Question

I am facing the problem while retrieving the contacts from the contact book in Android 8.0 Oreo java.lang.IllegalStateException: Only fullscreen opaque activities can request orientation

I am trying to get the contact in my activity from the phone contact book and it works perfect for Lollipop, Marshmallow, Nougat, etc but it will gives me the error for Oreo like this please help me. My code is here below.

Demo Code :-

private void loadContacts() {

            contactAsync = new ContactLoaderAsync();

            contactAsync.execute();

        }

        private class ContactLoaderAsync extends AsyncTask<Void, Void, Void> {

            private Cursor numCursor;

            @Override

            protected void onPreExecute() {

                super.onPreExecute();

                Uri numContacts = ContactsContract.CommonDataKinds.Phone.CONTENT_URI;

                String[] numProjection = new String[]{ContactsContract.CommonDataKinds.Phone.CONTACT_ID, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME, ContactsContract.CommonDataKinds.Phone.NUMBER, ContactsContract.CommonDataKinds.Phone.TYPE};

                if (android.os.Build.VERSION.SDK_INT < 11) {

                    numCursor = InviteByContactActivity.this.managedQuery(numContacts, numProjection, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " COLLATE NOCASE ASC");

                } else {

                    CursorLoader cursorLoader = new CursorLoader(InviteByContactActivity.this, numContacts, numProjection, null, null, ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME + " COLLATE NOCASE ASC");

                    numCursor = cursorLoader.loadInBackground();

                }

            }

            @Override

            protected Void doInBackground(Void... params) {

                if (numCursor.moveToFirst()) {

                    try {

                        final int contactIdIndex = numCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.CONTACT_ID);

                        final int displayNameIndex = numCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.DISPLAY_NAME);

                        final int numberIndex = numCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.NUMBER);

                        final int typeIndex = numCursor.getColumnIndex(ContactsContract.CommonDataKinds.Phone.TYPE);

                        String displayName, number, type;

                        do {

                            displayName = numCursor.getString(displayNameIndex);

                            number = numCursor.getString(numberIndex);

                            type = getContactTypeString(numCursor.getString(typeIndex), true);

                            final ContactModel contact = new ContactModel(displayName, type, number);

                            phoneNumber = number.replaceAll(" ", "").replaceAll("\\(", "").replaceAll("\\)", "").replaceAll("-", "");

                            if (phoneNumber != null || displayName != null) {

                                contacts.add(phoneNumber);

                                contactsName.add(displayName);

                                contactsChecked.add(false);

                                filterdNames.add(phoneNumber);

                                filterdContactNames.add(displayName);

                                filterdCheckedNames.add(false);

                            }

                        } while (numCursor.moveToNext());

                    } finally {

                        numCursor.close();

                    }

                }

                Collections.sort(contacts, new Comparator<String>() {

                    @Override

                    public int compare(String lhs, String rhs) {

                        return lhs.compareToIgnoreCase(rhs);

                    }

                });

                InviteByContactActivity.this.runOnUiThread(new Runnable() {

                    @Override

                    public void run() {

                        mContactAdapter.notifyDataSetChanged();

                    }

                });

                return null;

            }

        }

        private String getContactTypeString(String typeNum, boolean isPhone) {

            String type = PHONE_TYPES.get(typeNum);

            if (type == null)

                return "other";

            return type;

        }

        static HashMap<String, String> PHONE_TYPES = new HashMap<String, String>();

        static {

            PHONE_TYPES.put(ContactsContract.CommonDataKinds.Phone.TYPE_HOME + "", "home");

            PHONE_TYPES.put(ContactsContract.CommonDataKinds.Phone.TYPE_MOBILE + "", "mobile");

            PHONE_TYPES.put(ContactsContract.CommonDataKinds.Phone.TYPE_WORK + "", "work");

        }

}

Google throws this exception on Activity's onCreate method after v27, their meaning is : if an Activity is translucent or floating, its orientation should be relied on parent(background) Activity, can't make decision on itself.

Even if you remove android:screenOrientation="portrait" from the floating or translucent Activity but fix orientation on its parent(background) Activity, it is still fixed by the parent, I have tested already.

One special situation : if you make translucent on a launcher Activity, it has't parent(background), so always rotate with device. Want to fix it, you have to take another way to replace <item name="android:windowIsTranslucent">true</item> style.
