So when I click on submit button,my app crashes automatically.I dont know what is the reason.

Before showing dialog
if(dialog != null && dialog.isShowing()) {
dialog.dismiss();//or cancel()
}
Try moving the dialog and its initialization from asyncthread

how to use data from child activity in MainActivity and use it as parameter in other methods

I want to send data from EditText in child activity to parent activity (MainActivity) and use it as a string parameter (URL) in other methods
Already I am able to send this using intent and extras, also I added textview in method to see if it works, but finally, this textview will be deleted, but I can't use it in other methods
public class MainActivity extends AppCompatActivity implements OnDataSendToActivity {
ImageView bg_state;
Button btn_rl;
TextView txt_network;
String url;
String my_url;
TextView tv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
bg_state = findViewById(R.id.bg_status);
txt_network = findViewById(R.id.txt_network);
Toolbar toolbar= findViewById(R.id.toolbar);
setSupportActionBar(toolbar);
tv=findViewById(R.id.tV);
final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
if(isNetworkAvailable()){
bg_state.setImageResource(R.drawable.background);
txt_network.setText("");
}else{
bg_state.setImageResource(R.drawable.background_on);
txt_network.setText("Cound not connect to the server");
}
updateStatus();
handler.postDelayed(this, 2000);
}
}, 5000); //the time is in miliseconds
btn_rl = findViewById(R.id.sw_1);
btn_rl.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
String url_rl = my_url+"room_light";
SelectTask task = new SelectTask(url_rl);
task.execute();
updateStatus();
}
});
String url_rl = url+"bed_light";
SelectTask task = new SelectTask(url_rl);
task.execute();
updateStatus();

}
What I need is that if I write in Configuration class for example 192.168.xx.xx In mainactivity my_url will be my_url="https://192.168/ and it will be able to use in other methods as a parameter (for example in btn_rl.setOnClickListener).

Music stops on moving to another activity, while using background service to play music

I'm developing a game, I have used services to play music on all activities.
I want to stop the music when we hit the home key, it shouldn't stop playing music when moving from one activity to another.
public class backService extends Service {
private MediaPlayer mp;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
return START_STICKY;
}
#Override
public void onDestroy() {
super.onDestroy();
mp.stop();
mp.release();
}
#Override
public void onCreate() {
super.onCreate();
mp = MediaPlayer.create(this, R.raw.all);
mp.setLooping(true);
mp.start();
}
#Nullable
#Override
public IBinder onBind(Intent intent) {
return null;
}
}
and my main activity file
public class Home extends AppCompatActivity {
private AdView mAdView;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
hide();
setContentView(R.layout.activity_home);
Intent i = new Intent(this, backService.class);
adv();
}
#Override
protected void onResume(){
super.onResume();
Intent i = new Intent(this, backService.class);
startService(i);
}
#Override
protected void onStop() {
super.onStop();
Intent i = new Intent(this, backService.class);
stopService(i);
}
#Override
protected void onDestroy(){
super.onDestroy();
Intent i = new Intent(this, backService.class);
stopService(i);
}
}
How can I stop the music when I hit the home key and keep playing the music when we switch between other activities
TIA

Please remove the stopService(i) inside onStop() method in Activity coz whenever you are going one Activity to Another Activity then onStop() method will be called, that's why your service is killing.
If you want to pause or stop music while press home button then implements ComponentCallbacks2 interface to Activity like this
#Override
public void onTrimMemory(final int level) {
if (level == ComponentCallbacks2.TRIM_MEMORY_UI_HIDDEN) {
if(mService != null){
mService.pauseMusic();
}
}
}

Try to stop the service in
#Override
public void onPause()
{
super.onPause();
// Check if app is in foreground
if(!isAppOnForeground(context))
{
stop music here
}
}
below is the method to check if the app is in foreground or not . just replace your package here "your package name here";
public static boolean isAppOnForeground(Context context)
{
ActivityManager activityManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
List<ActivityManager.RunningAppProcessInfo> appProcesses = activityManager.getRunningAppProcesses();
if (appProcesses == null) {
return false;
}
final String packageName = "your package name here";
for (ActivityManager.RunningAppProcessInfo appProcess : appProcesses) {
if (appProcess.importance == ActivityManager.RunningAppProcessInfo.IMPORTANCE_FOREGROUND && appProcess.processName.equals(packageName)) {
return true;
}
}
return false;
}

