Hi I developed an app using HMS core SDK for HD Location API.
PRIORITY_HD_ACCURACY = 200;
// Precise location session Used API:
https://developer.huawei.com/consumer/en/doc/development/HMS-References/fusedlocationproviderclient#11
I am gettinglocations, but when I checked the Source Type
int source = location.getExtras().getInt("SourceType", 0);
Source type is coming as 19 and 128 where last but three bits are not 1.
Please help me in this why locations are not from HD_ACCURACY API.
LocationupdateEx() only use in China therefore, you cannot obtain PRIORITY_HD_ACCURACY data

Does anyone know what is maximum size to upload file via Azure HDFS Rest API? (https://learn.microsoft.com/en-us/azure/data-lake-store/data-lake-store-data-operations-rest-api).
I found someplace 256MB, some place 32MB, so wondering.
Or similar limits for other SDKs?
I was wrestling with the same problem some months ago and it turned out that the IIS which is in front of ADLS is setting the maxAllowedContentLength with default value of 30000000 bytes (or 28.6Mb). This essentially means that whenever we want to push anything bigger that 30Mb, that request never reaches ADL as IIS throws 404.13 before that. Reference.
As already suggested in the links, ADLS has a driver with a 4-MB buffer, I'm using the .NET SDK myself and following code has served me well
public async Task AddFile(byte[] content, string path)
{
const int fourMb = 4 * 1024 * 1024;
var buffer = new byte[fourMb];
using (var stream = new MemoryStream(content))
{
if (!_adlsFileSystemClient.FileSystem.PathExists(_account, path))
{
_adlsFileSystemClient.FileSystem.Create(_account, path);
}
int bytesToRead;
while ((bytesToRead = stream.Read(buffer, 0, buffer.Length)) > 0)
{
if (bytesToRead < fourMb)
{
Array.Resize(ref buffer, bytesToRead);
}
using (var s = new MemoryStream(buffer))
{
await _adlsFileSystemClient.FileSystem.AppendAsync(_account, path, s);
}
//skipped for brevity
In my tests, I am finding a maximum file size limit somewhere between 28MB and 30MB.
Using the Azure Data Lake Storage REST API, I have had no issues creating files as large as 28MB. However, when I try to create a file that is 30MB, I receive a 404 Not Found error.
The following references align with the file size limit and 404 error I am observing. The references are about the SDK, but it could be that the SDK is also calling the REST API under the covers. My tests are calling the REST API directly.

Hi I am developing an application in BlackBerry 10 platform which will calculate data usage and voice usage of user device for particular duration.
There are some of the feasibility check need to be done for this which are as follows
Does BB10 API supports data usage calculation? If yes, Can I differentiate 3G/Cellular data from WiFi data?If yes, how can I achieve this?
How can I calculate Voice usage in BB 10 application? Voice usage is nothing but duration of all calls happened within particular timespan
Is there any API BB10 provides through which I can check if device is currently in Roaming or not?
Please let me know if this can be done in BB 10 application
Does BB10 API supports data usage calculation?
Yes, there are a few for API's for this
Can I differentiate 3G/Cellular data from WiFi data?
Yurp you can.
1) Add the following line to your .pro file:
LIBS += -lbbdevice
2) Make sure you include:
#include <bb/device/NetworkDataUsage>
3) Getting data useage for cellular network only
bb::device::NetworkDataUsage *nduCell = new bb::device::NetworkDataUsage("cellular0");
nduCell ->update();
quint64 bytesSent = nduCell ->bytesSent();
quint64 bytesReceived = nduCell ->bytesReceived();
4) Getting data useage for wifi only
bb::device::NetworkDataUsage *nduWifi = new bb::device::NetworkDataUsage("tiw_sta0");
nduWifi ->update();
quint64 bytesSent = nduWifi ->bytesSent();
quint64 bytesReceived = nduWifi ->bytesReceived();
That will give your the data useage since the device has started.
You will need to call ndu->update() regularly to get the most recent data usage statistics.
Extra Info:
Changing the parameter for the NetworkDataUsage changes the interface it minitors:
cellular0 == Cellular
tiw_sta0 == Wifi
ecm0 == USB
To find out which interfaces are available on your device:
1) Add the following line to your .pro file:
QT += network
2) Make sure you include:
#include <QNetworkInterface>
3) Displaying available interfaces
QList<QNetworkInterface> interfaces = QNetworkInterface::allInterfaces();
for (int i = 0; i < interfaces.size(); i++) {
qDebug() << QString::number(i) + ": " + interfaces.value(i).humanReadableName();
}
How can I calculate Voice usage in BB 10 application? Voice usage is nothing but duration of all calls happened within particular timespan
This can be done using Phone class.
