我正在创建一个包含登录的Android应用程序，登录页面后，我已经访问了Google地图。当我尝试在没有登录地图的情况下首先运行谷歌地图时，它工作正常，但当我在其中引入登录页面时出现错误＆＃34;不幸的是，应用程序停止了＃34;
继承我的Main_activity.java

public class MainActivity extends ActionBarActivity {

setContentView(R.layout.login);
chkcmd = (Button) findViewById(R.id.bLOGIN);

}
@Override

以下是我的应用的代码。任何帮助都将深表感谢。谢谢
答案 0 :(得分：1)
下面：
Intent openStartingPoint = new Intent("com.example.goon.Maps");
您可能会收到以下错误：
ActivityNotFoundException：找不到处理Intent的活动
因为AndroidManifest.xml com.example.goon.Maps行动中没有可用的操作。
将Maps活动操作更改为com.example.goon.Maps：
<intent-filter>
<action android:name="com.example.goon.Maps" />
</intent-filter>
现在使用com.example.goon.Maps操作启动Maps活动。
或
您还可以使用班级名称
启动Maps活动
Intent intent=new Intent(v.getContext(),Maps.class);
v.getContext().startActivity(intent);
