ProgressDialog quits updating when orientation of screen changes. I have put into place a fix that salvages the asynctask and sets the activity of the asynctask to the new activity after it is destroyed and rebuilt. The percentage complete on the progressdialog stays at the percentage it was at before the orientation change.
What am I missing?

This is not a real solution but to prevent this I just disabled orientation changes during the life of the AsyncTask with adding first:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_NOSENSOR);
and when the job is done:
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_SENSOR);
Hope this helps.

This is such a basic issue that I am not sure what I could possibly be doing wrong. Sinch is not starting for me and I don't know why. I don't have enough experience with Sinch to diagnose why a basic command is not doing what it is supposed to do. Here's what I have:
I am trying to start and making the call from the Calling.java class. The code is as follows:
import android.content.Intent;
import android.os.Bundle;
import android.widget.Button;
import android.widget.ImageView;
import android.widget.TextView;
import com.sinch.android.rtc.calling.Call;
import com.squareup.picasso.Picasso;
import static android.content.Intent.FLAG_ACTIVITY_PREVIOUS_IS_TOP;
public class Calling extends CallActivity {
private String calleeID;
private TextView serviceName;
Bundle callDetails;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_calling);
callDetails = getIntent().getBundleExtra("callDetails");
//Setup end button
Button endCallButton = findViewById(R.id.endcall);
endCallButton.setOnClickListener(v -> endCall());
}
private void endCall() {
if (getSinchServiceInterface() != null) {
getSinchServiceInterface().stopClient();
}
finishActivity(FLAG_ACTIVITY_PREVIOUS_IS_TOP);
finish();
}
// invoked when the connection with SinchServer is established
#Override
protected void onServiceConnected() {
//Setup Calling Screen
ImageView avatar = findViewById(R.id.dialingAvatar);
Picasso.get().load(callDetails.getString("Logo")).into(avatar);
TextView midScreenName = findViewById(R.id.memberName);
midScreenName.setText(callDetails.getString("Name"));
serviceName = findViewById(R.id.serviceName);
serviceName.setText(callDetails.getString("Service"));
TextView ratings = findViewById(R.id.rating);
ratings.setText(callDetails.getString("Rating") + " ★");
//Get CallerID and CalleeID
calleeID = callDetails.getString("CalleeID");
//Start sinch Service
if(!getSinchServiceInterface().isStarted()){
getSinchServiceInterface().startClient(callDetails.getString("CallerID"));
Call call = getSinchServiceInterface().callUserVideo(calleeID);
Intent callServiceScreen = new Intent(this, ServiceCallActivity.class);
callDetails.putString(SinchService.CALL_ID, call.getCallId());
callServiceScreen.putExtra("Call Details", callDetails);

I have been banging my head against this but I cannot figure out what's wrong. I sure it's something stupid and obvious that I can't see because I am too close to the code. But any ideas you guys have would be very helpful!
It looks like you are not waiting for it to start before you try to make a call. We recommend to start the service when the app starts. If you dont do that you need to wait or the onStarted event in the service for fire
I am trying to update a progress bar while downloading a file, but in my Service task I do not have any access to the UI. This means I cannot find the ProgressBar element using findViewByID in order to update the ProgressBar. Here is the relevant code:
MainActivity:
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.content.Intent;
import android.view.View;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
public void startService(View view) {
startService(new Intent(getBaseContext(), MyService.class));
}
public void stopService(View view) {
stopService(new Intent(getBaseContext(), MyService.class));
}
}

import android.widget.ProgressBar;
import android.widget.Toast;
import java.net.MalformedURLException;
import java.net.URL;
import android.os.AsyncTask;
import android.util.Log;
import java.util.Timer;
import java.util.TimerTask;
public class MyService extends Service {
int counter = 0;
static final int UPDATE_INTERVAL = 1000;
private Timer timer = new Timer();
#Override
public IBinder onBind(Intent arg0) {
return null;
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {

} catch (MalformedURLException e) {

}
return START_STICKY;
}
#Override

}

}
private void doSomethingRepeatedly() {
timer.scheduleAtFixedRate(new TimerTask() {
public void run() {
Log.d("MyService", String.valueOf(++counter));
}
}, 0, UPDATE_INTERVAL);
}
private class DoBackgroundTask extends AsyncTask<URL, Integer, Long> {
protected Long doInBackground(URL... urls) {
int count = urls.length;
long totalBytesDownloaded = 0;
for (int i = 0; i < count; i++) {
totalBytesDownloaded += DownloadFile(urls[i]);
publishProgress((int) (((i + 1) / (float) count) * 100));
}
return totalBytesDownloaded;
}

