1. Android ShellUtils手機管理器

??Android Shell工具類，可用于檢查系統root權限，并在shell或root用戶下執行shell命令。如：
checkRootPermission() 檢查root權限 。execCommand(String[] commands, boolean isRoot, boolean isNeedResultMsg) shell 環境執行命令，第二個參數表示是否root權限執行 execCommand(String command, boolean isRoot) shell環境執行命令。

1.1. 代碼

import java.io.BufferedReader;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InputStreamReader;
import java.util.List;public class ShellUtils {public static final String COMMAND_SU = "su";public static final String COMMAND_SH = "sh";public static final String COMMAND_EXIT = "exit\n";public static final String COMMAND_LINE_END = "\n";public ShellUtils() {}public static boolean checkRootPermission() {return execCommand("echo root", true, false).result == 0;}public static CommandResult execCommand(String command, boolean isRoot) {return execCommand(new String[]{command}, isRoot, true);}public static CommandResult execCommand(List<String> commands, boolean isRoot) {return execCommand(commands == null ? null : (String[])commands.toArray(new String[0]), isRoot, true);}public static CommandResult execCommand(String[] commands, boolean isRoot) {return execCommand(commands, isRoot, true);}public 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 : (String[])commands.toArray(new String[0]), isRoot, isNeedResultMsg);}public static CommandResult execCommand(String[] commands, boolean isRoot, boolean isNeedResultMsg) {int result = -1;if (commands != null && commands.length != 0) {Process process = null;BufferedReader successResult = null;BufferedReader errorResult = null;StringBuilder successMsg = null;StringBuilder errorMsg = null;DataOutputStream os = null;try {process = Runtime.getRuntime().exec(isRoot ? "su" : "sh");os = new DataOutputStream(process.getOutputStream());String[] var13 = commands;int var12 = commands.length;String s;for(int var11 = 0; var11 < var12; ++var11) {s = var13[var11];if (s != null) {os.write(s.getBytes());os.writeBytes("\n");os.flush();}}os.writeBytes("exit\n");os.flush();result = process.waitFor();if (isNeedResultMsg) {successMsg = new StringBuilder();errorMsg = new StringBuilder();successResult = new BufferedReader(new InputStreamReader(process.getInputStream()));errorResult = new BufferedReader(new InputStreamReader(process.getErrorStream()));while((s = successResult.readLine()) != null) {successMsg.append(s);}while((s = errorResult.readLine()) != null) {errorMsg.append(s);}}} catch (IOException var24) {var24.printStackTrace();} catch (Exception var25) {var25.printStackTrace();} finally {try {if (os != null) {os.close();}if (successResult != null) {successResult.close();}if (errorResult != null) {errorResult.close();}} catch (IOException var23) {var23.printStackTrace();}if (process != null) {process.destroy();}}return new CommandResult(result, successMsg == null ? null : successMsg.toString(), errorMsg == null ? null : errorMsg.toString());} else {return new CommandResult(result, (String)null, (String)null);}}public static class CommandResult {public int result;public String successMsg;public String errorMsg;public CommandResult(int result) {this.result = result;}public CommandResult(int result, String successMsg, String errorMsg) {this.result = result;this.successMsg = successMsg;this.errorMsg = errorMsg;}}
}

1.2. 使用

（1）關機

public void ShutDown(View view) {ShellUtils.execCommand("reboot -p", true);
}

（2）重啟

public void Reboot(View view) {ShellUtils.execCommand("reboot", true);
}

（3）快速重啟

public void FastReboot(View view) {ShellUtils.execCommand("busybox killall system_server", true);
}

（4）進入刷機模式

public void Recovery(View view) {ShellUtils.execCommand("reboot recovery", true);
}

（5）進入引導模式

public void FastBoot(View view) {ShellUtils.execCommand("reboot bootloader", true);
}
