Step 1: Create a new project OR Open your project

Step 2: Create a new "Layout Resource File" in res>layout and name it as "installed_app_list.xml"

Step 2: Code

installed_app_list.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"android:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="vertical"android:padding="3dp"><LinearLayoutandroid:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="horizontal"android:padding="5dp"><ImageViewandroid:id="@+id/app_icon"android:layout_width="48dp"android:layout_height="48dp"/><LinearLayoutandroid:layout_marginLeft="3dp"android:layout_width="match_parent"android:layout_height="wrap_content"android:orientation="vertical"android:layout_marginStart="3dp"><TextViewandroid:id="@+id/list_app_name"android:layout_width="match_parent"android:layout_height="wrap_content"android:textStyle="bold"android:textSize="16dp"android:text="App Name"/><TextViewandroid:id="@+id/app_package"android:text="App Package Name"android:layout_width="match_parent"android:layout_height="wrap_content" /></LinearLayout></LinearLayout></LinearLayout>

activity_main.xml

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"xmlns:app="http://schemas.android.com/apk/res-auto"xmlns:tools="http://schemas.android.com/tools"android:layout_width="match_parent"android:layout_height="match_parent"android:orientation="vertical"tools:context=".MainActivity"><TextViewandroid:id="@+id/countApps"android:text="Count: "android:padding="5dp"android:layout_width="match_parent"android:layout_height="wrap_content" /><ListViewandroid:id="@+id/system_app_list"android:layout_width="match_parent"android:layout_height="wrap_content" /></LinearLayout>
