3，log分析
(1)首先報錯的so是 /system/lib/libdvm.so /system/lib/libandroid_runtime.so /system/lib/libc.so 等系統級的so，所以是使用系統的某個類或者是api造成的crash
(2)然後其中 關鍵字
fault addr deadbaad 野指針了
dvmHeapBitmapSweepWalk bitmap使用除了問題
dvmCollectGarbageInternal GC回收相關
總結一下：在使用Bitmap的時候，某個操作觸發了GC，然後引發了野指針
所以重點尋找Bitmap使用的流程是否正確，有沒有使用被釋放之後的bitmap
