App crashes as soon as I add 2 relative layouts in a linear layout - why?

Question

So, heres the point:

I'm training up and making my first steps in android development and after I narrowed down a few errors myself, I finally came across one that I cant find the solution for.

I want to create an app that displays two pictures that split the screen in half horizontally. So I create a LinearLayout with a vertical orientation and add two RelativeLayout's inside it. I compile it and the build apparently completes but as soon as the app tries to start up on my mobile (Samsung S5 Neo) it says it stopped working and I land up on my desktop again. >.< Also, before tips alike arise - yes I started a new project for testing purposes already and the same error occurs. Also, when I remove that lines of code, the app works just fine on my mobile. So, that's my code:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    tools:context="removedbecausenotyourbusiness:P">

    <RelativeLayout
        android:layout_height="0dp"
        android:layout_weight="1"
        android:layout_width="match_parent">

        <ImageView
            android:id="@+id/background2"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/background2"
            android:scaleType="centerCrop"/>
    </RelativeLayout>

    <RelativeLayout
            android:layout_height="0dp"
            android:layout_weight="1"
            android:layout_width="match_parent">

        <ImageView
            android:id="@+id/background1"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:src="@drawable/background1"
            android:scaleType="centerCrop"/>
    </RelativeLayout>

</LinearLayout>

Also, I'd like to get to know if I can somehow get a log from my mobile as to WHY the app stopped working. Where can I get this?

EDIT: I believe I found what you were asking me for.

Add stacktrace. There can be thousands of reasons why it crashed, the stacktrace tells us what the issue is — Zoe, Dec 17 '16 at 16:57
my one wild guess would be using the same name for `drawable` and `id` , try to change the name of ID — Pavneet_Singh, Dec 17 '16 at 16:59

Here is some things you can do to fix the OutOfMemoryError from your images:

Add these lines in your AndroidManifest file under the application at the top:

android:hardwareAccelerated="false"

android:largeHeap="true"

So the very top of of your AndroidManifest will look something like this with the two added lines:

    <application
        android:hardwareAccelerated="false"  //added
        android:largeHeap="true"             //added
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme">

If that doesn't fix it, then you will need to compress your image files. You can do that on a site like https://tinyjpg.com/. It is probably just an issue of your images being too large!

Also next time you run into a problem like this, you need to use that error that you received in your crash log / stacktrace and search for the solution. In your case, you could have found this: Android:java.lang.OutOfMemoryError: Failed to allocate a 23970828 byte allocation with 2097152 free bytes and 2MB until OOM

True.. I guess the proper way to do this would be with an image library like Picasso. — Nick Friskel, Dec 17 '16 at 23:48
That could be one solution. Another solution can be to shrink the image in size because loading a small ic-launcher does not crash the app. So the image is probably big. Not sure what Picasso does but it could be a solution that isn't a workaround — Zoe, Dec 18 '16 at 19:08
