[Q] modifying AOSP Calendar issue

Hi, so I'm a student learning Android app development and trying to modify the AOSP calendar to fit my needs so I downloaded the source code from git and made a project with 2.2 FroYo as the basis through Eclipse with ADT and all but I ran into a problem. So I run into:
android.provider.Calendar cannot be resolved into a variable
I did some research and found that the SDK apparently does not have the calendar code nor the database which is why I am running into these issues. So I learned from here jimblackler[dot]net/blog/?p=151 all that. He does have a solution except I have no idea what he is saying. He posted a bunch of code but I have no idea where that code is supposed to go in and I dont understand what he is trying to do with "content://calendar/calendars"
So I just decided to ignore the errors and obviously I couldn't compile it through eclipse so I made an unsigned apk and tried to install it unto the Emulator via ADB but as an unsigned apk it would not let me install it I tried to sign it by going through google's developer site but I am at lost again. I'm a noob to these things unfortunately..
I was wondering if anybody could help me out and point me in a good direction, I would be eternally grateful. Thanks.
P.S. sorry if I was being vague about the google's developer site and source code site but as a newbie I can't post links properly

[Q] Informations for building a new Device tree for a unsupported Device

Hi Everybody,
I want to ask for some informations what is need to do to build SlimRom for a new device. I found a lot of informations about CM, but nothing is really in a way that I really know what I have to do at the end. So is there a Howto, which describes it a little bit more in detail? A lot of howtos was found which describe to get a build-system, and to generate something for a know device. But everybody then describes only: you have to get the vendor files, made your Board-config but only on a very high level.
What I did:
- set up a building-server on ubuntu.
- get Slim-Sources branch JB4.3, and build the version for galaxysmtd to be sure that the buildprocess is ok.
- get "Nonreallyfree"-Opensources from Samsung for my I8200, and try to put them in the right places, and try to implement all needed files in the device/samsung/i8200 folder.
Up to now I think I have everything in place more or less, but the system told me that there is no rule for make 'bacon', but lunch seems to work right with setting the variables...
Up to now I did not used the blobs of the devices. The question is, if that is needed if I have the sources from open Samsung?
I know, jb43 is not the newest, but I start here, because up to now the sources are based on that level, and the kernel have no selinux implemented... If this start point will work, then I will try to go ahead with higher versions... end goal will be Slimkat...
Any help is very much appreciated!!

[Q] Need Help with Compiling AOSP Nougat - Proprietary Binaries

So I've decided to give building Android a go, considering we've recently obtained the source code for the device in question (R1 HD) and no one else has done this yet for this device. I've been following this guide, since all the other guides I've found assume there is already a GitHub repo for your device. There's literally NOTHING out there regarding this device, aside from the kernel source we've obtained in the form of a .zip archive.
I've done everything up to and including pulling the 7.0.0 r1 source with the reop sync command, and I am now stuck on the Preparing to Build section. The first thing it talks about at this point is implementing proprietary binaries into my source. I have no idea where to find proprietary binaries for my R1 HD, let alone if they even exist out there to be implemented. Literally all I have regarding this device is the kernel source in a zip file. I can't find anything else out there nor do I really know what to look for.
Can anyone tell me what to do here? I've never compiled Android or even a kernel before, and I'd really like to get something out there for this device that others can base their work off of.

Simple way to port "official" Android ROM (AOSP) to specific device

Hi,
AOSP (check: source.android.com) is where one can find kind of official source code of Android.
Then you download it, compile it - and you have ROM ready to be flushed.
1. Is it will work for any device?
or, and I guess this makes more sense-
2. One need to modify according to his device spec. some parameters in the code. For example somewhere in the files there is a file with code holding some constant SW parameter called something like "double CPU_HZ" and you need to type "=1500;" because this is correct for your device.
Is there a simple guide to all device specifc parameters (and where to find them in the code)? Because if so - anybody can Download->follow the guide, modify all params according to his device spec->compile->flush->you have clean Android OS ready to go.
Thanks,.

How one can debug apk without sources or open source app apk without full recompile?

Hi,
Is it possible to debug apk without sources or open source app apk without full recompile?
I needed and tried to debug (Android Stock) Email app , found its sources from AOSP code storage,
opened it in Android Studio, was forced to compile it back - I mean Android Studio opened something available Debug" button, codes were shown only .smali, then I attached original source codes...
But I didn't able to debug it, since it stopped with some mysterious error, something like: "certificates is not coincide with required one" or similar...
So, what I can to to do that?? It is very difficult to compile app newly since it needs build system to be adopted for building as separate android app.
Thanks

Was this wrong place to ask? I can not write into "Developent" Thread on this Forum yet.
