Hi, I am just starting developing and I have been playing with the notepad sample code on android developers (the ones you get with the SDK). I have added it to the bare-bones of my app, and the first Activity opens fine and the menu works, but when the first activity opens, the debugger gives me the error
Code:
Failed to find provider info for com.example.notepad.provider.notepad
I changed all the references to com.example... to my package name that I could find, but none of them referred to the "provider"
The debugger also says that the activity is starting but I get an Activity not found exception.
It is looking for dat=content://com.example.notepad.prover.notepad/notes
I have tried to search for this reference in all the files, but I am not seeing it (or rather the search and find parts of Eclipse are not finding it.
What am I missing?
Sorry, I can do Java Applets, but this Android thing is completely new!

I hope this isn't a stupid question. But I couldn't find any real info regarding this. And after reading the Mysteries of Science thread it seemed to me, there really isn't much information regarding such things. So:
I noticed that for almost all Linux based OS you can find in-depth descriptions on how the OS works on a basic level. For example where specific settings are stored.
The guides at android.com deal with app development, but don't specify how you use the OS as a root user. For example, if I want to change WLAN settings, there must be a way to do that without using the GUI or by using special classes but by editing a config file. Or where does Android store the startup settings, i.e. which apps to start at boot time or at specific system events. Or where do apps register as default app for viewing certain filetypes. There is a description how to code it, but not how Android stores that information and how it can be edited/viewed manually.
Since it's linux based I guess there are plain text config files for all those things. But where...? Was such information ever released by Google?

You can change network interface with 'ifconfig' command.
You can get ifconfig command by installing busybox.
There are commands that can be used, but this is still a bit liek try&error. So it seems there is no full documentation on how Android works?
Has Google ever addressed this, do they plan to release such documentation?
This is probably a noob question, but how can you view the coding of an android application? I just had a small test app developed for me and I would like to look at the "guts" of it.
I downloaded the emulator but I haven't been able to figure out how to see my app's code using it. Maybe there is another way that's easier? You know, something akin to the "view page source" tab enabled in many browsers that allows you to see an html page's code?
I tried opening it with TextEdit on my Mac but it says its not readable.
What's an easy way to take a look at/edit the code?
Thanks in advance for your help!

Android-apktool - A tool for reengineering Android apk files ...
http: / / code.google.com/p/android-apktool
It is a tool for reengineering 3rd party, closed, binary Android apps. It can decode resources to nearly original form and rebuild them after making some modifications; it makes possible to debug smali code step by step. Also it makes working with app easier because of project-like files structure and automation of some repetitive tasks like building apk, etc.
It is NOT intended for piracy and other non-legal uses. It could be used for localizing, adding some features or support for custom platforms and other GOOD purposes. Just try to be fair with authors of an app, that you use and probably like.

Google "apk manager"

Thank guys, however it says it can't be found - see this screencast I recorded: screencast.com/t/kII8UcBqE1RQ
Any ideas?
I feel like it can't be that complicated, but there is almost no info about in on Google...
Hello,
This is hard to search for this but I have tried, and have not found anything like my problem.
I'm following a tutorial for Android development with Eclipse, and I'm editing my view xml file using "Graphical Layout". I have a TextView component selected and go to the properties screen and select the Text property. An ellipsis (...) appears, and when I press that the button goes away, and the property is unchanged. It's supposed to launch a "Create new Android String" dialog, but, nothing. I see the problem with any property with an ellipsis.
I'm using latest Ubuntu, latest Eclipse (tried Java EE and Classic versions), latest ADT and Android SDK.
I have no idea where to start finding out what's wrong here since there are no error messages or anything. I would be most grateful if anyone could help.
(I wanted to post this to the android development section of the forum but it seems I don't have enough street cred for that)
Hello,
I have a lot of problems with omnia 7 due to app profile network of samsung haven´t got the profile of my operator. I can set it thanks to a post of here, but I think that it is a bit difficult and you need the computer to set it. As I have studied some of programming c#, I decided to make an app that set mms and internet. I have already done the screen and I´ve get to make that app create the file xml with the code in order to set mms and internet, but I haven´t found information about how execute/apply the file xml with the app. Where can I find about it?
PD: Sorry, I do not control English very well
Hi,
I guess it's a topic a bit complex, but can not someone help me with this?
You use an OEM COM interface, accessed from C# by using Microsoft.Phone.InteropServices.ComBridge. One easy way to see how this is done is to look at the source of an app that does it. If you can't get the source to DiagProvXML, you could always just decompile it (decompiling .NET code is pretty easy and there are several tools that can do it). There are several other apps that also use provxml; one or more of them may offer source access.
Hi,
Thank for your help and I can select the services that I have load, but I have a small problem that I hadn't taken into account. I know c# but my apps are a lot of more easy that diagprovxml, and I can´t find the part of program that I´m interested. I use "JustDecompile" to decompile the app. Could you tell me what class(or classes) is (are) what I'm looking for?
Thank you very much again
Hmm... it's not linked in my SIG because it's out-o-date, but you could try using Search to find my old DeployProvXml app. It includes a pretty straightforward example of using provxml.
Essentially, you need the following things:
The interopservices DLL (allows you to use the ComBridge class).
The OEM DLLs (DMXMLCOM.dll and such).
COM class and interface definitions for them in C# (this is the stuff with the [ComImport] attributes and the GUIDs).
ID_CAP_INTEROPSERVICES in your WMAppManifest.
WPInteropManifest.xml file in your project.
Use the ComBridge to register the COM interfaces, then create an instance of the COM class(es), cast to the appropriate interface type(s), and use a variable of the interface type like any other .NET object.
You can read a bit more about COM and native code in Heathcliff74's guide. It's aimed at making your own native libraries, so skip all the stuff about creating your own COM classes and writing native code. http://forum.xda-developers.com/showthread.php?t=1299134
Hi again, Does the method WP7RootToolsSDK.Environment.ProcessConfigXml allow to set the parameters that have a tipical xml file?
thank you again
I'm not sure what you mean by "set the parameters" but the Root Tools SDK does in fact allow you to consume ProvXML files now (I think it even supports the query provXML and returns the output, though I haven't tried).
Hi Guys,
I wanna start developing apps for the gearS2. Foir now I have some experience with html and several other languages mainly for windows applications and also last programming job was like 6 years ago so I'm not really up to date with all the different options for developing.
For start I tried to use the tizen SDK but I'm a little lost due to the variaty of options and also the quite buggy SDK. Installing the 2.4 SDK left me with an error for the simulator (hax not working). I t hink i got arround this by installing this manually. Emulator works now but for example the UI builder doesnt work. So my thought is to start a web app with tau as this seems to work quite reliable. My goal is to write a basic control of my hue lights (I know there is an app for that but I wanna try to build my own). My plan is to use an java lib for the hue commands and do the rest via the tau/html/javascript.
Now my question is if anyone can give me any advice on how to start developing. Does my plan seem valid. Can anyone help me or give me some tips? Maybe I'm missing something or someone just has some shortcuts.
Thanks in advance.