How to pass values from one activity to another class

I need to pass a value either String to another class
From my activity, to a class that uses services
I have tried with an interface but it can not, you can only attach a fragment, and I can not do it with an attempt since it is a class that runs in the background
How could I do it?

saving activity state in media Player

I am an absolute beginner working on my first android app. I am working on an audio stream app and i implemented the mediaPlayer inside a service. There is a play-pause button that toggles if bound or not. The issue i have is that when isPlaying, and i change the screen orientation, though the service continues, the activity is recreated which makes the play button appear rather than the pause button. I know for me to retain the pause button, i need to override two methods - onSaveInstanceState and onRestoreInstanceState but i dont know the right logic to use in order to retain mainActivity's state.
Pls help me because the examples i saw didnt solve my problem.
This is my main activity
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//.......
if(savedInstanceState != null) {
boolean isPlaying = savedInstanceState.getBoolean("isPlaying");
if(!isPlaying){
imageButton2.setImageResource(R.drawable.stop);
} else {
imageButton2.setImageResource(R.drawable.play);
}
}
#Override
protected void onStart() {
// bind to the radio service
Intent intent = new Intent(this, RadioService.class);
startService(intent);
bindService(intent, mConnection, BIND_AUTO_CREATE);
super.onStart();
}
#Override
protected void onResume() {
super.onResume();
}
#Override
protected void onStop() {
// unbind the radio
// service
if (boundToRadioService) {
unbindService(mConnection);
boundToRadioService = false;
}
super.onStop();
}
#Override
protected void onDestroy() {
radioService.hideNotification();
if (boundToRadioService) {
unbindService(mConnection);
boundToRadioService = false;
}
super.onDestroy();
}
public void setupMediaPlayer(View view) {
if (boundToRadioService) {
boundToRadioService = false;
imageButton2.setImageResource(R.drawable.stop);
radioService.play();
} else {
boundToRadioService = true;
imageButton2.setImageResource(R.drawable.play);
radioService.pause();
#Override
protected void onSaveInstanceState(Bundle outState) {
outState.putBoolean("isPlaying", boundToRadioService);
super.onSaveInstanceState(outState);
}
}
This is my Service
// Binder given to clients
private final IBinder mBinder = new RadioBinder();
}
public void pause() {
audioManager.abandonAudioFocus(audioFocusChangeListener);
unregisterReceiver(audioBecomingNoisy);
mediaPlayer.pause();
}

return false;
}
#Override

return START_NOT_STICKY;
}
#Override
public void onPrepared(MediaPlayer mp) {
{
mp.start();
}
}
public class RadioBinder extends Binder {
RadioService getService() {
// Return this instance of RadioBinder so clients can call public methods
return RadioService.this;
}
}
#Nullable
#Override

return mBinder;
}

mediaPlayer.setAudioStreamType(AudioManager.STREAM_MUSIC);
new PlayerTask().execute(stream);
mediaPlayer.setOnPreparedListener(this);
mediaPlayer.setOnErrorListener(this);
mediaPlayer.reset();
showNotification();
Toast.makeText(this, "loading... please wait", Toast.LENGTH_LONG).show();
Log.i(TAG, "onCreate, Thread name " + Thread.currentThread().getName());
}
class PlayerTask extends AsyncTask<String, Void, Boolean> {
#Override
protected Boolean doInBackground(String... strings) {
try {
mediaPlayer.setDataSource(stream);
mediaPlayer.prepareAsync();
prepared = true;
} catch (IOException e) {
e.printStackTrace();
}
return prepared;
}
}

try this,
public class MainActivity extends AppCompatActivity {
private boolean boundToRadioService = false;
private ImageButton imageButton2;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

}
}
#Override

imageButton2.setImageResource(R.drawable.play);
radioService.pause();
} else {
boundToRadioService = true;
imageButton2.setImageResource(R.drawable.stop);
radioService.play();
}
}
}
and add android:src="#drawable/play" to the imagebutton in your xml file.
