[General Questions and Answers] -Gilgamesh-:
Ok, been using these forums for quite awhile to mod my various devices. However I've never had to post, so you'll have to forgive that this is in the wrong board as it wont let me post in the right one due to lack of posts.

I want to get into actually developing Android apps, and then eventually get into developing ROMs and such. From what I've seen apps would be programed in Java, and I've seen links to a few web resources to learn Java. But none on them answer what I am really looking to find out. I need to know what "flavor" of Java is best to use. Java 1? 2? 6? Java++? Visual Java? Etc etc etc.

I don't want to waste my time learning Java 6, if Android is only compatible with Java 4, for example. And vise versa. Like-wise I don't want to learn a version of Sun Java, if Java++ or Visual would be be better/give better functionality.

In closing, I just need to know what flavor of Java would be best to learn. Thanks.
[General Questions and Answers] aitorTheRed:
It's not really java, it's android.

Here you have everything to start:

http://developer.android.com/guide/index.html

And to set up the environment for developing:

http://developer.android.com/sdk/index.html
[General Questions and Answers] leblid:
knowing java is a good start, think of android like an advanced java applet programming.
[General Questions and Answers] -Gilgamesh-:
Yeah, exactly. And that's what I am looking for. Somehing to get my base knowledge started on. But their are allot of diffrent versions of Java and I don't really know which would be the best to use as a jumping off point.

I have also looked at the Android dev site, but it isn't really going to "teach" me from scrach.
[General Questions and Answers] aitorTheRed:
Again, if you plan to develop for android, it's better to focus on android, and not learn first java.. It's like learning first to ride a motocycle, and then go for the car.... It has some common ground, but..

If you want to learn from the scratch, the links I posted are your point. You can also take a look to the tutorials:

http://developer.android.com/intl/es/resources/tutorials/hello-world.html

If you still want to go through Java.. I reccomend you take a look to this:

http://download.oracle.com/javase/tutorial/java/index.html

http://download.oracle.com/javase/tutorial/

and start from Java SE 6 (http://download.oracle.com/javase/6/docs/)

http://www.oracle.com/technetwork/java/index-jsp-135888.html
[General Questions and Answers] -Gilgamesh-:
Oh ok, I get it now, thank you for breaking it down like that. I thought it was the exact opposite, I thought you needed Java to lead into Android. I'd looked at several books to learn Android, but all the reviews said that you should know Java before getting the books. (Hence where I got the idea) I actually read this post earlier, and I have given the Developer section of the Android site a LOT deeper look, and it looks like you were very much correct. Upon first glance I didn't think it was actually be what I needed. Thank you for your assistance and I am sorry for the missunderstanding.
[General Questions and Answers] aitorTheRed:
No need to ask for sorry :) we all have to start sometimes from zero ;) it's true that knowing java helps, but I think that if you have some notion on OOP (object-oriented programming) will be enought :)
[HD2 Android Q&A, Help & Troubleshooting and Genera] Skellyyy:
So guys I've just switched ROM to this and I'm loving it but only one problem. I don't there is DATA2SD which I rely on. I'm using MyBackup to restore my apps to my phone but its annoying that I can't reinstall them all because of the internal memory capacity (22mb).

It says in the thread

How do I do that? I know you type that in cmd but nothing after that. Do I need any programs on my phone/PC?

Oh yeah, I have my SD card partitioned with a FAT32 and a Ext3 partition. :)
[G2 and Desire Z Q&A, Help & Troubleshooting] ptesmoke:
hey peeps, I'm travelling to key west florida next week and would like to kno if I could get a pay and go service with tmobile oe verizon on my dz? rogers wants $25 extra a month for international text which is 100 sent ultd receive. I'm sure I can find something better down there? I'm sim unlocked, I kno tmobile will work but unfamiliar with pricing etc and I know there's a verizon in key west but dunno if they use the same freq bands.

thanks for any info you guys can help with!

cheers
[G2 and Desire Z Q&A, Help & Troubleshooting] martonikaj:
Can't answer for sure because there can be frequency issues depending on your carrier. But your options are going to be either T-mobile or a regional carrier that covers that area that will give you a prepay SIM. Verizon and Sprint are CDMA aka no SIM and won't work.

