不幸的是，[Beacon Project name] 已经停止

Question

当我尝试运行我的信标查找器项目时出现以下错误：

Unfortunately, Beacon Project has stopped.

这是我的 logcat:

这是我的清单：

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
          package="project.rssi.beacon.com.beaconproject">

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN"/>

                <category android:name="android.intent.category.LAUNCHER"/>
            </intent-filter>
        </activity>
    </application>

    <uses-permission android:name="android.permission.BLUETOOTH"/>
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

</manifest>

代码没有问题，我猜，我认为这是 Android Studio 中的一种错误，但无法弄清楚。

根据治疗

You must create a class that extends Application (shown in the example) and then declare this in your AndroidManifest.xml.

因此创建一个 class 扩展应用程序 class 并将其添加到清单中。android:name="com.example.MyApplicationName"

也将此添加到您的 activity android:launchMode="singleInstance"

应用程序 class 的示例是：

public class MyApplicationName extends Application implements BootstrapNotifier {
private static final String TAG = ".MyApplicationName";
private RegionBootstrap regionBootstrap;

@Override
public void onCreate() {
    super.onCreate();
    Log.d(TAG, "App started up");
    BeaconManager beaconManager = 
    BeaconManager.getInstanceForApplication(this);


}

@Override
public void didDetermineStateForRegion(int arg0, Region arg1) {
    // Don't care
}

@Override
public void didEnterRegion(Region arg0) {

    regionBootstrap.disable();
    Intent intent = new Intent(this, MainActivity.class);
    // IMPORTANT: in the AndroidManifest.xml definition of this activity, you must set android:launchMode="singleInstance" or you will get two instances
    // created when a user launches the activity manually and it gets launched from here.
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    this.startActivity(intent);
}

@Override
public void didExitRegion(Region arg0) {

  }        
}
