CN103699361A - Linux command execution method for Android platform - Google Patents

Abstract

The invention relates to a Linux command execution method for an Android platform. The Linux command execution method comprises the following steps of: (1) firstly, obtaining a command execution process through Runtime. getRuntime (); (2) obtaining input and output streams of the command execution process; (3) sending the command to the process through the output streams; (4) reading return results from the process through the input streams, wherein the process runs in a thread, and continuously reads the input streams. Through the method, the Linux command is input through Android on equipment conveniently, and results after the execution of a system are obtained. Without a PC and a data line, the whole process can be carried out entirely on a mobile phone, and the equipment can be operated anytime and anywhere.

Description

The Linux command execution of Android platform

Technical field

The Linux command executing method that the present invention relates to a kind of Android platform, is mainly used in mobile phone and panel computer.

Background technology

Android system is developed based on (SuSE) Linux OS, the kernel of android is exactly the kernel of the Linux that uses, so be the shell-command that can carry out Linux platform in android.Traditional method is to connect mobile phone or the dull and stereotyped PC of arriving by data line, then with the command-line tool ADB on PC, carrys out fill order, and this method restrictive condition is more, uses inconvenient.

Summary of the invention

The Linux command executing method that the object of this invention is to provide a kind of Android platform, to solve the use PC connection device that prior art exists and to use ADB to connect the problem of fill order inconvenience.

Technical scheme of the present invention is: a kind of Linux command executing method of Android platform, and step is as follows:

(1) first, by Runtime.getRuntime (), get the process of command execution;

(2) then obtain inlet flow and the output stream of process;

(3) by output stream, order is sent to process;

(4) by inlet flow, from process, read and return results, this process is carried out in thread, constantly reads inlet flow.

The invention has the beneficial effects as follows: by the present invention, can by the android on equipment, input Linux order easily, and get the result after system is carried out.No longer need the auxiliary of PC, no longer need data line, whole process can be carried out completely on mobile phone, whenever and wherever possible to operate, very convenient.

Embodiment

The Linux command executing method of a kind of Android platform of the present invention, step is as follows:

1. first, by Runtime.getRuntime () .exec (" ls "), get the process of command execution.This step is how to make Android system carry out the method for Linux order.

2. then obtain inlet flow and the output stream of process.This step be how input command to the method for system.

3. by output stream, order is sent to process.This step is how to obtain the method for the return data after command execution.

4. by inlet flow, from process, read and return results, this process is carried out in thread, constantly reads inlet flow.

Innovative point of the present invention is, the method of use Runtime.getRuntime () completes the input and output of the Linux order of Android platform, can be on android mobile device directly input operation order obtain rreturn value, no longer rely on PC and data line.

Claims (1)

1. a Linux command executing method for Android platform, step is as follows:

(1) first, by Runtime.getRuntime (), get the process of command execution;

(2) then obtain inlet flow and the output stream of process;

(3) by output stream, order is sent to process;

(4) by inlet flow, from process, read and return results, this process is carried out in thread, constantly reads inlet flow.
