Merge "Update JavaDoc of EditorInfo#packageName." into mnc-dev

    /**

     * Name of the package that owns this editor.

     *

     * <p><strong>IME authors:</strong> In API level 22

     * {@link android.os.Build.VERSION_CODES#LOLLIPOP_MR1} and prior, do not trust this package

     * name. The system had not verified the consistency between the package name here and

     * application's uid. Consider to use {@link InputBinding#getUid()}, which is trustworthy.

     * Starting from Android MNC, the system verifies the consistency between this package name

     * and application uid before {@link EditorInfo} is passed to the input method as long as the

     * application sets a non-empty package name.</p>

     *

     * <p><strong>Editor authors:</strong> Starting from Android MNC, the application is no longer

     * able to establish input connections if the package name provided here is inconsistent with

     * application's uid. Note that the system does accept an empty string for an arbitrary

     * application uid.</p>
