How to programmatically take a screenshot on Android?

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:
