ProgressDialog spinner not spinning in AsyncTask (On some devices)

This is my AsyncTask that is being executed when I click an item in a ListView. I display a ProgressDialog while the task is running and dismiss it at the end of onPostExecute() as shown below. This works and the spinner displays in my Nexus 5X emulator. On any other emulator or my real device (Galaxy S7 Edge Nougat) however, the dialog shows but without a spinner or with the spinner but it instantly freezes. I HAVE turned on all transitions/animations to 1x in the developer options by the way and all my other animations work so I know that is not the issue.

Create a variable to store the select interval. Move the mHandlerTask and startRepeatingTask method outside onCreate. Inside the onClick call startRepeatingTask method.
See the code below,
private final static int SELECTED_INTERVAL = 0;
#Override
protected void onCreate(Bundle savedInstanceState) {
...
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if(rd1.isChecked()) {
SELECTED_INTERVAL = INTERVAL;
} else if (rd2.isChecked()) {
SELECTED_INTERVAL = INTERVAL2;
}
stopRepeatingTask();
startRepeatingTask();
}
});
}
void startRepeatingTask() {
mHandlerTask.run();
}
void stopRepeatingTask() {
mHandler.removeCallbacks(null);
}
Runnable mHandlerTask = new Runnable() {
#Override
public void run() {
new WallpaperData().execute();
mHandler.postDelayed(mHandlerTask, SELECTED_INTERVAL);
}
};
#Override
public void onDestroy() {
super.onDestroy();
stopRepeatingTask();
}

Activity hangs on TextView.setText()

Code first:
public class MyActivity extends Activity {
Button send;
TextView textv;
String answer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_activity);
send = (Button)findViewById(R.id.sendButton);
textv = (TextView)findViewById(R.id.textViewv);
send.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
MyClientTask myClientTask = new MyClientTask("localhost", 1234, "QUESTION");
myClientTask.execute();
}
});
}
void processAnswer() {
Log.i("DEBUG", "in processAnswer - before setting text");
Log.i("DEBUG", "ANSWER");
textv.setText("ANSWER\n"); // <-------- H E R E -----------
Log.i("DEBUG", "in processAnswer - after setting text");
}
public class MyClientTask extends AsyncTask<Void, Void, Void> {
String dstAddress;
int dstPort;
String message;
String response;
MyClientTask(String addr, int port, String msg){
dstAddress = addr;
dstPort = port;
message = msg;
response = "";
}
#Override
protected Void doInBackground(Void... arg0) {
Socket socket = null;
try {
InetAddress serverAddr = InetAddress.getByName(dstAddress);
socket = new Socket(serverAddr, dstPort);
OutputStream out = socket.getOutputStream();
out.write(message.getBytes());
out.flush();
String msgrc = "";
int charsRead = 0;
char[] inputBuf = new char[4096];
InputStream is = socket.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader in = new BufferedReader(isr);
while ((charsRead = in.read(inputBuf)) != -1) {
msgrc += new String(inputBuf).substring(0, charsRead);
}
// outer class variable
MyActivity.this.answer = msgrc;
out.close();
is.close();
socket.close();
Log.i("DEBUG", "before processing answer");
MyActivity.this.processAnswer();
Log.i("DEBUG", "after processing answer");
} catch (Exception e) {
}
return null;
}
}
}
The code above simply sends some message to a server and receives an answer. This answer should then be displayed in the TextView (see marked line). However, the app hangs at that line, i.e, LogCat displays
[...]
before processing answer
in processAnswer - before setting text
ANSWER
Then no more lines are written to LogCat. Has anybody an explanation for that? If the marked line is commented out, LogCat looks like
[...]
before processing answer
in processAnswer - before setting text
ANSWER
in processAnswer - after setting text
after processing answer

If you move your call to MyActivity.this.processAnswer() to onPostExecute() instead, perhaps that might work - IIRC, items on the UI thread should only be updated from the UI thread.

