我正在尝试编写一些使用Google Maps API的应用程序。地图显示在主要活动中。
在某些手机上，包括模拟器，应用程序在启动后立即崩溃。它唯一使用的手机是我的Galaxy S1，它运行CM10.1（4.2.2）。
它崩溃了我的HTC DESIRE HD（4.2.2）

答案 0 :(得分：6)
只需执行以下操作即可检查Google Play服务是否可用：
int status = GooglePlayServicesUtil.isGooglePlayServicesAvailable(getApplicationContext());
if(status == ConnectionResult.SUCCESS) {
//Success! Do what you want
}else{
GooglePlayServicesUtil.getErrorDialog(status, this, status);
}
它会检查谷歌播放服务，如果没有，它会提示用户从谷歌播放下载它们
答案 1 :(得分：3)
听起来好像您正在测试的手机没有安装最新的Google Play服务预先要求。
如果您查看here，您会找到一个部分，讨论如何确保设备安装了Google Play服务APK，如果没有，请指示用户安装它。
另请注意，运行API平台的模拟器不支持模拟器，而不是Andorid 4.2.2（在第一部分中引用here）
答案 2 :(得分：2)
GoogleApiAvailability googleApiAvailability=GoogleApiAvailability.getInstance();
int status=googleApiAvailability.isGooglePlayServicesAvailable(getActivity());
if (status != ConnectionResult.SUCCESS) {
int requestCode = 10;
Dialog dialog = googleApiAvailability.getErrorDialog(getActivity(),status,requestCode);
dialog.show();
}else{}
答案 3 :(得分：1)
请参阅here以查看手机上提供的Google Play服务。如果您遇到错误，则会显示从Google Play服务返回的错误对话框。我已经使用三星Galaxy S3上的Google Maps v2处理我的应用程序并且工作正常。
