Any one can help interpret the relation between the table "contacts" and "raw_contacts"?Is it one-to-one or one-to-many relation?I am puzzled because the SDK seems indicate it is one-to-many relation but after I checkout all data from the database table,I found it is one-to-one relation. And is there any detailed relation diagram describing android database tables?

I was just wondering a few things
1. I'm getting the Nexus One and putting the SIM Card from my other Rogers phone into it... will there be any problems/pitfalls i should look out for?
2. As far as applications go, if I don't have a data plan, will i be paying out the rear end to use apps such as facebook, last.fm etc?
3. Is there an app that lets you text/call for free?
4. Do you have to have a data plan to download apps when not in range of WiFi (if so how much does it cost to browse the store and download an app?)
5. Does it cost anything to use the GPS (Do you need a GPS plan?)
6. Is there an app that lets you track Text messaging usage, call time, data usage etc?
I am a current iPhone 3gs user migrating over to Android this Friday and getting the Evo 4g. Now, all iPhone/iPod touch screen sizes are the same and all the hardware specs are the same for the most part, but with Android you all kinds of resolutions, screen sizes, processors, etc etc...
Are all apps made for Android stretched to accomodate bigger screen sizes? For instance, I have played with my friend's Droid on Verizon and the screen is 3.7" at a resolution of 854x480 and he has showed me games on it like Gameloft's NOVA which is a full 3D first person shooter. So his phone essentially has a bigger resolution slightly than the HTC EVO 4G but smaller screen size (3.7" vs. 4.3"). So would the same game be stretched to fit my phone?
I'm wondering with different apps, are there any conflicts in relation to different spec phones?
I am trying to learn opengl stuff on Android. In the gl.gltranslatef(x,y,z) call, I am shifting my texture by some units in the +ve x direction. But I am unable to find the number of pixels does 1 unit of x belong to?
Here is what I am doing:
I call gl.glviewport(0,0,width,height); // This will set my rectangle with 0,0 as lowerleft corner and then extend it to accommodate width and height.
Then
I call to gl.glfrustrum(-5,5,-7,7,3,7); // I am little confused how this call is using the dimensions I set in gl.glviewport.
How will -5 to 5 units from left to right in the above call, translate to pixels on the screen of android?
I mean if width = 320 and height = 533 pixels, then what will be the number of pixels occupied on the screen due to the gl.glfrustrum call?
I am experimenting in the gl.gltranslatef call by specifying xshift as 5.0, but it does not translate the bitmap at the right or left corner of the screen, when I increase it to 6, part of it is still visible on the screen.
I am searching for the maximum number of units (in terms of X) which will represent extreme corners of my android phone screen.
Im on 3 and as of yet there is no update to 2.1 so im on 1.5 ..now this maybe the most stupid question ever but in the sticky slug posted it says coustom ROM'S and all of them are 2.1 does that mean i have to have 2.1 update to be able to use one of these ROM'S, if not what are your recommendations for a custom ROM ie what one from the list is best and why . what will they do/ what do they do , will it improve this already good phone and in which ways , also if i am able to put one onto the phone how do i do it.

View 1 Replies View RelatedI've been curious as to all the optimizations that go into the building of an .apk. I'm curious because of two things I've tried in the past to bring down the size of my .apk:
I have had a few large json assets in projects before, as well as a static sqlite database. I tried bringing down the size of the apk by gzipping them before the build process, but the resulting size is exactly the same.
I just today tried pngcrush on my /drawable/ folders. The resulting build was exactly the same size as before.
I would think that perhaps #1 could be explained by the zip process, but simply zipping the /drawable/ folders in #2 result in different-sized files. Perhaps the build process runs something akin to pngcrush?
Regardless, I was wondering if anyone knew where to find a detailed description of all the optimizations in the Android build process. I don't want to waste my time trying to optimize what is already automated, and also I think it'd help my understanding of the resulting apk.
They sure didn't ship one with the phone. Is there a Droid (or Android 2.0) User's Guide on the web that gives detailed operation on all the Droid functions (including tips & tricks)? It sure would be handy!

MAC/LINUX ROOT TUTORIAL
Many people have said that they are having difficulties understanding the root process, so I typed up a complete tutorial exactly the way I rooted my phone. All credit goes to wag3slav3 over at XDA, Root for ERIS LEAKERS! - xda-developers, I just expanded on the instructions
1.Download the Android SDK from here: Android SDK | Android Developers
2.Download hack-v4.zip from here: Multiupload.com - upload your files to multiple file hosting sites!
3.When the hack-v4.zip is done downloading put the files of the folder into the tools folder of the already extracted android sdk. The tools folder can be found at /where ever you put the sdk/android-sdk-86_mac/tools.
4.Download a custom ROM, I recommend KaosFroyo, but you can choose whatever one you want. Place the .zip file on the root of the SD Card (ie. Not in a folder). PS. If your mac automatically decompresses the .zip, you can find the original .zip file in the trash. For this plug your phone into the computer, pull down the notification bar at the top of the screen on your phone and tap the USB connection notification, then tap Mount as Disk Drive. Copy the .zip onto the phone.
LIST OF ROMS: Known Droid Eris Roms, Patches and Hacks - UPDATED 05-11-2010 - xda-developers
5.To change directories to sdk/tools folder:
1.Open a new terminal window and type cd [space]
2.Find the android sdk in a finder window
3.Drag the folder that says tools to the terminal window and press [ENTER]
4.There now should be the word "tools" in front of the computer name/your name in terminal.
6. On your phone go in to Applications->Development->USB Debugging and make sure it is checked. Plug your phone into your computer, select "charge only" not Disk Drive mode
7. To test if your ADB is working run " ./adb devices " . If you get an alphanumeric code that starts with HTXXXXXXXXXX and says device then you are all set.
8. Once your phone is plugged in run " sh runinlinuxfromtools.sh "
It takes a while to load, but you should be in Amon's recovery after its done. If you don't see Amon's recovery than try step 9.
9. If you get "adb: command not found, try " sh runinlinuxadb.sh "
10. Your phone will now boot into recovery. From there select "Backup/Restore" > and NAND Backup. Let it load, it takes a minute or two, then return back to main menu. Then select "Wipe" > choose Wide data/factory reset. Return to menu and select "Flash zip from sdcard" > find your .zip file that you downloaded (the ROM). It should have the name of the ROM somewhere in the zip name. Let it do its thing, then select reboot option.
11. Congrats, you have successfully rooted your phone! If your ROM does not already include "SuperUser.apk", download and install the app as soon as possible.
12. [OPTIONAL] If you want to change the boot loader to the engineering bootloader (ie. S-OFF) then follow these instructions How To Install Engineering bootloader FOR LEAK ROOTERS - xda-developers
But I have found a change that will make this much more hassle-free. On the last step when you see you have successfully changed the HBOOT, do a battery pull, and start the phone back up again. You do not have to do those commands for the final step. Then complete the root instructions above and you will have a changed boot-loader and root.

