MaruSettings

This project is in experiement state to study the difficulty to extract Maru modification to Settings to a single app.

EXTRA_SETTINGS

<intent-filter>
    <action android:name="com.android.settings.action.EXTRA_SETTINGS" />
</intent-filter>

<meta-data
    android:name="com.android.settings.FRAGMENT_CLASS"
    android:value="com.maru.settings.desktop.DesktopDashboardFragment" />

<meta-data
    android:name="com.android.settings.category"
    android:value="com.android.settings.category.ia.homepage" />

<meta-data
    android:name="com.android.settings.title"
    android:value="@string/desktop_dashboard_title" />

<meta-data
    android:name="com.android.settings.summary"
    android:value="@string/desktop_dashboard_summary" />

If we add intent-filter with action com.android.settings.action.EXTRA_SETTINGS for Activity, the Settings will add this Activity to its categories. And if we add meta-data with key com.android.settings.category and value com.android.settings.category.ia.homepage, the Settings will add Activity to homepage dashboard, by searching this category from added categories list.

And we add the meta-data with key com.android.settings.summary with specific value, it will shown to the homepage dashboard.

SettingsLib

We use SettingsLib as library to create setting view. This library needs some runtime permissions to query user information. So we add the shared uid android.uid.system to skip the system checking for critic operations. Maybe we should assign the permission to the app from config file to replace shared uid.

View

We copy SwitchBar and ToggleButton from the Settings, and use it to our app.

How to use

Create directory apps in vendor/maruos, and add a Android.mk with following content:

LOCAL_PATH := $(call my-dir)

include $(call all-makefiles-under, $(LOCAL_PATH))

Then use below command to clone project to vendor/maruos/apps:

git clone https://github.com/utzcoz/vendor_maruos_packages_apps_MaruSettings.git MaruSettings

The next thing we should do is to add MaruSettings to vendor/maruos/device-maru.mk PRODUCT_PACKAGES:

PRODUCT_PACKAGES += \
    MaruSettings

And last, we just need to build the system, and flash the images to the device. We can see another Desktop entry on Settings dashboard homepage.
