Since Android 11, SystemUI removed the recents task functionality, and the related work has been implemented by Launcher3's quickstep. This document records the configuration work for the entire Launcher3 project in Android Studio.
- Instead of changing the project's directory structure, we add additional configurations and dependencies to build Gradle environment support
- Only one change was made: commented out a deprecated code section to make the project runnable. All other content remains the same as the original repository

Import the code from the specific path directly into the project as a Module dependency. You can reference it directly through implementation project during build, or you can use gradle build to generate an aar and place it in the libs folder as a static package.
// AOSP/android-11/frameworks/libs/systemui/iconloaderlib
implementation project(':IconLoader')
Find the signing certificates in the AOSP/android-11/build/target/product/security path and use keytool-importkeypair to generate the keystore. Execute the following command:
./keytool-importkeypair -k testkey.keystore -p 123456 -pk8 testkey.pk8 -cert testkey.x509.pem -alias testkey
And add the following code to the gradle configuration:
signingConfigs {
testkey {
storeFile file("testkey.keystore")
storePassword '123456'
keyAlias 'testkey'
keyPassword '123456'
}
}
buildTypes {
debug {
minifyEnabled false
signingConfig signingConfigs.testkey
}
}
