  • Difficulty Level : Hard
  • Last Updated : 26 Feb, 2021

In every android phone, we have feature to take screenshots of screens. In this article, we are going to explain how to take screenshots programmatically. A sample GIF is given below to get an idea about what we are going to do in this article. Note that we are going to implement this project using the Java language. 

Attention reader! Don’t stop learning now. Get hold of all the important Java Foundation and Collections concepts with the Fundamentals of Java and Java Collections Course at a student-friendly price and become industry ready. To complete your preparation from learning a language to DS Algo and many more,  please refer Complete Interview Preparation Course.

Step by Step Implementation

Step 1: Create a New Project

To create a new project in Android Studio please refer to How to Create/Start a New Project in Android Studio. Note that select Java as the programming language.



Step 2: Add permission to the AndroidManifest.xml file

Add the following permissions to the AndroidManifest.xml file

<uses-permission android:name=”android.permission.READ_EXTERNAL_STORAGE”/>

<uses-permission android:name=”android.permission.WRITE_EXTERNAL_STORAGE”/>

Step 3: Working with the activity_main.xml file

Navigate to the app > res > layout > activity_main.xml and add the below code to that file. Below is the code for the activity_main.xml file. 

XML




<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:orientation="vertical"
    tools:context=".MainActivity">
  
    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Click on button to take screenshot"
        android:textColor="#000"
        android:textSize="20dp"
        android:textStyle="bold" />
  
    <Button
        android:id="@+id/clickme"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="10dp"
        android:background="@color/colorPrimary"
        android:text="Click Me" />
  
</LinearLayout>

Step 4: Add an audio file to the Raw folder

Please refer to the Resource Raw Folder in Android Studio and add an audio file to the Raw folder. 

Step 5: Working with the MainActivity.java file

Go to the MainActivity.java file and refer to the following code. Below is the code for the MainActivity.java file. Comments are added inside the code to understand the code in more detail.

        try {

            String dirpath = Environment.getExternalStorageDirectory() + "";
            File file = new File(dirpath);
            if (!file.exists()) {
                boolean mkdir = file.mkdir();
            }
              
            // File name
            String path = dirpath + "/" + filename + "-" + format + ".jpeg";
            view.setDrawingCacheEnabled(true);
            Bitmap bitmap = Bitmap.createBitmap(view.getDrawingCache());
            view.setDrawingCacheEnabled(false);
            File imageurl = new File(path);
            FileOutputStream outputStream = new FileOutputStream(imageurl);
            bitmap.compress(Bitmap.CompressFormat.JPEG, 50, outputStream);
            outputStream.flush();
            outputStream.close();
            return imageurl;
  
        } catch (FileNotFoundException io) {
            io.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return null;
    }
  
    // verifying if storage permission is given or not
    public static void verifystoragepermissions(Activity activity) {
          
        int permissions = ActivityCompat.checkSelfPermission(activity, Manifest.permission.WRITE_EXTERNAL_STORAGE);
          
        // If storage permission is not given then request for External Storage Permission
        if (permissions != PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(activity, permissionstorage, REQUEST_EXTERNAL_STORAGe);
        }
    }
}
