How to programmatically take a screenshot on Android?

How can I take a screenshot of a selected area of phone-screen not by any program but from code?

Here is Solutions:

We have many solutions to this problem, But we recommend you to use the first solution because it is tested & true solution that will 100% work for you.

Solution 1

Here is the code that allowed my screenshot to be stored on an SD card and used later for whatever your needs are:

First, you need to add a proper permission to save the file:

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

And this is the code (running in an Activity):

private void takeScreenshot() {
    Date now = new Date();
    android.text.format.DateFormat.format("yyyy-MM-dd_hh:mm:ss", now);

    try {
        // image naming and path  to include sd card  appending name you choose for file
        String mPath = Environment.getExternalStorageDirectory().toString() + "/" + now + ".jpg";

        // create bitmap screen capture
        View v1 = getWindow().getDecorView().getRootView();
        Bitmap bitmap = Bitmap.createBitmap(v1.getDrawingCache());

        File imageFile = new File(mPath);

        FileOutputStream outputStream = new FileOutputStream(imageFile);
        int quality = 100;
        bitmap.compress(Bitmap.CompressFormat.JPEG, quality, outputStream);

    } catch (Throwable e) {
        // Several error may come out with file handling or DOM

And this is how you can open the recently generated image:

private void openScreenshot(File imageFile) {
    Intent intent = new Intent();
    Uri uri = Uri.fromFile(imageFile);
    intent.setDataAndType(uri, "image/*");

If you want to use this on fragment view then use:

View v1 = getActivity().getWindow().getDecorView().getRootView();

instead of

View v1 = getWindow().getDecorView().getRootView();

on takeScreenshot() function


This solution doesn’t work if your dialog contains a surface view. For details please check the answer to the following question:

Android Take Screenshot of Surface View Shows Black Screen

Solution 2

Call this method, passing in the outer most ViewGroup that you want a screen shot of:

public Bitmap screenShot(View view) {
    Bitmap bitmap = Bitmap.createBitmap(view.getWidth(),
            view.getHeight(), Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    return bitmap;

Solution 3

Note: works only for rooted phone

Programmatically, you can run adb shell /system/bin/screencap -p /sdcard/img.png as below

Process sh = Runtime.getRuntime().exec("su", null,null);
OutputStream os = sh.getOutputStream();
os.write(("/system/bin/screencap -p " + "/sdcard/img.png").getBytes("ASCII"));

then read img.png as Bitmap and use as your wish.

Solution 4

No root permission or no big coding is required for this method.

On adb shell using below command you can take screen shot.

input keyevent 120

This command does not required any root permission so same you can perform from java code of android application also.

Process process;
process = Runtime.getRuntime().exec("input keyevent 120");

More about keyevent code in android see

Here we have used. KEYCODE_SYSRQ its value is 120 and used for System Request / Print Screen key.

As CJBS said, The output picture will be saved in /sdcard/Pictures/Screenshots

Solution 5

Mualig answer is very good, but I had the same problem Ewoks describes, I’m not getting the background. So sometimes is good enough and sometimes I get black text over black background (depending on the theme).

This solution is heavily based in Mualig code and the code I’ve found in Robotium. I’m discarding the use of drawing cache by calling directly to the draw method. Before that I’ll try to get the background drawable from current activity to draw it first.

// Some constants
final static String SCREENSHOTS_LOCATIONS = Environment.getExternalStorageDirectory().toString() + "/screenshots/";

// Get device dimmensions
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();

// Get root view
View view = mCurrentUrlMask.getRootView();

// Create the bitmap to use to draw the screenshot
final Bitmap bitmap = Bitmap.createBitmap(size.x, size.y, Bitmap.Config.ARGB_4444);
final Canvas canvas = new Canvas(bitmap);

// Get current theme to know which background to use
final Activity activity = getCurrentActivity();
final Theme theme = activity.getTheme();
final TypedArray ta = theme
    .obtainStyledAttributes(new int[] { android.R.attr.windowBackground });
final int res = ta.getResourceId(0, 0);
final Drawable background = activity.getResources().getDrawable(res);

// Draw background

// Draw views

// Save the screenshot to the file system
FileOutputStream fos = null;
try {
    final File sddir = new File(SCREENSHOTS_LOCATIONS);
    if (!sddir.exists()) {
    fos = new FileOutputStream(SCREENSHOTS_LOCATIONS
            + System.currentTimeMillis() + ".jpg");
    if (fos != null) {
        if (!bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fos)) {
            Log.d(LOGTAG, "Compress/Write failed");

} catch (FileNotFoundException e) {
    // TODO Auto-generated catch block
} catch (IOException e) {
    // TODO Auto-generated catch block

Solution 6

As a reference, one way to capture the screen (and not just your app activity) is to capture the framebuffer (device /dev/graphics/fb0). To do this you must either have root privileges or your app must be an app with signature permissions (“A permission that the system grants only if the requesting application is signed with the same certificate as the application that declared the permission”) – which is very unlikely unless you compiled your own ROM.

