You can autostart applications on boot by listening to the <code>android.intent.action.BOOT_COMPLETED</code> intent in a BroadcastReceiver and start your Activity from there. In the Activity you can register yourself as the new default homescreen[1] and handle the keys. 

I think there are some instances that you can't handle without modifying the framework (like longpress on Home to show currently active Applications) - I could also be mistaken though.

But for a prototype that could be sufficient.

Have fun tinkering!

<blockquote>
 Using the following methods you can build an application that will
 prevent "regular" users from playing with anything other than your
 application.
 
 The application is made of two modules. The main activity and a
 service. The service is configured to start at boot. When the service
 is started it checks if the activity is running or not. If it is not
 running it uses a timer to start the main activity.
 
 When the activity is paused it schedules the service to start in one
 second: Code:
</blockquote>

<pre><code>Sub Activity_Pause (UserClosed As Boolean)
 If kiosk Then StartServiceAt(KioskService, DateTime.Now + 1 * DateTime.TicksPerSecond, false) 
End Sub
</code></pre>

<blockquote>
 If the user presses on the home screen, the home screen will appear
 for several seconds. However your application will return to the front
 after a few seconds and the user will not be able to interact with any
 other applications or change the settings.
 
 The service is set to be a foreground service. This prevents Android
 from killing our service. Press on the Stop button to deactivate kiosk
 mode.

After searching for this for a while I've come up with a good solution. This only works on rooted devices though, but I guess if it's just for this one app then rooting it shouldn't be a problem.

<ul>
<li>Make your application the launcher by adding 

<pre><code>&lt;category android:name="android.intent.category.HOME" /&gt; 
</code></pre>

to your intent-filter</li>
<li>Make sure your app collapses the toolbar so you cannot reach the notification bar see <a href="https://stackoverflow.com/questions/7578804/how-to-disable-status-bar-notification-bar-on-android-programmatically">How to disable status bar / notification bar on android programmatically?</a> or <a href="http://blog.vogella.com/2011/02/28/android-hidding-the-status-and-title-bar/" rel="nofollow noreferrer">http://blog.vogella.com/2011/02/28/android-hidding-the-status-and-title-bar/</a></li>
<li>Then to stop any other programs from opening by mistake use an Accessibility Service to check for Window State Changed, compare the package to a white or black list and use ActivityManager.killBackgroundProcesses to kill if it shouldn't run.</li>
</ul>

In the new Android L Preview, Google has announced <a href="http://developer.android.com/preview/api-overview.html#Enterprise" rel="noreferrer">Task Locking</a>, which does exactly that. It does seem to need root however.

<blockquote>
 The L Developer Preview introduces a new task locking API that lets
 you temporarily restrict users from leaving your app or being
 interrupted by notifications. This could be used, for example, if you
 are developing an education app to support high stakes assessment
 requirements on Android. Once your app activates this mode, users will
 not be able to see notifications, access other apps, or return to the
 Home screen, until your app exits the mode.
 
 To prevent unauthorized usage, only authorized apps can activate task
 locking. Furthermore, task locking authorization must be granted by a
 specially-configured device owner app, through the
 <code>android.app.admin.DevicePolicyManager.setLockTaskComponents()</code> method.
 
 To set up a device owner, follow these steps:
 
 <ul>
 <li>Attach a device running an Android <code>userdebug</code> build to your development
 machine. </li>
 <li>Install your device owner app. </li>
 <li>Create a <code>device_owner.xml</code> file
 and save it to the <code>/data/system</code> directory on the device. </li>
 </ul>
</blockquote>

<pre><code>$ adb root
$ adb shell stop
$ rm /tmp/device_owner.xml
$ echo "&lt;?xml version='1.0' encoding='utf-8' standalone='yes' ?&gt;" &gt;&gt; /tmp/device_owner.xml
$ echo "&amp;device-owner package=\"&lt;your_device_owner_package&gt;\" name=\"*&lt;your_organization_name&gt;\" /&gt;" &gt;&gt; /tmp/device_owner.xml
$ adb push /tmp/device_owner.xml /data/system/device_owner.xml
$ adb reboot
</code></pre>

<blockquote>
 Before using the task locking API in your app, verify that your
 activity is authorized by calling
 DevicePolicyManager.isLockTaskPermitted().
 
 To activate task locking, call <code>android.app.Activity.startLockTask()</code>
 from your authorized activity.
 
