当我尝试运行应用程序并单击按钮时，Logcat 会给我这些消息:

03-31 10:32:29.254 2591-2591/pounya.id.location3 V/Main Activity: Permision is granted

Constant.java 中使用的坐标是我家的坐标。我尝试从我家出去(超过 1 公里)然后回到我家，我没有收到任何通知或 Toast。

我不知道根本问题是什么。我使用了运行权限并在 AndroidManifest.xml 中插入 GeoFenceTransitionsIntentService

有人能帮我弄清楚吗？感谢您的帮助。我花了很多时间来解决这个问题，但我仍然无法解决。

遇到了同样的问题。由于 Android 8 后台工作更加有限。有一种调用 IntentService 的新方法。查看有关实现地理围栏监听器的最新 Android 指南:

https://developer.android.com/training/location/geofencing

简而言之，您只需要使用GeofencingClient 来调用包含IntentService 的PendingIntent。

private PendingIntent getGeofencePendingIntent() {
    // Reuse the PendingIntent if we already have it.
    if (mGeofencePendingIntent != null) {
        return mGeofencePendingIntent;
    }
    Intent intent = new Intent(this, GeofenceTransitionsIntentService.class);
    // We use FLAG_UPDATE_CURRENT so that we get the same pending intent back when
    // calling addGeofences() and removeGeofences().
    mGeofencePendingIntent = PendingIntent.getService(this, 0, intent, PendingIntent.
            FLAG_UPDATE_CURRENT);
    return mGeofencePendingIntent;
}
