How to increase speed of BLE scanning Android Studio?

I want make some application, it will scanning nearby BLE and sending to server via MQTT. But the scanning proccess to slow. I want to increase the speed of scanning.

How to increase speed of scanning nearby BLE? i expect from this forum, i can increase speed of scanning nearby BLE.

I am making OCR Reader Application. When I create the PDF of generated text, it is not saved as I want. There is one problem in the while loop

To save this PDF I have added a while loop where the last letter has added a specific number from 0 to n in parentheses. When I save the first PDF it is saved as myPDFfile.pdf then the second pdf will be saved as myPDFFile(1).pdf but when I save the third pdf it will be saved as myPDFFile(1)(1).pdf
but I want this pdf to save as myPDFfile(2).pdf.

Send and receive json obj in Android

I am currently working with an app that can access an online game to acquire information of my account. I need to use JSON to communicate with the server. I used the following code to try to communicate with the server, but there are no responds from the server. I also noticed that the httpclient and some other popular class were deprecated and I can't find some proper tutorial to teach me on this topic. Any help is appreciated.

I don't think you should encode the body of the message.
The reason it is called "URLEncoder" is because it is used to encode a URL but this is the body of your message.
Also, the internal try block you have is redundant and also you should change the request method to GET in the middle of the request.
There's no need to flush the bytes.
Remember that with a POST request, nothing is sent until you read the response using your InputStream.

You should use Volley Library for it.
It's very good for the Rest API's.
And managing server calls is simple with it.
Add the library by compiling
compile 'com.android.volley:volley:1.0.0'
then make a Singleton class to handle all the volley requests.
Volley provides JsonArrayRequest and JsonObjectRequest which are very helpful during network calls.
Here is volley singleton class
public class MyApplication extends Application
{
private RequestQueue mRequestQueue;
private static MyApplication mInstance;
#Override
public void onCreate()
{
super.onCreate();
mInstance = this;
}
public static synchronized MyApplication getInstance()
{
return mInstance;
}
public RequestQueue getReqQueue()
{
if (mRequestQueue == null)
{
mRequestQueue = Volley.newRequestQueue(getApplicationContext());
}
return mRequestQueue;
}
public <T> void addToReqQueue(Request<T> req, String tag)
{
getReqQueue().add(req);
}
public <T> void addToReqQueue(Request<T> req)
{
getReqQueue().add(req);
}
public void cancelPendingReq(Object tag)
{
if (mRequestQueue != null) {
mRequestQueue.cancelAll(tag);
}
}
}
Add this to your application tag in manifest
<application
android:name="MyApplication">
This is a sample JsonObjectRequest
JsonObjectRequest request = new JsonObjectRequest("requestMethod","url","input_data",
new Response.Listener<JSONObject>()
{
#Override
public void onResponse(JSONObject response)
{
}
},
new Response.ErrorListener()
{
#Override
public void onErrorResponse(VolleyError error)
{
}
});
MyApplication.getInstance().addToReqQueue(request);

It could be as simple as your AdView not actually being on screen. The AdView is contained within a ScrollView so there is no guarantee that it is actually on screen.
You have a complicated view hierarchy. Suggest you simplify it and move the AdView outside of your ScrollView.
