Android App crashing during start up, image resources related

Question

I have an android App which crash on Samsung S4, S5 and Note3 devices. The app has a LinearLayout in front, and renders 7 rows of a "category" option.

The common error is:

java.lang.OutOfMemoryError:

I'm using a ListView in the MainActivity, where each row is a single image asset. Like this:

<?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="fill_parent"
    android:layout_height="100dp"
    android:layout_margin="0dp"
    android:padding="0dp">

    <LinearLayout
        android:id="@+id/categoryViewContainer"
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:background="@drawable/category_logo_transport"
        android:orientation="vertical"
        tools:ignore="UselessParent">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="100dp"
            android:background="@drawable/gradient_bg"
            android:gravity="bottom"
            android:orientation="vertical"
            android:paddingBottom="10dp"
            android:paddingLeft="10dp"
            tools:ignore="RtlHardcoded,RtlSymmetry">

            <TextView
                android:id="@+id/categoryTitle"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:shadowColor="@color/Black"
                android:shadowDx="-5"
                android:shadowDy="-1"
                android:shadowRadius="10"
                android:text="@string/categorytitle"
                android:textColor="@color/White"
                android:textSize="28sp" />

            <TextView
                android:id="@+id/categoryDesc"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:maxLines="2"
                android:text="@string/categorydesc"
                android:textColor="@color/windowBackground"
                android:textSize="11sp"
                tools:ignore="SmallSp" />

        </LinearLayout>

    </LinearLayout>

</RelativeLayout>

I suppose that there could be a problem with the amount of memory used by so many images, but I've compressed each image to 35kB.

Try setting the image in an ImageView , not in a LinearLayout :

<?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="fill_parent"
    android:layout_height="100dp"
    android:layout_margin="0dp"
    android:padding="0dp">

    <ImageView
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:src="@drawable/category_logo_transport"/>

    <LinearLayout
        android:id="@+id/categoryViewContainer"
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:orientation="vertical"
        tools:ignore="UselessParent">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="100dp"
            android:background="@drawable/gradient_bg"
            android:gravity="bottom"
            android:orientation="vertical"
            android:paddingBottom="10dp"
            android:paddingLeft="10dp"
            tools:ignore="RtlHardcoded,RtlSymmetry">

            <TextView
                android:id="@+id/categoryTitle"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:shadowColor="@color/Black"
                android:shadowDx="-5"
                android:shadowDy="-1"
                android:shadowRadius="10"
                android:text="@string/categorytitle"
                android:textColor="@color/White"
                android:textSize="28sp" />

            <TextView
                android:id="@+id/categoryDesc"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:maxLines="2"
                android:text="@string/categorydesc"
                android:textColor="@color/windowBackground"
                android:textSize="11sp"
                tools:ignore="SmallSp" />

        </LinearLayout>

    </LinearLayout>

</RelativeLayout>
