使另一个文件夹/文件可读写的命令（Shell Script Android）

挂载/system ReWritable：

mount -o rw,remount,rw /system

和ReadOnly：

mount -o ro,remount,ro /system

您也可以将其用于其他目录。

PS：这些命令用于linux terminal。

这是在android上执行此代码的示例代码：

//your command
String[] commandrw = {"mount -o rw,remount,rw /system"};

//cmds = your command;
public boolean RunAsRoot(String[] cmds){

    Runtime runtime = Runtime.getRuntime();
    Process process;
    try {
        for (String cmd : cmds) {
            process = runtime.exec(new String[] {"su", "-c", cmd});
            if (process.waitFor() != 0) {
                // Command failed
                return false;
            }
        }
    } catch (Exception e) {
        return false;
    }
    return true;
}

//put this code in a buttonclick or oncreate etc...
RunAsRoot(commandrw); //replace commandrw with your command
