Example 2 with ContentProvider

use of android.content.ContentProvider in project android_frameworks_base by AOSPA.

the class ActivityThread method installProvider.

/**
     * Installs the provider.
     *
     * Providers that are local to the process or that come from the system server
     * may be installed permanently which is indicated by setting noReleaseNeeded to true.
     * Other remote providers are reference counted.  The initial reference count
     * for all reference counted providers is one.  Providers that are not reference
     * counted do not have a reference count (at all).
     *
     * This method detects when a provider has already been installed.  When this happens,
     * it increments the reference count of the existing provider (if appropriate)
     * and returns the existing provider.  This can happen due to concurrent
     * attempts to acquire the same provider.
