RequiresPermission

@Target([AnnotationTarget.ANNOTATION_CLASS, AnnotationTarget.FUNCTION, AnnotationTarget.PROPERTY_GETTER, AnnotationTarget.PROPERTY_SETTER, AnnotationTarget.CONSTRUCTOR, AnnotationTarget.FIELD, AnnotationTarget.VALUE_PARAMETER]) class RequiresPermission
androidx.annotation.RequiresPermission

Denotes that the annotated element requires (or may require) one or more permissions.

Example of requiring a single permission: 

<code>
    @RequiresPermission(Manifest.permission.SET_WALLPAPER)
    public abstract void setWallpaper(Bitmap bitmap) throws IOException;
 
    @RequiresPermission(ACCESS_COARSE_LOCATION)
    public abstract Location getLastKnownLocation(String provider);
  </code>
Example of requiring at least one permission from a set: 
<code>
    @RequiresPermission(anyOf = {ACCESS_COARSE_LOCATION, ACCESS_FINE_LOCATION})
    public abstract Location getLastKnownLocation(String provider);
  </code>
Example of requiring multiple permissions: 
<code>
    @RequiresPermission(allOf = {ACCESS_COARSE_LOCATION, ACCESS_FINE_LOCATION})
    public abstract Location getLastKnownLocation(String provider);
  </code>
Example of requiring separate read and write permissions for a content provider: 
<code>
    @RequiresPermission.Read(@RequiresPermission(READ_HISTORY_BOOKMARKS))
    @RequiresPermission.Write(@RequiresPermission(WRITE_HISTORY_BOOKMARKS))
    public static final Uri BOOKMARKS_URI = Uri.parse("content://browser/bookmarks");
  </code>

When specified on a parameter, the annotation indicates that the method requires a permission which depends on the value of the parameter. For example, consider android.app.Activity.startActivity(android.content.Intent): 

<code>public void startActivity(@RequiresPermission Intent intent) { ... }
  </code>
Notice how there are no actual permission names listed in the annotation. The actual permissions required will depend on the particular intent passed in. For example, the code may look like this: 
<code>Intent intent = new Intent(Intent.ACTION_CALL);
    startActivity(intent);
  </code>
and the actual permission requirement for this particular intent is described on the Intent name itself: 
<code>
    @RequiresPermission(Manifest.permission.CALL_PHONE)
    public static final String ACTION_CALL = "android.intent.action.CALL";
  </code>

Properties

allOf

val allOf: Array<String>

Specifies a list of permission names that are all required.

If specified, anyOf() and value() must both be null.

anyOf

val anyOf: Array<String>

Specifies a list of permission names where at least one is required

If specified, allOf() and value() must both be null.

conditional

val conditional: Boolean

If true, the permission may not be required in all cases (e.g. it may only be enforced on certain platforms, or for certain call parameters, etc.

value

val value: String

The name of the permission that is required, if precisely one permission is required. If more than one permission is required, specify either allOf() or anyOf() instead.

If specified, anyOf() and allOf() must both be null.
