Android :: Build Performance Of 2.2 Vs Older Sdk Implementations
Jul 24, 2010
I have been building all my apps against the 1.6 version of the SDK until just recently when I switched to 2.2. I use ant to handle my builds and a normal build time for one of my apps was about 30 seconds. Now that I am building with 2.2 (that is the only change) it is taking over a minute to do the exact same thing... I was just wondering if anyone else was seeing a significant increase in the time it takes to build with 2.2.
When I make incremental changes to code in eclipse I am now noticing a "Building workspace: (xx%)" which takes a VERY long time in 2.2 compared to 1.6. I hardly every used to notice this because it was so fast. Now I notice it all the time.
I really hope that as we see additional sdk version come out that things just get slower and slower... also, I had read that with 2.2 we would see "significant" increases in performance on our existing hardware (devices). I'm definitely not.

My application is built on 2.2, but it is backwards compatible down to 1.6. I've used reflection for the newer methods. When I try to run it on an emulator in Eclipse, it only lists my 2.2 AVDs. I need to test on 1.6 to ensure compatibility. I've tried building with Android 2.2 and with Google APIs 2.2 with no luck. (what's the difference, anyway?) I have set <uses-sdk android:minSdkVersion="4" targetSDK="8"/> in my manifest. I also tried targetSDK="4".

I'm looking into writing an Android game, tough I don't curerntly own an Android device. For those of you who own a device, how does the performance on the emulator relate to real device performance? I'm especially interested in graphics related tasks.This obviously depends on both the machine running the emulator, and the specific device in question, but I'm talking rough numbers here.This question is a duplicate, but since that post is heavily outdated, I figured it's irrelevant by now.

I have a .jar in my Android project which has many references and uses of the java.awt.* classes and other classes not available on Android. How can I provide my own implementations of these classes so that I can embed the unmodified .jar file (the only modification is being ran through dx) in my Android application and it will use my own class implementations?

I think the answer is going to be no, since the only question on the matter on SO is about memory requirement. However, before I go porting unrar to the android, I'd like to know if someone has done it already.

I found a post from a while ago that addresses a similar question but I think it's a bit outdated. I realize implementations of JPA tend to be more on the heavy/dense side, so if you know of any lightweight (non-JPA) ORMs I'll most certainly appreciate your input. I did see the answer about ActiveAndroid in the other post and am curious to know if anyone tried it out.

I have class A, with methods foo and bar, that are implemented by A1 and A2. The functionality in both A1 and A2 is the same. In other words:
public class A {
public int foo() { return 0; };
public int bar() { return 1; };
} class A1 extends A {
public int AnotherFooFunction() { return foo();
} public int AnotherBarFunction() { return bar();
} } class A2 extends A {
public int AnotherFooFunction() { return foo();
} public int AnotherBarFunction() { return bar();
} }
Is it better to keep the code in this fashion, or to swap out those virtual methods as static methods? (In Java, everything non-final/non-private is considered virtual, right?) According to the Designing for Performance section in the Android Developer Docs, I should swap out these virtual methods for static ones. So the above becomes:
public class A {
public int foo() { return 0; };
public int bar() { return 1; };
} class A1 extends A {
public int AnotherFooFunction() { return A.foo();
} public int AnotherBarFunction() { return A.bar();
} class A2 extends A {
public int AnotherFooFunction() { return A.foo();
} public int AnotherBarFunction() { return A.bar();
} }
Is this how it "ought" to be? I fully realize that I may be misinterpreting this paragraph in the docs.

I downloaded the Android 2.2 source code and try to build it. When I executed the make command, I got an error here like this build/core/java.mk:20: *** frameworks/ex/common: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. Then I changed the frameworks/ex/common/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7. Next place, build/core/java.mk:20: *** external/jsr305: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. I changed the external/jsr305/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7
Last one, build/core/java.mk:20: *** external/guava: Invalid LOCAL_SDK_VERSION '8' Choices are: current 4 5 6 7. Stop. I changed the external/guava/Android.mk to LOCAL_SDK_VERSION = 8 from LOCAL_SDK_VERSION = 7
By these changes the code started the compilation.
1. Why the error occured?
2. Changes which I did is correct or not?

I just sold my GW620 (LG Intouchmax) and have a little bit extra money to spare, and I was wondering, what's the best Android phone you can get for around 80 - 110 pounds?
I'm looking at the Galaxy Portal, I've already had the Dream G1 and HTC Hero G2.
I've also looked at the T-Mobile pulse.

