我尝试使用 Becons 开发应用程序。我有这个小的 Estimote Beacon。我做了这个简短说明中描述的步骤。我从github下载了这个库，我把它添加到了我的项目中。
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();
}
}

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
对我来说，这意味着创建 BeaconManager 有问题，但不知道如何解决。设备没有问题，因为当我通过iBeacon Locate应用程序扫描它时，我看到了所有信标。我将不胜感激任何建议
