Hello friends, I have a question for you. I have an android app which basically are two activities the main_activity and a details activity . The first has a recyclerView with elements and when I touch one I enter the activity details the issue is that when I enter the activity_detalles the consumption of my app is doubled and goes from 65 mb to 125mb , when leaving this activity, this memory consumption is maintained, which means that users with a low-end telephone have failures.
How can I release memory when leaving the activity details? for this, here I put my activity details.
public class DetailActivity extends AppCompatActivity {
public static final String EXTRA_POSITION = "position";
RatingBar ratingBar;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_detail);
// MobileAds.initialize(getApplicationContext(), getString(R.string.llavedeapp));
setSupportActionBar((Toolbar) findViewById(R.id.toolbar));
getSupportActionBar().setDisplayHomeAsUpEnabled(true);
getSupportActionBar().setDisplayShowTitleEnabled(false);
// Set Collapsing Toolbar layout to the screen
final CollapsingToolbarLayout collapsingToolbar =
(CollapsingToolbarLayout) findViewById(R.id.collapsing_toolbar);
// Set title of Detail page
// collapsingToolbar.setTitle(getString(R.string.item_title));
ratingBar = (RatingBar) findViewById(R.id.ratingBarId);
ratingBar.setOnRatingBarChangeListener(new RatingBar.OnRatingBarChangeListener() {
@Override
public void onRatingChanged(RatingBar ratingBar, float rating, boolean fromUser) {
Toast.makeText(getApplicationContext(), getString(R.string.calificado) + " " + ratingBar.getRating() + " " + getString(R.string.estrellas), Toast.LENGTH_SHORT).show();
}
});
int postion = getIntent().getIntExtra(EXTRA_POSITION, 0);
Resources resources = getResources();
String[] places = resources.getStringArray(R.array.nombre_coctel);
collapsingToolbar.setTitle(places[postion % places.length]);
String[] placeDetails = resources.getStringArray(R.array.coctel_ingredientes);
TextView placeDetail = (TextView) findViewById(R.id.place_detail);
placeDetail.setText(placeDetails[postion % placeDetails.length]);
String[] placeLocations = resources.getStringArray(R.array.coctel_preparacion);
TextView placeLocation = (TextView) findViewById(R.id.place_location);
placeLocation.setText(placeLocations[postion % placeLocations.length]);
String[] acercaDelCoctel = resources.getStringArray(R.array.coctel_descripcion);
TextView acercaCoctel = (TextView) findViewById(R.id.acerca_del_coctel);
acercaCoctel.setText(acercaDelCoctel[postion % acercaDelCoctel.length]);
final TypedArray placePictures = resources.obtainTypedArray(R.array.places_picture);
ImageView placePicutre = (ImageView) findViewById(R.id.image);
placePicutre.setImageDrawable(placePictures.getDrawable(postion % placePictures.length()));
TextView textHistoriaCoctel = (TextView) findViewById(R.id.TextHistoria);
String[] historiaDelCoctel = resources.getStringArray(R.array.historia_coctel);
TextView historiaCoctel = (TextView) findViewById(R.id.historia_coctel);
//Verifico que el cóctel tenga una historia en el el array de historia
//de lo contrario desaparezco las vistas de la pantalla
if ((historiaDelCoctel[postion]).isEmpty()) {
textHistoriaCoctel.setVisibility(View.GONE);
historiaCoctel.setVisibility(View.GONE);
} else {
textHistoriaCoctel.setVisibility(View.VISIBLE);
historiaCoctel.setVisibility(View.VISIBLE);
historiaCoctel.setText(historiaDelCoctel[postion % historiaDelCoctel.length]);
