Android :: Way To Use Features In 2.1 / 2.2 While Keeping A MinSDK Version To 3?
May 26, 2010
I have a project that is just using Android 1.5 for programming, but with the proliferation of other handsets and some cool features in Android 2.2, we'd like to support the features without losing support for 1.5 or forking a new code base. Is it possible to do with Android SDK?I do have some sense of the "ugly" way to do it, as in keeping the same code base but have a build system that builds different versions for the platforms and keep different Java files around that get added in our out of the build based on which version is selected. I'm hoping someone else has solved the problem based on the many versions of apps in the market that run on multiple Android versions.

I will try to modify native Camera package in Eclipse. So, I make Camera project in Eclipse and try to compile it. But, "Platform Eclair is a preview and requires application manifests to set minSdkVersion to 'Eclair'" error message is shown. Does it mean minSdkVersion information should be inclused in Camera manifests.xml file as "Eclair"? If there are anyone know this, please share your valuable information.

I am on my second handset and I am having so many problems with the phones I'm thinking of just giving up and trying to switch to a Samsung Galaxy S. I'm on the wretched Orange network and my phone has these problems:
- Non-working FM radio - it is static on every setting, although sometimes Radio 2 works(!) regardless of what headphones are plugged in.
- Alarm not working - It just doesn't go off if left overnight, even when turned on and with 2 alarms set.
- No internet via 3G - It gives no traffic, completely dead regardless of signal strength. It works via GSM and HSDPA.
- Randomly dropping calls.
- Randomly not able to send texts.
- People ring me and it goes randomly straight to answerphone.
- Erratic bluetooth, sometimes it works ok, other times it randomly disconnects from headset or car system.
It seems like almost every problem present on this forum, my phone has at once and it's driving me mad. Are these problems likely to be due to the horrible old ROM version that Orange runs (1.15.61.10)? They won't update it because it is too much work to stuff all of their crapware onto newer versions (solely designed to make you pay for things that are already available free, e.g. maps, ringtones etc). I dread to think how long it will be for Froyo on Orange. I am scared of updating the firmware incase it doesn't fix my problems and then I may not be able to get a replacement. Has anyone else used a replacement firmware to get rid of any of the above problems, or should I bite the bullet and go for a Samsung (I know it is cheaper built and doesn't have sense but at least it works right?). Does anyone know if the new "Black" handset on Orange runs the same firmware or has any updates? Also, that awesome Clock feature on Desire, with Alarm, Stopwatch, Timer, etc. Is that Android or Desire cos I'd hate to lose it by changing from HTC.

I was playing with adding Text to Speech to one of my applications and have been working with it using the Android 1.6 SDK. I was hoping to release the code such that it could be used on the earlier 1.5 OS since there are still quite a few of these around - and this is an upgrade. I realize that the TTS won't work on the 1.5 (at least not as I have it here), but I didn't want the app disappearing from the market for those devices. At any rate, after struggling for a while with this - a lot of trial and error - I came up with what now seems like a simple wrapper to allow for the backward compatibility. This was mostly taken from the Android blog entry http://android-developers.blogspot.com/2009/04/backward-Compatibility. so I'm not exactly breaking new ground. Also, I'm not using all of the TTS features, hence the short list of "wrapped" methods, expand at your leisure. I'm attaching it here for anyone to use and anyone to comment on if I have done something really stupid. I'll comment back if my testing uncovers anything untoward.

I used to be a C/C++ programmer before getting in to android. I am not sure how people maintain 2 versions of a program without using #ifdef preprocessor macros. Right now I am changing the package name in eclipse and changing the code manually, but this seems really inefficient. Can anybody suggest a good way of having 2 or more projects that share most of the code?

I'm planning on getting LockBot when I get my EVO and I was wondering, what's the difference between the free version and paid version. I basically want the Moto Droid lock screen on my EVO for the slide to toggle sound on/off feature due to the lack of an external switch on the EVO. Would I be best to get the paid version or will the free version do that?

This is sort of about task managers, and yet, not. I have an application I need to stay open (meebo) but Androids's task manager closes it sometimes. I have tried using task managers to keep enough memory free that Android won't kill Meebo, but it usually gets killed eventually anyway. Does anyone have an idea on how to keep it open? I am running 2.2.

Let me start off my saying I searched this topic before I posted. I am constantly closing apps with them being restarted and I'm not opening them like Music, alarm clock, Amazon mp3 store, moxier mail, etc. The only one I actually use from time to time is music but they open on there own. Is there an app or setting to change this?

We have an application that connects to a device and therefore needs to keep running in the background even when there are no Activities active. What is the recommended way to indicate that our application is still active and for it not to be killed automatically?

Ever since the last update Handcent keeps my phone awake, and subsequently kills the battery if I get a text message and don't get to it for a while. I have the pop-up set to not turn on the screen or even appear over the lock screen. I uninstalled for a while used chomp and stock, along with sms popup and neither caused similar behavior?

