25 /**
26  * Indicates that this policy API can be set by multiple admins.
27  *
28  * <p>Starting from Android U ({@link Build.VERSION_CODES#UPSIDE_DOWN_CAKE}), multiple management
29  * admins will be able to coexist on the same device (e.g. a financed device with an enterprise
30  * admin). This requires adding multi-admin support for all the policy-related APIs (mostly in
31  * {@link android.app.admin.DevicePolicyManager}). However, for Android U only a subset of
32  * APIs will be supported, those will be marked with {@literal @}SupportsCoexistence annotation.
33  * </p>
34  *
35  * Example:
36  * <pre>{@code
37  * {@literal @}SupportsCoexistence
38  * public boolean setPermissionGrantState({@literal @}NonNull ComponentName admin,
39  *          {@literal @}NonNull String packageName, {@literal @}NonNull String permission,
40  *          {@literal @}PermissionGrantState int grantState) {
41  *      throwIfParentInstance("setPermissionGrantState");
42  * }</pre>