First inialize your text view by following , then add onPostExecute method bellow the doInBackground
method . And set your text there . Bellow is code which i change.
public class MyActivity extends Activity {
Button send;
TextView textv;
String answer;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.my_activity);
send = (Button)findViewById(R.id.sendButton);
textv = (TextView)findViewById(R.id.textview);
send.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
MyClientTask myClientTask = new MyClientTask("localhost", 1234, "QUESTION");
myClientTask.execute();
}
});
}
public class MyClientTask extends AsyncTask<Void, Void, Void> {
String dstAddress;
int dstPort;
String message;
String response;
MyClientTask(String addr, int port, String msg){
dstAddress = addr;
dstPort = port;
message = msg;
response = "";
}
#Override
protected Void doInBackground(Void... arg0) {
Socket socket = null;
try {
InetAddress serverAddr = InetAddress.getByName(dstAddress);
socket = new Socket(serverAddr, dstPort);
OutputStream out = socket.getOutputStream();
out.write(message.getBytes());
out.flush();
String msgrc = "";
int charsRead = 0;
char[] inputBuf = new char[4096];
InputStream is = socket.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader in = new BufferedReader(isr);
while ((charsRead = in.read(inputBuf)) != -1) {
msgrc += new String(inputBuf).substring(0, charsRead);
}
// outer class variable
MyActivity.this.answer = msgrc;
out.close();
is.close();
socket.close();
Log.i("DEBUG", "before processing answer");
MyActivity.this.processAnswer();
Log.i("DEBUG", "after processing answer");
} catch (Exception e) {
}
return null;
}
#Override
protected void onPostExecute(Void result) {
// TODO Auto-generated method stub
super.onPostExecute(result);
textv.setText(msgrc);
}
}
}

Executing code by a onClick event on another thread

I'm developing an application which pulls weather data from a MySQL database by using PHP and JSON. It checks wether the user has an internet connection, if not then it will look for a file stored locally. If that file doesn't exists then it will display a message. To refresh the list, the user has to restart the application. I found this not really user-friendly so I decided to add a button which refreshes the data.
I have two classes, my ListActivity class (called WeerActivity.java in the code below) and a class which gathers all the data from the internet in a new thread (called InternetWeerThread.java). My onClickListener, for the refresh button, is set up in the ListActivity class. This tries to post a runnable to the other class, containing the refresh code. However when I do this. I get an exception because the code is still executed on the UI-Thread.
WeerActivity.java

Internet connection is a blocking action, i.e. it blocks the UI until the action is complete (this is why only the last update is seen). You have to move it to a Thread (or even better to an AsyncTask). But then you get another problem, you cannot update UI from outside the main Thread. So, you have to use a Handler to update the UI.

You are executing a network operation on main thread, point to understand here is Android operates upon single main thread so if you do any time consuming operation on Service/Activity/Content Providers etc, it will block your main thread and hence all the stuff will look like they are blocked/un-responsive infact you will receive an ANR message after few seconds.
to conclude, follow this approach
Move your network extensive code to a separate thread
Implement a Mesasge handling mechanism to update your UI on main thread (Handler/Looper)
to help out things further Android provides you a class AsynTask for this purpose. You can do your operation in doInBackground() and upon condition you can update you UI through onProcessUpdate()
hope this helps.

If you run this process on UI thread it may cause to prompt a dialog saying "Applicaiton
not responding".So I recommend this task must be done either in AsyncTask or Service
U can update your text view in
onPreExecute()
onProgressUpdate()
onPostExecute() functions in AsyncTask.
Eg.for downloading file
private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> {
protected Long doInBackground(URL... urls) {
int count = urls.length;
long totalSize = 0;
for (int i = 0; i < count; i++) {
totalSize += Downloader.downloadFile(urls[i]);
publishProgress((int) ((i / (float) count) * 100));
// Escape early if cancel() is called
if (isCancelled()) break;
}
return totalSize;
}
protected void onProgressUpdate(Integer... progress) {
setProgressPercent(progress[0]);
}
protected void onPostExecute(Long result) {
showDialog("Downloaded " + result + " bytes");
}
}
