我尝试运行应用后，我的应用崩溃了

Question

一旦我尝试在模拟器中或通过Android设备运行我的应用程序，该应用程序就会崩溃。

我只是尝试查看调试工具提供的错误消息以尝试找出任何错误，但是我真的不知道是什么引起了问题

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"

    xmlns:app="http://schemas.android.com/apk/res-auto">

    <TextView
        android:id="@+id/happy_birthday"
        android:text="@string/birthday"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="30sp"/>

    <TextView
        android:id="@+id/dear_ian"
        android:layout_width="291dp"
        android:layout_height="wrap_content"
        android:layout_below="@id/happy_birthday"
        android:layout_marginStart="-127dp"
        android:layout_marginTop="3dp"
        android:layout_toEndOf="@id/happy_birthday"
        android:text="@string/ian"
        android:textSize="30sp" />

    <ImageView
        android:src="@drawable/download"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        tools:ignore="ContentDescription"
        app:srcCompat="@drawable/download"/>

    <TextView
        android:id="@+id/from_dennis"
        android:text="@string/dennis"
        android:layout_height="wrap_content"
        android:layout_width="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentEnd="true"
        android:textSize="30sp"/>

该应用程序应运行，但是我收到以下错误消息