Each framebuffer capture, from a couple of devices I have tested, contained exactly one screenshot. People have reported it to contain more, I guess it depends on the frame/display size.

I tried to read the framebuffer continuously but it seems to return for a fixed amount of bytes read. In my case that is (3 410 432) bytes, which is enough to store a display frame of 854*480 RGBA (3 279 360 bytes). Yes, the frame, in binary, outputted from fb0 is RGBA in my device. This will most likely depend from device to device. This will be important for you to decode it =)

In my device /dev/graphics/fb0 permissions are so that only root and users from group graphics can read the fb0.

graphics is a restricted group so you will probably only access fb0 with a rooted phone using su command.

Android apps have the user id (uid) = app_## and group id (guid) = app_## .

adb shell has uid = shell and guid = shell, which has much more permissions than an app. You can actually check those permissions at /system/permissions/platform.xml

This means you will be able to read fb0 in the adb shell without root but you will not read it within the app without root.

Also, giving READ_FRAME_BUFFER and/or ACCESS_SURFACE_FLINGER permissions on AndroidManifest.xml will do nothing for a regular app because these will only work for ‘signature‘ apps.

Also check this closed thread for more details.

Solution 7

private void captureScreen() {
    View v = getWindow().getDecorView().getRootView();
    Bitmap bmp = Bitmap.createBitmap(v.getDrawingCache());
    try {
        FileOutputStream fos = new FileOutputStream(new File(Environment
                .getExternalStorageDirectory().toString(), "SCREEN"
                + System.currentTimeMillis() + ".png"));
        bmp.compress(CompressFormat.PNG, 100, fos);
    } catch (FileNotFoundException e) {
    } catch (IOException e) {

Add the permission in the manifest

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

For Supporting Marshmallow or above versions, please add the below code in the activity onCreate method

ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.WRITE_EXTERNAL_STORAGE},00);

Solution 8

My solution is:

public static Bitmap loadBitmapFromView(Context context, View v) {
    DisplayMetrics dm = context.getResources().getDisplayMetrics(); 
    v.measure(MeasureSpec.makeMeasureSpec(dm.widthPixels, MeasureSpec.EXACTLY),
            MeasureSpec.makeMeasureSpec(dm.heightPixels, MeasureSpec.EXACTLY));
    v.layout(0, 0, v.getMeasuredWidth(), v.getMeasuredHeight());
    Bitmap returnedBitmap = Bitmap.createBitmap(v.getMeasuredWidth(),
            v.getMeasuredHeight(), Bitmap.Config.ARGB_8888);
    Canvas c = new Canvas(returnedBitmap);

    return returnedBitmap;


public void takeScreen() {
    Bitmap bitmap = ImageUtils.loadBitmapFromView(this, view); //get Bitmap from the view
    String mPath = Environment.getExternalStorageDirectory() + File.separator + "screen_" + System.currentTimeMillis() + ".jpeg";
    File imageFile = new File(mPath);
    OutputStream fout = null;
    try {
        fout = new FileOutputStream(imageFile);
        bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fout);
    } catch (FileNotFoundException e) {
    } catch (IOException e) {
    } finally {

Images are saved in the external storage folder.

Solution 9

You can try the following library:
Android Screenshot Library (ASL) enables to programmatically capture screenshots from Android devices without requirement of having root access privileges. Instead, ASL utilizes a native service running in the background, started via the Android Debug Bridge (ADB) once per device boot.

Solution 10

Based on the answer of @JustinMorris above and @NiravDangi here we must take the background and foreground of a view and assemble them like this:

public static Bitmap takeScreenshot(View view, Bitmap.Config quality) {
    Bitmap bitmap = Bitmap.createBitmap(view.getWidth(), view.getHeight(), quality);
    Canvas canvas = new Canvas(bitmap);

    Drawable backgroundDrawable = view.getBackground();
    if (backgroundDrawable != null) {
    } else {

    return bitmap;

The quality parameter takes a constant of Bitmap.Config, typically either Bitmap.Config.RGB_565 or Bitmap.Config.ARGB_8888.

