Question

我有问题，因为我正在按照本教程https://www.youtube.com/watch?v=vQ__ECAEAS0，如何在android项目中实现Google maps v2，我在新活动中完全喜欢教程，然后我尝试打开新活动，应用程序是每次都崩溃：抱歉新手知道...

创建新活动：

public void openMap(View view) {
        Intent intent = new Intent(this, MapMain.class);
        startActivity(intent);
    }

XML：

<Button
        android:id="@+id/bMapas"
        android:layout_width="150dp"
        android:layout_height="150dp"
        android:layout_above="@+id/buttonSettings"
        android:layout_toLeftOf="@+id/textpowererdBy"
        android:background="@drawable/st_nohow_b"
        android:onClick="openMap"
        android:text="@string/map" />

Answer 1

我注意到的一件事是你没有把这部分放在你的清单文件中：

<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />

如果没有此清单文件中的Google Maps API V2部分，

meta-data将无法运行。

如果在进行此更改后仍无法正常工作，请尝试查看我就此主题撰写的博文：

Google Maps API V2 Guide

您也可以查看本教程，确保获得密钥并以正确的方式设置API控制台：

Google地图v2未在新活动中显示
