最近同事升級了新版SDK后扼褪，發(fā)現(xiàn)布局文件無法預(yù)覽了，拋出異常：

但是APP運行正常粱栖，僅僅是無法預(yù)覽布局话浇。

我又重現(xiàn)了下，確實如同事所說闹究，只要布局里包含了這個RtcView幔崖，就無法預(yù)覽：

看了下報錯堆棧，是RtcView執(zhí)行onAttachedToWindow時有個初始化操作涉及到了native方法渣淤，需要加載so庫赏寇。正常運行APP的話，加載so庫的操作都是一開始就執(zhí)行完了价认，所以不會有類似問題嗅定。AndroidStudio預(yù)覽布局文件，居然也會執(zhí)行到View的onAttachedToWindow方法用踩，真是又開眼了渠退。有空一定要了解下AndroidStudio預(yù)覽布局文件的原理。

解決方法就是在RtcView報錯的地方加try catch捕獲異常脐彩。不知道是否還有更優(yōu)雅的方案碎乃。
