Why do images take so long to load in this app?

Why do images take so long to load in this app? - java

I just started making an app using Google Places API. So far the app lets the user select a place and then it displays an image of the place. However, the image takes minutes to load and sometimes doesn't load at all. Please let me know if you see the error.

Send data from Android to ESP32 with Bluetooth

I've searched many tutorials on stackoverflow but can't understand anything and no one has a similar code as me.
I just want to send an "a" when i click the OFF button and "A" when i click the "ON" button. I used the OutputStream.write method but it is not working.
Here is my code:

super.onPostExecute(result);
if(result.equals("login success")) {
context.startActivity(new Intent(context, Menu.class));
}else{
alertDialog.setMessage(result);
alertDialog.show();
}
with this
super.onPostExecute(result);
if(result.equals("login success")) {
alertDialog.setMessage(result);
alertDialog.show();
}else{
alertDialog.setMessage(result);
alertDialog.show();
}
but it gave me the "login Status" from here
#Override

alertDialog = new AlertDialog.Builder(context).create();
alertDialog.setTitle("Login Status");
}

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.

Use
myListView.setOnItemSelectedListener(new OnItemSelectedListener(){
public void onItemSelected(AdapterView<?> listView, View view, int position, long id)
{
EditText yourEditText = (EditText) view.findViewById(R.id.youredittextid);
listView.setDescendantFocusability(ViewGroup.FOCUS_AFTER_DESCENDANTS);
yourEditText.requestFocus();
}
});
The problem is that the selection of the row takes the focus but in order to edit the EditText you need focus on it
