是的，我知道这个问题已经在很多地方得到了回答，但我没有遇到什么问题，我最近搬到了Android应用程序并试图在我的应用程序上使用地图。
我完全按照这些链接：
https://www.youtube.com/watch?v=wNlleczyPjs
所以我的问题是，我还能做些什么呢。我只是不明白......
我的感觉是我的密钥没有正确注册，但是当我创建新密钥时，我提供了以下信息：
Android apps:
9D:7C:<THIS BIT IS SECRET>84:0F;com.example.myapp
额外信息
这是错误日志：

这是代码：
package com.example.myapp;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
public class MainActivity extends FragmentActivity{
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

}
这是androidManifext.xml

提前致谢。
IT工作 耶稣，它刚开始没有在哪里工作。日食刚刚上市，我花了大约10分钟让日食工作。现在它刚开始工作，应用程序也是如此。我不知道发生了什么，也不知道为什么它会让我烦恼。基本上我只能说api键上班需要几个小时。

我不确定这是否是造成问题的原因但是我觉得你的main_activity.xml没有布局容器，例如LinearLayout，RelativeLayout ..
您可以尝试使main_activity.xml看起来像这样，看看会发生什么：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical">
<fragment
android:id="@+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
class="com.google.android.gms.maps.SupportMapFragment"/>
</LinearLayout>
或者我建议尝试使用vogella http://www.vogella.com/tutorials/AndroidGoogleMaps/article.html的教程，它对我来说非常有用。
再次阅读错误日志，我想知道您是否已将支持库添加到项目中。在eclipse中它就像：Rightclick项目 - ＆gt; Android工具 - ＆gt;添加支持库...

plz添加此权限然后才能使用
<permission
android:name="<your package name>.permission.MAPS_RECEIVE"
android:protectionLevel="signature" />
<uses-permission android:name="<your package name>.permission.MAPS_RECEIVE" />
<uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" />
答案 2 :(得分：0)
我正在使用......
<LinearLayout 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"
android:orientation="vertical" >
<fragment
android:id="@+id/map"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
class="com.google.android.gms.maps.MapFragment" />
它适用于我
