Working JAVA emulator? - Galaxy S 4 Active Q&A, Help & Troubleshooting

Anyone found a JAVA emulator that actually works for the Galaxy S4 Active?
I've tried JBED and a few others, followed all directions with moving files as root and rebooting and whatnot. The app(s) open but hang up and say they have quit unexpectedly after a while.

Apps That Run In Background

I have tons of apps, but none should be running in background except a few,
Right now Bar control and Sim checker should be only ones running in background. But yet the phone is acting so slow, So I wonder if there's more apps running in background I cant see or something that slowing down the phone
So can someone post the name of any app that can see EVERY SINGLE thing running in background but easily enough someone noob as me at this phone can understand, I had one but was all codes and I could not make heads or tails, I just want to know whats running thats making it act so damn slow
second, does sim checker or bar control take up lot of cpu or memory? or anything? if they do, or does anyone know any other apps that take up a lot of resources from the system so I know to get rid of them or prevent me downloading them in the future
If you install Terminal Emulator you can run the linux command top to get a realtime list of running processes and their cpu usage.
Hi, I'm the dev of SIM Checker. Actually it just checks at boot if the sim card is the correct one, and if so it stops itself. So it's not using any cpu and the garbage collector will kill it when there's need of memory - if you want you can manually kill it.
Well thats good to hear...Sim checker is great app, ok so I did the command in the terminal but wont let me scroll up so I cant see everything
do it on the pc through adb shell
i just uninstalled
wertago phonebook and quickoffice.
they all ran in the background right from the startup which is gay. i would have kept them if they wouldn't restart them self after a reboot or after i close them trhough task manager
How do I run it from adb shell in my pc?
Also ya the advance task manager I have I close everything before I do anything else and the services have no apps running I downloaded so why is it so slow? is there something besides a service that can run in background from an app? even with that "top" command in terminal everything besides like 2 system things are 0% cpu..but does not show memory usage

[Q] Java Midlets on 2.1

Right, got myself a galaxy, brilliant phone, battery life still appaling (just switched off of HTC Touch Pro ).
Now i dont have any illusions on running wm6 apps on android, but i'm pretty sure something can be done about j2me.
I have loads of games from my motorola razor times and would like to revisit them. Particularly DoomRPG and that other game with elves and orcs...
Tl;dr: Any way to run j2me stuff on android 2.1?
Yes, you actually can. There's a wrapper for JAVA applications. Not all of them work, but most games do.
It even has a virtual "keypad", but it's kinda buggy and you have to mess around in the options for it. There's multiple virtual controller options and some work better than others.
AFAIK, it's not available on the market, but you can download it from the official site: http://www.netmite.com/
How do you install your own midlets onto SGS ? the app only lets me dl it off the net... or is it just me ?
While it seems that the APP only allows you to play with games on their list, that's not the case.
I personally upload the .JAR to a website I own and then I select them browsing the internet on my phone. It downloads the game and installs automatically (like a regular .apk).
I don't know if you can just copy the .jar to the phone memory and run it from there. I believe you have to download from the Internet, as selecting it from a file browser simply says that there's nothing to open that filetype. When downloading from a homepage, the browser opens up the application and it auto-installs to you.

Always Keep Application Running

Friends,
I would like to figure out how to keep an application always running in the background, regardless of the memory situation on the device. The application I never want to close in the background is the Terminal Emulator (the Linux command prompt).
Does anyone have any thoughts on how to keep an application from closing in the background? Thank you!

Just dont close the app with the backbutton. Just leave the app as it is. It will always be running in the background. By holding the 'home-button' you can quicly acces the terminal again. The taskmanager will pop-up
Unfortunately not closing the app only works in the short term, meaning that once memory usage gets high enough Android will start closing background tasks on its on. This is what I would like to avoid.
For background information, I do have root on by Tab.

What do you want to keep running? Give a hint please
The application I would like to keep running in the background at all times is the Terminal Emulator (the paid version which is called Better Terminal Emulator).
Any thoughts are welcome.
UPDATE
This has been addressed in the latest version of Better Terminal Emulator... this app now runs as a service, and does not quit unless you specifically ask it to quit, making the Tab most like a true linux box. This is wonderful news!
Not to take over this thread, but how do you STOP from some applications from running in the background.
I always have ebook and google maps running in the background and cant stop them from running in the background.
any help?
Push and hold the home button, then choose task manager, then on the running applications tab, tap exit all.
There are apps in the market, called task killers, that close a program when you exit it. The upside is free memory, the downside is it eats some battery time (i don't know why).
It's ok to start a new thread, especially if your question is away from the title. Your question would have been a perfect new thread.
Hi guys, did someone find a solution for this? I have a linux loopfile running on my device, but I can't keep my session (on linux) open because android closes terminal emulator each time I open vnc for acces my linux.
Please if anyone find a solution mp me.
(excuse my english, I'm argentinian)

and search for the app and turn the setting switch on and enable (Stay resident in memory) and force show in recants max notification priority and force ongoing notifications
Add this to your build.prop sys.keep_app_1=(app package name here)

[Q] Java problems

One thing that happened when I first rooted my 7100 was that the stock browser kept crasching. So I installed the dolphin which was fast and worked pretty good. However one thing that I thought was the browser seems to have something to do with java. Some sites keep crashing now on both browser, however stock keeps crashing the most.
Is there something to do (except turn of java script) here?
