Hide app’s icon using below code:

PackageManager p = getPackageManager(); ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class); // activity which is first time open in manifiest file which is declare as //  p.setComponentEnabledSetting(componentName,PackageManager.COMPONENT_ENABLED_STATE_DISABLED, PackageManager.DONT_KILL_APP);

Here is how to bring back the app’s icon.

PackageManager p = getPackageManager(); ComponentName componentName = new ComponentName(this, com.apps.MainActivity.class); p.setComponentEnabledSetting(componentName, PackageManager.COMPONENT_ENABLED_STATE_ENABLED, PackageManager.DONT_KILL_APP); Tricky work: Your are going to hide you mainActivity once you hide it the activity will not be found it's destroy so you need to create same another activity like mainActivity2 and you need to store boolean value to sharerdprefrence that whether icon is hidden then you need to open mainActivity2 else MainActivity. Otherwise it will give ActivityNotFoundException or NullPointerException. For something much more over call function: Question: I am having one tricky thing to do. After hiding icon I would like to launch the app if user called on specific number like #007. I have implemented outgoing call receiver and matching on number I am trying to start my main activity but its giving me ActivityNotFoundException IMPORTANT: It's somehow tricky if you need to do something with main activity in your app when it's hidden.You will face an ActivityNotFoundException. To make it work, you should unhide icon before doing anything to your main activity and hide it again after you are finished. Steps: 1-call received here 2-unhide icon 3-launch main activity 4-do your things on main activity 5-hide icon again

Android program to implement hide and show app

Android program to implement hide and show app.It should consist of an image and one button titled ‘Hide/Show’. Use the button to toggle the value from hide to show and from show to hide.You should be able to show image by clicking the show button and hiding it by clicking the same button.

First of all you will need to add an image to your res/drawable folder. In order to achieve that you go to res then goto drawable folder and right click on it, goto new and you should find an option as image asset choose image or clipart, then click on next and then finish. After this, now to display an image in Android you need to use ImageView class in the XML file, and to refer to that image in the drawable folder you need to use the following syntax app:srcCompat=”@drawable/image_name”. Now going to the MainActivity.java file here the logic is simple, basically at the start only “hide” button is displayed as the image will be already present, once you click on hide button you will set the hide button to invisible as well as the image to invisible and the “show” button to visible. You can also do this via a switch case statement only addition will be you will be taking a boolean variable and also you will need only one button, both ways are show below.

Steps to create the application:-

• Open Android Studio and create a new Android application and name it as “HideShow” and company domain as codedost so your package will be automatically set.
• Open an Empty Activity and name it as MainActivity.
• Copy the content of res/layout/activity_main.xml file.
• Run the application to launch Android emulator or you can run it on your mobile also(which is way faster).

MainActivity.java

package codedost.hideshow; import android.support.v7.app.AppCompatActivity; import android.os.Bundle; import android.view.View; import android.widget.Button; import android.widget.ImageView; import android.widget.TextView; public class MainActivity extends AppCompatActivity < ImageView sampleImage; Button show,hide; // boolean flag=true; @Override protected void onCreate(Bundle savedInstanceState) < super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); sampleImage = (ImageView)findViewById(R.id.imageView); show = (Button)findViewById(R.id.button5); hide = (Button)findViewById(R.id.button4); /*A better code uncomment this and the boolean variable and comment those other two functions below this to use this*/ /* hide.setOnClickListener(new View.OnClickListener() < @Override public void onClick(View v) < switch (v.getId()) < case R.id.button4: if(flag==true) < sampleImage.setVisibility(View.INVISIBLE); hide.setText("Show"); flag=false; >else < sampleImage.setVisibility(View.VISIBLE); hide.setText("Hide"); flag=true; >> > >); */ hide.setOnClickListener(new View.OnClickListener() < @Override public void onClick(View v) < sampleImage.setVisibility(View.INVISIBLE); hide.setVisibility(View.INVISIBLE); show.setVisibility(View.VISIBLE); >>); show.setOnClickListener(new View.OnClickListener() < @Override public void onClick(View v) < sampleImage.setVisibility(View.VISIBLE); show.setVisibility(View.INVISIBLE); hide.setVisibility(View.VISIBLE); >>); > >

Hide application on android using DevicePolicyManager

To use methods provided by DevicePolicyManager class we must make the app device owner. I have used dpm command to make my app deviec owner. following are the steps for it

1. first factory reset device
2. install your app and activate it as admin.
3. from terminal run following command

dpm set-device-owner packageNameOfApp/DeviceAdminRcvrwithFullPackageName

you can find delailed discussion here

You can use «dpm set-device-owner» on any admin application without any need to factory reset your device.

And remembrer this adb command should be used for test purpose only. Additionally to that admin feature is no more supported by Google.

You should be either Device owner or Profile Owner to use any API in DevicePolicyManager

NB: seem that some Manufacture still support Admin feature in there ROM like Samsung even if they use new Android version

How to hide other apps in Android?

I don’t know how can I hide another apps

Fortunately, you cannot do that from an ordinary SDK app, for obvious security reasons. Ransomware authors would love the ability to do what you are proposing.

There are some hooks for doing what amounts to «hide another apps» in the device owner APIs IIRC, but they require the app be a device owner app, and that requires special work at the time the phone or tablet is first powered on after being purchased.

You may be able to accomplish what you want on a rooted device, and you certainly can do it with your own custom ROM. You could also create a home screen that «hides» apps by simply not showing them in its own launcher.
