Closing application undoes last action

I have an alarm clock application, and I've just added code to exit the program when using the Back button from the main activity. However, when I do so, the last action the user took is undone. For example, if the user creates three alarms, then presses the back button, only two alarms will show up.
This is the Back button code, from Main Activity:
#Override
public void onBackPressed() {
moveTaskToBack(true);
android.os.Process.killProcess(android.os.Process.myPid());
System.exit(1);
}
And just in case, here's all the code from both activities I'm testing:
MainActivity.java (The only activity that has this Back button functionality, deliberately)
public class MainActivity extends AppCompatActivity {
ListView alarmListView;
ArrayList<Alarm> alarmList = new ArrayList<Alarm>();
AlarmAdapter alarmAdapter;
String filename = "alarmList";
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
alarmListView = findViewById(R.id.alarmListView);

For people from the future:
I ended up solving this by using the following:
#Override
public void onBackPressed() {
this.finishAffinity();

Adding Yandex Translator to Fragment leads to "App Crashes"

I'm Using Yandex Translator in my app, it works great if i'm using Activity, But when i add it to fragment , the app crashes before the launch.
Also no errors shown in the code , like everything is good, what could be the problem :
I looked for similar answers here, but i got nothing, no one had this issue before using fragments.
And here is the code for fragment :

Call setupInteraction() from onViewCreated(), not from onCreateView(). You are trying to use getView(), which will not work until onCreateView() returns.

Trouble expanding image in samsung s8

As screen height of samsung s8 is quite large.My images in LoginUI(attached) were looking small.I calculated phone's height in dp programmatically.
DisplayMetrics displayMetrics = getResources().getDisplayMetrics();
float dpHeight = displayMetrics.heightPixels / displayMetrics.density;
Log.d("checkheightdp",dpHeight+"");
It gave me dpheight 692.So,I create a separate layout-h692dp and put my layout with increased image height.For some reason,It is still picking the default layout and hence image not expanding.

Finally I got my answer,why creating a separate height layout was not working.
Though screen height of samsung s8 is 692 dp,but 25dp is not available as It is used by system UI.
Apparently it was stated in developer.android.com.
The Android system might use some of the screen for system UI (such as the system bar at the bottom of the screen or the status bar at the top), so some of the screen might not be available for your layout.
Therefore,subtracting 25 dp from 692 gives 667dp.Creating layout-h667dp worked.
I went to this post.

Try to tag the data model/ data source with your list view view.setTag(dataModel) in getView method of your adapter class.

Why not try RecyclerView instead of ListView and use Fresco Image Library?

Text To Speech speak() failure: not bound to the TTS engine in Android Studio

I'm getting an error when trying to use Text To Speech.
I have a Button and when I click it I'm getting an error in my logcat saying
E/TexttoSpeech: speak failed: not bound to TTS Engine.
Here's my cityinfo.class
public class CityInfo extends Activity implements View.OnClickListener{
SharedPreferences.Editor editor;
TextView cityname1, cityarea,citypopulation,cityregion,cityprovince,cityinfo1;

ViewFlipper viewFlipper;
TextToSpeech tts;

Try this,
This is useful to check whether a TTS engine is not available
Intent TTSIntent = new Intent();
TTSIntent.setAction(TextToSpeech.Engine.ACTION_CHECK_TTS_DATA);
startActivityForResult(TTSIntent, 2);
This is the code when onActivityResult, before running tts.speak ()
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == 2) {
if (resultCode == TextToSpeech.Engine.CHECK_VOICE_DATA_PASS) {
try{
TTS = new TextToSpeech(getApplicationContext(), this);
TTS.setOnUtteranceProgressListener(uPL);
} catch(Throwable throwable){
Log.e("Throwable", throwable.getMessage());
}
} else {
Intent m_installTTSIntent = new Intent();
m_installTTSIntent.setAction(TextToSpeech.Engine.ACTION_INSTALL_TTS_DATA);
startActivity(m_installTTSIntent);
}
}
}
