PlacePicker를 호출하는 동안 NullPointerException이 발생했습니다.

Gradle 종속성 :

compile "com.google.android.gms:play-services-location:11.0.0"

자바:

private void showPlacePicker() {
        PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();
        try {
            startActivityForResult(builder.build(this), PLACE_PICKER_REQUEST);
        } catch ( GooglePlayServicesRepairableException e ) {
            Log.d( "PlacesAPI Demo", "GooglePlayServicesRepairableException thrown" );
        } catch ( GooglePlayServicesNotAvailableException e ) {
            Log.d( "PlacesAPI Demo", "GooglePlayServicesNotAvailableException thrown" );
        }
    }

나는 또한 활성화했다 Google Places API for Android. 그리고 그 키를 사용하여 Google지도를로드했기 때문에 API 키 통합에 문제가 있다고 생각하지 마십시오. 그럼에도 불구하고 메서드 showPlacePicker()가 호출 되 자마자 ; 앱이 충돌합니다.
