Why does my GridView doesn't work?

Question

I was trying to practice to use GridView in Android Studio, I don't know why I keep getting this exception.

Here is the code of my main class.

public class MainActivity extends AppCompatActivity {
private GridView turtle;
private List<Map<String,Object>> datalist;
private int[] icon = {R.drawable.address_book,R.drawable.calendar,R.drawable.camera,R.drawable.clock,R.drawable.games_control,R.drawable.messenger,R.drawable.ringtone,R.drawable.settings,R.drawable.speech_balloon,R.drawable.weather,R.drawable.world,R.drawable.youtube};
private String  [] iconName = {"Contackt","Calendar","Camera","Clock","game","messager","ring","setting","voice","weather","browser","video"};
private SimpleAdapter adapter;


@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    turtle = (GridView) findViewById(R.id.turtle);
    datalist = new ArrayList<Map<String,Object>>();
    adapter = new SimpleAdapter(this,getdata(),R.layout.item,new String[]{"pic","txt"}, new int[]{R.id.pic,R.id.text});
    turtle.setAdapter(adapter);
}
private  List<Map<String,Object>> getdata(){
    for(int i = 0; i<icon.length;i++) {
        Map<String, Object> map = new HashMap<String, Object>();
        map.put("pic", icon[i]);
        map.put("text",iconName[i]);
        datalist.add(map);


    }


    return datalist;
}
}

Here is the code of my main XML file

<?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: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.example.jinyu.gridleview.MainActivity">

<GridView
    android:numColumns="3"
    android:verticalSpacing="10dp"
    android:horizontalSpacing="10dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/turtle"
    android:layout_centerVertical="true"
    android:layout_centerHorizontal="true" />
</RelativeLayout>

Here is the code of my item layout:

<?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"
android:background="#000000"
android:gravity="center"
>
<ImageView
    android:src="@drawable/ic_launcher"
    android:id="@+id/pic"
    android:layout_width="60dp"
    android:layout_height="60dp" />
<TextView
    android:layout_marginTop="5dp"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textColor="#ffffff"
    android:id="@+id/text"
    android:text="text"
    android:textSize="12dp"/>


</LinearLayout>

adapter = new SimpleAdapter(this,getdata(),R.layout.item,new String[]{"pic","txt"}, new int[]{R.id.pic,R.id.text}); this one? — Josiah Wu, Apr 14 '16 at 04:26
Issue is of Outofmemory not an adapter. have you mention large Heap in android manifiest. — Suhas Bachewar, Apr 14 '16 at 04:30
Do i have too? Cuz I was just follow a tutorial and it doesn't said that I need to. — Josiah Wu, Apr 14 '16 at 04:36
yes can you have to add android:largeHeap="true" in side Android Manifiest . — Suhas Bachewar, Apr 14 '16 at 04:38
But why we need to give largerHeap="true" for a small data. Something else is wrong. Are you running this app in Virtual device ? — vabhi vab, Apr 14 '16 at 04:39
Tell me what is your each image size mention in icon array list ? If each image of size more then it crashes as mention n Log. Your code works find and my end i have used image of 400 KB in icon arraylist — Suhas Bachewar, Apr 14 '16 at 04:51
the size of each image is 20kb. yeah, I did run this app in VD — Josiah Wu, Apr 14 '16 at 04:54
Yes You can run any where AVD or Virtual Device(Genymotion ) or try to run on real device. My virtual device Screen shot : http://tinypic.com/view.php?pic=25s0mfq&s=9#.Vw8i23V953U . — Suhas Bachewar, Apr 14 '16 at 04:57
You can try by editing configuration of your AVD. and increase size of memory there. or try in a real device. If you code is correct. then it will definitely work in hardware device. — vabhi vab, Apr 14 '16 at 05:07
I did increase the size of the memory of my AVD, but I still kept getting this exception — Josiah Wu, Apr 14 '16 at 05:21
@JosiahWu Have you tried on Real Device and made change in Android Manifest android:largeHeap="true" ? — Suhas Bachewar, Apr 14 '16 at 05:38
Did you increased Heap size as well ? if yes, then run it on hardware device. in some cases AVD gives problem. or you can try genymotion. — vabhi vab, Apr 14 '16 at 05:41
I did increase the heap size, I think I am going to try on my device. — Josiah Wu, Apr 14 '16 at 05:55
Yes, i faced same problem. but i usually use hardware device. so it worked on hardware device. if you are learning android now. Learn RecyclerView and give its Layout as StaggeredGridView. that also a good way to create gridView. — vabhi vab, Apr 14 '16 at 05:59
Thanks guys, I solve problem by running this app on my phone. — Josiah Wu, Apr 14 '16 at 22:42

You can't increase the heap size dynamically but you can request to use more by using.

android:largeHeap="true"

in the manifest.xml.

I did follow your instruction, but I kept getting java.lang.OutOfMemoryError: Failed to allocate a 9437196 byte allocation with 4194304 free bytes and 8MB until 00M – Josiah Wu Apr 14 '16 at 05:18
