How to modify application settings in a custom Android ROM?

Question

here's my problem :

I've already done some research with Google, Stack Overflow and XDA Developers forums but I didn't even find a related question.

I'm trying to customize this CyanogenMod ROM so the "Unknown sources" checkbox (in Settings > Applications) is checked by default after the installation of the ROM using ClockWorkMod, but I can't seem to find where to do it.

I searched into the following APK files using apktool :

• /system/framework/framework-res.apk
• /system/app/Settings.apk
• /system/app/SettingsProvider.apk
• /system/app/ApplicationsProvider.apk
• /system/app/PackageInstaller.apk
• /system/app/CertInstaller.apk

but I didn't find anything.

Any ideas ?

Solution

Ok, turns out I didn't search hard enough.

For those who are interested, the file to edit is located into SettingsProvider.apk.
You have to decompile it (with apktool) and edit the file SettingsProvider/res/values/bools.xml, replacing this line :

<bool name="def_install_non_market_apps">false</bool>

by this one :

<bool name="def_install_non_market_apps">true</bool>

And then, recompile, etc.

Hope this helps.

Also you may consider changing such values in CM sources, as described here stackoverflow.com/questions/16770639/…. In my case file overlay/frameworks/base/packages/SettingsProvider/res/values‌​/defaults.xml defines def_install_non_market_apps. Seems that app packages usually have config files in res/values/config.xml, which you can redefine in overlay for your device
