You can use this:

<pre><code>Intent shortcutIntent = new Intent();
shortcutIntent.setClassName("packageName", "className");
//shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
//shortcutIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

Intent addIntent = new Intent();

//intent.putExtra("duplicate", false);
addIntent.setAction("com.android.launcher.action.INSTALL_SHORTCUT");
 context.sendBroadcast(addIntent);
</code></pre>

You have to use following permission in your AndroidManaifest.xml

<pre><code>&lt;uses-permission android:name="com.android.launcher.permission.INSTALL_SHORTCUT" /&gt;
</code></pre>

You can use the commented code according to your requirements.

Note that, perhaps, above API is not documented. But it works.

You could make a <code>setup</code> function that the user can use to do all potential actions. For example, make any necessary user-accessible folders(if they don't exist already), adding the shortcut to the home screen, and/or loading in initial data.

This is a function I'm actually writing now, so hopefully it turns out well. But yeah the point is to keep it out of the <code>onCreate()</code> so it doesn't get called every single time!

I use these methods to properly add or remove shortcuts. These methods are working pretty well and are the same as the Android System when the user manually add/remove a shortcut.

<pre><code>public static void addShortcut(Context context)
{
 Intent shortcut = new Intent("com.android.launcher.action.INSTALL_SHORTCUT");

 ApplicationInfo appInfo = context.getApplicationInfo();

 // Shortcut name
 shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, appInfo.name);
 shortcut.putExtra("duplicate", false); // Just create once

 // Setup activity shoud be shortcut object 
 ComponentName component = new ComponentName(appInfo.packageName, appInfo.className);
 shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent(Intent.ACTION_MAIN).setComponent(component));

 // Set shortcut icon
 ShortcutIconResource iconResource = Intent.ShortcutIconResource.fromContext(context, appInfo.icon);
 shortcut.putExtra(Intent.EXTRA_SHORTCUT_ICON_RESOURCE, iconResource);

 context.sendBroadcast(shortcut);
}

public static void deleteShortcut(Context context)
{
 Intent shortcut = new Intent("com.android.launcher.action.UNINSTALL_SHORTCUT");

 ApplicationInfo appInfo = context.getApplicationInfo();

 // Shortcut name
 shortcut.putExtra(Intent.EXTRA_SHORTCUT_NAME, appInfo.name);

 ComponentName comp = new ComponentName(appInfo.packageName, appInfo.className);
 shortcut.putExtra(Intent.EXTRA_SHORTCUT_INTENT, new Intent(Intent.ACTION_MAIN).setComponent(comp));

 context.sendBroadcast(shortcut);
}
</code></pre>

Permissions :

blocks|key|5835265|text|现在，Google+Play服务解决了这一问题。你不再需要添加任何代码来完成这项工作。现在，当你从Google+Play商店安装一个应用程序时，它会自动在主屏幕上创建徽标。它可以在Google+Play商店设置中处理。例外:如果您正在使用任何自定义roms或启动器，它不能与一些工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|5835266|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

This is now solved by the Google Play services. You don't have to add any codes to do it anymore. Now when you install an app from the Google Play Store it automatically creates the logo in the main screen. It can be handled in the Google Play store settings.
Exception : If you are using any custom roms or launchers, it does not work with some.

I had trouble with the above answers and that's because API 22 and maybe other APIs returns on getApplicationInfo().className in debug/emulation mode: 
"com.android.tools.fd.runtime.BootstrapApplication"

Most important thing is that I needed to set the entire path to the class for the class name. (see the changes)
 
For example, I had the following: 
packageName=com.example.user.myapp 
className=MainActivity 
In <a href="https://stackoverflow.com/a/7461755/5251010">Kailash answer</a> I needed to change this line:

<pre><code>shortcutIntent.setClassName("packageName", "className");
</code></pre>

to

<pre><code>shortcutIntent.setClassName("com.example.user.myapp", "com.example.user.myapp.MainActivity");
</code></pre>

 
In <a href="https://stackoverflow.com/a/12599712/5251010">ChristopheCVBs answer</a> I needed to change this line:

<pre><code>ComponentName comp = new ComponentName(appInfo.packageName, appInfo.className);
</code></pre>

to

<pre><code>ComponentName comp = new ComponentName(appInfo.packageName, appInfo.packageName+".MainActivity");

As you know, when app is nomally installed, icon is created at launcher menu screen.
What I want to do is create icon at user home screen during installation.
(without pressing icon for 5 seconds.)

I heard this from another source to just add

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

to AndroidManifest.xml file, but it didn't work.

Is there any other way to do it?

How can I place app icon on launcher home screen?
