Sets the value of the maximum number of non-self-issued intermediate
certificates that may exist in a certification path. A certificate
is self-issued if the DNs that appear in the subject and issuer
fields are identical and are not empty. Note that the last certificate
in a certification path is not an intermediate certificate, and is not
included in this limit. Usually the last certificate is an end entity
certificate, but it can be a CA certificate. A PKIX
{@code CertPathBuilder} instance must not build
paths longer than the length specified.
<p> A value of 0 implies that the path can only contain
a single certificate. A value of -1 implies that the
path length is unconstrained (i.e. there is no maximum).
The default maximum path length, if not specified, is 5.
Setting a value less than -1 will cause an exception to be thrown.
<p> If any of the CA certificates contain the
{@code BasicConstraintsExtension}, the value of the
{@code pathLenConstraint} field of the extension overrides
the maximum path length parameter whenever the result is a
certification path of smaller length.
@param maxPathLength the maximum number of non-self-issued intermediate
certificates that may exist in a certification path
@throws InvalidParameterException if {@code maxPathLength} is set

Use the given {@code button} to require scrolling. When scrolling is required, the button label
will change to {@code moreText}, and tapping the button will cause the page to scroll down.
<p>Note: Calling {@link View#setOnClickListener} on the button after this method will remove
its link to the require-scroll mechanism. If you need to do that, obtain the click listener
from {@link #createOnClickListener(OnClickListener)}.
<p>Note: The normal button label is taken from the button's text at the time of calling this
method. Calling {@link android.widget.TextView#setText} after calling this method causes
undefined behavior.
@param button The button to use for require scroll. The button's "normal" label is taken from
the text at the time of calling this method, and the click listener of it will be replaced.

The start and end are specified in the battery-stats monotonic time, which is the
adjusted elapsed time found in HistoryItem.time.

The aggregated stats are sent to the consumer. One aggregation pass may produce
multiple sets of aggregated stats if there was an incompatible change that occurred in the
middle of the recorded battery history.

Note: the AggregatedPowerStats object is reused, so the consumer should fully consume
the stats in the <code>accept</code> method and never cache it.

Carrier Action Agent(CAA) paired with

serves as an agent to dispatch carrier actions from carrier apps to different telephony modules,
{@link android.telephony.TelephonyManager#carrierActionSetRadioEnabled(int, boolean)
carrierActionSetRadioEnabled} for example.
CAA supports dynamic registration where different telephony modules could listen for a specific
carrier action event and implement their own handler. CCA will dispatch the event to all
interested parties and maintain the received action states internally for future inspection.
Each CarrierActionAgent is associated with a phone object.

deleted phone numbers easily, so check all updated contact's phone number and delete the
phone number. It will also delete the phone number that has been changed.
