<h2 id="dpm">Checking Device Policy Encryption Status</h2>
<p>Device administration apps can use
{@link android.app.admin.DevicePolicyManager#getStorageEncryptionStatus
DevicePolicyManager.getStorageEncryptionStatus()} to check the current
encryption status of the device. If your app is targeting an API level
lower than Android N,
{@link android.app.admin.DevicePolicyManager#getStorageEncryptionStatus
getStorageEncryptionStatus()} will return
{@link android.app.admin.DevicePolicyManager#ENCRYPTION_STATUS_ACTIVE
ENCRYPTION_STATUS_ACTIVE} if the device is either using full-disk encryption,
or file-based encryption with Direct Boot. In both of these cases, data is
always stored encrypted at rest. If your app is targeting an API level of
Android N or higher,
{@link android.app.admin.DevicePolicyManager#getStorageEncryptionStatus
getStorageEncryptionStatus()} will return
{@link android.app.admin.DevicePolicyManager#ENCRYPTION_STATUS_ACTIVE
ENCRYPTION_STATUS_ACTIVE} if the device is using full-disk encryption. It will
return
{@link android.app.admin.DevicePolicyManager#ENCRYPTION_STATUS_ACTIVE_PER_USER
ENCRYPTION_STATUS_ACTIVE_PER_USER} if the device is using file-based encryption
with Direct Boot.</p>
<p>If you build a device administration app
that targets Android N, make sure to check for both
{@link android.app.admin.DevicePolicyManager#ENCRYPTION_STATUS_ACTIVE
ENCRYPTION_STATUS_ACTIVE} and
{@link android.app.admin.DevicePolicyManager#ENCRYPTION_STATUS_ACTIVE_PER_USER
ENCRYPTION_STATUS_ACTIVE_PER_USER} to determine if the device is
encrypted.</p>
