adb shell so

在adb shell中调用so库，需要使用命令`dalvikvm`，具体步骤如下：

1. 确认设备已连接到计算机，并打开设备的开发者选项和USB调试功能。

2. 在计算机上安装adb工具，确保adb工具已经在环境变量中配置。

3. 将so文件推送到Android设备上。可以使用以下adb命令将文件推送到设备上：`adb push <local_file_path> <device_file_path>`

4. 使用adb shell命令进入设备的shell环境。

5. 运行以下命令来加载so文件：`dalvikvm -cp <jar_file_path> <java_class_name>`

其中，`jar_file_path`是包含使用so库的java程序所在的jar包路径，`java_class_name`是包含使用so库的java程序的类名。

6. 如果so库需要传递参数，可以使用以下命令：`dalvikvm -cp <jar_file_path> <java_class_name> <parameter>`

其中，`parameter`是传递给java程序的参数。

注意，由于不同的so库可能需要不同的参数和调用方式，以上命令可能需要进行适当的修改才能正常使用。

adb shell find / -name "gadget-android-*.so" 2>/dev/null系统找不到指定的路径。

如果在执行 `adb shell find / -name "gadget-android-*.so" 2>/dev/null` 命令时提示系统找不到指定的路径，可能是因为没有正确的权限或者没有安装 frida-server。

请确保你已经正确地安装了 frida-server，并使用 root 权限执行该命令。如果你的设备没有 root 权限，可以尝试使用 `adb shell su -c 'find / -name "gadget-android-*.so" 2>/dev/null'` 命令以 root 权限执行该命令。如果你的设备已经 root，但仍无法找到 Gadget 库路径，请尝试手动查找该库所在的路径并手动指定路径启动 frida。

for /l %%i in (1,1,1000) do ( @echo ********************* the %%i times********************** @ adb shell reboot @ ping -n 60 127.0.0.1 >nul ) 代码详解

The code you provided is a batch script that includes a loop. It executes a series of commands for each iteration of the loop. Let's break down the code:

for /l %%i in (1,1,1000) do (
    @echo ********************* the %%i times**********************
    @ adb shell reboot
    @ ping -n 60 127.0.0.1 >nul
)

This code uses a `for /l` loop, which iterates from 1 to 1000 with a step size of 1 (`(1,1,1000)`). For each iteration, the commands within the `do` block are executed.

Inside the loop:

1. `@echo ********************* the %%i times**********************` prints a line that includes the value of `%%i`, where `%%i` represents the current iteration number. The double percent signs (`%%`) are used to escape the single percent sign and represent the variable `%%i`.

2. `@ adb shell reboot` executes the command `adb shell reboot` in the command prompt. This command is typically used to reboot an Android device connected to the computer via ADB (Android Debug Bridge).

3. `@ ping -n 60 127.0.0.1 >nul` pings the loopback address (`127.0.0.1`) 60 times (`-n 60`). The output of the ping command is redirected to the null device (`>nul`), effectively discarding the output.

This code seems to be intended for automating a sequence of tasks that involve rebooting an Android device connected via ADB and waiting for a specific period (60 seconds) between iterations.

Please note that running ADB commands or pinging in a loop can have implications, so make sure to use the script responsibly and in accordance with your specific requirements.
