How to programmatically take a screenshot in Android?

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

Answer Source

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

First, add proper permission to save 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 OOM

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/*");
