Set icon for Android application

Question

How can I set an icon for my Android application?

Answer 1

Put your images in mipmap folder and set in manifest file... like as

 <application android:icon="@mipmap/icon" android:label="@string/app_name" >
 .... 
 </application>  

App Folder Directory :

Icon Size & Format :

Answer 2

Place your images in drawables folder under either of the three and set it like this.

Code

<application android:icon="@drawable/your_icon" >
.... 
</application>  

Answer 3

You can start by reading the documentation.

Here is a link:

How to change the launcher logo of an app in Android Studio?

Answer 4

A bit old, but for future use:

Open Android Studio -> app/src/main/res -> Right Click -> Image Asset

Answer 5

It's simple.

Now simply go to menu File → New → Image Asset. This will open a new dialogue and then make sure Launcher Icons is selected (Which it is by default) and then browse to the directory of your icon (it doesn't have to be in the project resources) and then once selected make sure other settings are to your liking and hit done.

Now all resolutions are saved into their respective folders, and you don't have to worry about copying it yourself or using tools, etc.

Don't forget "Shape - none" for a transparent background.

Answer 6

Define the icon for android application

<application android:icon="drawable resource">
.... 
</application>

If your app available across large range of devices

You should create separate icons for all generalized screen densities, including low-, medium-, high-, and extra-high-density screens. This ensures that your icons will display properly across the range of devices on which your application can be installed...

Size & Format

Launcher icons should be 32-bit PNGs with an alpha channel for transparency. The finished launcher icon dimensions corresponding to a given generalized screen density are shown in the table below.

Place icon in mipmap or drawable folder

android:icon="@drawable/icon_name" or android:icon="@mipmap/icon_name"

developer.android.com/guide says,

This attribute must be set as a reference to a drawable resource containing the image (for example "@drawable/icon").

about launcher icons android-developers.googleblog.com says,

It’s best practice to place your app icons in mipmap- folders (not the drawable- folders) because they are used at resolutions different from the device’s current density. For example, an xxxhdpi app icon can be used on the launcher for an xxhdpi device.

Dianne Hackborn from Google (Android Framework) says,

If you are building different versions of your app for different densities, you should know about the "mipmap" resource directory. This is exactly like "drawable" resources, except it does not participate in density stripping when creating the different apk targets.

For launcher icons, the AndroidManifest.xml file must reference the mipmap/ location

<application android:name="ApplicationTitle"
         android:label="@string/app_label"
         android:icon="@mipmap/ic_launcher" >

Little bit more quoting this

1. You want to load an image for your device density and you are going to use it "as is", without changing its actual size. In this case you should work with drawables and Android will give you the best fitting image.

2. You want to load an image for your device density, but this image is going to be scaled up or down. For instance this is needed when you want to show a bigger launcher icon, or you have an animation, which increases image's size. In such cases, to ensure best image quality, you should put your image into mipmap folder. What Android will do is, it will try to pick up the image from a higher density bucket instead of scaling it up. This will increase sharpness (quality) of the image.

Fore more you can read mipmap vs drawable folders
