Change launcher in AOSP 11

I am building AOSP 11 for emulator x86_64 and trying to change Default Launcher with third party launcher.

I am using raspberry pi's launcher downloaded from here

when I manually compile this launcher and install using adb It works, like it gives prompt to choose launcher.

but I need to add in source code.

I have found that I need to override default launcher.

So I have modified raspberry pi's launcher's Android.bp file

  • add override section

  • add system_ext_specific: true.( because this is default launcher's path.)

     android_app {
 name: "RpLauncher",
 overrides: ["Home Launcher2 Launcher3 Launcher3QuickStep"],
 platform_apis: true,
 certificate: "platform",
 privileged: true,
 system_ext_specific: true,

 static_libs: [
   "androidx.legacy_legacy-support-v4",
   "androidx.recyclerview_recyclerview",
   "androidx.leanback_leanback",
   "kotlinx-coroutines-core",
 ],

 srcs: ["src/**/*.kt"],
 resource_dirs: ["res"],

    }

Added package name "RpLauncher" in build/target/product/handheld_system_ext.mk where default launcher(Launcher3QuickStep) package added.

PRODUCT_PACKAGES += \
Launcher3QuickStep \
Provision \
Settings \
StorageManager \
SystemUI \
WallpaperCropper \
RpLauncher \

After this when start the emulator only bootanimation appears and it never ends. Anyone have any idea about this ?

@Ashok Mutyala, thanks for your help.Now I can add launcher as privileged app Below are final changes

launcher's Android.bp

android_app {
name: "RpLauncher",
overrides: ["Home Launcher2 Launcher3 Launcher3QuickStep"],
platform_apis: true,
certificate: "platform",
privileged: true,
system_ext_specific: true,

static_libs: [
  "androidx.legacy_legacy-support-v4",
  "androidx.recyclerview_recyclerview",
  "androidx.leanback_leanback",
  "kotlinx-coroutines-core",
],

srcs: ["src/**/*.kt"],
resource_dirs: ["res"],
required: ["privapp_whitelist_com.arpi.rplauncher"],

}

create new file frameworks/base/data/etc/com.arpi.rplauncher.xml --> this is copy of frameworks/base/data/etc/com.android.launcher3.xml only change package name.

    system_ext_specific: true,
    sub_dir: "permissions",