Log.d("Downloading files", String.valueOf(progress[0]) + "% downloaded");
Toast.makeText(getBaseContext(),
String.valueOf(progress[0]) + "% downloaded-"+counter,
Toast.LENGTH_LONG).show();
}
protected void onPostExecute(Long result) {
Toast.makeText(getBaseContext(), "Downloaded " + result + " bytes",
Toast.LENGTH_LONG).show();
//stopSelf();
}
}
private int DownloadFile(URL url) {
try {
//---simulate taking some time to download a file---
Thread.sleep(5000);
} catch (InterruptedException e) {
e.printStackTrace();
}
//---return an arbitrary number representing
// the size of the file downloaded---
return 100;
}
}
Basically, I want to update the ProgressBar in my MainActivity by using the bytesDownloaded variable in my MyService class, but I'm not sure how to handle the Async call in my MainActivity. If that is even possible.
Thanks!
I am trying to update a ProgressBar from a Service task. I implemented a BroadcastReceiver so that I can interact with the UI thread. I update the ProgressBar in the main activity, and receive the data from the MyService activity. The MyService activity executes an Async task and updates the intent that should be sent back in the OnProgressUpdate method.
Here is my code:
MainActivity:
package com.example.services;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.IntentFilter;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.content.Intent;
import android.view.View;
import android.widget.ProgressBar;
import static android.content.Intent.ACTION_ATTACH_DATA;
public class MainActivity extends AppCompatActivity {
private MyBroadRequestReceiver receiver;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
IntentFilter filter = new IntentFilter(ACTION_ATTACH_DATA);
receiver = new MyBroadRequestReceiver();
registerReceiver( receiver, filter);
}
public void startService(View view) {
startService(new Intent(getBaseContext(), MyService.class));
//pb.setProgress();
}
public void stopService(View view) {
stopService(new Intent(getBaseContext(), MyService.class));
}
public class MyBroadRequestReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent) {
ProgressBar pb = (ProgressBar) findViewById(R.id.progressbar);
int progress = intent.getFlags();
pb.setProgress(progress);
}
}
}

Please take a look at my onProgressUpdate and tell me if I am doing this correclty. My ProgressBar is not being updated at all.
Because you don't startService ononCreate() Method. Service will not run.
Firs of all this is not good solution to the problem your solving. Please go through Google Android docs Backgournd guide
I suggest you should switch to DownloadManager.
Your intent filter is defining to "ACTION_ATTACH_DATA"
IntentFilter filter = new IntentFilter(ACTION_ATTACH_DATA);
So, send your broadcast like this:
Intent i = new Intent(ACTION_ATTACH_DATA);
sendBroadcast(i);
Also, don't forget to unregister the broadcast at onDestroy
Ok,
I'm doing this for 4 straight hours. And the facebook Login still doesn't work. The session state is always OPENING. ALWAYS. onActivityResult NEVER gets called. The key in the developer console is correct, the starting class is correct, and this is my code

What did I forget?
Apparently it is not allowed to have
android:noHistory="true" in your manifest. I removed it and now it works.
Hi I have created download process activity and it's run on button click. This activity opens on listitem click. But Now I want to run the download process on lisitem click, instread of button click.
ZipDownloader.java
import java.io.File;
import android.app.Activity;
import android.app.ProgressDialog;
import android.os.AsyncTask;
import android.os.Bundle;
import android.view.View;
import android.view.WindowManager;

import com.kabelash.sg.R;
public class ZipDownloader extends Activity {
protected ProgressDialog mProgressDialog;
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate( savedInstanceState );
setContentView( R.layout.zipdownload );
// Keep the screen (and device) active as long as this app is frontmost.
// This is to avoid going to sleep during the download.
getWindow().addFlags( WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON );
}
/**
* Invoked when user presses "Start download" button.
*/
public void startDownload( View v ) {
String url = "http://sample.co.uk/sample.zip";
new DownloadTask().execute( url );
}
/**
* Background task to download and unpack .zip file in background.
*/
private class DownloadTask extends AsyncTask<String,Void,Exception> {
#Override
protected void onPreExecute() {
showProgress();
}
#Override
protected Exception doInBackground(String... params) {
String url = (String) params[0];
try {
downloadAllAssets(url);
} catch ( Exception e ) { return e; }
return null;
}
}
//Progress window
protected void showProgress( ) {
mProgressDialog = new ProgressDialog(this);
mProgressDialog.setTitle( R.string.progress_title );
mProgressDialog.setMessage( getString(R.string.progress_detail) );
mProgressDialog.setIndeterminate( true );
mProgressDialog.setCancelable( false );
mProgressDialog.show();
}
protected void dismissProgress() {
// You can't be too careful.
if (mProgressDialog != null && mProgressDialog.isShowing() && mProgressDialog.getWindow() != null) {
try {
mProgressDialog.dismiss();
} catch ( IllegalArgumentException ignore ) { ; }
}
mProgressDialog = null;
}
}
on MainActivity.java
#Override
public boolean onOptionsItemSelected(MenuItem item) {
super.onOptionsItemSelected(item);
switch(item.getItemId()){
case R.id.update:
Intent intent = new Intent(this, ZipDownloader.class);
startActivity(intent);
break;
}
return true;
}
Please don't ignore this question. Thanks in advance and sorry for my English.
Have you tried bringing your AsyncTask code into the activity you want your listitem clicked, then just
switch(item.getItemId()){
case R.id.update:
String url = "http://sample.co.uk/sample.zip";
new DownloadTask().execute( url );
break;
}
return true;
call the background task onclick?
