Uninstall APKs programmatically

Android Mobile Development Apps/Applications

This example demonstrate about Uninstall APKs programmatically

Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.xml.

<?xml version = "1.0" encoding = "utf-8"?>
<LinearLayout xmlns:android = "http://schemas.android.com/apk/res/android"
   android:orientation = "vertical"
   android:layout_width = "match_parent"
   android:gravity = "center"
   android:layout_height = "match_parent">
   <TextView
      android:id = "@+id/text"
      android:layout_width = "fill_parent"
      android:gravity = "center"
      android:textSize = "30sp"
      android:layout_height = "wrap_content"
      android:text = "Click here" />
</LinearLayout>

In the above code, we have taken text view.

Step 3 − Add the following code to src/MainActivity.java

<?xml version = "1.0" encoding = "utf-8"?>
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;
public class MainActivity extends Activity {
   TextView text;
   @Override
   public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
      setContentView(R.layout.activity_main);
      text = findViewById(R.id.text);
      text.setOnClickListener(new View.OnClickListener() {
         @Override
         public void onClick(View v) {
            Intent intent = new Intent(Intent.ACTION_DELETE);
            intent.setData(Uri.parse("package:com.example.myapplication"));
            startActivity(intent);
         }
      });
   }
}

To run the app from android studio, open one of your project's activity files and click Run icon from the toolbar. Select your mobile device as an option and then check your mobile device which will display your default screen –