There is signal call void callUpdated (const bb::system::phone::Call &call, ) using which we can get to know if incoming call is received or outgoing call is initiated.
With the combination of this and Timer class we can calculate Voice usage of device. (This code is not tested)
i want to write an application to fetch call history from a black berry 10.
Can any body guide me which API i can use.
From the above link we can only display the default call log.
Would using the invocation framework work for what you are trying to do? It seems there is a way to fetch the call log.
https://developer.blackberry.com/cascades/documentation/device_platform/invocation/phone.html
This can be done using the CallHistoryService API available in OS 10.3.0
Here is some sample code to fetch all calls and output the numbers to the log:
CallHistoryService callHistoryService;
// The ID of a valid account is required
bb::pim::account::Account defaultAccount =
callHistoryService.defaultAccount();
// The default filter will return all calls
CallHistoryFilter defaultFilter;
// Contact search can be used to identify the contacts
CallHistoryParam callHistoryParams;
callHistoryParams.setContactSearchEnabled(false);
QList<CallEntryResult> callHistoryResults =
callHistoryService.callHistory(
defaultAccount.id(),
defaultFilter,
callHistoryParams);
foreach (const CallEntryResult &callEntryResult, callHistoryResults) {
CallEntry callEntry = callEntryResult.call();
qDebug << "Phone number: " << callEntry.phoneNumber();
}
Every iPhone has a NORID (8 bytes) & CHIPID (12 bytes) unique to each phone.
Where is this stored? NOR? seczone? Can it be dumped?
An iPhone requires a NCK to unlock. From what I understand the NCK is 15 characters.
Is it numeric, alpha or alphanumeric?
The security token for check if the NCK is valid is stored encrypted at +0x400 in the seczone.
Is this correct?
Based on what I've read from dogbert's blog, the security token is created using a method similar to the following pseudo code:
deviceKey = SHA1_hash(norID+chipID)
nckKey = custom_hash(norID, chipID, SHA1_hash(NCK), deviceKey)
rawSignature = generateSignature(SHA1_hash(norID+chipID), SHA1_hash(chipID))
Signature = RSA_encrypt(rawSignature, RSAkey)
security token = TEA_encrypt_cbc(Signature, nckKey)
Is the pseudocode correct? If it is then what is the custom hash that is being used? What is being used to generate the rawSignature? What is the RSAKey that is being used? Is it a public key that can be found in the phone?
If the above pseudocode is CORRECT. Then we would have to bruteforce all 15 character combinations to find the correct NCK key right? Because, even though we are able to recover the NORID and CHIPID, we will not be able to use that information to shorten the amount of characters which we need to find.
Correct?
New generations of iPhone OS contains a wildcardticket that is generated during activation process.
but this should be no problem generating once we have the NCK right? Correct?
The NOR ID is the hardware chip id burned into the baseband chip of the device. I don't know where you are getting the 8 bytes from but it is actually burned into the chip and the size is 64 bytes for iPhone 3G and 128 bytes for the iPhone 3GS.
The NCK is a 15 digit (base 10 so it is not alpha-numeric). ie. the max NCK would be 999999999999999
Your device key is wrong.
It should read:
deviceUniqueKey = SHA(NCK + CHIPID + NORID)
teaEncryptedData = &seczone[0x400]
rsaEncryptedData = TEA_DECRYPT(teaEncryptedData, deviceUniqueKey)
validRSAMessage = RSA_DECRYPT(rsaEncryptedData, rsaKey)
When your NCK produces a valid RSA message, you have found the correct NCK to unlock your device.
Here is the python script that can decrypt iPhone baseband memory so you will be able to get all NCK tokens like
CHIP ID
NOR ID
IMEI hushes
Tea hashes
But this script was used only for old basebands (S-Gold chipset) but you can always make your own.
Also here are some ways to dump iphone baseband into the file by using iPhone core dump function or by other script like NOR dumper. Hope this help
Looking for a sample code or tutorial to fetch few transmission parameters like
1. RXlevel (Signal Strength)
2. RXQual (Bit Error Rate)
3. C/I (carrier to interference)
4. FER (Frame erase rate
6. towers location.
7. Radio access technology
8. mobile country code
9. mobile network code
10. location code area
11. CELL ID
12. absolute RF channel number
13. base station identity code
13. RSSI
14. C1 hand-over parametr
15. CELLS information for example:
a. absolute RF channel number.
b. base station identity code
c. RSSI
I noticed a application Signal which must be using something similar, but since it only works on Jailbroken devices I understand it is using private API. Can anyone recommend which private framework can provide this information.
Look at CoreTelephony, but it only gives a few things (mobile country code, mobile network code) Apple Docs for CoreTelephony see CTCarrier class.
