How to properly stop all the threads in Android?

How to properly stop all the threads in Android? - java

In the code below, I maintain the "isFound" boolean variable to determine whether a thread should run or not. However, when I set the "isFound" to true. My threads will run exactly one more time. In other words, they will not stop properly which also causes the UI to not update the Textview properly. I guess this is due to some synchronized problems but I am not sure how to deal with it and I have tried using a synchronized block but it still does not work.

How do I end a repeating handler when it hits a certain condition?

I'm making an application that plays audio files off the device's storage, and I have a seek bar that checks the progress of the audio file (how long it has played) every second, and updates the seekbar accordingly.
The audio is played through a service that runs in the foreground, and also displays a notification that the audio is playing.
When the audio ends, I noticed the handler still goes in it's cycle, and I want to end the handler once the audio is done.
What I'm currently trying to do is to end the handler from inside the runnable that the handler runs, as I'm not sure how else I can end it.
Main Activity, where I handle OnClick from the ListView where you can select an audio file and also handles the seekbar update.

}
#Override

{
unbindService(serviceConnection);
progBarHandler.removeCallbacks(r);
super.onDestroy();
}
}
What is strange is that in onDestroy(), I do use removeCallbacks to end the handler, and that works nicely. I know that it comes to the point where it calls for removeCallbacks in the Runnable r, confirmed through debugging and logging. Also tried implementing a method that is specifically for removing the handler and calling that, no luck. Also tried using return.
The part I'm struggling with is
r = new Runnable()
{
#Override
public void run()
{
int tempInt = myService.fetchProgress();
Log.d("progress ticking", tempInt + " " + musicProgBar.getProgress());
musicProgBar.setProgress(tempInt); // sets the current progress of the seekbar to be the progress of the song
long minutes = TimeUnit.MILLISECONDS.toMinutes(tempInt);
long seconds = TimeUnit.MILLISECONDS.toSeconds(tempInt);
if (seconds >= 60)
seconds = seconds % 60;
String tempString = minutes + ":" + seconds;
progressText.setText(tempString);
progBarHandler.postDelayed(this, progBarDelay);
if (musicProgBar.getProgress() == myService.fetchDuration())
progBarHandler.removeCallbacks(this);
}
};
progBarHandler.post(r);
}});

Thanks in advance for any help, and I am happy to provide with more information if required
EDIT: changed the progBarHandler.postDelay() that is outside the runnable to a simple progBarHandler.post()

I think the only reason you failed to stop the handler is constantly invoking progBarHandler.postDelayed(this, progBarDelay);,you need to check why it's still running.

Managed to get it working by introducing a different kind of if statement to the runnable, like so
Runnable r = new Runnable()
{
#Override
public void run()
{
if (musicProgBar.getProgress() == myService.fetchProgress() && myService.fetchProgress() != 0)
Log.d("audio", "over");
else {
int tempInt = myService.fetchProgress();
long minutes = TimeUnit.MILLISECONDS.toMinutes(tempInt);
long seconds = TimeUnit.MILLISECONDS.toSeconds(tempInt);
if (seconds >= 60)
seconds = seconds % 60;
String tempString = minutes + ":" + seconds;
progressText.setText(tempString);
musicProgBar.setProgress(tempInt); // sets the current progress of the seekbar to be the progress of the song
progBarHandler.postDelayed(this, progBarDelay);
}
}
};
It seemed for some reason, using .fetchDuration() and .fetchProgress() will never equalize each other, so changing the if statement worked.

My application is working in an endless loop

So I have an application which has to monitor and range after beacons and than calculates the position of the user. After calculating this , the value is passed to the Wayfindigoverlayactivity.class where the value should be putt on the map with the blue dot.
I don know how to assign the value to the blue dot but before that my application is working on an endless loop and is opening the activity on ranging about 100x .

The second class is not fully posted , only where I make changes.
The intent in the second class is in the OnCreate part
The location is calculated in the logcat , the only problem is that the application is working in a loop
Please help me , I am stuck. Thanks

I guess, you only need to open RangingActivity from onCreate() of WayFindingOverlayActivity if center is null. This means, we need to open RangingActivity to get the value for center. Doing null check for the center will also ensure that the application doesn't go in loop and proceed when we have the value for center. The code in the onCreate() of WayFindingOverlayActivity may look like this :
// edited here
Bundle extras = getIntent().getExtras();
if(extras == null){
Intent myIntent = new Intent(this, RangingActivity.class);
this.startActivity(myIntent);
} else{
LatLng center = extras.getParcelable("b");
Log.d("Location!!", center);
// call showLocationCircle() to show the blue dot
showLocationCircle(center, yourAccuracyRadius);
}

