DeviceImageZipFlashingTargetPreparer
public
class
DeviceImageZipFlashingTargetPreparer
extends DeviceUpdateTargetPreparer
一种目标准备器，用于使用通过特定格式提供的设备映像刷写设备。
设备映像格式的概要要求：
- 设备映像文件必须为 zip 文件
- zip 文件的根目录中必须包含 flash-all.sh 脚本
- 脚本必须假定设备位于对
adb devices 可见的用户空间
- zip 文件的其余部分将解压缩到与脚本相同的位置，并采用相同的目录布局，脚本可以通过相对路径引用 zip 中打包的任何文件
- 刷写后，脚本必须将设备恢复为相同的状态
- 环境变量
ANDROID_SERIAL 将作为执行环境的一部分设置为设备序列号
- 该脚本可能会假定它在 PATH 上有
adb 和 fastboot
此目标准备程序将在上述要求中概述的假设下解压缩设备映像 ZIP 文件并执行封闭的
flash-
all.sh。

format.\n\nHigh level requirements for the device image format:\n\n- Device image file must be a zip file\n- The zip file must include a flash-all.sh script at the root\n- The script must assume that the device is in userspace visible to `adb devices`\n- The rest of the zip file will be extracted into the same location as script with the same directory layout, and the script may make reference to any files packaged in the zip via relative path\n- After flashing, the script must return the device to the same state\n- An environment variable `ANDROID_SERIAL` will be set to device serial number as part of the execution environment\n- The script may assume that it has `adb` and `fastboot` on PATH\n\nThis target preparer will unpack the device image zip file and execute the enclosed `flash-\nall.sh` under the assumptions outline in requirements above.\n\n\u003cbr /\u003e\n\nSummary\n-------\n\n| ### Public constructors
