Android设备执行Linux命令语句

用于Android设备执行Linux命令语句，更改root权限等

import java.io.*;
public static boolean RootCommand(String command){
	Process process = null;
	DataOutputStream os = null;
	try{
		process = Runtime.getRuntime().exec("su");
		os = new DataOutputStream(process.getOutputStream());
		os.writeBytes(command + "\n");
		os.writeBytes("exit\n");
		os.flush();
		process.waitFor();
	}catch(Exception e){
		Log.d("*** DEBUG ***", "ROOT REE" + e.getMessage());
		return false;
	}finally{
		try{
			if(os != null){
				os.close();
			}
			process.destroy();
		}catch(Exception e){
		}
	}
	Log.d("*** DEBUG ***", "ROOT SUC");
	return true;
}

调用示例：

	//String apkRoot = "chmod 777" + getPackageCodePath();//获取整个apk权限

	String apkChmod = "chmod 777 "+"/dev/video0";
	RootCommand(apkChmod);
