable to figure out how to do this in Android, but found plenty of tutorials for Visual Studio.

“Error getting Mms Carrier values” when querying Android Telephony.Carriers public class

I am having trouble obtaining the "server", "mms_proxy", and "mms_port". I haven't found anything official anywhere from Google about why this is? I would assume if this is something I cannot do then that would be stated by Google.
The Android developer website shows the Telephony.Carriers class and all that is available but says nothing about restrictions of any kind so at this point I believe it is fair to assume I can access these rather than have to ask the user to find the APN values manually which will make many people give up instantly and not use my App.
Can we please try to find an official answer as to what is going on here, I have attempted to get this information in many ways all leading to very confusing errors that seemingly cannot be explained.
I am running Android 6.01 on the device ZTE Axon 7. The lowest api that my App will allow is api_21 and the Telephony.Carriers class in available from api_19 and up.
I have declared all then necessary permission in the Manifest file and since I am currently testing on sdk "M" (Android 6), I have also acquired the permissions explicitly at Runtime from the user.
This is the code inside my Activity that I run and receive a an error stating "Error getting Mms Carrier values"...this is the whole problem and where I have become stuck.
ContentResolver contentResolver = getContentResolver();
int index_ID;
final String[] PROJECT =
{
Telephony.Carriers.TYPE,
Telephony.Carriers.MMSC,
Telephony.Carriers.MMSPROXY,
Telephony.Carriers.MMSPORT,
};
grantMyUriPermission(activity, Telephony.Carriers.CONTENT_URI, Intent.FLAG_GRANT_READ_URI_PERMISSION);
grantMyUriPermission(activity, Telephony.Carriers.CONTENT_URI, Intent.FLAG_GRANT_WRITE_URI_PERMISSION);
Cursor carriers_cursor = SqliteWrapper.query(activity, contentResolver,
Uri.withAppendedPath(Telephony.Carriers.CONTENT_URI, "current"), PROJECT, null, null, null);
if (carriers_cursor != null)
{
/*This crap below isn't needed for this situation but helps avoid ERROR*/
index_ID = carriers_cursor.getColumnIndex(Telephony.Carriers._ID);
//--------------------------------------------------------------------------------------
if (index_ID < 0 || !carriers_cursor.moveToFirst())
{
Log.i(TAG, "Error getting Mms Carrier values");
carriers_cursor.close();
return;
}
//--------------------------------------------------------------------------------------
do
{
//Confirm cursor has value assigned to it
Log.i(TAG, "cursor: "+ carriers_cursor);
//Get the available columns names
for (String item : carriers_cursor.getColumnNames())
{
//Name of each column available with Cursor
Log.i(TAG, "item: " + item);
//Attempt to get String value for each available column
try
{
//Use the name of the column, to get the index, to get the String value
Log.i(TAG, "getString(): " + carriers_cursor.getString(carriers_cursor.getColumnIndex(item)));
}
catch (Exception e)
{
Log.i(TAG, "Exception: " + e);
}
}
}
while (carriers_cursor.moveToNext());
carriers_cursor.close();
}
The Log output is:
I/SmsReceiveIntentService: Running grantMyUriPermission()
I/SmsReceiveIntentService: Running grantMyUriPermission()
I/NewConversationActivity: Error getting Mms Carrier values
And that's it! Nothing else to go on...?

Error 200 (job canceled) when streaming data from Android to BigQuery

I've been trying to build some functionality into my app too allow user-generated data (EEG recordings) to be sent to a central BigQuery database.
I've never done any networking code in Java before, so I shied away from doing the POST or REST-based strategies recommended here. The BigQuery Java client library seemed to be exactly what I needed, though I was completely confused why it wouldn't officially support Android.
Still, I came across this example Android app (from Google no less) that promised to do exactly what I wanted with the BigQuery Client library. I incorporated it into my app as follows:
// .... in an AsyncTask
#Override
protected String doInBackground(String... params) {
String CSV_CONTENT = params[0];
try {
AssetManager am = MainApplication.getInstance().getAssets();
InputStream isCredentialsFile = am.open(CREDENTIALS_FILE);
BigQuery bigquery = BigQueryOptions.builder()
.authCredentials(AuthCredentials.createForJson(isCredentialsFile))
.projectId( PROJECT_ID )
.build().service();
TableId tableId = TableId.of(DATASET,TABLE);
Table table = bigquery.getTable(tableId);
int num = 0;
Log.d("Main", "Sending CSV: ");
WriteChannelConfiguration configuration = WriteChannelConfiguration.builder(tableId)
.formatOptions(FormatOptions.csv())
.build();
try (WriteChannel channel = bigquery.writer(configuration)) {
num = channel.write(ByteBuffer.wrap(CSV_CONTENT.getBytes(StandardCharsets.UTF_8)));
} catch (Exception e) {
Log.d("Main", e.toString());
}
Log.d("Main", "Loading " + Integer.toString(num) + " bytes into table " + tableId);
} catch (Exception e) {
Log.d("Main", "Exception: " + e.toString());
}
return "Done";
}
This runs without any errors and fires off an API call that is detected by Google Cloud Storage. However, it returns error 200 (job was cancelled) every time. I don't understand how this could be since I'm not doing anything in the code to cancel the request and I don't see how the async task I put the call in could be cancelled.
Was this just a bad example app I copied and a bad usage of the BigQuery Client? If so, what's the best way to send data to BigQuery from Android?

Sony QX100 return 403 error for supported methods

I am trying to set the Exposure mode and Focus mode for my QX100 device. Each time I make the API call I get a 403 error. However, these two methods setExposureMode and setFocusMode are supported by the QX100 as it clearly states in the API docs. In addition, I can set the focus mode through Playmemories. This same problem also occurs with setBeepMode, which is also supported. Any ideas about why this could be occurring?
There are some supported methods that are working, such as actTakePicture and setPostviewImageSize
An example call:
public JSONObject setFocusMode() throws IOException {
String service = "camera";
try {
JSONObject requestJson =
new JSONObject().put("method", "setFocusMode").put("params", new JSONArray().put("MF")) //
.put("id", id()).put("version", "1.0");
String url = findActionListUrl(service) + "/" + service;
log("Request: " + requestJson.toString());
JSONObject responseJson = SimpleHttpClient.httpPost(url, requestJson, null);
log("Response: " + responseJson.toString());
return responseJson;
} catch (JSONException e) {
throw new IOException(e);
}
}

Is your QX100 updated to the latest firmware? On old one, most of APIs are restricted.
Or they may be temporary disabled. You can use getAvailableApiList to know that.
