Android Studio: java.lang.OutOfMemoryError [duplicate]

Question

I am trying to get my application to display different views when Image buttons are clicked. Its a fairly simple application, but I cant test to see if it works because I keep getting an Out of Memory Error. Here is the java class

Edit:

I decreased the size of the button images by 50% and I still get an out of memory error. Additionally I added android:largeHeap="true" to the android manifest. Below are the original files but with updates

Dashboard.java

    package com.pixel.deloitte.xprizeapplication;

import android.graphics.Color;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import android.view.Window;
import android.widget.TabHost;
import android.widget.TextView;

import java.io.IOException;

public class Dashboard extends AppCompatActivity {
    //private TabHost tabHost;
    //private int[] tabs = {R.drawable.dashboardnotclicked,R.drawable.teamreviewnotclicked,R.drawable.teambiosnotclicked,R.drawable.mentornotclicked,R.drawable.schedulenotclicked};
    public static class MyUncaughtExceptionHandler implements Thread.UncaughtExceptionHandler {
        @Override
        public void uncaughtException(Thread thread, Throwable ex) {
            if (ex.getClass().equals(OutOfMemoryError.class)) {
                try {
                    android.os.Debug.dumpHprofData("/sdcard/dump.hprof");
                } catch (IOException e) {
                    e.printStackTrace();
                }
                ex.printStackTrace();
            }

        }
    }

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //Thread.currentThread().setDefaultUncaughtExceptionHandler(new MyUncaughtExceptionHandler());
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_dashboard);
        findViewById(R.id.login).setVisibility(View.VISIBLE);
    }

    public void buttonClick(View v){
        switch(v.getId()){
            case R.id.loginButton:
                break;
            case R.id.dashboardbtn:
                break;
            case R.id.teamreviewbtn:
                break;
            case R.id.teambios:
                break;
            case R.id.mentorsbtn:
                break;
            case R.id.schedulebtn:
                break;
        }
    }

}

Here is the error I get, the error is thrown at setContentView(R.layout.activity_dashboard)

    </ScrollView>

</RelativeLayout>

and here is the manifest

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.pixel.deloitte.xprizeapplication">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="XPrize"
        android:supportsRtl="true"
        android:largeHeap="true"
        android:theme="@style/AppTheme">
        <activity android:name=".Dashboard">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Answer 1

Set largeHeap property as True in AndroidManifest.xml by,

android:largeHeap="true"

So you can modify the AndroidManifest.xml as,

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.pixel.deloitte.xprizeapplication">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="XPrize"
        android:supportsRtl="true"

        android:largeHeap="true"

        android:theme="@style/AppTheme">
        <activity android:name=".Dashboard">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Answer 2

Your images on the buttons are (way) to big, so that to display them more Memory is needed than available, simply create icons / smaller versions of the images and have those shown on the buttons
