Merge "Add more detail to javadocs for SimPhonebookContract"

 * The contract between the provider of contact records on the device's SIM cards and applications.

 * Contains definitions of the supported URIs and columns.

 *

 * <p>This content provider does not support any of the QUERY_ARG_SQL* bundle arguments. An

 * IllegalArgumentException will be thrown if these are included.

 * <h3>Permissions</h3>

 * <p>

 * Querying this provider requires {@link android.Manifest.permission#READ_CONTACTS} and writing

 * to this provider requires {@link android.Manifest.permission#WRITE_CONTACTS}

     * <h3 id="simrecords-data">Data</h3>

     * <p>

     * Data is stored in a specific elementary file on a specific SIM card and these are isolated

     * from each other. SIM cards are identified by their subscription ID. SIM cards may not support

     * all or even any of the elementary file types. A SIM will have constraints on

     * the values of the data that can be stored in each elementary file. The available SIMs,

     * their supported elementary file types and the constraints on the data can be discovered by

     * querying {@link ElementaryFiles#CONTENT_URI}. Each elementary file has a fixed capacity

     * for the number of records that may be stored. This can be determined from the value

     * of the {@link ElementaryFiles#MAX_RECORDS} column.

     * </p>

     * <p>

     * The {@link SimRecords#PHONE_NUMBER} column can only contain dialable characters and this

     * applies regardless of the SIM that is being used. See

     * {@link android.telephony.PhoneNumberUtils#isDialable(char)} for more details. Additionally

     * the phone number can contain at most {@link ElementaryFiles#PHONE_NUMBER_MAX_LENGTH}

     * characters. The {@link SimRecords#NAME} column can contain at most

     * {@link ElementaryFiles#NAME_MAX_LENGTH} bytes when it is encoded for storage on the SIM.

     * Encoding is done internally and so the name should be provided unencoded but the number of

     * bytes required to encode it will vary depending on the characters it contains. This length

     * can be determined by calling

     * {@link SimRecords#getEncodedNameLength(ContentResolver, String)}.

     * </p>

     * <h3>Operations </h3>

     * <dl>

     * <dd><b>Insert</b></dd>

     * <p>

     * Only {@link ElementaryFiles#EF_ADN} supports inserts. {@link SimRecords#PHONE_NUMBER}

     * is a required column. If the value provided for this column is missing, null, empty

     * or violates the requirements discussed in the <a href="#simrecords-data">Data</a>

     * section above an {@link IllegalArgumentException} will be thrown. The

     * {@link SimRecords#NAME} column may be omitted but if provided and it violates any of

     * the requirements discussed in the <a href="#simrecords-data">Data</a> section above

     * an {@link IllegalArgumentException} will be thrown.

     * </p>

     * <p>

     * If an insert is not possible because the elementary file is full then an

     * {@link IllegalStateException} will be thrown.

     * </p>

     * <dd><b>Update</b></dd>

     * <p>

     * Updates can only be performed for individual records on {@link ElementaryFiles#EF_ADN}.

     * A specific record is referenced via the Uri returned by

     * {@link SimRecords#getItemUri(int, int, int)}. Updates have the same constraints and

     * behavior for the {@link SimRecords#PHONE_NUMBER} and {@link SimRecords#NAME} as insert.

     * However, in the case of update the {@link SimRecords#PHONE_NUMBER} may be omitted as

     * the existing record will already have a valid value.

     * </p>

     * <dd><b>Delete</b></dd>

     * <p>

     * Delete may only be performed for individual records on {@link ElementaryFiles#EF_ADN}.

     * Deleting records will free up space for use by future inserts.

     * </p>

     * <dd><b>Query</b></dd>

     * <p>

     * All the records stored on a specific elementary file can be read via a Uri returned by

     * {@link SimRecords#getContentUri(int, int)}. This query always returns all records; there

     * is no support for filtering via a selection. An individual record can be queried via a Uri

     * returned by {@link SimRecords#getItemUri(int, int, int)}. Queries will throw an

     * {@link IllegalArgumentException} when the SIM with the subscription ID or the elementary file

     * type are invalid or unavailable.
