我正在使用Context来访问WifiManager和BluetoothManager等系统级服务.如何使用Mockito模拟这个getApplicationContext()？

我正在尝试使用Gimbal sdk创建一个Android应用程序来检测基于Gimbal的信标,但我的应用程序无法检测到信标.但如果我尝试使用BluetoothGATT,我就能够检测到信标.以下是我的代码中侦听信标事件的部分.API密钥验证成功,但仍然无法显示邻近度.

public class MainActivity extends Activity {

    private PlaceManager placeManager;
    private PlaceEventListener placeEventListener;
    private BeaconEventListener beaconEventListener;
    private BeaconManager beaconManager;
    private String TAG = "beacon";

    public ArrayAdapter<String> listAdapter;
    public ListView listView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        Gimbal.setApiKey(getApplication(),
                "MY API KEY ");
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        initView();

        monitorPlace();

        listenBeacon();



        CommunicationManager.getInstance().startReceivingCommunications();

    }

    private void listenBeacon() {
        BeaconEventListener beaconEventListener = getBeaconEventListener();
        BeaconManager beaconManager = new BeaconManager();
        beaconManager.addListener(beaconEventListener);
        beaconManager.startListening();
    }

    private void monitorPlace() {
        placeEventListener = getPlaceEventListener();

        // placeManager = PlaceManager.getInstance();
        // placeManager.addListener(placeEventListener);
        placeManager = …

我有两个多行字符串.我正在使用以下代码来确定其中两个之间的相似性.这利用了Levenshtein距离算法.

  public static double similarity(String s1, String s2) {
    String longer = s1, shorter = s2;
    if (s1.length() < s2.length()) { 
      longer = s2; shorter = s1;
    }
    int longerLength = longer.length();
    if (longerLength == 0) { return 1.0; /* both strings are zero length */ }

    return (longerLength - editDistance(longer, shorter)) / (double) longerLength;

  }

  public static int editDistance(String s1, String s2) {
    s1 = s1.toLowerCase();
    s2 = s2.toLowerCase();

    int[] costs = new int[s2.length() + 1];
    for (int i …

我创建了一个Android应用程序,使用蓝牙LE扫描程序扫描BLE.现在我需要我的应用程序来识别信标是否属于iBeacon或Eddystone.到目前为止,我通过解析AD帧成功地确定了ibeacon的UUID,MajorId,MinorId.