Just looked at T-mobile they offer a prepay plan of $30 for a month of service with 1500 talk&text and 30mb of web. You'll have to check coverage though and as I said you need to make sure your DZ will work with the frequencies that T-mo is on, which I think is 1700mhz.
[G2 and Desire Z Q&A, Help & Troubleshooting] ptesmoke:
ok I will see what google can find for me :) thanks for the input! even still at 30 a month I get more than rogers can cover me there. only issue is finding a tmobile store or. like u said a local provider. I will do some searching here in a bit.

if anyone else has any opinions or advice its welcome :)
[G2 and Desire Z Q&A, Help & Troubleshooting] Ashex1:
I think the Rogers desire z uses the same 3g as AT&T. If the Rogers phones work on the Bell 3G then this is true.
[G2 and Desire Z Q&A, Help & Troubleshooting] funkadesi:
I 2nd ^^ this guy.

I think rogers is using the same 3G bands as AT&T, so you'd have to....

1. Unlock your DZ

2. Change the APN settings to AT&T

3. Enjoy your trip to florida :-)
[Milestone XT720 General] yoppoyyoppoy:
Does nayone have the original WIND Stock firmware, i want to get back to 2.1 from 2.2
[Milestone XT720 General] R-D:
There doesn't appear to be an SBF for Wind anywhere on the net.

If you took a Nandroid backup of your Data and System partitions before installing those from Dexter's release, you can simply nandroid your way back to 2.1 by restoring your backup, and doing a wipe.

If you didn't take a backup of your device, you need to reflash with a 2.1 SBF.

Note that those on the http://and-developers.com/sbf:xt720 site seem to be disappearing, both the BrightPoint and the Cincinati Bell files are now 404, so you will have to find one elsewhere.
[Milestone XT720 General] Accophox:
It looks like all of the sbfs for the xt720 have been pulled o.o

Motorola must be really peeved about people hacking a 2.2 onto it. x.x

sorry mate, until boot loader is unlocked we can't dual boot, or until a developer has a work around for the locked boot loader :L
[XPERIA X8 General] alil:
if this dual boot is possible for x8, hope devs can help us to crack the BL right after the 2.2 and 2.3 projects.. cheers..
[XPERIA X8 General] XperianPro:
You can boot from sd card and from internal memory then you cqn have dual rom.

I just recently rooted and I have obtained s off successfully. But I can't seem to get the root priv to stick. I would appreciate any help I can get.

Thank you for reading.
[G2 and Desire Z General] zzrssh:
Which method did you use?

I got my phone a few days ago (G2), followed the instructions here: http://xdaforums.com/showthread.php?t=928160 - had no problems with keeping root when I had stock rom, and running CM 7 nightly, still no issues.

If you can't keep root, sounds like you don't have perm root.
[G2 and Desire Z General] Mftek1:
I used the original method posted by unforgiven.

I already have s off. But when I run temp root again it doesn't stick.
[G2 and Desire Z General] zzrssh:
Why not try gfree to perm root?

[Motorola Droid and Milestone General] lilbballer27:
Ive flashed recovery many times in clockwork mod and everytime I try booting into recovery mode it just boot loops. What am I doing wrong?
[LG Optimus 2x] Chopaan:
I've seen other phones that will be released this Q1 or Q2 having 1GB of RAM whilst the Optimus 2X only has 512MB.

I myself have kind of got the feeling that 512MB's would be enough and that 1GB is unnecessary, but I would like your opinions, and maybe an explenation to why 512MB's would be enough?

Since Atrix won't be released in Sweden that pretty much leaves it to Optimus 2X or the Galaxy S2, but the S2 will probably be like 200 dollars more. Would that really be worth the money RAM-wise (other differences doesn't matter that much to me)?
[LG Optimus 2x] Sjael:
I'm of the mind that 512MB will be fine for the forseeable future. If you consider that the most demanding apps are typically games, and the most impressive games (since GameLoft, Epic etc have signed on with nVidia...) will be developed to Tegra 2 specs, I can't imagine those Tegra 2 specs would preclude running on 512MB of RAM. Following that assumption, by the time 512MB of RAM isn't enough, you will probably be due for an upgrade anyway.

I'm starting to think that the only reason the Atrix has 1GB is because the WebTop mode runs well over 512MB in typical operation. Then, of course, the Galaxy 2 has a gig so that it doesn't look inferior on paper.