 When task locking is active, the following behavior takes effect:
 
 <ul>
 <li>The status bar is blank, and user notifications and status information
 is hidden. </li>
 <li>The Home and Recent Apps buttons are hidden. </li>
 <li>Other apps may
 not launch new activities. </li>
 <li>The current app may start new activities,
 as long as doing so does not create new tasks. </li>
 <li>The user remains locked
 on your app until an authorized activity calls
 <code>Activity.stopLockTask()</code>.</li>
 </ul>
</blockquote>

<h2>Starting your app on boot</h2>

the BEST way to accomplish this is setting your app as the launcher

<pre><code>&lt;activity ...
 android:launchMode="singleInstance"
 android:windowActionBar="false"&gt;
 &lt;intent-filter&gt;
 &lt;action android:name="android.intent.action.MAIN" /&gt;
 &lt;category android:name="android.intent.category.HOME" /&gt;
 &lt;category android:name="android.intent.category.DEFAULT" /&gt;
 &lt;/intent-filter&gt;
&lt;/activity&gt;
</code></pre>

<h2>Locking your app</h2>

the most reliable way is to use a device with Lollipop or greater and make use of 

<pre><code>startLockTask
</code></pre>

first you must set your app as the device owner. NB your device must be unprovisioned: if you registered it you should do a factory reset and skip the account registration.

to be able to register your app you must first setup a DeviceAdminReceiver component:

<pre><code>package com.example.myapp;

public class MyDeviceAdminReceiver extends android.app.admin.DeviceAdminReceiver {
 @Override
 public void onEnabled(Context context, Intent intent) {
 Toast.makeText(context, "Device admin permission received", Toast.LENGTH_SHORT).show();
 }

 @Override
 public CharSequence onDisableRequested(Context context, Intent intent) {
 return "are you sure?";
 }

 @Override
 public void onDisabled(Context context, Intent intent) {
 Toast.makeText(context, "Device admin permission revoked", Toast.LENGTH_SHORT).show();
 }


 @Override
 public void onLockTaskModeExiting(Context context, Intent intent) {
 // here you must re-lock your app. make your activity know of this event and make it call startLockTask again!
 }
}
</code></pre>

once you have an unprovisioned device you can launch the following command from adb (no root required)

<pre><code>adb shell dpm set-device-owner com.example.myapp/.MyDeviceAdminReceiver
</code></pre>

to avoid android asking the user permissions to pin your app you must call
setLockTaskPackages

finally!

<pre><code>@Override
public void onResume(){
 super.onResume();
 DevicePolicyManager mDevicePolicyManager = (DevicePolicyManager) getSystemService(
 Context.DEVICE_POLICY_SERVICE);
 ComponentName mAdminComponentName = new ComponentName(getApplicationContext(), MyDeviceAdminReceiver.class);
 mDevicePolicyManager.setLockTaskPackages(mAdminComponentName, new String[]{getPackageName()});
 startLockTask();
}
@Override
public void finish(){
 stopLockTask();
 super.finish();
}
</code></pre>

Kiosk mode is nothing but locking a single or set of applications when you switch on an android device. This can be achieved by lock task mode. When the device runs in lock task mode, users typically can’t see notifications, access non-whitelisted apps, or return to the home screen.
The Device policy controller (DPC) can whitelist the app that can run when the system is in lock task mode. Since its a dedicated device for a specific purpose the person using the device can't leave lock task mode. The device which are Android 5.0 and higher can run in lock task mode.
<pre><code> • Whitelisting the applications
</code></pre>
First step is to whitelist the application by DPC.
DPC can whitelist the apps which can be used in lock task mode by calling
DevicePolicyManager.setLockTaskPackages()
<pre><code> ▪ Start lock task mode
</code></pre>
Once the whitelisting is done, DPC can call the below function to start the lock task.
ActivityOptions.setLockTaskEnabled()
You can find more details regarding the lock task mode here. <a href="https://developer.android.com/work/dpc/dedicated-devices/lock-task-mode" rel="nofollow noreferrer">https://developer.android.com/work/dpc/dedicated-devices/lock-task-mode</a>

I'm in the process of evaluating if and how a CF .NET enterprise application can be ported to run on Android devices. The application on Windows Mobile phones are run in kiosk mode where the application autostart in fullscreen-mode after booting and with the users unable to accidentally or willingly access any other parts of the phone. 

Is it possible on Android to have only one application autostart after booting and prevent users from accidentally (or willingly) access any other parts of the Android device?
