Device keeps disconnecting from flutter, I don't know why, please help
In the Android simulator, this phenomenon is occurring continuously, and in ios, it works without any problem.

The Error Log shows
Throwing OutOfMemoryError
If you run your project on an emulator please clean it or uninstall your app.

Crash when switching between activities on Smartphone but works fine on an Emulator

So I'm using Android Studio on my PC and im testing the app in an emulator which works totally fine.
But when i try to use my smartphone connected to the pc, the app always crashes, when i try to switch the activity.
Everything else seems to work fine.
Anyone knows why this could be happening?
Thats the exception, that i get when the app chrashes:
[ 01-08 16:31:19.455 2922: 2922 E/ ]

android how to avoid this out of memory error

I have a lot of images say 500ish spread across 20 or so fragments, the images are all very small and it all loads fine, however i give the user a choice off 3 different kinds of images, and right now if the user changes images i get an OOM error, so i think its the way im handling the images i think i need to recycle the old ones first but im not confident on how to do that can anyone help?
here is how i populate my adapter ive just added two items to simplify things
private void prepareCardData(){
CardWriter cardWriter = new CardWriter(getResources().getDrawable(R.drawable.dog),"DOG","dog ");
cardMakerList.add(cardWriter);
cardWriter = new CardWriter(getResources().getDrawable(R.drawable.cat_ic),"CAT","cat ");
cardMakerList.add(cardWriter);
cardAdapter.notifyDataSetChanged();
}
and this is where i literally just wait for a shared preference change and call a method
private SharedPreferences.OnSharedPreferenceChangeListener listener = new
SharedPreferences.OnSharedPreferenceChangeListener() {
#Override
public void onSharedPreferenceChanged(SharedPreferences sharedPreferences, String key) {
if(key.equals("ICONS SELECTED")){
cardsChoice.setIcons(getActivity());
cardsToSet();
System.out.println("OneFrag pref listener");
}
}
};
public void cardsToSet(){
if (cardsChoice.bool_fragTwo == false) {
if (cardsChoice.group == 1) {
cardMakerList.clear();
prepareCardData();
cardsChoice.bool_fragTwo = true;
}
if (cardsChoice.group == 2) {
cardMakerList.clear();
prepareSimpleCardData();
cardsChoice.bool_fragTwo = true;
}
if (cardsChoice.group == 3) {
cardMakerList.clear();
preparePhotoCardData();
cardsChoice.bool_fragTwo = true;
}
}
}
so as mentioned i think i need to run this in its own thread and clear up and images that arent needed anymore but i think theres more to it then that can anyone help?
here is the stack trace

here is my ViewPagerAdapter
public class ViewPagerAdapter extends FragmentPagerAdapter {
final int PAGE_COUNT = 4;
// Tab Titles
private String tabtitles[] = new String[] {"Home","Shouts","Maps","Shouters"};
Context context;
public ViewPagerAdapter(FragmentManager fm) {
super(fm);
}
#Override
public int getCount() {
return PAGE_COUNT;
}
public Fragment getItem(int position) {
switch (position) {
// Open Fragment home.java
case 0:
FragmentHome fragmenthome = new FragmentHome();
return fragmenthome;
// Open Fragment shouters.java
case 1:
FragmentShouts fragmentshouts = new FragmentShouts();
return fragmentshouts;
case 2:
FragmentShouts_Maps fragmentshouts_maps = new FragmentShouts_Maps();
return fragmentshouts_maps;
case 3:
FragmentShouters fragmentshouters = new FragmentShouters();
return fragmentshouters;
}
return null;
}
#Override
public CharSequence getPageTitle(int position) {
return tabtitles[position];
}
here is my main activity class, i think i slightly agree with you, its a sliding tab strip which isnt natural for android, more commonly seen in ios devices and it worked smoothly before the implementation of the fourth tab but i noticed my toast would react slowly when user input was stored after a button was clicked
public class MainActivity extends FragmentActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// Get the view from activity_main.xml
setContentView(R.layout.activity_main);
// Locate the viewpager in activity_main.xml
ViewPager viewPager = (ViewPager) findViewById(R.id.pager);
// Set the ViewPagerAdapter into ViewPager
viewPager.setAdapter(new ViewPagerAdapter(getSupportFragmentManager()));
}
public void btnShout(View v) {
//allows for label to be changed to shouted once button is pressed
EditText txtInput = (EditText) findViewById(R.id.txtInput);
TextView lblShout = (TextView) findViewById(R.id.lblShout);
lblShout.setText("Shouted! ");
//allows for toast to be displayed once button is clicked
Toast toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.TOP | Gravity.LEFT, 0, 0);
toast.makeText(MainActivity.this, txtInput.getText() + " Has Been Shouted.", toast.LENGTH_SHORT).show();
}
}

You're doing too much work on the main thread.

If you are in need of executing long-running code, you should take a look at Android's threading tools (http://developer.android.com/guide/components/processes-and-threads.html and http://developer.android.com/training/multiple-threads/index.html). AsyncTask (http://developer.android.com/reference/android/os/AsyncTask.html) is your friend =)
