E//system/bin/tombstoned: Tombstone written to: /data/tombstones/tombstone_00

在上述崩潰信息的最后給出了提示 “Tombstone written to: /data/tombstones/tombstone_00” , 崩潰日志信息被保存到了 /data/tombstones/tombstone_00 文件中 ;

二、手機(jī)命令行操作

---

進(jìn)入手機(jī)的命令行 ;

adb shell

獲取 root 權(quán)限 ;

su

進(jìn)入 /data/tombstones/ 目錄 ;

cd /data/tombstones/

查看該目錄下的崩潰日志文件 ;

ls

下面的截圖中可以看到 , 上述崩潰日志 tombstone_00 ;

首先將該日志文件拷貝到 /sdcard/ 目錄 ;

cp /data/tombstones/tombstone_00 /sdcard/tombstone_00

手機(jī)命令行操作完畢 , 執(zhí)行兩次 exit , 第一次退出 root 模式 , 第二次退出手機(jī)命令行 ;

exit exit

三、電腦命令行操作

---

之前在手機(jī)命令行中 , 我們將 /data/tombstones/tombstone_00 的崩潰日志文件拷貝到了 sd 卡中 , /sdcard/tombstone_00 ;

adb pull 命令無法從 /data/ 目錄中直接拉取文件 , 拷貝到 sd 卡中 , 就可以從 sd 卡拉取該文件 ;

將 /sdcard/tombstone_00 崩潰日志文件拉取到本地 ;

adb pull /sdcard/tombstone_00 .

這樣就獲取到了 tombstone_00 文件 ;

四、Tombstone 內(nèi)容

打開后查看其中的大致內(nèi)容 :
