On previous versions of Android, if your app requested the system to load a shared library with
text relocations, the system displayed a warning but still allowed the library to be loaded.
Beginning in this release, the system rejects this library if your app's target SDK version is 23
or higher. To help you detect if a library failed to load, your app should log the
{@code dlopen(3)} failure, and include the problem description text that the {@code dlerror(3)}
call returns. To learn more about handling text relocations, see this
<a href="https://wiki.gentoo.org/wiki/Hardened/Textrels_Guide" class="external-link">guide</a>.</p>
