If you get to face the errors, why don't we? Also, did you *mean* to enclose your code with single quotes? — , Oct 15 '14 at 04:38

Thanks allot MEENAL SHARMA and JEREMY no i didn't close the code in single code in my program.. errors are in when I am adding the pakage name meri_application — Malaika Khan, Oct 15 '14 at 04:52
@Meenal Sharma yes i viewed and want to know that it will save the pic in folder but i am not able to view it and dont know where it is saving its screenshots i found the folder but no image were their — Malaika Khan, Oct 15 '14 at 09:59

You can try with this:

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

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

OutputStream fout = null;
imageFile = new File(mPath);

try {
    fout = new FileOutputStream(imageFile);
    bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fout);
    fout.flush();
    fout.close();

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

this answer is taken from this: How to programmatically take a screenshot in Android?

Explanation: Output image path with image name:

String mPath = Environment.getExternalStorageDirectory().getPath() + "/" + "ScreenShot.jpg";

Get the Screen Image of current view/display and create the bitmap from this:

Bitmap bitmap;
View v1 = getWindow().getDecorView().getRootView(); // View v1 = mCurrentUrlMask.getRootView();
v1.setDrawingCacheEnabled(true);
bitmap = Bitmap.createBitmap(v1.getDrawingCache());
v1.setDrawingCacheEnabled(false);

and finally save & compress the image:

try {
    fout = new FileOutputStream(imageFile);
    bitmap.compress(Bitmap.CompressFormat.JPEG, 90, fout);
    fout.flush();
    fout.close();

}

I have already viewed this but I am not able to understand it its little complex or may be I am not understanding it properly but somehow this is the problem — Malaika Khan, Oct 15 '14 at 04:54
please, see my explanation... I think this will help you little bit. — Md. Shahadat Sarker, Oct 15 '14 at 05:16
please tell me that where the screenshots are going to be saved and where i would find my folder. and how would i know about that the screenshots of the screen are captured — Malaika Khan, Oct 15 '14 at 10:22
check it into your device root directory. Environment.getExternalStorageDirectory().getPath() with return device root directory (External SD Card). — Md. Shahadat Sarker, Oct 15 '14 at 10:34

just replace save bitmap method with this

public void saveBitmap(Bitmap bitmap) {

    try {
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
        File f = new File(Environment.getExternalStorageDirectory()
                + File.separator + "test.jpg");
        f.createNewFile();
        FileOutputStream fo = new FileOutputStream(f);
        fo.write(bytes.toByteArray());
        fo.close();
    } catch (FileNotFoundException e) {
        Log.e("GREC", e.getMessage(), e);
    } catch (IOException e) {
        Log.e("GREC", e.getMessage(), e);
    }
}

Edit 1:

just replcae your code with this code

    @Override
public void onClick(View v) {
    // TODO Auto-generated method stub
    if (v.getId() == R.id.btnTakeScreenShot) {
        Bitmap bitmap = takeScreenshot()
        imageView.setImageBitmap(bitmap);

        saveBitmap(bitmap);


    }
}


public Bitmap takeScreenshot() {
    View rootView = findViewById(android.R.id.content).getRootView();
    rootView.setDrawingCacheEnabled(true);
    return rootView.getDrawingCache();
}
public void saveBitmap(Bitmap bitmap) {

    try {
        ByteArrayOutputStream bytes = new ByteArrayOutputStream();
        bitmap.compress(Bitmap.CompressFormat.JPEG, 40, bytes);
        File f = new File(Environment.getExternalStorageDirectory()
                + File.separator + "test.jpg");
        f.createNewFile();
        FileOutputStream fo = new FileOutputStream(f);
        fo.write(bytes.toByteArray());
        fo.close();
    } catch (FileNotFoundException e) {
        Log.e("GREC", e.getMessage(), e);
    } catch (IOException e) {
        Log.e("GREC", e.getMessage(), e);
    }
}

you have implemented the same code as in the link i have mentioned, because i have tried it and it is working, just done some changes in save bitmap method. — Meenal, Oct 15 '14 at 11:43
can you paste your code here..just edit your question and paste your code there.. — Meenal, Oct 16 '14 at 04:42
oh thanks allot MEENAL SHARMA it is working now but overwriting the same image. please tell me how to ask user to set different name for different screenshots — Malaika Khan, Oct 16 '14 at 11:15
just change the name text.jpg to user given name..show and alert dialog to user to enter name for image — Meenal, Oct 16 '14 at 11:17
