How to run node.js application about dna2oslab HOT 3 CLOSED

@gikarasojo there are several ways to be able to run javascript app.

Method 1:
ref: https://github.com/dna2github/dna2mtgol/blob/master/fileShare

• Step 1. compile node js with the build script provided in this repo (or download from release page).
• Step 2. put compiled node js binary file to resource folder of your Android project.
• Step 3. in MainActivity.java of (ref), InputStream nginx = app.getResources().openRawResource(R.raw.nginx);; you can write code similarly to open a file in application data folder, read the stream and write to the file; grant executing permission to the file
• Step 4. similar to NginxServer.java of (ref), p = Runtime.getRuntime().exec(cmd); you can write some code to start a thread and set cmd for example /data/data/com.myapp.nodejs/binary_nodejs /sdcard/hello/index.js (i.e. class Server extends Thread { @override public void run() { String cmd = "/data/data/com.myapp.nodejs/binary_nodejs /sdcard/hello/index.js"; Process p = Runtime.getRuntime().exec(cmd); p.waitFor(); /* new Server().start() to kick off the background server and kill p when want to stop*/ } }, the difference between Nginx and NodeJS is that Nginx runs in daemon mode and NodeJS runs in foreground, if you directly run in the code without a thread, waitFor method will block your app until the NodeJS process is terminated.). Then p is a process of node js app. (if you run a js server, remember to declare permission statement in AndroidManifest.xml)

Method 2:
ref: https://github.com/shadowsocks/shadowsocks-android

• Step 1. read the configuration of src/main/jni/Android.mk in (ref); copy the build script provided in this repo into the file with Makefile style; config resource folder as build target
• Step 2-3. the same to Step 3-4 of Method 1

Method 3:

If you know some Linux system programming, you can also use mmap, load node js binary into memory and then run node js app, to save storage space.
