I am new user in the area of Android, but have Linux knoweldge. I am trying to configure my android device LG Nexus 4 to act as Document Camera
For this purpose, I have to scp the files and then remove the files remotely. I have installed SSH server and my scp works, but my remote execution of commands using ssh not working, it throws error
with -v ssh gives the following messages
"Authenticated to 192.168.21.233 ([192.168.21.233]:57388).
debug1: channel 0: new [client-session]
debug1: Entering interactive session.
debug1: Sending environment.

debug1: Sending command: rm -rf /storage/emulated/0/DCIM/Camera/IMG_20130822_111706.jpg
exec request failed on channel 0 "
when I goggled it says that editing ssh_config file and uncomment: 'AddressFamily all' and changing it to 'AddressFamily inet' will work I checked in the android devices /etc directory, I did not find the ssh_config

What I am trying to do is get either nest-api in PHP or pynest in python to run out of SL4A in order to control my Nest thermostat ultimately out of Tasker. Both are found on github, but I can't link to them as I apparently need ten posts to do so. So a google search for "nest-api github" and "pynest github" will have to do I suppose.
I have absolutely no issues getting either to run out of Terminal on my MacBook Air, but for whatever reading the SL4A shell seems to escape my understanding. I would rather have the PHP script work, as it has more options for things I can set, which I like. Where to put the nest.class.php on my phone in order for the PHP shell to reference it when running the example.php or any script I write myself. When I put both files in the sdcard/sl4a/scripts folder and try to run either from within either sl4a or sl4a's shell I get a call to undefined function error.
For the python script, I'm not sure how I need to import the module so that I can call it with nest.py at the beginning of my command line prompt and follow it up with the user name and password and so on. I've done everything including trying to create an .egg file, which I've since been told is not necessary, and that I simply have to put it in the /sl4a/scripts folder. That doesn't make sense to me though, as I needed to run the setup.py command on my computer in order to start using it, and the .egg file should be the equivalent of that on the phone, no?
So what I am looking for is the foolproof way to get either a php or python script running through the shell that isn't actually hooking into the Android environment at all, which is what all the writeups I have found in my searching seems to pertain to. Then eventually make sure that they are available in a way that Tasker can call them. I should also note that all this has been done in an emulator through eclipse until this point, as I didn't want to go screwing around with my brand new Nexus 4's file structure until I had the best practice perfected.

I would like to know how to execute code before exiting application. My application is composed of several activities. When the user starts the application (from the launcher menu or from a notification in the status bar), he goes in an InitActivity where I process some initializations. From user experience, application always restarts. One of these initializations is to init a network manager and start a thread that periodically sends a network request to notify a server that application is active.
I need to process some end operations, like stopping this thread when user quits application, for example by pressing the HOME key or BACK key when he's in the root activity. However, when the user press the HOME key, application is still running in background.
Q1 : is it possible to execute code when exiting application (I see the onTerminate() method of the class Application but it seems not to be always called)?
Q2 : Is it possible to force application exit (activity method finish () only destroy the current activity, not the application)?
Q3 : Is it possible to handle HOME key press (onKeyDown() is not called when this button is pushed)?

Test run failed: Permission Denial:

because package com.jayway.test does

How can I compile my application with system permissions?

I have a Motorola bluetooth headset and with my old Storm I could push the button on the headset and it would say "Say a command" from here I could say "Call John Doe mobile" and it would call him up. Haven't figured out how to make this work on the Droid in the same manner natively. Is it possible or is there an application. Purpose of bluetooth is to be hands free. Its not very hands free if I have to pull my phone out my pocket to dial the number first to be able to use the headset.

Does anyone know if there is an application that will send command lines to a PC? I would like to use this to either both launch programs and send other commands (such as changing the audio output on my PC). I am able to do this by creating shortcuts to the commands, then using a remote program (like premotedroid) to control the mouse and click the shortcuts, but it would be really cool if the phone could just send the command directly to the PC.

I'm configuring emacs to debug android apps. My problem is since I'm attaching jdb to DDMS I cannot set proper classpath (jdb just won't start when I try to set -classpath and -attach together). So jdb is practically blind - no entry point for class, no interactive debugging. How can I specify classpath when attaching debugger to ddms?

I use navigation on my motorcycle and I used to be able to use Pandora at the same time, but lately just keeps stalling. Some seem to think in 2.1 Android's memory management is somehow messing with services that Pandora needs to run. Would installing it as a system app help in any way? I am running Cyanogen 5.0.5.7 if it matters at all.

I'm a big fan of Toggle Settings but my one wish would be that it could toggle GPS. From what I understand, the security of Android doesn't allow any app to turn GPS on/off. My question is, since installing Mobile Defense as a system application allows it to turn my GPS on, would installing Toggle Settings as a system app enable the same feature? Does anybody know of a way around this or another app that is similar and can toggle GPS settings?

I use system panel light to check what is running in my background, just to have an idea. My question is, what is a cached application (inactive)? I am wondering, because I am trying to optimize my battery life and I want to know how this phone works with things running in the background. Should I end those applications that are cached, or are the really not doing anything sitting there?

I always had windows mobile devices in the past, and like you must know, the old good windows mobile no longer exist... Microsoft killed it.
So I switched to Android. I really like android, The way it works is pretty the same than windows mobile with file browser, files system(Not like the Iphone without any way to deal with a file at all), .APK install like the .CAB on WM...
One think that I loved on WM is how easy it was to make shortcut by yourself, even with parameters. As example, it was easy to create a shortcut to Coreplayer to play an HTTP stream when simply clicking on it.
Like: "coreplayer.exe my_teststreamDOTcom : portNumber"

Just getting started here. Working on an Android application, which needs to execute a google web search from within a ListView activity and display the results in that List View.
Such search would always be for the same "static" subject, such as "bowling alleys in Chicago...", so, the user will not be entering any search criteria. What is the proper way to accomplish this, please?

I have a rooted samsung captivate with sideloading enabled. After experimenting with different wifi tethering apps from the unofficial market, I began experiencing difficulties with my wifi connection. Even after uninstalling every app that I thought was changing the wifi state, the problem still persists. I can turn on the wifi and it will act normally for about 30 seconds before turning off without user intervention. In dmesg, the error is as follows: 'mmc1: Got command interrupt 0x00060001 even though no command operation was in progress.' Is this caused by an app or is this a more complicated problem?
