i call MyTask().execute(); in onCreate() of MainAcivity Class in my application. it Busy or Hang my application for long time. please help me why? i want my work in background so that it can't disturb my app. Why my app become busy and unresponsive? Class code is below:
private class MyTask extends AsyncTask<String, Integer, String> {
// Runs in UI before background thread is called
@Override
protected void onPreExecute() {
super.onPreExecute();
// Do something like display a progress bar
}
// This is run in a background thread
@Override
protected String doInBackground(String... params) {
checkUser();
return "";
}
// This is called from background thread but runs in UI
@Override
protected void onProgressUpdate(Integer... values) {
super.onProgressUpdate(values);
// Do things like update the progress bar
}
// This runs in UI when background thread finishes
@Override
protected void onPostExecute(String result) {
super.onPostExecute(result);
// Do things like hide the progress bar or change a TextView
}
}
checkUser() method code is below
private void checkUser(){
// now here we convert this list array into json string
final String server_url="http://www.xxxx.com/TruCaller/check_user.php"; // url of server check this 100 times it must be working
// volley
StringRequest stringRequest=new StringRequest(Request.Method.POST, server_url,
new Response.Listener<String>() {
@Override
public void onResponse(String response)
{
final String result=response.toString().trim();
if(result.equals("not found")){
//Toast.makeText(MainActivity.this,"Wait...",Toast.LENGTH_LONG).show();
// Log.d("responsedd", "result not found fffffffff: "+result);
getContacts2();
}else{
}
// Log.d("responsedd", "result : "+result); //when response come i will log it
}
},
new Response.ErrorListener() {
@Override
public void onErrorResponse(VolleyError error)
{
error.printStackTrace();
error.getMessage(); // when error come i will log it
}
}
)
{
@Override
protected Map<String, String> getParams() throws AuthFailureError {
Map<String, String> params = new HashMap<String, String>();
params.put("identifier", UIDD);
Log.d("responsedd", "result not found ggggggggggg: "+ UIDD);

}
};
Vconnection.getnInstance(this).addRequestQue(stringRequest); // vConnection i claas which used to connect volley

MainAcivity onCreate Method :
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
new MyTask().execute();}
Solution
i try below code instead of new MyTask().execute() class. and the below code work for me. i also try below code with xxx.run(); method instead of start();. run() method also not work. only thread with xxx.start(); worked. so the correct code is below one. Thanks every one.
new Thread(new Runnable(){
@Override
public void run() {
//my method
checkUser();
}
}).start();
