Answer 1

    final View content = findViewById(R.id.layoutFP);
    content.setDrawingCacheEnabled(true);
    Bitmap bitmap = content.getDrawingCache();
    String root = Environment.getExternalStorageDirectory().toString();
    File myDir = new File(root + "/saved_images");    
    myDir.mkdirs();
    Random generator = new Random();
    int n = 10000;
    n = generator.nextInt(n);
    String fname = "Image-"+ n +".jpg";
    File file = new File (myDir, fname);
    if (file.exists ()) file.delete (); 
    try {
           FileOutputStream out = new FileOutputStream(file);
           bitmap.compress(Bitmap.CompressFormat.JPEG, 90, out);
           out.flush();
           out.close();
           content.invalidate(); 
           sendBroadcast(new Intent(Intent.ACTION_MEDIA_MOUNTED, Uri.parse("file://"+ Environment.getExternalStorageDirectory())));

    } catch (Exception e) {
           e.printStackTrace();
    }finally{
        content.setDrawingCacheEnabled(false);                          
    }

Finally add permission in your Manifest file:

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

Answer 2

You've got a Bitmap object in your fingerPaint class. Instantiate a FileOutputStream to the location you'd like to save to, and call mBitmap.compress method with the appropriate options and your output stream. Remember to close your stream.

Here is the source code to do that

LinearLayout v = (LinearLayout) findViewById(R.id.mainLayout);
v.setDrawingCacheEnabled(true);
// this is the important code :)
// Without it the view will have a
// dimension of 0,0 and the bitmap will
// be null
v.measure(MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED), MeasureSpec.makeMeasureSpec(0, MeasureSpec.UNSPECIFIED));
v.layout(0, 0, v.getWidth(), v.getHeight());
v.buildDrawingCache(true);
Bitmap bm = Bitmap.createBitmap(v.getDrawingCache());
v.setDrawingCacheEnabled(false);
if (bm != null) {
    try {
        String path = Environment.getExternalStorageDirectory().toString();
        OutputStream fOut = null;
        File file = new File(path, "screentest.jpg");
        fOut = new FileOutputStream(file);
        bm.compress(Bitmap.CompressFormat.JPEG, 85, fOut);
        fOut.flush();
        fOut.close();
        Log.e("ImagePath", "Image Path : " + MediaStore.Images.Media.insertImage( getContentResolver(), file.getAbsolutePath(), file.getName(), file.getName()));
    }
    catch (Exception e) {
        e.printStackTrace();
    }
}

Hope this will work with you also.
