/**
 * Central system API to the overall input method framework (IMF) architecture,
 * which arbitrates interaction between applications and the current input method.
 * You can retrieve an instance of this interface with
 * {@link Context#getSystemService(String) Context.getSystemService()}.
 * 
 * <p>Topics covered here:
 * <ol>
 * <li><a href="#ArchitectureOverview">Architecture Overview</a>
 * </ol>
 * 
 * <a name="ArchitectureOverview"></a>
 * <h3>Architecture Overview</h3>
 * 
 * <p>There are three primary parties involved in the input method
 * framework (IMF) architecture:</p>
 * 
 * <ul>
 * <li> The <strong>input method manager</strong> as expressed by this class
 * is the central point of the system that manages interaction between all
 * other parts.  It is expressed as the client-side API here which exists
 * in each application context and communicates with a global system service
 * that manages the interaction across all processes.
 * <li> An <strong>input method (IME)</strong> implements a particular
 * interaction model allowing the user to generate text.  The system binds
 * to the current input method that is use, causing it to be created and run,
 * and tells it when to hide and show its UI.  Only one IME is running at a time.
 * <li> Multiple <strong>client applications</strong> arbitrate with the input
 * method manager for input focus and control over the state of the IME.  Only
 * one such client is ever active (working with the IME) at a time.
 * </ul>
 * 
 * 
 * <a name="Applications"></a>
 * <h3>Applications</h3>
 * 
 * <p>In most cases, applications that are using the standard
 * {@link android.widget.TextView} or its subclasses will have little they need
 * to do to work well with soft input methods.  The main things you need to
 * be aware of are:</p>
 * 
 * <ul>
 * <li> Properly set the {@link android.R.attr#inputType} in your editable
 * text views, so that the input method will have enough context to help the
 * user in entering text into them.
 * <li> Deal well with losing screen space when the input method is
 * displayed.  Ideally an application should handle its window being resized
 * smaller, but it can rely on the system performing panning of the window
 * if needed.  You should set the {@link android.R.attr#windowSoftInputMode}
 * attribute on your activity or the corresponding values on windows you
 * create to help the system determine whether to pan or resize (it will
 * try to determine this automatically but may get it wrong).
 * <li> You can also control the preferred soft input state (open, closed, etc)
 * for your window using the same {@link android.R.attr#windowSoftInputMode}
 * attribute.
 * </ul>
 * 
 * <p>More finer-grained control is available through the APIs here to directly
 * interact with the IMF and its IME -- either showing or hiding the input
 * area, letting the user pick an input method, etc.</p>
 * 
 * <p>For the rare people amongst us writing their own text editors, you
 * will need to implement {@link android.view.View#onCreateInputConnection}
 * to return a new instance of your own {@link InputConnection} interface
 * allowing the IME to interact with your editor.</p>
 * 
 * 
 * <a name="InputMethods"></a>
 * <h3>Input Methods</h3>
 * 
 * <p>An input method (IME) is implemented
 * as a {@link android.app.Service}, typically deriving from
 * {@link android.inputmethodservice.InputMethodService}.  It must provide
 * the core {@link InputMethod} interface, though this is normally handled by
 * {@link android.inputmethodservice.InputMethodService} and implementors will
 * only need to deal with the higher-level API there.</p>
 * 
 * See the {@link android.inputmethodservice.InputMethodService} class for
 * more information on implementing IMEs.
 * 
 * 
 * <a name="Security"></a>
 * <h3>Security</h3>
 * 
 * <p>There are a lot of security issues associated with input methods,
 * since they essentially have freedom to completely drive the UI and monitor
 * everything the user enters.  The Android input method framework also allows
 * arbitrary third party IMEs, so care must be taken to restrict their
 * selection and interactions.</p>
 * 
 * <p>Here are some key points about the security architecture behind the
 * IMF:</p>
 * 
 * <ul>
 * <li> <p>Only the system is allowed to directly access an IME's
 * {@link InputMethod} interface, via the
 * {@link android.Manifest.permission#BIND_INPUT_METHOD} permission.  This is
 * enforced in the system by not binding to an input method service that does
 * not require this permission, so the system can guarantee no other untrusted
 * clients are accessing the current input method outside of its control.</p>
 * 
 * <li> <p>There may be many client processes of the IMF, but only one may
 * be active at a time.  The inactive clients can not interact with key
 * parts of the IMF through the mechanisms described below.</p>
 * 
 * <li> <p>Clients of an input method are only given access to its
 * {@link InputMethodSession} interface.  One instance of this interface is
 * created for each client, and only calls from the session associated with
 * the active client will be processed by the current IME.  This is enforced
 * by {@link android.inputmethodservice.AbstractInputMethodService} for normal
 * IMEs, but must be explicitly handled by an IME that is customizing the
 * raw {@link InputMethodSession} implementation.</p>
 * 
 * <li> <p>Only the active client's {@link InputConnection} will accept
 * operations.  The IMF tells each client process whether it is active, and
 * the framework enforces that in inactive processes calls on to the current
 * InputConnection will be ignored.  This ensures that the current IME can
 * only deliver events and text edits to the UI that the user sees as
 * being in focus.</p>
 * 
 * <li> <p>An IME can never interact with an {@link InputConnection} while
 * the screen is off.  This is enforced by making all clients inactive while
 * the screen is off, and prevents bad IMEs from driving the UI when the user
 * can not be aware of its behavior.</p>
 * 
 * <li> <p>A client application can ask that the system let the user pick a
 * new IME, but can not programmatically switch to one itself.  This avoids
 * malicious applications from switching the user to their own IME, which
 * remains running when the user navigates away to another application.  An
 * IME, on the other hand, <em>is</em> allowed to programmatically switch
 * the system to another IME, since it already has full control of user
 * input.</p>
 * 
 * <li> <p>The user must explicitly enable a new IME in settings before
 * they can switch to it, to confirm with the system that they know about it
 * and want to make it available for use.</p>
 * </ul>