I'm using the level 5 sdk to compile my app, but set my target to sdk level 3 in my manifest. All is fine.
I may need to use some level 5 classes (ExifInterface) though. What's the right way to go about using them while not fouling things up for devices running older sdk versions? Do we simply restrict use of the newer API methods to completely separate class files? Something like this:
CODE:.................
so as long as the api methods are completely separated into files that the older devices won't invoke, we should be ok?

I have recently updated my app to a build target of SDK version 8 in order to include the App2SD feature for my users. However I have had reports of devices on SDK 3 (1.5) having problems starting the application, with the following stack trace: If i change the build target back to version 4 as it was previously this issue goes away, also if i remove any graphical resources from my XML files this issue goes away.

I'm trying to prevent the situation where an updated version of my app restores using a bundle written from a previous version of my app. In other words:
1) app v1 stops and calls onSaveInstanceState
2) app v1 saves the bundle
3) user goes to marketplace and updates the app to v2
4) user starts the v2 version of the app
5) v2 version calls onCreate passing the bundle with v1 data
Is that even possible? Do I need to worry about it?

Now that Flash Player is no longer being updated for older versions of Android and is completely incompatible with ICS+, couldn't browser makers simply build Flash Player into their browsers, similar to the way it was built into SkyFire for Windows Mobile a few years ago? Couldn't it be made available as an addon for Dolphin HD?

I stupidly installed the Orange ROM update on my Tattoo and am now having the issue with it only ringing once. Is there anyway I can roll back to an older ROM? I've downloaded V 1.65.405.1 but the phone won't let me install it. I remember on an old SPV phone when I was trying to remove the Orange branding I had to unplug it when it was trying to do the ROM update which corrupted the phone and allowed me to install the unbranded ROM. I'm wondering if doing that would work but I don't wanna risk it.

In the regular email app (not gmail), when new mail is loaded, older emails dissapear.
This is normally not a problem because I have the phone email app set to not delete mail from the server.
I received a very important email the other day. It got deleted by my phone when checking for new messages, and, of course, the original is deleted from my server for some reason!
Does anyone know what happens when older emails disappear? These emails can be just a day or a couple hours old.
There is no setting in the email app for saving emails.

So I am running an older version IC3ROM (4+ months old). When I left, Froyo was a buzz word, and leak rooting was a dream rumored to never happen. Is it time to upgrade to something new? I can't really complain about IC3ROM, as with Launcher Pro, it has been great. I don't particularly like the idea of starting over, but if there's something out there worth it, I'd give it a go. Opinions? I don't really care about Verizon's interface as I always replace it with launcher pro, but performance and stability is #1 concern.

Does anybody have a link to get an older version of Dialer One? Is there a way that I can revert back to my previous version? I updated it to Version 1.2.6, and I must say the new changes are terrible. Facebook pictures no longer sync. 2.) Calling a number after dialing is more difficult as instead of having a fairly large area to click to call, you have to exactly touch the tiny phone logo, 3.) Before I could click the bar to change from contacts, recent calls, and favorites. Now I have to swipe to go between the three. The one positive with the new upgrade is the developer fixed a bug where the dialer would always crash if you attempted to add a missed call number to your contacts. Not that works fine. But losing the other three things are enough for me to want to go back.

It is pretty easy to install. If you've installed HTC Sync it may cause an Android Debug Bridge error. If thats the case then just open task manager and close the process that starts with FCY or something like that. Once you get past that it will ask you to plug in your phone and install the software.

HTC One, gCal synced to iCal (OSX Lion) with no issues. All dates show on either calendar.
However, neither gCal nor aCalendar on the HTC show dates before August when I bought the phone.
I removed my google acct completely. Restarted the phone and re-entered the google acct. No change.
It seems out of the 5 calendars I use, only one shows all older dates prior to Aug '13. 3 Other calendars show all older dates Oct '11 to present. And the primary calendar doesn't show prior to Aug '13.

I've been doing a bit of research, and it seems that Samsung Kies is not meant for (or supported) for North America. Apparently, the older versions of Kies could work on our Captivates and was available to download through Samsung's Europe site. However, the newer versions of Samsung Kies can apparently detect that we've got North American Captivates and will not connect. Anybody have links to the older versions? Doesn't proprietary-ness totally defeat the reason we bought androids in the first place?