Trying to process different scenarios in Service

I am having a problem and I ran out of ideas how to fix it.
The goal is, when the user clicks the button an URL is loaded depending on what's selected in settings.
Problem is, I am having trouble setting it up in a right way.
Logically(to me), I tried to set it up in a service. Button is clicked > Service starts > URL is loaded from "IF ELSE".
Problem is, I get an error in "IF ELSE" - "Method length must be called from the UI Thread, currently inferred thread is is worker.
public static class Service extends IntentService {
public Service() {
super("wallpaperchanger-download");
}
#Override
protected void onHandleIntent(Intent intent) {
MainActivity mainActivity;
mainActivity = new MainActivity();
if (mainActivity.mEditTextHashtag.length() > 2) {
WallpaperManager wm = WallpaperManager.getInstance(this);
int height = wm.getDesiredMinimumHeight();
int width = wm.getDesiredMinimumWidth();
String url = "https://source.unsplash.com/all/?" + mainActivity.mEditTextHashtag.getText() + "/" + width + "x" + height + "/";
try {
InputStream input = new URL(url).openStream();
Log.v(TAG, url);
wm.setStream(input);
input.close();
} catch (Exception e) {
e.printStackTrace();
}
loading = false;
}
}
}
Ok, fair enough.
I created new Method getPhoto(); in UI Thread and put the code in there. Then, I called mainActivity.getPhoto(); in Service.
Problem is, I get an error - "Attempt to invoke virtual method 'int android.widget.EditText.length()' on a null object reference"
Any ideas on what I should do?

Thanks :)

First of all, you should never instantiate an activity by yourself.
Second, as a best practice, your service shouldn't know about your activity, or that it has an edit text. Instead you should send the URL to load inside your intent, when the PendingIntent is created, like this :
Intent intent = new Intent("com.edip.splashwallpaper.CHANGE_WALLPAPTER_TIMER");
intent.putExtra("USER_URL", "https://source.unsplash.com/all/?" + mEditTextHashtag.getText() + "/" + width + "x" + height + "/");
PendingIntent pending = PendingIntent.getBroadcast(MainActivity.this,
666, intent, PendingIntent.FLAG_CANCEL_CURRENT);
Then within your service, read the url like so :
#Override
protected void onHandleIntent(Intent intent) {
String url = intent.getStringExtra("USER_URL");
// ...
}

Output every minute for ten minutes

I am trying to print something out for an android app every minute for ten minutes. I would preferably like to access the phone's clock to have the code start automatically at a specific time. However, I am not exactly sure how to do that part. Here is what I have so far.
So here is my main code I want to add the code below in along with the answer provided below:

//create the Activity
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//get a reference to the button element listed in the XML layout
Button speakButton = (Button)findViewById(R.id.speak);
Button speakButton1 = (Button)findViewById(R.id.button);
Button speakButton2 = (Button)findViewById(R.id.button2);
//listen for clicks
speakButton.setOnClickListener(this);
speakButton1.setOnClickListener(this);
speakButton2.setOnClickListener(this);
//check for TTS data

}
//respond to button clicks
public void onClick(View v) {
//get the text entered
EditText enteredText = (EditText)findViewById(R.id.enter);
String words = enteredText.getText().toString();
speakWords(words);
}
//speak the user text
private void speakWords(String speech) {
//speak straight away
myTTS.speak(speech, TextToSpeech.QUEUE_FLUSH, null);
}
//act on result of TTS data check
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == MY_DATA_CHECK_CODE) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
//the user has the necessary data - create the TTS
myTTS = new TextToSpeech(this, this);
}
else {
//no data - install it now
Intent installTTSIntent = new Intent();
installTTSIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(installTTSIntent);
}
}
}
//setup TTS
public void onInit(int initStatus) {
//check for successful instantiation
if (initStatus == TextToSpeech.SUCCESS) {

}
else if (initStatus == TextToSpeech.ERROR) {

}
}

If you want to do above thing in android then following code will help you add those lines in your onCreate()method
new CountDownTimer(600000, 60000) {//CountDownTimer(edittext1.getText()+edittext2.getText()) also parse it to long
public void onTick(long millisUntilFinished) {
System.out.println("Your message on every minute");
//here you can have your logic to set text to edittext
}
public void onFinish() {
System.out.println("Your message after 10 minute");
}
}
.start();

In AsyncTask, stop making registerReceiver() freeze the app

Since I finally figured out that the registerReceiver() method is usually running on the UI-Thread, I now want to change that. I just need some advice of how I could do that.
How would I be able to change registerReceiver() to stop freezing my app?
My doInBackground() method from the AsyncTask, runs another method that is using the registerReceiver(mReceiver, filter) method (both variables are already defined). But I want to keep seeing my ProgressDialog instead of making the app freezing.
I read about using a Handler and a new Thread, but I need some help there.
Thanks in advance.
