So I am working on Nordic nrf52840 which is broadcasting extended advertising, thanks to the people on stackoverflow I can finally find my device, now the only function left is to dump extended advertising data to log, I found out that ScanResult contain may have contain the adv data I need but when I tried to dump it to log it show only {} why and how can I read adv data.

I have this problem: I'm creating a bluetooth scanner app for LE devices, in order to scan ESP32 devices. The app works perfectly, but, in some devices (like my own), the scanner gives no results.
There's no hurry, because I could test it in my father's phone and it's essentially completed. The problem is how frustrating it is, specially not knowing the cause.
Here's the ScanActivity:

As you can see, I request location and Bluetooth permissions.
Any idea?
PS:
My app goes to min sdk 27 (Android 8.1).
My device is Xiaomi Mi 9T, with Android 10. It also gives no results on Xiaomi Mi A2, Android 9&10 (it was recently updated).
The devices where it works perfectly are Samsung Galaxy J7 (Android 9) and Xiaomi Mi 8 Pro (Android 9)
You should implement onScanFailed in your ScanCallback. It might give you the reason why the scan is not working.
I am working on GoogleFit Api for daily steps count. I am getting the correct result. But when i sign out the application (In this case, app exit the Googlefit fragment's parent activity)
After sign in again, i access the same fragment again, but Googlefit returns the stepsCount as zero and getting times out at result.await.
Here is my Code.

What I was doing that I was creating the static object of the class in which I was making the googlefit client. In this case, when I exit the Activity, the object was not destroying and googlefit client was getting disconnected due to the enableAutoManage in onDestroy of the fragment. And as per my checks, I was not connecting to the googleFit client again.
I removed the object as static and now I stick the API client class object with the life cycle of the activity in which my fragment resides. Also I removed enableAutoManage and now connecting and disconnecting the API client by myself.
I have been stuck for hours . I have integrated admob ads on my application and I add it when user write something in edit text but it takes time to load ads some times it comes while some times skip .So user type the text and move to the next activity and my ads not load in time .
Can you give me some solution how to solve this issue !
thanks in advance

I've made an apache thrift server and I have a service which contains several functions.
I'm trying to figure out what is the best way to make calls to the remote server from my android application.
My problem is that I can't make calls from the MainActivity thread (the main thread) - and I need to use most of the remote functions in my main activity methods.
I tried to make a static class with a static member called "Server" equals to the server object, and I set it in another thread and then I tried to call it in the main thread (the main activity class) - but I had errors because of jumping from one thread to another..
To be more specified I want something like that:
public class MainActivity extends Activity {
private service.Client myService;
#Override
protected void onCreate(Bundle savedInstanceState) {
..
... Some stuff that define myService (In a new thread ofcourse) ...
}
...
private void MyFunc1() {
myService.Method1();
}
private void MyFunc2() {
myService.Method2();
}
private void MyFunc3() {
myService.Method3();
}
}
I've got a library for talking to REST APIs. Feel free to slice, dice, and re-use: https://github.com/nedwidek/Android-Rest-API
The code is BSD or GPL.
Here's how I use what I have (I've trimmed MainActivity a bit, hopefully not too much):

public static final String DATE_FORMAT = "yyyy-MM-dd";
protected static HashMap<String, String> headers;
static {
headers = new HashMap<String, String>();
headers.put("Content-Type", "application/json");
}
public String createUrl(String uri, HashMap<String, String> params) {
String url = baseUrl + uri + "?key=" + apiKey;
if (params != null) {
for (String hashKey: params.keySet()) {
url += hashKey + "=" + params.get(hashKey) + "&";
}
url = url.substring(0, url.length());
}
return url;