Solution 11

public class ScreenShotActivity extends Activity{

private RelativeLayout relativeLayout;
private Bitmap myBitmap;

protected void onCreate(Bundle savedInstanceState) {

    relativeLayout = (RelativeLayout)findViewById(; Runnable() {
        public void run() {

            //take screenshot
            myBitmap = captureScreen(relativeLayout);

            Toast.makeText(getApplicationContext(), "Screenshot captured..!", Toast.LENGTH_LONG).show();

            try {
                    //save image to SD card
                Toast.makeText(getApplicationContext(), "Screenshot saved..!", Toast.LENGTH_LONG).show();
            } catch (IOException e) {
                // TODO Auto-generated catch block



public static Bitmap captureScreen(View v) {

    Bitmap screenshot = null;
    try {

        if(v!=null) {

            screenshot = Bitmap.createBitmap(v.getMeasuredWidth(),v.getMeasuredHeight(), Config.ARGB_8888);
            Canvas canvas = new Canvas(screenshot);

    }catch (Exception e){
        Log.d("ScreenShotActivity", "Failed to capture screenshot because:" + e.getMessage());

    return screenshot;

public static void saveImage(Bitmap bitmap) throws IOException{

    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    bitmap.compress(Bitmap.CompressFormat.PNG, 40, bytes);
    File f = new File(Environment.getExternalStorageDirectory() + File.separator + "test.png");
    FileOutputStream fo = new FileOutputStream(f);



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

Solution 12

You can try to do something like this,

Getting a bitmap cache from a layout or a view by doing something like
First you gotta setDrawingCacheEnabled to a layout(a linearlayout or relativelayout, or a view)


Bitmap bm = layout.getDrawingCache()

Then you do whatever you want with the bitmap. Either turning it into an image file, or send the bitmap’s uri to somewhere else.

Solution 13

Short way is

FrameLayout layDraw = (FrameLayout) findViewById(; /*Your root view to be part of screenshot*/
Bitmap bmp = layDraw.getDrawingCache();

Solution 14

Most of the answers for this question use the the Canvas drawing method or drawing cache method. However, the View.setDrawingCache() method is deprecated in API 28. Currently the recommended API for making screenshots is the PixelCopy class available from API 24 (but the methods which accept Window parameter are available from API 26 == Android 8.0 Oreo). Here is a sample Kotlin code for retrieving a Bitmap:

fun saveScreenshot(view: View) {
    val window = (view.context as Activity).window
    if (window != null) {
        val bitmap = Bitmap.createBitmap(view.width, view.height, Bitmap.Config.ARGB_8888)
        val locationOfViewInWindow = IntArray(2)
        try {
            PixelCopy.request(window, Rect(locationOfViewInWindow[0], locationOfViewInWindow[1], locationOfViewInWindow[0] + view.width, locationOfViewInWindow[1] + view.height), bitmap, { copyResult ->
                if (copyResult == PixelCopy.SUCCESS) {
                // possible to handle other result codes ...
            }, Handler())
        } catch (e: IllegalArgumentException) {
            // PixelCopy may throw IllegalArgumentException, make sure to handle it

Solution 15

For those who want to capture a GLSurfaceView, the getDrawingCache or drawing to canvas method won’t work.

You have to read the content of the OpenGL framebuffer after the frame has been rendered. There is a good answer here

Solution 16

I have created a simple library that takes a screenshot from a View and either gives you a Bitmap object or saves it directly to any path you want

Solution 17

If you want to take screenshot from fragment than follow this:

  1. Override onCreateView():

            public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                     Bundle savedInstanceState) {
                // Inflate the layout for this fragment
                View view = inflater.inflate(R.layout.fragment_one, container, false);
                mView = view;
  2. Logic for taking screenshot:

     button.setOnClickListener(new View.OnClickListener() {
     public void onClick(View v) {
         View view =  mView.findViewById(;
          shareScreenShotM(view, (NestedScrollView) view); 
  3. method shareScreenShotM)():

    public void shareScreenShotM(View view, NestedScrollView scrollView){
         bm = takeScreenShot(view,scrollView);  //method to take screenshot
        File file = savePic(bm);  // method to save screenshot in phone.
  4. method takeScreenShot():

             public Bitmap takeScreenShot(View u, NestedScrollView z){
                int totalHeight = z.getChildAt(0).getHeight();
                int totalWidth = z.getChildAt(0).getWidth();
                Log.d("yoheight",""+ totalHeight);
                Log.d("yowidth",""+ totalWidth);
                u.layout(0, 0, totalWidth, totalHeight);
                Bitmap b = Bitmap.createBitmap(u.getDrawingCache());
                 return b;
  5. method savePic():

     public static File savePic(Bitmap bm){
            ByteArrayOutputStream bytes = new ByteArrayOutputStream();
            bm.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
             File sdCardDirectory =  new File(Environment.getExternalStorageDirectory() + "/Foldername");
           if (!sdCardDirectory.exists()) {
           //  File file = new File(dir, fileName);
          try {
             file = new File(sdCardDirectory, Calendar.getInstance()
                .getTimeInMillis() + ".jpg");
            new FileOutputStream(file).write(bytes.toByteArray());
            Log.d("Fabsolute", "File Saved::--->" + file.getAbsolutePath());
             Log.d("Sabsolute", "File Saved::--->" + sdCardDirectory.getAbsolutePath());
         } catch (IOException e) {
         return file;

