AutocompleteSupportFragment.setPlaceFields crushes App on start

Question

First,i'd like to say that i'm new in this "Programming world", but I've been struggling with autocompleteFragment by google Places, i'm trying to implement autocompleteFragment in my app, but after entering in my "Welcome Activity" it throws an error and crushes the App:

    Process: com.app.mk.transport, PID: 20295

And this is my code:

        if (!Places.isInitialized()) {
            Places.initialize(getApplicationContext(), String.valueOf(R.string.google_api_key));
        }
            autocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ADDRESS));


        autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {

            @Override
            public void onPlaceSelected(Place place) {

                if (location_switch.isChecked()) {
                    destination = place.getAddress();
                    destination = destination.replace(" ", "+");
                    getDirection();
                }
            }

            @Override
            public void onError(Status status) {
                // TODO: Handle the error.
                Toast.makeText(Welcome.this, "" + status.toString(), Toast.LENGTH_SHORT).show();
                Log.i(TAG, "An error occurred: " + status);
            }
        });

i'm not sure what I'm doing wrong but if someone could point out what's my mistake i would really appreciate it.

And if i need to show you something else "code" or anything just tell me if i'm missing it out!

Thank you.

Have you found the solution? I am facing the same error – AbhayBohra Apr 15 '19 at 08:28 — AbhayBohra, Apr 15 '19 at 08:28

Hi this issues comes when implementing in fragment .Use getChildFragmentManager instead of getSupportFragmentManager/getFragmentManger(). This will work perfectly.Like this:-

if (!Places.isInitialized()) {
        Places.initialize(getApplicationContext(), "YOUR_API_KEY");
    }


// Initialize the AutocompleteSupportFragment.

AutocompleteSupportFragment autocompleteFragment = (AutocompleteSupportFragment)
        getChildFragmentManager().findFragmentById(R.id.autocomplete_fragment);


autocompleteFragment.setPlaceFields(Arrays.asList(Place.Field.ID, Place.Field.NAME));


autocompleteFragment.setOnPlaceSelectedListener(new PlaceSelectionListener() {
    @Override
    public void onPlaceSelected(Place place) {
        // TODO: Get info about the selected place.
        Log.i(TAG, "Place: " + place.getName() + ", " + place.getId());
    }

    @Override
    public void onError(Status status) {
        // TODO: Handle the error.
        Log.i(TAG, "An error occurred: " + status);
    }
});

This worked for me hope this will also worked for you. Thanks....

If you are using into activity then Use <androidx.fragment.app.FragmentContainerView> instead < <fragment> tag.

And for add implementation "androidx.fragment:fragment:1.2.0" dependency.
