Android :: Deploying Custom Configuration With Application
Aug 2, 2010
I have developed an App that talks to a set of web services. Because the App is used in different environments and for different purposes, I would like to provide a way to automatically deploy a configuration alongside the App that contains the settings for the environment (url of the locally hosted web services for example) and App settings (such as a timer period for talking to the web services). It would be tedious to have a UI for this and have to do it on every device post installation. Things I have tried and why they didn't meet my requirements:
*Raw Resource: If I unzip the apk and change the settings file, it becomes invalid as I need to resign the apk.
*Reading straight from the apk with ZipFile/ZipEntry: Device complains upon installation that the config file is not signed.
*PreferencesActivity: Requires device side UI; It would be tedious to have a UI for this and have to do it on every device post installation.

I have a simple Android application that loads a page in a WebView, then most of the real work is done by the server-side scripts. Everything is working great, except that I currently have the page URL hard-coded in the Android application, sort of like this:
mWebView.loadUrl("https://www.my-application-url.com");
This was fine until this morning when I was asked to to make it so that the user is prompted to enter the URL the first time the application run, and the URL that is entered by the user is then saved and used automatically by the application from that point onward. I was also asked to make it so that the user can change the URL if they choose to do so. The reason I was asked to do this is so that users can install the server side of the application on their own servers and my Android application will be able to connect without me having to write a custom version for each user, with their URL hard-coded into the application.
I am unsure what is the best way to handle this in Android. It seems that I probably need to add some type of configuration interface to the application that is shown by default on the first run, then only when the Menu button is pressed on the following runs. From this configuration interface I guess I would then get the URL from the user and serialize it for future use. What is the best way to accomplish this?

I am still learning bu find Android the cool platform for allot of useful applications. I have written a Service for doing GPS tracking and it consists of a Service and a Control activity to manage, monitor and configure the service. I am looking for the preferred way for the Control Activity to define settings for the Service, things like IP address and Update interval. I envision something like a Registry on windows where these settings can be shares and updated.

Where should I store my Android application's configuration settings? Coming from the .NET world I was expecting something like .config. Do I create a file under res/values, and use that?

We are investigating the possibilities to package & deploy platform UI extensions which can contain both Java code and resources - which then can be (re-)used by applications using <uses-library> tag in the AndroidManifest.xml. One solution which has been discussed was to use the aapt -x option together with the new --custom-package option introduced in November to generate unique resource identifiers for the shared resource package. Then, just as the <uses-library> information in the manifest file would bootstrap the class loader with the listed extension packages, it would add these packages to the asset manager as well - allowing the asset manager to locate and load the extension resources. (This would require a platform extension.)If this is a way forward - using the 8 package bits in the resource identifiers? This solution would probably work initially for one vendor since the allocation of unique package identifiers would be an internal issue, but if extension packages where to be exchanged within the android community there would be a high risk of packages using the same identifiers.

I have to make other developers to be able to connect to my service, but my AIDL imports my classes. I don't want to give them the source code of the service, just the APK and some kind of a stub file (java, jar?). How can I give them something - "the glue" - which makes them to use the classes in my AIDL and using the service akp without getting the sources of the service?

I am looking for an application that can create a map by me carrying the phone and walking a certain path.There is a 300 acre park near where I live. The maps they provide are way off base. I would like to walk all of the trails and have the Droid record where I am walking.You know, this may be easier than I think using ASE and writing a Python script. I'll just get the location every half second and write it out to a file. It'll be interesting to see how the maps turn out, seeing the low resolution of the GPS receiver.

I've started to develop in Android 2 weeks ago and until now, I like it! Currently I am working on a project where I have to display an individual map (not a google maps view, I'd like to display the map of a building's interior) with which the user can interact(mark positions, etc.).
Is there a framework or an existing app that I could use? Of course I searched the internet but could not find anything. Perhaps it is in some way possible to use the google maps API?

