howdy, Zuojun!

how can I help you?

Hello

I have a question: I want to launch an application when system boots

It is like a launcher

I know that I can do it by editing the framework level

and set my app as launcher in the manifest file, then delete the system own launcher

I want to know whether I can do it just in application level, replace the launcher by my own edtion

you can make yours be an option for the user

you cannot force the user to choose yours, nor can you remove the system's launcher

My assumption to do it is that I can edit the system. Because it will be an custom ROM

then your original plan is probably what you want: "set my app as launcher in the manifest file, then delete the system own launcher"

Can I finish it in application level? I do not want to edit the framework level.

I repeat: you can make yours be an option for the user, but you cannot force the user to choose yours, nor can you remove the system's launcher at the application level

OK. Thanks you.

Do you know any blog or something mentioned this kind of function? If there is some I will appreciate it

I do not know what you mean by "this kind of function"

if you mean "how to create a custom ROM", that is not my area of expertise, sorry

build an own launcher to replace the system edition

I do not have any resources on how to replace a system launcher, sorry

It is OK. Never mind

I just read your book. Its material is abundant.

Thanks for your work

you are very welcome

Besides the office hour, is there other way to ask questions to you?

I answer many questions on StackOverflow, though certainly not all of them

Yes. I found your blog on stackoverflow

OK, if I have question I will ask questions there and labeled "commonsware"

the 'commonsware' tag is for questions regarding the book or my open source projects

please do not use that tag for general Android development questions

yes, that is right

I have no more question today

Have a nice day

you too!
