关于应用程序: - 这是一个简单的应用程序,它可以找到用户当前的位置。Android地图查看手机和模拟器不同
问题: - 该应用程序在仿真器上正常工作,请参阅图像。
但在手机它没有显示在MapView.Please看到图像。
请告诉我什么是与手机脚麻。在手机中,只需下载巨大(20 MB)的数据,但不显示实际的地图。

我只是一个装箱API密钥如下goto->命令提示符
变化的目录密钥工具夹
现在运行命令密钥工具-list -alias androiddebugkey -keystore “C:\用户\ pc.android \ debug.keystore” -storepass机器人-keypass机器人
看到图像
现在我转到注册页面我只是把EditText上的MD5和检查接受并点击生成密钥,然后下面的页面出现这显示key--
现在我把这个密钥放在我的MapView Xml文件中。
你可以看到应用在模拟器中运行正常,但在真实手机中没有。
我在哪里出错,以及如何为真实手机生成第二个API密钥?
手机中的应用程序是通过android市场下载的?或者它是您使用的调试.apk?你知道你必须用有效的密钥签署你的地图,而不是调试密钥吗? – Ivan
是的,我用有效的api密钥签署我的应用程序 – Sunny
该应用程序在市场上?如果答案是肯定的,那么API密钥必须与用于签署应用程序的密钥相同。 – Ivan
