android - How to make app as a default system launcher? -

I have developed the Launcher application, the first time I installed it on the Android Android system, Amp; just one time. I've selected "Always" Now my app becomes the default launcher but when I update the app, the system re-pops the same selection dialog, I do not want to show that pop up. How to make the app as the default system launcher? To achieve this, do I need to create a system level app?

I have used the following permission to make the app a launcher

  & lt; Intent-filter & gt; & Lt; Action Android: name = "android.intent.action.MAIN" /> & Lt; Category android: name = "android.intent.category.HOME" /> & Lt; Category android: name = "android.intent.category.DEFAULT" /> & Lt; Category android: name = "android.intent.category.MONKEY" /> & Lt; / Intent-Filter & gt;