I currently have an app that has many activities and needs to have a way of maintaining state between these activities.
I use the Application class to do this, declaring my global variables and using getters and setters to interact with my activities.
I was hoping to place a few custom methods in there, so that when I want to do a common task like, for instance, display an error message, I can declare the method in my application class and call it from any activity that uses it
EscarApplication application = (EscarApplication) this.getApplication();
EscarApplication being the name of my application class above.
I have tried to include this method in my application class:
CODE:.....
In the hope that I can call this method from activity without having to redeclare it, but when I call it using something like below I get an null pointer exception:
Visit.this.application.showError("Update error", "An error has occurred while trying to communicate with the server");
Visit being the name of my current activity above.
Should this work, or can I only use getters and setters to change global vars in an Application Class.
EDIT Stack Trace:
CODE:...............
The dialog is declared as such in the application class:AlertDialog alertDialog;
Created in that same class:alertDialog = new AlertDialog.Builder(this).create();
And the method to call it in that class is as follows:
CODE:.............
And finally, it is called from an activity like so:
CODE:........................

I created a test android app that does two simple things, open the browswer and open the calculator
My main problem is that once I put a custom permission inside the mainfest, I can no longer open my own application. The app does appear on the launcher screen but when I launch it, it will say "App isn't installed". However using a second app and giving it the proper uses and making sure it's signed by the same signature it opens fine.Here is the manifest for my main app:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.dms_test_app2"[code].....

I have two published apps that are pretty targeted to the user collecting their personal medical data (like Blood Pressure, etc.) and then, eventually sending it somewhere, if they choose.
I decided to put Read/Write permission on my ContentProvider, so if another app comes along that wants to the access that content, the user will be warned. The permission that is required is declared in my apps.
When the user installs my apps, they are also given a warning that the app requires that permission (even though it's the one that declares it), and it shows up in the Marketplace also.
The question is: Is it possible that the permission acceptance part of installing my app could be putting customers off? I don't know what other's acceptance rate is, but mine is around 50% of customers who download it have active installs.

I would like to know if the Android handsets can be configured Over-The-Air; in other words, if they can be configured for settings (such as GPRS , WAP or MMS ...) using OTA. If yes, do they support OMA CP provisioning? Is there an XML example that can be used to configure the Android devices?

I recently decided to remake my UI, I had text built into my ImageViews which I was advised against, so I have now gone with TextViews, however I would like to carry on using the Roboto font. Is it possible to do so?
I have already added "Roboto-Light" to the assets/fonts folder but I'm looking for an easy way to implement it since I want some TextViews to have the font and some to be standard.
Is there a way I can do it in the XML? So I can select individual TextViews rather than the entire application?

I've only owned an Android for 6 days (Samsung Galaxy S i9000) and one of the first things I installed was Juice Defender, having used iPod Touch extensively, I know how heavy on battery things like WiFi can be. Anyway, JD makes the phone really really leggy. It can take a minute sometimes (literally, 45-65 seconds) for the JD screen to come up when launched. Similarly when waking from sleep it takes ages for the data connections to become active again. Have I misconfigured JD? Is it really this slow and creates this much lag? Does it just not like the (fairly new) i9000? I've just uninstalled it there right now (left Ultimate Juice on) and the phone is much snappier. It's like using it for the first time. Which, considering JD was installed in the first half hour of my owning the phone, it kind of is. What I really wanted was the WiFi on/off according to cell tower location data so I can have it go on and off when I leave the house. Guess it's no real biggie. Having limited background data (e.g. the 2 mins per 15) is handy too. Are there any other apps which have JD functions - even if more limited in scope - that I can try?

I recently installed a custom ROM in my phone.
What I noticed is that the problem is either that my phone drivers can't be installed for some reason (I have a SGS being treated as a Google Nexus S), or I just can't implement applications.I mean that when I try to build an application on Eclipse, my phone is not recognized, like I don't have it plugged in.

How can I detect if the G1 keyboard is hidden or open at application startup? My app always runs in landscape mode, but I can only find how to detect keyboard configuration *changes* (through onConfigurationChanged()). So how can I retrieve the current keyboard configuration (open or closed) at application startup?
