Cannot replace default icon in android studio

问题

The image I am trying to replace the default icon with is 512x512px .png. To change the icon I go app/res [new; image asset;...]. It won't let me replace or create new icon set in the @drawable. My most recent thought are that I might not have unlocked some priveges but I am able edit contents of drawable by directly accessing it's location

Any ideas?

回答1:

The new version of android studio put default launcher icon(ic_launcher.png) in mipmap-xxx directories, so just copy and paste your new icon to these directores, and reference it as '@mipmap/you_icon', or in code 'R.mipmap.you_icon'. If you still want to use the keyword 'drawable', then create the drawable folders(drawable-xxx), and put your icon there, and reference it as '@drawable/you_icon', or in code 'R.drawable.you_icon'

回答2:

Place your icon in the drawable folder and then simply open your AndroidManifest.xml file and then set the icon you want like this ...

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

回答3:

As what you wrote

app/res [new; image asset;...]

You mean this one on the image right? What specific error does it shows? just make sure that your icon name is the same in the manifest android:icon="@mipmap/youricon"

回答4:

step 1. copy the icon image from mipmap to drawable folders and build your project.

step 2. Change the following code in AndroidManifest.xml

<application
    android:icon="@drawable/ic_launcher"
