Question

我使用Google Places API在Android上工作。我在运行PlaceDetectionApi的getCurrentPlace方法时遇到了问题。我在方法的PlaceLikelihoodBuffer中获得的resultcallback是空的，当我在我的logcat中打印errorstatus时，它说错误代码是13并且在logcat中，我也可以阅读＆＃34; D / PlaceInferenceEngine: No place inference engine is running, returning null"。我在模拟器上的AVD中运行它，遗憾的是我暂时无法在真实设备上测试它。所以，问题是：这个地方推理引擎是什么？如何让它在我的AVD上运行？

相关的代码是：

public void getCurrentPosition(int requestCode) {
        if(ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) !=
                PackageManager.PERMISSION_GRANTED) {
            ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.ACCESS_FINE_LOCATION},
                    requestCode);
        } else {
            if(requestCode == PERMISSION_REQUEST_GET_CURRENT_POSITION) {
                PendingResult<PlaceLikelihoodBuffer> result = Places.PlaceDetectionApi.getCurrentPlace(client, new PlaceFilter());
                result.setResultCallback(new ResultCallback<PlaceLikelihoodBuffer>() {
                    @Override
                    public void onResult(PlaceLikelihoodBuffer placeLikelihoods) {
                        System.out.println("inside callback...");
                        Status status = placeLikelihoods.getStatus();
                        System.out.println(status.isSuccess());
                        System.out.println(status.getStatusCode());
                        System.out.println(status.getStatusMessage());
                        for (PlaceLikelihood placeLikelihood : placeLikelihoods) {
                            Place place = placeLikelihood.getPlace();
                            System.out.println("possible place: " + place.getAddress());
                        }
                        placeLikelihoods.release();
                    }
                });
            }
         }
}

我的logcat中的结果是：

06-19 14:39:33.436 1865-2848/com.google.android.gms.persistent D/PlaceInferenceEngine: No place inference engine is running, returning null

放置检测api不适用于avd
