Question

我尝试使用Becons开发应用程序。我有this小的Estimote Beacon。我在this简短指令中描述了步骤。我从github下载了库，我将其添加到myproject中。

我的代码看起来像这样，

public class MainActivity extends Activity {

 BeaconManager beaconManager;

  private static final String ESTIMOTE_PROXIMITY_UUID = "B9407F30-F5F8-466E-AFF9-25556B57FE6D";
  private static final Region ALL_ESTIMOTE_BEACONS = new Region(ESTIMOTE_PROXIMITY_UUID, null, null);

  final String TAG = "MainActivity";
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Log.e(TAG, "onCreate");

    beaconManager = new BeaconManager(getApplicationContext());

    if(beaconManager.isBluetoothEnabled())
    {
        Toast.makeText(getApplicationContext(), "Bl włączone", Toast.LENGTH_LONG).show();
    }
    else
    {
        Toast.makeText(getApplicationContext(), "Bl wyłączone", Toast.LENGTH_LONG).show();
    }

      beaconManager.setRangingListener(new BeaconManager.RangingListener() {
        @Override public void onBeaconsDiscovered(Region region, List<Beacon> beacons) {
          Log.d(TAG, "Ranged beacons: " + beacons);
          Toast.makeText(MainActivity.this,"Ranged beacons: " + beacons, Toast.LENGTH_LONG).show();
        }           
      });
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
protected void onStart() {
    // TODO Auto-generated method stub
    super.onStart();
    Log.e(TAG, "onStart");
    beaconManager.connect(new BeaconManager.ServiceReadyCallback() {
        @Override public void onServiceReady() {
          try {
            beaconManager.startRanging(ALL_ESTIMOTE_BEACONS);
            Toast.makeText(getApplicationContext(), "try start ranging", Toast.LENGTH_LONG).show();

          } catch (RemoteException e) {
            Log.e(TAG, "Cannot start ranging", e);
            Toast.makeText(getApplicationContext(), "Cannot start ranging", Toast.LENGTH_LONG).show();
          }
        }
      });
}

@Override
protected void onStop() {
    // TODO Auto-generated method stub
    super.onStop();
      // Should be invoked in #onStop.
      try {
        beaconManager.stopRanging(ALL_ESTIMOTE_BEACONS);
      } catch (RemoteException e) {
        Log.e(TAG, "Cannot stop but it does not matter now", e);
        Toast.makeText(getApplicationContext(), "Cannot stop but it does not matter now", Toast.LENGTH_LONG).show();
      }


}

@Override
protected void onDestroy() {
    // TODO Auto-generated method stub
    super.onDestroy();
     // When no longer needed. Should be invoked in #onDestroy.
      beaconManager.disconnect();
}

}

</manifest>

显示在页面上，我收到此消息

02-22 05:27:08.711: A/BeaconManager(7227): Could not bind service

对我而言，这意味着创建BeaconManager会有问题，但不知道如何修复它。设备没有问题，因为我在iBeacon Locate应用程序扫描时看到了所有信标。我将不胜感激任何建议

您使用的是哪个版本的Estimote SDK？它是最新的0.4版本吗？将其检查为最新版本具有不同的日志标记。

如果日志显示“无法绑定服务”，则表示无法找到com.estimote.sdk.service.BeaconService。请注意，早期版本的SDK BeaconService位于com.estimote.sdk个包中，而不是com.estimote.sdk.service个。

BTW你能在Estimote SDK中运行Demos吗？
