I am new android user and using Android Studio 1.3. I want to create simple splash screen, for that,i create different drawable folders where i store splash screen background images. I copy all ic\_launcher from respective mipmap folders and paste them in respective drawable folders. and change icon path in manifest also.as,

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

```

to,

```
 <application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >

```

but this is giving me error that,

```
Error:(14, 24) No resource found that matches the given name (at 'icon' with value '@mipmap/ic_launcher').

```

My question is,

1. Does we always need to store app icons in mipmap folders only? why?
2. When to use mipmap and drawable?
