Question

使用产品：SuperMap iMobile 10i(2021) SP1 for Android
问题详细描述：用Fragment在AR管线与AR测量切换时，程序退出
问题重现步骤： 

if ("scene".equals(type)){
    FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();

    if (sceneFragment == null) {
        sceneFragment = new SceneFragment();

    }
    fragmentTransaction.add(R.id.content_framelayout, sceneFragment, "sceneFragment");

    hideAllFragment(fragmentTransaction);
    fragmentTransaction
            .show(sceneFragment)
            .commit();

}else if ("cartograph".equals(type)){
    FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction();
    if (cartographFragment == null) {
        cartographFragment = new CartographFragment();

    }
    fragmentTransaction.add(R.id.content_framelayout, cartographFragment, "cartographFragment");
    hideAllFragment(fragmentTransaction);
    fragmentTransaction
            .show(cartographFragment)
            .commit();
}

您好，您这个问题应该是属于fragment跳转的问题，可以看一下fragment是否被销毁。网上也有很多fragment跳转问题的解答，您可以参考一下这个地址：java - Android中使用FragmentTransaction对象的add方法后应用闪退 - SegmentFault 思否

不是fragment跳转问题，我把(SceneControl,ARCartographView)2个ar控件放一起，就直接崩溃

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    tools:context=".MainActivity">

    <com.supermap.realspace.SceneControl
        android:id="@+id/sceneControl"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />
    <com.supermap.ar.arcartograph.ARCartographView
        android:id="@+id/ar_cartograph_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

ARCartographView实例不应该和SceneControl实例同时生存，您那边如果要切换，建议把上一个活动销毁再启动下一个活动哈
