Question

我正在创建一个简单的Android应用程序，我想显示谷歌地图，所以我使用谷歌地图的活动，但当我在我的设备上运行应用程序时，我得到一个空白的屏幕与谷歌写在左下方。我使用了正确的API密钥。这是Logcat。我也找不到了＆＃34; Google Maps Android API v2＆＃34;在Google Developer Console中。只有我已启用的Google Maps Android API。

我还在谷歌地图键中给出了api键。

Answer 1

搜索了好几个小时后，我知道我已将.android文件夹从C: drive移到D: drive，并将ANDROID_SDK_HOME设置为新路径，但我没有＆删除上一个文件夹。我使用上一个路径来获取不正确的Certificate fingerprints: Md5 ,SHA1。这是我所做的唯一一次尝试，这就是Sha1不匹配的原因。

早些时候我正在使用这个

keytool -list -v -keystore "C:\.android\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

获取证书指纹，但现在我使用正确的路径

keytool -list -v -keystore "D:\.android\.android\debug.keystore" -alias androiddebugkey -storepass android -keypass android

必须在console.developers.google.com上再次按照相同的步骤获取API密钥，现在我可以在屏幕上显示地图。

Answer 2

您应该在google开发者控制台上启用“Google Maps Android API v2”API，并在Google控制台上生成任何Android密钥（API密钥：AIzaSyA2PEin-GiKaerDpnoStcvKGmCmHJ2cZuI），您应该将其放在清单文件中。

无法在Android的谷歌地图活动
