I'm trying to create a small service that connects to a site does the operations and during the process updates the textview present. Nothing wrong until I enter a for loop, because the activity stops, it becomes completely white until when it does not end.
I would like to update the text step by step.
I created an async task, but it gives me the error '
failed to load window.
Below is my code, I state that I put all the permissions.
public class GameTask extends AsyncTask<String, Integer, Long> {
private ProgressBar progressBar;
private TextView text;
public GameTask(ProgressBar progressBar, TextView text) {
this.progressBar = progressBar;
this.text = text;
}
@Override
protected Long doInBackground(String... strings) {
startGameThread(progressBar, text);
return null;
}
private void startGameThread (final ProgressBar progressBar, final TextView text) {
final Handler mHandler = new Handler();
final Runnable mRunnable = new Runnable() {
@Override
public void run() {
try {
progressBar.setProgress(0);
text.setText("Thread Iniziato...");
for (int i = 0; i <= 1000; i++) {
if (i == 0 || i % 10 == 0) {
text.setText("NUMBER " + i);
}
}
progressBar.setProgress(100);
} catch (IOException e) {
e.printStackTrace();
}
}
};
new Thread(mRunnable).start();
}
}

Don't interfere with View's inside doInBackground() method, because it is not in main thread

You can take full advantage of AsyncTask to perform tasks in background and UI thread without a Handler:
public class GameTask extends AsyncTask<String, Integer, Long> {
private ProgressBar progressBar;
private TextView text;
public GameTask(ProgressBar progressBar, TextView text) {
this.progressBar = progressBar;
this.text = text;
}
@Override
protected void onPreExecute() {
super.onPreExecute();
// UI thread
text.setText("Thread Iniziato...");
}
@Override
protected Long doInBackground(String... strings) {
// Non-UI thread
for (int i = 0; i <= 1000; i++) {
if (i == 0 || i % 10 == 0) {
publishProgress(i/100, i);
} else {
publishProgress(i/100);
}
try {
Thread.sleep(100); // Backpressure if needed for your sample
} catch (InterruptedException e) {
e.printStackTrace();
}
}
return null;
}
@Override
protected void onProgressUpdate(Integer... values) {
super.onProgressUpdate(values);
// UI thread
progressBar.setProgress(values[0]);
if (values.length > 1) {
text.setText("NUMBER " + values[1]);
}
}

As this Process is Running Inside AsyncTask, You need to Use runOnUiThread method to update the TextView. UI can only be Upated on MainThread.
private void startGameThread () {
// final Handler mHandler = new Handler();
final Runnable mRunnable = new Runnable() {
@Override
public void run() {
for (int i = 0; i <= 1000; i++) {
if (i == 0 || i % 10 == 0) {
final int finalI = i;
activity.runOnUiThread(new Runnable() {
@Override
public void run() {
textView.setText(String.valueOf(finalI));
}
});
try {
Thread.sleep(2000);
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
}
};
new Thread(mRunnable).start();
}
