Question

我在这里得到2个错误，首先是“无法启动活动”，第二个是“找不到API密钥”。我搜索了很多解决方案，但没有解决问题.API密钥是正确的但仍然是我不知道为什么会出现错误。任何人都可以告诉我代码中有什么问题吗？

Answer 1

替换此

<meta-data
            android:name="com.google.android.maps.v2.AIzaSyBQeTS1IcCPtJxCGvFC4o-Ud5fJHdUmRCY"
            android:value="AIzaSyBQeTS1IcCPtJxCGvFC4o-Ud5fJHdUmRCY"/>

与

 <meta-data
            android:name="com.google.android.maps.v2.API_KEY"
            android:value="AIzaSyBQeTS1IcCPtJxCGvFC4o-Ud5fJHdUmRCY" />

Answer 2

更改

<meta-data
android:name="com.google.android.maps.v2.AIzaSyBQeTS1IcCPtJxCGvFC4o-Ud5fJHdUmRCY"
android:value="AIzaSyBQeTS1IcCPtJxCGvFC4o-Ud5fJHdUmRCY"/>

应该是

<meta-data
android:name="com.google.android.maps.v2.API_KEY"
android:value="AIzaSyBQeTS1IcCPtJxCGvFC4o-Ud5fJHdUmRCY"/>