Does anyone know of a good organizer app for keeping track of your life? Appointments and such. I have the Jorte and I do like it but for some reason it is now linked to my Face book and puts in all my friends birthdays which I do NOT want in there and I can't seem to unlink it. But I would also still appreciate any recommendations so I can check them out to see if they work for me.

It seems like more and more mainstream retailers are making apps for the iPhone, whether it be Starbucks, Pizza Hut, UPS, etc. When do they start making these apps available to Android users. The Droid has sold almost 1,000,000 units in a little over a month. With several phones slated for 10' do you think that this will happen?

The default way configuration changes (i.e., rotates) are handled is to destroy the activity & recreate it with a new one. What is the recommended way to handle these changes in an activity that binds / unbinds to a service (that is possibly heavy/slow to start)? When the activity gets destroyed, it unbinds & causes the service to be destroyed. When the new activity is created, it binds & recreates the service.
The only choices seem to be:
-- override onConfigurationChanged in the activity. Feels ok, but non - conformant.
-- explicitly start the service & only stop it when the last activity gets an onDestroy that's not due to a config change (i.e., there was no call to onRetainNonConfigurationInstance). Feels icky.
-- explicitly start the service & don't stop it until some amount of time after the last unbind. Ickier.
On a related note, what happens between activity switches within a process, where the first activity (A) starts the next activity (B) & then calls finish() -- is there a guarantee that B.onCreate is called before A.onDestroy? If not, and the activities share a service, the same issue of keeping the service alive during this window exists, but with only the icky workarounds.

Is there a way to keep an Activity in memory after the user hits the back button on it?ActivitySearch is used frequently in my app, however after the user starts it up, then hits the back button, it's destroyed, and the next visit to it requires it be built from scratch again.If after its first construction, I could just request it be paused instead of destroyed on the back button, then I could reuse it. Is there a sensible way of doing this?The only way I could think of reasonably doing it is to combine ActivitySearch with ActivityMainMenu into a single activity, and simply switch views when the user chooses search, but this is probably a bad design.

When an app which uses the Map API is released it must be signed with the public cert. For individual use the key comes from the local debug keystore, created each time the Android SDK is installed. In other words, its different for each developer. When I include a view using it, then commit, my key goes in the xml, but the next developer to take an update clobbers his key, which being different to mine results in no maps being shown for him. Is there a smarter way to prevent this when a team is using the Maps API please?

I always see articles on places like Engadget about browsing stats and about how much traffic is from specific devices (or at least specific operating systems).It appears the Evo is showing up as running Mac OS and using Safari. I found that to be odd.

I have a map activity for which I would like to have the screen turned on as long it's active (the app consists of one activity only). When the activity is paused or stopped I want to return to normal on/off mode. Keeping the screen on works fine while the app is running but when I exit the app the screen stays on as well. What am I missing?

I've created an Android application which has a certain package name that I've been using personally for months now. I'm about to release it on the market, and I have to change the package name. This cannot be avoided.
My issue is that the application has an SQLite database attached to it that I want to keep, but I know if I change the package name, it'll install as a separate application and I'll have to restart my database, which would take a very long time.
Is there a good way to change a package name while maintaining the SQLite database? Or at least moving the database easily? This will just be for my own phone since it hasn't been released to the public yet.

Just got the incredible and I need an app that will help me with work because that's the main reason I got a smartphone. I use to use Google Apps spreadsheets to keep track of all my writers projects, but it seems that would be harder on the incredible. Basically I need something where I can know which client the project is for, which writers are working on it, a short description of the project, if it's done, been paid for, etc. Any app that could help me with this?

we already got a battery meter in android 4.2.2, and it can tell if something is keeping the phone awake.For example, it shows that the "Android OS" is keep the system awake for 10 hours, but it can not tell me which app is holding some wake locks or wakes the phone frequently.I also installed Better BatteryStats, under Kernel Wakelock, it shows that the gps_lock is holding for 10 hours, but also not related to any app.

Is there any way to keep my Outlook contacts in sync with Gmail's (and thereby my Android's)?
I've just tried Go Contact Sync, no luck.
or..
Is there a proper sync suite out there? I've purchased Mark/Space's Missing Sync - it's not working at all. The new HTC Sync 3.0 for 2.2 Android is not working either.

Anyone know of a simple organizer app to keep track of books that you've read? I used to have a group in my contacts called strangely "books" on my BB storm. In the notes section I could keep an unlimited amount of information. Now on my Fascinate the notes section is limited and unusable for my needs.

What is most efficient way of keeping a check on time within a game thread? Currently I create a new Date() when the game starts and was thinking of creating another Date() within the game thread and comparing it with the first one. But with a screen refreshing at around 60fps (hence a new date object each time), I can't help thinking this is rather inefficient. What other ways are there of doing this?

How does one create a graphics canvas that is visible by the user through orientation (port->land->port) changes? If one defines layout land and port, there is a noticeable pause during the switch. Yet, I downloaded a bubble level application that never pauses as orientation changes - even when it switches from a circular level (gravity vector through back of device) to a flat level (gravity vector through side or bottom edge).
