我正在尝试为狂暴的信标做一个简单的应用程序，但是当我启动该应用程序时它会停止。我想我用“添加外部 jar”正确导入了 sdk。

进口的sdk

我更改了 android manifest 来做蓝牙权限和其他事情......

<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
...
<service android:name="com.estimote.sdk.service.BeaconService" android:exported="false"/>

这是错误日志：

我不知道为什么它说找不到类'com.estimote.sdk.Region'......

这是主要活动

package com.example.beacons;

import java.util.List;

import com.estimote.sdk.Beacon;
import com.estimote.sdk.BeaconManager;
import com.estimote.sdk.Region;

import android.os.Bundle;
import android.os.RemoteException;
import android.app.Activity;
import android.view.Menu;
import android.view.View;
import android.widget.Toast;

public class MainActivity extends Activity {
    private static final String ESTIMOTE_PROXIMITY_UUID = "B9407F30-F5F8-466E-AFF9-25556B57FE6D";
    private static final Region ALL_ESTIMOTE_BEACONS = new Region("regionId", ESTIMOTE_PROXIMITY_UUID, null, null);

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    @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;
    }

    public void bluetoothTest(View view){
        Toast.makeText(getBaseContext(),"Listener works", Toast.LENGTH_SHORT).show();
    }

}

如果我删除这一行：

private static final Region ALL_ESTIMOTE_BEACONS = new Region("regionId", ESTIMOTE_PROXIMITY_UUID, null, null);

一切正常，触摸屏幕上的 1 个按钮时我可以看到吐司。

Eclipse 出于某种原因没有将 jar 打包到 apk 中。

请参阅：https ://stackoverflow.com/a/11003202或https://stackoverflow.com/a/14125846或在 Android 项目中引用（纯 java）项目（找不到类）

我遇到了同样的麻烦。就我而言，是使用 Unity3D 和 estimote 服务。关键是给currentActivity添加一个没有UI的fragment。

示例：这在启动信标的文件中。在您的情况下，如果您从活动中执行此操作，则可以擦除 UnityPlayer.currentActivity，因为此示例用于与统一项目混合

    fragment = new BeaconsFragment();
    android.app.FragmentManager fragmentManager = UnityPlayer.currentActivity.getFragmentManager();
    FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    fragmentTransaction.add(fragment, "thread_beacons");
    fragmentTransaction.commit()
