Android 활동의 UI를로드하는 동안 Java 메모리 부족 오류

ImageButton, 2 개의 textView, textField 및 ImageView에서 매우 기본적인 활동을로드하려고했습니다.

    <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:clickable="false"
android:id="@+id/namescreenactivity">

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceLarge"
    android:text="Welcome to your Pet House"
    android:id="@+id/Welcome"
    android:textColor="#ff000000"
    android:textStyle="bold"
    android:layout_marginTop="94dp"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true" />

<EditText android:id="@+id/edit_message"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:hint="@string/edit_message"
    android:layout_marginTop="36dp"
    android:textColor="#ff000000"
    android:layout_below="@+id/Welcome"
    android:layout_alignEnd="@+id/Welcome" />

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textAppearance="?android:attr/textAppearanceMedium"
    android:text="Name your pet"
    android:id="@+id/NameLabel"
    android:layout_alignTop="@+id/edit_message"
    android:layout_alignStart="@+id/Welcome" />

<ImageView
    android:layout_width="100dp"
    android:layout_height="100dp"
    android:src="@drawable/sun"
    android:layout_alignBottom="@+id/Welcome"
    android:layout_alignParentEnd="true"
    android:layout_marginBottom="39dp"
    android:id="@+id/sun" />

<ImageButton
    android:layout_width="250dp"
    android:layout_height="250dp"
    android:id="@+id/imageButton"
    android:src="@drawable/camel"
    android:clickable="true"
    android:scaleType="fitXY"
    android:onClick="sendMessage"
    android:layout_alignParentBottom="true"
    android:layout_alignEnd="@+id/edit_message"
    android:layout_marginBottom="31dp" />

그리고 MainActivity.java의 OnCreate 함수에서 나는 단순히 setContentView (R.layout.activity_main); 그러나 내 응용 프로그램의 메모리 사용량 그래프는 약 44MB를 사용하고 있음을 보여줍니다 (앱에있는 모든 이미지의 총 크기는 1MB 미만이고 ImageButton에 사용 된 크기는 193KB 임).

이것이 내 앱이 충돌하고 메모리 부족 오류가 발생하는 이유라고 생각합니다.
