记录一份Android shell工具类
代码
public class ShellUtils { private static final String COMMAND_SU = "su"; // 获取root权限的命令 private static final String COMMAND_SH = "sh"; // 执行sh文件的命令 private static final String COMMAND_EXIT = "exit\n"; // 退出的命令 private static final String COMMAND_LINE_END = "\n"; // 执行命令必须加在末尾 private ShellUtils() { throw new AssertionError(); } //检测root状态 public static boolean checkRootPermission() { return execCommand("echo root", true, false).result == 0; } //执行单行命令,实际还是调用的执行多行 ,传入命令和是否需要root public static CommandResult execCommand(String command, boolean isRoot) { return execCommand(new String[]{command}, isRoot, true); } //执行List<String>中的命令 , 传入List和是否需要root public static CommandResult execCommand(List<String> commands, boolean isRoot) { return execCommand(commands == null ? null : commands.toArray(new String[]{}), isRoot, true); } //执行多行命令 public static CommandResult execCommand(String[] commands, boolean isRoot) { return execCommand(commands, isRoot, true); } private static CommandResult execCommand(String command, boolean isRoot, boolean isNeedResultMsg) { return execCommand(new String[]{command}, isRoot, isNeedResultMsg); } public static CommandResult execCommand(List<String> commands, boolean isRoot, boolean isNeedResultMsg) { return execCommand(commands == null ? null : commands.toArray(new String[]{}), isRoot, isNeedResultMsg); } //执行命令,获得返回的信息 private static CommandResult execCommand(String[] commands, boolean isRoot, boolean isNeedResultMsg) { int result = -1; if (commands == null || commands.length == 0) { return new CommandResult(result, null, null); } Process process = null; BufferedReader successResult = null; BufferedReader errorResult = null; StringBuilder successMsg = null; StringBuilder errorMsg = null; DataOutputStream os = null; try { process = Runtime.getRuntime().exec(isRoot ?
