Android Place Picker

Question

我无法在我的应用中使用地方选择器。 API工作然后停止了一天没有任何解释。选择器显示很短的时间然后只是关闭，没有例外，日志中没有任何内容。我还为Android启用了google places api。

主要活动

public class MainActivity extends FragmentActivity implements OnMapReadyCallback {

private GoogleMap mMap;
int PLACE_PICKER_REQUEST = 1;

private Button add;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    // Obtain the SupportMapFragment and get notified when the map is ready to be used.
    SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
            .findFragmentById(R.id.map);
    mapFragment.getMapAsync(this);

    add = (Button) findViewById(R.id.add);
    add.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            PlacePicker.IntentBuilder builder = new PlacePicker.IntentBuilder();

            try {
                startActivityForResult(builder.build(MainActivity.this), PLACE_PICKER_REQUEST);
            } catch (GooglePlayServicesRepairableException e) {
                e.printStackTrace();
            } catch (GooglePlayServicesNotAvailableException e) {
                e.printStackTrace();
            }
        }
    });
}


/**
 * Manipulates the map once available.
 * This callback is triggered when the map is ready to be used.
 * This is where we can add markers or lines, add listeners or move the camera. In this case,
 * we just add a marker near Sydney, Australia.
 * If Google Play services is not installed on the device, the user will be prompted to install
 * it inside the SupportMapFragment. This method will only be triggered once the user has
 * installed Google Play services and returned to the app.
 */
@Override
public void onMapReady(GoogleMap googleMap) {
    mMap = googleMap;

    if (mMap == null)
        return;

    MarkerOptions options = new MarkerOptions();
    //Need to add new lat long here
    ArrayList<LatLng> latlngs = new ArrayList<>();
    latlngs.add(new LatLng(12.334343, 33.43434));
    latlngs.add(new LatLng(28.704059, 77.102490));
    latlngs.add(new LatLng(19.075984, 72.877656));

    // Add a marker in Sydney and move the camera
    LatLng sydney = new LatLng(-34, 151);
    for (LatLng point : latlngs) {
        options.position(point);
        options.title("someTitle");
        options.snippet("someDesc");
        googleMap.addMarker(options);
    }
    mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney));
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == PLACE_PICKER_REQUEST) {
        if (resultCode == RESULT_OK) {
            Place place = PlacePicker.getPlace(data, this);
            String toastMsg = String.format("Place: %s", place.getName());
            Toast.makeText(this, toastMsg, Toast.LENGTH_LONG).show();
        }
    }
}

}

这很可能是API密钥/配额问题。调用（if）onActivityResult()时会得到什么resultCode？

您可以尝试启用“地方信息”的详细日志记录，这可能会记录可让您更深入了解问题原因的内容
