You need to make your app into a service. Here is Androids take on creating services components:

<a href="http://developer.android.com/guide/components/services.html">http://developer.android.com/guide/components/services.html</a>

Found this as well on MobiWare:

When you want to track the usage of the mobile or gather some data without user knowledge,this might help you.

Step1: Create an application with No icon.
 Normally,an activity is declared as follows in manifest.

<pre><code> &lt;activity
 android:label="@string/app_name"
 android:name="org.security.tracker.Tracker-activity" &gt;
 &lt;intent-filter &gt;
 &lt;action android:name="android.intent.action.MAIN" /&gt;

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

Remove the Category TAG ,you wont get app icon anymore. 
Now,you don't need activity anymore. so remove this segment.
BUt you might think,how the app will run without any trigger or what is the starting point of the application.
This is the solution.

<pre><code>&lt;!-- Start the Service if applicable on boot --&gt;
 &lt;receiver android:name="org.security.tracker.ServiceStarter" &gt;
 &lt;intent-filter &gt;
 &lt;action android:name="android.intent.action.BOOT_COMPLETED" /&gt;
 &lt;/intent-filter&gt;
 &lt;/receiver&gt;
</code></pre>

This triggers your code that written in Receiver there by you can run service to implement your thoughts.

<pre><code> &lt;service android:name="org.security.tracker.serviceCode" /&gt;
</code></pre>

You need to add this permission,

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

Your code runs when the phone reboots only.

Step 2. Write your code

On Reboot,the recevier will fire ,there you can start your service.

<pre><code>class ServiceStarter extends BroadcastReceiver {

@Override
public void onReceive(Context _context, Intent _intent) {

 Intent i = new Intent("com.prac.test.MyPersistingService");
 i.setClass(_context, ServiceCode.class);
 _context.startService(i);
 }

 }
</code></pre>

 &lt;action android:name="android.intent.action.MAIN" /&gt;
 &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
 &lt;/intent-filter&gt;
</code></pre>

from the manifest file

blocks|key|404984|text|您可以从AndroidManifest.xml文件中删除<category+android:name="android.intent.category.LAUNCHER"/>。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|404985|但请记住添加<category+android:name="android.intent.category.LEANBACK_LAUNCHER"/>，以便Android+studio能够编译您的应用程序(但对启动程序隐藏)+:)+:D|404986|entityMap^0|S|1N|0|6|1W|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|M|8|@$9|N|A|O|B|C]]|D|@]|E|$]]|$1|H|3|-4|5|6|7|P|8|@]|D|@]|E|$]]]|I|$]]

You can remove the <code>&lt;category android:name="android.intent.category.LAUNCHER"/&gt;</code> from the AndroidManifest.xml file.

But remember to add <code>&lt;category android:name="android.intent.category.LEANBACK_LAUNCHER"/&gt;</code> so that Android studio will be able to compile your app (yet hidden from launcher) :) :D

The app can be hidden programmatically, Below is the code which will hide the app from the Launcher menu. this works fine android 10 as well
<pre><code>// App will be hidden when this method will be called from menu
private fun hideApp() {

 val packageManager =packageManager
 val name =ComponentName(this,MainActivity::class.java)
 packageManager.setComponentEnabledSetting(name,PackageManager.COMPONENT_ENABLED_STATE_DISABLED,PackageManager.DONT_KILL_APP)
 Log.d(&quot;TAG&quot;, &quot;hideApp: success&quot;)
}
</code></pre>

I'm writing a (legal) spy program. I want to make this program hidden on the launcher (so that no icon is shown). I tried to remove <code>&lt;category android:name="android.intent.category.LAUNCHER" /&gt;</code> line from <code>AndroidManifest.xml</code>, but then the user can't launch the application in first start mode (configuration). Who have any ideas ?

How can I do it?

Android hidden application

我在写一个(合法的)间谍程序。我想让这个程序隐藏在启动器上(这样就不会显示图标)。我试图从AndroidManifest.xml中删除<category android:name="android.intent.category.LAUNCHER" />行，但之后用户无法在首次启动模式(配置)下启动应用程序。谁有什么想...
