Android开发测试会经常遇到crash。

（1）cd /data/tombstones/

（2）adb pull /data/tombstones/tombston_00   (保存路径)

（3）打开tombstone文件，找到backtrace：

backtrace:

    #00 pc 000239c2  /data/app/com.morpho.cinemagraph-1/lib/arm/libmorpho_cinema_graph.so (mor_cinegrph_Renderer_Ycc420Semiplanar_draw+2377)
    #01 pc 00021871  /data/app/com.morpho.cinemagraph-1/lib/arm/libmorpho_cinema_graph.so (mor_cinegrph_Renderer_renderWithMvec8Real+260)

    #05 pc 00017f0d  /data/dalvik-cache/arm/data@app@com.morpho.cinemagraph-1@base.apk@classes.dex

（4）在终端，cd到库文件目录下：addr2line -e （库文件.so） 00015ab1  得到库文件JNI层出错地方