Just my conjecturous 2 cents. :P
[LG Optimus 2x] Chopaan:
Thanks for your reply! I also thought about the RAM being for the WebTop but then Samsung released the S2 lol.. I would probably agree with you that 512MB will be enough in at least the coming year or so, hell, you can almost run a game like World of Warcraft on 512MB RAM.

Maybe Motorola and Samsung are just putting in hardware that is ahead of the future to atract the customers that want 'the best'. Of course, they are probably slightly better but from what I understand it is kind of hard to fill up 512MB RAM which they also say in Anandtechs review of the Atrix.

http://www.anandtech.com/show/4165/the-motorola-atrix-4g-preview

If only LG could put in at least 768MB I wouldn't have to worry :(
[LG Optimus 2x] svengalis:
Have to agree with Sjael about the 512MB of RAM in the Atrix being for the laptop dock. In that preview you posted in the benchmark tests the optimus came out on top of the atrix pretty much every time. So don't let the 512 MB of RAM detour you!
[LG Optimus 2x] pokerfake:
I would not mind 512MB RAM(Actually, you can use only 372MB of ram because of the android system)

512MB ram is not that small, and there is no app that needs more than 512MB.

I'm using Optimus 2X, but 512MB RAM was okay
[LG Optimus 2x] Chopaan:
'Okay' doesn't sound too convincing. Could you tell us about the phone in general? Are you satisfied, how is the battery life etc?
[LG Optimus 2x] pokerfake:
Battery time is simuliar with Samsung Galaxy

LG home sometimes reset after I play some heavy 3D game. I think that its because of RAM, but this problem does not happen if you change your home program
[LG Optimus 2x] tinzy71:
What about gps ?
[LG Optimus 2x] pokerfake:
GPS is waaay better than Samsung Galaxy S
[LG Optimus 2x] Chopaan:
The LG launcher doesn't look too attractive anyway so i'll probably go for LauncherPro :)
[LG Optimus 2x] tinzy71:
Really ? Oh, this is a great news !
[LG Optimus 2x] gydnjsdl:
1GB is better than 512MB

but....... i think 512 is enough, also
[LG Optimus 2x] djmcnz:
Well we now have some empirical evidence...

The +64MB RAM kernel gives back 64MB to the user and it makes a *huge* difference to performance in general day to day use for me. I no longer need to use minfreemanager and my launcher and background apps hardly ever get shut down by the system now.

I used to be of the mind that 512 was enough (=372) but with +64 (=436) there's a world of difference.

So, in my experience 512 is a constraint.
[LG Optimus 2x] spawndk:
Its not the 512mb itself being the limit here, its the way these 512mb are used and how Android is configured to manage the memory by the manufacturer - but yes more ram to work with are allways a benefit.

512mb is plenty in the HTC Desire which default has about 440mb for the user, while the LG only has 372mb (more ram allocated for video than the Desire perhaps ?)

Furthermore the default minfree setting in the Desire is configured to allways leave 140mb free, while the LG is default configured to only leave around 80mb free.

This cause the LG to run low on memory, needing the system to free up memory by shutting down apps that are preloaded, faster and more often than on the Desire.

The extra 64mb you free with the other Kernel can be configured either as more ram for preloadet apps or as just free ram - depending on how agressive you set the minfree setting. The result you get will be a combination of this - if minfree are still set to 80mb then the 64mb are just used to preload more apps, which you will feel as a benefit if switching to one of these preloaded apps, but wont feel as a benefit if you need to run an app that use up more than the free 80mb and which hasnt been preloaded. On the other hand you could divide it and set the minfree setting to 110 and let the rest 34mb be used to preload apps in, that way a running app could use more ram before it would need to shutdown preloaded apps.

I cant say which setting would be the best overall - but for certain the configuration of the memory works better in the Desire than the one in the LG - despite both having 512mb ram

[Android Software Development] TxMoose:
Howdy all,

I am writing a simple flashlight app as an assignment for a class at school. The class is "Application Development for Mobile Computing".

We were told to have a white screen and options for different colors and then to add something creative on our own. I would like to use the camera flash as that creative element.

I have done my research and scoured this forum, but I can't seem to find anything. I have found that I should use this function within the Java code:

Camera.Parameters.FLASH_MODE_TORCH

But I can not get it to start the light. It just causes a FC. Can anyone give me some direction on this?