Hi.
I found this "howto" : http://www.tizenexperts.com/2015/12/how-to-deploy-to-gear-s2-smartwatch/
It helped me to successfully deploy a project sample on my gear s2 folllowing these steps :
- install sdk
- generate & configure author certificate.
- download, compile and run/deploy a project sample on the gear s2 (SensorBall).
During the "Request the Certificate" step, I ran into this java exception :
Unhandled event loop exception No more handles [Unknown Mozilla path (MOZILLA_FIVE_HOME not set)]

I'm on "debian jessie" with "openjdk7":
If this happens:
- install package "libwebkitgtk-1.0-0"
- add "-Dorg.eclipse.swt.browser.DefaultType=webkit" to you "eclipse.ini" file
- restart tizen.
At the end, you'll have a new app installed on your watch. You can recognized it with the tizen icon.
I hope this can help you.
Bye.
thank you for your feedback akaiah.
I found this site earlier, requested a certificate but then I couldnt find the site again. So thx for the link.
My problems are more linked to
a) the general structure of webapps for tizen
b) rusty coding skills (last time i coded was 6 years ago and mainly c# / object pascal for windows)
c) problems with tau / it's documentation
Maybe someone can help with a few detailed questions.
First question is regarding the online samples. I've found the following code in one sample for wearables (calendar app) but I don't know what this is and if I should be using stuff like this. It doesn't look like standard javascript to me but I can't find any API/library included either:
Code:
/**
* App module.
* @requires {@link Calendar/views/initPage}
* @namespace Calendar/app
* @memberof Calendar
*/
define({
name: 'app',
requires: [
'views/initPage'
],
def: function appInit() {
'use strict';
/**
* Initializes the app.
* @memberof Calendar/app
*/
function init() {
console.log('app::init');
}
return {
init: init
};
}
});
Second question is regarding jquery. Which version should I use and how am I supposed to include this? I'm using the 2.4 SDK download but programming a wearable web app with 2.3.1. I tried inlcuding jquery by downloading the latest version 2.1.4 (uncompressed) and putting it in my lib file folder, then including it in the html header. I have the feeling though that this is causing some issues. E.G. some notations don't work:
Code:
$( "#divname" ).innerHTML = "newtext";
doesnt work. No error just no result.
Third question is regarding tau. I tried to create a popup and register a callback for the popupafterclose-event like this but it doesn't work (event is not fired)
HTML:
<!--Popup HTML code-->
<div id="popup" data-role="popup">
<p>This is a completely basic popup, no options set.</p>
</div>
<script>
// Use popup events
var popup = document.getElementById("popup");
popup.addEventListener("popupafteropen", function()
{
// Implement code for popupafteropen event
});
</script>
taken form HERE
What am I doing wrong here? Is this the correct API im looking here or maybe does it collide with the jquery library?
For any tips I would be very thankfull.
Greetings
Björn
Wow thanks finally some one. I wold love to root my device ..
If theres a way.
If anyone was wondering about this issue, I kind of got this solved.
I just started an new project copied over all code and removed my jquqery imports and the code that gave me errors before just works fine. TAU in generell seems to be quite buggy and is easily be destroyed by an "unlucky" combination of UI changes (opening a popup or another window).
Even a week later I still don't know what the code in the calendar sample is from and tau seems not to be the most stable library out there. If anyone else has trouble starting developing for this I'm happy to share more experiences.
