Android地理围栏退出/进入地理围栏事件未触发

标签 android google-maps-android-api-2 google-api-client android-geofence

我被这个问题困扰了一个多星期。Goefence 事件不会在进入或存在 Geofence 时触发。我已经在模拟器上测试了几次。

这是我的 MainActivity

非常感谢任何帮助。

最佳答案

您的代码很好，只需使用真实设备，并启用 GPS，还授予应用位置权限，设置，我使用模拟器之前它不适合我。

更新

我试过你的代码，有一些地方可以解决这个问题，首先在 list 中添加这段代码

<application
    android:allowBackup="true"
    android:icon="@mipmap/ic_launcher"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/ic_launcher_round"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">
    <!-- add this -->
    <meta-data android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />
    <activity android:name=".MainActivity">

在您的服务中删除 Toast 并使用日志只是因为它崩溃了应用程序，这就是结果 enter image description here

我添加 GeofencingRequest.INITIAL_TRIGGER_EXIT对于 GeofencingRequest只是为了确保它能完美地工作

    private GeofencingRequest getGeofencingRequest() {
    Log.d(TAG,"Inside Getgeofencing request");
    GeofencingRequest.Builder builder = new GeofencingRequest.Builder();
    builder.setInitialTrigger(GeofencingRequest.INITIAL_TRIGGER_ENTER | GeofencingRequest.INITIAL_TRIGGER_EXIT);
    builder.addGeofences(mGeofenceList);
    return builder.build();
}

在 list 中我添加了这个权限 - 我想你已经添加了它，以防万一 - <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