Thanks, all.

[A7 General] Okewy:
Hi Everyone,

I plugged my A7 through the HDMI port to my projector, it works with no issues whatsoever! But the sound jack doesn't work once the HDMI is plugged. Is there a way to force the sound to work even if HDMI is plugged in? Or even the speakers?

Thank you,

Marc
[A7 General] netstat_EVO:
I have run into this issue with other devices, not the A7 yet though.

Once HDMI was connected the device only wanted to send audio over it and disabled all others.

My projector had RCA L/R out, but no internal speakers.

What I ended up having to do was get a RCA -> headphone jack adapter from Radio Shack and use regular PC speakers from that.

Probably not the solution you were looking for, but I hope it helps.
[A7 General] Okewy:
Possible solution

The option I'm looking at right now is an HDMI switch. It has 2 inputs for HDMI and outputs 4 HDMI and an RCA. I'm not really insterested in dishing out the 70$ for it though.

i see this is another one of those needed forums that the people that have the answers think "they have better things to do" way to keep the spirit of open source alive.

and go ahead and say oh they are working on this and that... reading new posts and replying take 15 min of your day i'll just figure it out myself... without this forum, better off without the elitists

Hmm. You can root your phone and install application that can delete applications that you can't delete without it.

You need to delete phone and anything u wish to not have with it.

Watch it.

It is not safe beacuse I am sleepy now a lot. And having a lack of time to answer normaly and check it all.

But next to me is sleeping china joyplus m778 tablet waits to be rooted. But I am unavalilable beacuse of the programs freeze (super one click 2.1.1)

Your tablet is like a psyco wannabe mobile.

And that is the main reason of turning it up by itself, and spend so much battery.

i know my post is unusable but there is some valuable information I hope?.

[HD7 General] GoodDayToDie:
Wow, yousuf18691... way to necropost a thread from February.

It's already possible (and has been for many months) to put HSPL on the HD7, although if you have the latest set of updates (SPL 5.x) that's currently not working.

As for putting Android on the HD7, first somebody would need to port Android to the HD7, and nobody seems to have done so yet. There's plenty of Android phones if you really want one, though - nobody is holding you at gunpoint and making you buy a Windows phone, I assume.
[Nook Color General] waiteck:
Hi guys. I was wondering if there are any issues making bootable SD cards for honeycomb or froyo and etc.

I am thinking of buying an micro sd card for the nook color.

which one of you guys would recommend?

16GB class10? 8GB class10?

I have seen all mostly using 8gb or 4gb at most. is there any issue using 16gb class10? please advice. thanks!
[Nook Color General] eyecrispy:
should be fine.
[Nook Color General] therealguppy:
If they are same class then you should get about the same speed off either and all your looking at is size... if you want 8gb of space get the 8gb if you want 16gb of space get that one instead.....

I would not recommend using anything lower than a Class 6 card however.
[Nook Color General] RootNewbie:
I've run HC on a 8gb class 4 card for a while. No real problems. Maybe lags a little time to time, but that may also just be the rom.
[Nook Color General] waiteck:
i see... initially i thought there were issues with class10 16gb cards.

thanks all for the input! :)
[Nook Color General] hacku:
I purchased two 8GB Class 10 cards. I use one for storage and the other for Honeycomb and it runs great.
[Nook Color General] daemonfly:
Can the Nook actually even use the speed of a class 10? I know many phones can only fully use 4 or 6, with the only benefit of 10 being faster transfer while connected directly to PC. Class 2 is just slow on everything, of course ;).
[Nook Color General] Stevr:
I tried class 10 and class 4 16gb cards because I really wanted the space. I had all sorts of problems running on the class 10 once v04 honeycomb came out and the class 4 would run froyo and HC but it was so slow it couldn't be used. Some people seem to be using them but when I relaced it with a 8gb class 10 Patriot card, it runs great.

As to whether the nook can use a class 10, I don't know. I certainly know it MUCH faster with a class 10 than a class 4. I also bought a class 6 AData card but I have not tried it as a speed comparison. I was just tired of running back to the store to return them and test another so I bought two and started with the fastest one.

16gb might work with future versions but for now, I am sticking with 8gb cards.

I recommend the Patriot 8gb Class 10. The model I bought was the LX Signature Series: PSF8GMCSDHC10
