Example 21 with ResourcesKey

use of android.content.res.ResourcesKey in project platform_frameworks_base by android.

the class ResourcesManager method createBaseActivityResources.

/**
     * Creates base resources for an Activity. Calls to
     * {@link #getResources(IBinder, String, String[], String[], String[], int, Configuration,
     * CompatibilityInfo, ClassLoader)} with the same activityToken will have their override
     * configurations merged with the one specified here.
     *
     * @param activityToken Represents an Activity.
     * @param resDir The base resource path. Can be null (only framework resources will be loaded).
     * @param splitResDirs An array of split resource paths. Can be null.
     * @param overlayDirs An array of overlay paths. Can be null.
     * @param libDirs An array of resource library paths. Can be null.
     * @param displayId The ID of the display for which to create the resources.
     * @param overrideConfig The configuration to apply on top of the base configuration. Can be
     *                       null. This provides the base override for this Activity.
     * @param compatInfo The compatibility settings to use. Cannot be null. A default to use is
     *                   {@link CompatibilityInfo#DEFAULT_COMPATIBILITY_INFO}.
     * @param classLoader The class loader to use when inflating Resources. If null, the
     *                    {@link ClassLoader#getSystemClassLoader()} is used.
     * @return a Resources object from which to access resources.
