I am trying to implement paging in one activity but I keep running out of memory. The app runs till the 4th page but when it gets to the 5th it crashes. I've tried increasing the JVM heap size but the app still crashes at this one point where it runs out of memory to allocate.

This is my main file:

public class S1Intro extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_s1);

    MyPagerAdapter adapter = new MyPagerAdapter();
    ViewPager myPager = (ViewPager) findViewById(R.id.intro_panels);
    myPager.setAdapter(adapter);
    myPager.setCurrentItem(0);
}

Intent intent = new Intent(S1Intro.this,S2CharacterIntro.class);

public void nextScreen(View view){
    startActivity(intent);
}

This is the PageAdapter Class:

public class MyPagerAdapter extends PagerAdapter {

public int getCount() {
    return 5;
}

public Object instantiateItem(View collection, int position) {

    LayoutInflater inflater = (LayoutInflater) collection.getContext()
            .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    int resId = 0;
    switch (position) {
        case 0:
            resId = R.layout.s1a;
            break;
        case 1:
            resId = R.layout.s1b;
            break;
        case 2:
            resId = R.layout.s1c;
            break;
        case 3:
            resId = R.layout.s1d;
            break;
        case 4:
            resId = R.layout.s1e;
            break;
    }

    View view = inflater.inflate(resId, null);

    ((ViewPager) collection).addView(view, 0);

    return view;
}

@Override
public void destroyItem(View arg0, int arg1, Object arg2) {
    ((ViewPager) arg0).removeView((View) arg2);

}


@Override
public boolean isViewFromObject(View arg0, Object arg1) {
    return arg0 == ((View) arg1);

}

@Override
public Parcelable saveState() {
    return null;
}

}

This is the 1st page's xml file:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="match_parent"
android:layout_height="match_parent">
<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/a"/>
</LinearLayout>

All the other pages are just like this with different drawables. Except the 5th page, which looks like this:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/activity_screen2"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.miniproject32.writeup.S1Intro">
<ImageView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:src="@drawable/e"/>
<Button
    style="@style/buttonStyle"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/button_s1"
    android:text="@string/start"
    android:onClick="nextScreen"/>
</RelativeLayout>

This is the logcat:

java.lang.OutOfMemoryError: Failed to allocate a 38125292 byte allocation with 16777216 free bytes and 21MB until OOM

You are trying to allocate an image that weighs 38MB. It's too much.

Either you make the source image weigh less, or you have to downsample the image and then load it.

Try to load image using Glide or Picasso.

For Glide

into Project level build.gradle

dependencies {
    compile 'com.github.bumptech.glide:glide:3.5.2'
    compile 'com.android.support:support-v4:22.0.0'
}

while displaying image, 

Glide.with(context)
    .load("imageURL")
    .into(ivImg);

For Piccaso

dependencies {
    compile 'com.squareup.picasso:picasso:2.5.1'
}

while displaying image, 

Picasso.with(context)
    .load(imageURL)
    .into(ivImg);

You add this code android:largeHeap="true" in your manifest. Then, you can follow this step

  1. Go to Run -> Run Configurations
  2. Select project under maven build
  3. Select tab "JRE"
  4. Enter -Xmx1024m

Alternatively, you could do

  1. Go to Run -> Run Configurations
  2. Select tab "JRE"
  3. Enter -Xmx1024m

This should increase the memory heap for all the builds/projects. You can optimize it the way you want.

    This is like saying "you can fix your memory leak by increasing the amount of memory available". Sure, it works, but it promotes bad habits -- like not fixing memory leaks. In this case, the better thing to do is to _not allocate 38MB of memory in the first place_, not make it fail to cause problems until you've used up an entire gigabyte of memory. – Nic Apr 08 '17 at 00:15