For activity you can simply use View v1 = getWindow().getDecorView().getRootView(); instead of mView

Just extending taraloca’s answer. You must add followings lines to make it work. I have made the image name static. Please ensure you use taraloca’s timestamp variable incase you need dynamic image name.

    // Storage Permissions
private static final int REQUEST_EXTERNAL_STORAGE = 1;
private static String[] PERMISSIONS_STORAGE = {

private void verifyStoragePermissions() {
    // Check if we have write permission
    int permission = ActivityCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);

    if (permission != PackageManager.PERMISSION_GRANTED) {
        // We don't have permission so prompt the user
        ActivityCompat.requestPermissions(this, PERMISSIONS_STORAGE, REQUEST_EXTERNAL_STORAGE);

public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);

    if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {
        if (requestCode == REQUEST_EXTERNAL_STORAGE) {

And in the AndroidManifest.xml file following entries are must:

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

For Full Page Scrolling Screenshot

If you want to capture a full View screenshot (Which contains a scrollview or so) then have a check at this library

All you have to do is import the Gradel, and create an object of BigScreenshot

BigScreenshot longScreenshot = new BigScreenshot(this, x, y);

A callback will be received with the bitmap of the Screenshots taken while automatically scrolling through the screen view group and at the end assembled together.

@Override public void getScreenshot(Bitmap bitmap) {}

Which can be saved to the gallery or whatsoever usage is necessary their after

Solution 20

For system applications only!

Process process;
process = Runtime.getRuntime().exec("screencap -p " + outputPath);

Note: System applications don’t need to run “su” to execute this command.

Method 21

The parameter view is the root layout object.

public static Bitmap screenShot(View view) {
                    Bitmap bitmap = null;
                    if (view.getWidth() > 0 && view.getHeight() > 0) {
                        bitmap = Bitmap.createBitmap(view.getWidth(),
                                view.getHeight(), Bitmap.Config.ARGB_8888);
                        Canvas canvas = new Canvas(bitmap);
                    return bitmap;

Method 22

From Android 11 (API level 30) you can take screen shot with the accessibility service:

takeScreenshot – Takes a screenshot of the specified display and returns it via an AccessibilityService.ScreenshotResult.

Method 23

Take screenshot of a view in android.

public static Bitmap getViewBitmap(View v) {

    boolean willNotCache = v.willNotCacheDrawing();

    int color = v.getDrawingCacheBackgroundColor();

    if (color != 0) {
    Bitmap cacheBitmap = v.getDrawingCache();
    if (cacheBitmap == null) {
        return null;

    Bitmap bitmap = Bitmap.createBitmap(cacheBitmap);


    return bitmap;

Method 24

If you want to capture screenshot of a View, use View::drawToBitmap extension function:

val bitmap = myTargetView.drawToBitmap(/*Optional:*/ Bitmap.Config.ARGB_8888)

Only make sure to use the -ktx version of AndroidX Core library:


I’ve already answered a similar question like this here.

Method 25

If you want to capture a view or layout like RelativeLayout or LinearLayout etc.

Just use the code:

LinearLayout llMain = (LinearLayout) findViewById(;
Bitmap bm = loadBitmapFromView(llMain);

now you can save this bitmap on device storage by :

FileOutputStream outStream = null;
File f=new File(Environment.getExternalStorageDirectory()+"/Screen Shots/");
String extStorageDirectory = f.toString();
File file = new File(extStorageDirectory, "my new screen shot");
pathOfImage = file.getAbsolutePath();
try {
    outStream = new FileOutputStream(file);
    bm.compress(Bitmap.CompressFormat.PNG, 100, outStream);
    Toast.makeText(getApplicationContext(), "Saved at "+f.getAbsolutePath(), Toast.LENGTH_LONG).show();
} catch (FileNotFoundException e) {e.printStackTrace();}
try {
} catch (IOException e) {e.printStackTrace();}

Note: Use and implement solution 1 because this method fully tested our system.
