我创建了一个具有 LoginActivity 的应用程序（使用具有恒定凭据的登录表单） TestmapActivity（使用 Google Map Api - 显示地图）

布局：登录（LoginActivity）

myMap (TestmapActivity)

Intent dashboard = new Intent(LoginActivity.this, TestmapActivity.class);

                        // Close all views before launching Dashboard
                        dashboard.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
                        startActivity(dashboard);

我用google Api 2.3编译了上面的项目

成功安装，但登录成功时出现错误：应用程序意外停止