FLASHING CUSTOM ROM's (Once Root is gained)
In order to flash a new ROM after obtaining root you simply:
1. Find and download the ROM that you want to use.
2. Mount your PC and copy the .zip file over to your SD card like you did for root.
3. Turn off your phone and power it back up while holding down the up volume key.
4. After booting into Recovery, go to Wipe and wipe factory data along with Dalvik Cache.
5. Back out of the Wipe menu and go to Install from SD. Your ROM will be there. Hit install and it will put the new ROM that you want, on your phone.
6. Reboot and you will see a boot animation screen for several minutes before it loads your new ROM.
7. Repeat this procedure with a Nand Backup each time you get a new ROM set up.
I love weather apps, but I've yet to find one that I really like that much. A lot of them are pretty good, some have this function or that function but none of them seem to have everything.
Anyway, years ago I used an app called PocketWeather on Windows Mobile and used a skin called Wonder Skin. It looked like this:
Notably it has humidity, pressure, forecast, current conditions (inc wind), temperature graph etc.. It had everything at a glance, I rarely needed to look into the app at all for this.
Most weather apps I can find today just have some current info, mostly seem to be clock widgets + some weather info.
Any weather widgets with more details on them? I don't really want to get into the complexities of making my own with something like UCCW but I'm pondering it.
it's possible to get an app that basicly gives a detailed description of what files an app is accessing when it's running, i can't seem to find one and i'm wondering if it's possible to get one done.

I'm interested in android activity lifecycle and I would like to get more detailed description/documentation/reference than widely available basic (onCreate->onStart->onResume) one.
My need comes from realizing that starting new activity (Theme.Dialog styled) from onAttachedToWindow() greatly improves response time if comparing to starting it from onCreate(). I wonder how this onAttachedToWindow() fits into whole android activity lifecycle. Official API ref description "Called when the window has been attached to the window manager" doesn't help a lot.
If you having a tough time finding the download link, just scroll to the bottom of the page and it will be the first main body of text (blue in color) from the bottom! Also, this is NOT Mac supported as mentioned below, pretty much the only bad part...
Well I've had alot of people messaging me about converters for music, video, photos etc and I decided to just post up a thread for people to ask questions if they need to. Anyways, the best converter that I could reccomend, HANDS DOWN for any needs whether they be for your phone or not is the SUPERC converter which can be found here
With it you can convert virtually any media type into any other media type. For starters here are some steps...
1. Drag your file to be converted into the que.
2. Double click on it to bring up the detailed info.
3. Select the output you want from the drag down menu at the top left
4. Match up the info for the video and audio (if applicable) to the details you brought up about the clip. Yes this is a bit techy, but its really simple, just read and click on the buttons. If your framerate or bitrate doesnt match up, always pick the lower one. I.E: If you have a framrate of 96, and the options are 108 and 90, always pick the lowest of the two.
5. Just click convert! and wait until it gives you an output file size!
Yes it may seem a bit overwhelming at first, but its great to be able to convert anything into, well, anything. I use it for all my converting needs, and even if your not a techy person, even if you dont know what a bitrate is (shame on you! haha jk) its still a great program which is easy to use, whether you have circuit boards instead of brains or not.

1) How can I get the phone to add new contacts created on my Droid into "My contacts" in Gmail?
2) I'm trying to understand the point of "All contacts". Why does Gmail want to keep a list of anyone that I've ever sent an email to? Otherwise, it'll be simple enough to just merge the two groups and call it a day.(Note: When I bought my Droid I did NOT have the VZW sales person transfer my contacts or any data from my old Blackberry to my Droid. I used Google Sync on my BB and synced my contacts from my BB to Gmail, then when I got the Droid, it automatically pulled my contacts from Gmail.)(FWIW, yes, I did a search and found two great threads: http://androidforums.com/support-troubleshooting/15042-how-do-i-push-droid-contacts-back-gmails-my-contacts.html and http://androidforums.com/motorola-droid/15069-contacts-dont-really-synchronize.html but I have a different situation than most of those guys and I'd actually prefer to sift through and merge a couple of contacts from "All contacts" to "My contacts" every once in a while than deal with a backup and factory reset.)
