我尝试了三天但我的问题没有解决!我正在使用Google API地图v2制作应用,我成功激活了它...
现在,当我运行我的程序时,它显示此错误:“不幸的是,应用程序已停止”
请帮助这是什么样的错误??
这是一个清单文件:

在您的代码中,您应该在GoogleMap
中对您的地图进行充气,除了您正在将其膨胀为Fragment
之外,该地图已经变为SupportMapFragment
。
更改以下行:
mMap = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
googleMap = mMap.getMap();
如下:
googleMap = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map).getMap();
使用GoogleMap
的实例而不是SupportMapFragment
。好像您将使用SupportMapFragment
一样,它总是会搜索您为布局中的Fragment
定义的类。并将搜索getMap()
的方法,这是GoogleMap
类的方法。

确保您的项目中有以下库。
将play-services-libs添加为项目。
在构建路径中添加库。

答案 2 :(得分:0)
xml
中的第一次更改更改此行
android:name="com.google.android.gms.maps.SupportMapFragment"
到
class="com.google.android.gms.maps.SupportMapFragment"
manifest
中的 第二次更改将此内容添加到application tag
<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
最重要的是,您已将
google-play-sevice-lib
添加到您的项目中
检查API-Key
是否已使用您的计算机的SHA-1生成Google console
;您的包名称是
如何import
google_play_services_lib
确保ur project and library present in same worksapce

在实施Google Play服务api期间,不幸的是,应用已停止错误的确定镜头解决了答案:
主要活动:
import com.google.android.gms.location.LocationListener;
而不是
import android.location.LocationListener;
在依赖项中使用这些:(构建gradle文件)
compile 'com.android.support:appcompat-v7:21.0.3'
compile 'com.android.support:support-v4:23.0.1'
compile 'com.google.android.gms:play-services:11.0.1'
compile 'com.android.support:multidex:1.0.0'
Android清单文件:
<meta-data
android:name="com.google.android.geo.API_KEY"
android:value="@string/google_maps_key" />
<meta-data android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
