एपि> 19 के लिए छवि और वीडियो कैसे चुनें

यहाँ छवि और वीडियो के लिए एक परीक्षण कोड दिया गया है। यह 19 से कम सभी एपीआई और 19 से अधिक के लिए भी काम करेगा।

छवि:

if (Build.VERSION.SDK_INT <= 19) {
                        Intent i = new Intent();
                        i.setType("image/*");
                        i.setAction(Intent.ACTION_GET_CONTENT);
                        i.addCategory(Intent.CATEGORY_OPENABLE);
                        startActivityForResult(i, 10);
                    } else if (Build.VERSION.SDK_INT > 19) {
                        Intent intent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
                        startActivityForResult(intent, 10);
                    }
