基本信息：

SDK 使用5.16.1 版本

问题描述：

使用matter 需要在有matter设备的家庭中进行初始化，偶尔会到一些 so库的闪退问题，解决起来颇为头疼，最终遇到的情况和解决的办法如下。

matter的初始化的代码如下

IThingMatterFabricManager fabricManager = ThingHomeSdk.getFabricManager();
fabricManager.initFabric(getContext(), spaceId, new IThingDataCallback<OpenFabricInfo>() {
     @Override
     public void onSuccess(OpenFabricInfo result) {

}

@Override
public void onError(String errorCode, String errorMessage) {

}
});

这里的闪退原因初始化initFabric 重复的init了，在initfabrci初始化的时候，是一个异步的行为，需要等待initFabric 完成后才能进行下一个initfabric

表现的情况为有常规初始化，却闪退，通过日志分析，在初始化的时候有报错 src/credentials/FabricTable.cpp:795: CHIP Error 0x0000000B: No memory。针对这情况，分析matter源码找到原因，因为内部限制了 fabric初始化，最多只能为17，所以进行初始化 initfabric 的时候也需要考虑数量问题。避免越界导致的无法创建，进而引起后续的崩溃
