I recommend reading part 1 also, but just to summarize:
ro.HOME_APP_ADJ – BUSTED
This property is supposed to “keep the launcher in memory” under the assumption that it would somehow make it faster. Unfortunately, this is a leftover Gingerbread property that no longer functions in ICS.
// These values are set in system/rootdir/init.rc on startup.
HOME_APP_ADJ = getIntProp("ro.HOME_APP_ADJ", true);
static final int HOME_APP_ADJ = 6;
Google likely removed the ability to configure this value via a build.prop setting in ICS so that users could not set inappropriate values here.
As we have seen many times already, there are no “magic properties” that you can set that will simply make your phone [insert desired superlative]. That is not to say that all build.prop settings are pointless. Some can actually provide some useful functionality. The key is not to blindly throw a slew of “tweaks” into your build.prop, but to carefully consider each one and know what they do (if anything) before using them.
That’s it for part two. Let me know what build.prop settings you want to see in part three!
If you really want to keep your launcher in memory, you can use App Settings (xposed module); I know for a fact it works because I use it, or you can even do it yourself with a script such as:
echo "-17" > /proc/$PPID/oom_adj
To lower the oom value of the app you want to avoid getting killed off by android.
