Remarks
An ArrayList of String annotations describing content for #ACTION_CHOOSER.
If #EXTRA_CONTENT_ANNOTATIONS is present in an intent used to start a #ACTION_CHOOSER activity, the first three annotations will be used to rank apps.
Annotations should describe the major components or topics of the content. It is up to apps initiating #ACTION_CHOOSER to learn and add annotations. Annotations should be learned in advance, e.g., when creating or saving content, to avoid increasing latency to start #ACTION_CHOOSER. Names of customized annotations should not contain the colon character. Performance on customized annotations can suffer, if they are rarely used for #ACTION_CHOOSER in the past 14 days. Therefore, it is recommended to use the following annotations when applicable.
<ul> <li>"product" represents that the topic of the content is mainly about products, e.g., health & beauty, and office supplies.</li> <li>"emotion" represents that the topic of the content is mainly about emotions, e.g., happy, and sad.</li> <li>"person" represents that the topic of the content is mainly about persons, e.g., face, finger, standing, and walking.</li> <li>"child" represents that the topic of the content is mainly about children, e.g., child, and baby.</li> <li>"selfie" represents that the topic of the content is mainly about selfies.</li> <li>"crowd" represents that the topic of the content is mainly about crowds.</li> <li>"party" represents that the topic of the content is mainly about parties.</li> <li>"animal" represent that the topic of the content is mainly about animals.</li> <li>"plant" represents that the topic of the content is mainly about plants, e.g., flowers.</li> <li>"vacation" represents that the topic of the content is mainly about vacations.</li> <li>"fashion" represents that the topic of the content is mainly about fashion, e.g. sunglasses, jewelry, handbags and clothing.</li> <li>"material" represents that the topic of the content is mainly about materials, e.g., paper, and silk.</li> <li>"vehicle" represents that the topic of the content is mainly about vehicles, like cars, and boats.</li> <li>"document" represents that the topic of the content is mainly about documents, e.g. posters.</li> <li>"design" represents that the topic of the content is mainly about design, e.g. arts and designs of houses.</li> <li>"holiday" represents that the topic of the content is mainly about holidays, e.g., Christmas and Thanksgiving.</li> </ul>
