I have installed android open source project [AOSP 10] on my system and buid it and have run the emulator. It is showing the default google search bar on the top of the home screen. I want to remove that google search bar from there to make the home screen clear.
For removing that I have modified one file but I am not sure about which file I have to modified to remove that section.

I have modified an AndroidManifest.xml file which is at the directory "Android_AOSP/packages/apps/QuickSearchBox/AndroidManifest.xml", but that file have removed only the search icon but the background layout is still showing there.
Before the editing the following code the above search layout was same as the below google search layout.

I have just commented one section of the following code.

    </application>
</manifest>

I have changed the selected code only showing in the given image file.
And the changes happened after the build again which are showing in the emulator.
I want to fully remove the above search layout from the home screen but it is not happening.
Before editing the code it were looking same like the below search layout.
I have also tried by commenting all the code written inside the manifest tag section. But it not doing any changes except the showing changes. And if I delete this file then it will start giving the error.
I have tried by deleting the full ‘QuickSearchBox’ folder but after doing that no any changes happening in that section.

Check the code and layout changes in the given image. I only have commented the selected code and it showing changes in the emulator

    The way I used to remove the default home screen google search box was wrong.

    I have find the main solution of removing it without making much changes in the code. Follow the following steps to remove it.

    Step 1 : Go to the following directory inside your AOSP source directory

    Path : packages/apps/Launcher3/src/com/android/launcher3/config/

    Step 2 : Open the file named " BaseFlags.java "

    Step 3 : Find the following line of code and make change as following from " true " to " false "

    // Enable moving the QSB on the 0th screen of the workspace
    
    public static final boolean QSB_ON_FIRST_SCREEN = false;    // For show 'home screen search bar' make it true. // By default it was true
    

    Step 4 : Save the file.

    Step 5 : Make the source code and check the result. Google search bar get removed.


  2. thats not part of Android system, its Launcher app and design. I can’t find a dedicated doc page, but found some tutorial how to make own Launcher app. you can write own or find some 3rd-party with opened source and "friendly" licence, and modify it by removing this bar (if even present), then you may replace default launcher app in system files

    what you have done: you just modified app responsible for handling this widget actions, still in fact yet another app (launcher) is implementing this widget for own "desktop" design
