小编Alp*_*pan的帖子

我正在android中开发一个聊天应用程序.使用XMPP服务器.PHP服务器已迁移到ejabber.

我的通知在所有情况下都能正常运行 但在一个案例中,我正在丢失XMPP消息.事实上我没有收到通知.

详细说来,我正在关闭WiFi或数据连接.关闭WiFi或数据连接后,发送给我的任何通知都没有收到.在我打开WiFi或数据连接后,我无法收到发送给我的消息.

我已经在后台实施了服务.这使得xmpp连接永远存在.

我关闭WiFi连接时收到此错误.

在我的应用程序中,我将实现Google Maps示例

然而:

1. 当我直接运行应用程序时,地图将完美运行
2. 虽然我可以制作标志apk(制作密钥存储文件并与密钥存储Apk相关)然后地图将无法正常工作

对于这个问题,我尝试了很多想法

1. 创建我的应用程序的另一个和另一个与包相关的API KEY
2. 在Android Manifest文件中添加额外的权限(下面给出了最新的Manifest权限)

有人可以帮忙吗？

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".CountryRequirement" >

<fragment
    android:id="@+id/map"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.MapFragment" />

</RelativeLayout>

我的XML布局包含此内容
我提供了Google Maps示例中所需的所有权限

我的清单文件:
