If I build against the 1.5_r3 SDK are there any compatibility issues with running it on devices that are at previous levels of 1.5? I would certainly hope not, but I've learned not to make such assumptions.

I recently enabled the app2sd functionality in my app.When i test the apk on my NexusOne (2.2) the app goes to the SD card, perfect! But when i publish the app on the market and install the same apk from the market on the same Nexus, the app2sd function is missing, I can't install it to my SD card.

View 8 Replies View RelatedI am trying to cache my viewgroup to a bitmap and blit this to screen instead of calling dispatchDraw on the group while scrolling for performance reasons. This works quite well on 1.5, but has ugly scaling artefacts on 1.6 and newer for high density screens. Because of my 1.5 compatibility I can't find a way to set the density of my cached bitmap.
View 2 Replies View RelatedI would like to know whether the Android provides any sort of compatibility i.e either forward or backward. It means as in Blackberry if develop an Application with JDE 4.2 then that application will work on any handset with OS 4.2 or higher which means it has forward compatibility. Is there anything similar in Android? Suppose I develop application with Android SDK 1.5 then will that application work on any handset having OS 1.5 or higher.
View 1 Replies View RelatedI'm having trouble getting my app to work properly on older devices. I've ready the "Backward Compatibility" tutorial, I'm working for performance - and it suggestions using .invoke is considerably slower than using a wrapper class. But it seems the wrapper class only works for if a class is not available on older devices. I'm compiling with 2.2, but minSDK is 1.5. I'm working with multitouch, I assumed that if I checked against Build.Version.SDK, and didn't call getPointerCount() - then it wouldn't raise an error. But when I create an instance of the class which has my methods in, I get this: 06-29 08:17:28.263: ERROR/dalvikvm(255): Could not find method android.view.MotionEvent.getPointerCount, referenced from method com.myPackage.myClass. Despite not actually calling it. Is this normal?
View 1 Replies View RelatedI don't know why, but in Eclair, the default (non-fancy) gallery app changed its behavior from the Cupcake version, and it broke one of my commercial applications Firstly, when long-pressing a gallery and choosing "Diashow", it does not publish an Intent to be picked up by any application that implements the Intent filter anymore. Instead, it will directly call "com.android.gallery/com.android.camera.ViewImage" with extras. Question: is it still possible to intercept this intent and allow the user to choose my application to do the Diashow? Secondly, the intent extras for the VIEW intent are messed up (in my build of 2.1 anyway): Instead of providing the BucketId of the picture in the Intent's query parameter. But in 2.1, the BucketId is moved to the Intent's extras. Except; it is not passing the BUCKET_ID, but the unlocalized BUCKET_DISPLAY_NAME instead Question: how can I still get the unique BUCKET_ID from the intent, so that I do not have to work with a potentially non-unique BUCKET_DISPLAY_NAME.

Everything is good up till now, but when I press back, effectively calling webView.goBack(), the webView loads the failUrl I passed to loadDataWithBaseURL. Why does it work going forward, but not going backward?

There are a few threads of various Vibrant/TouchWiz Calendar issues (Samsung Galaxy S). I am starting this thread to hopefully get a reply of all the various issues in one spot and maybe someone can get this list somewhere that will drive change. In my mind, a smart-phone's roots is a PDA + Phone. Yes, it is amazing that they can do much, much more now, which makes these phones that much better, but to me, the Calendar is part of their roots. These disappointments that I'm starting with were available in Android 1.5 which makes them all the more frustrating. I am bulleting these instead of numbering them because I'd rank them all at the top. Really, any issue that you are having out there, especially one that is a non-issue in stock Android, is pure neglect by Samsung.
- No ability to customize notifications in the TouchWiz Calendar. Anyone need a reminder ringtone that is different than your other notifications? You won't get one that stands out from the others in your Samsung Vibrant because you have no ability to change it.
-No ability to hyperlink in the TouchWiz Calendar. Let's say I am going to a wedding that is out of town. On my G1 I could enter phone numbers and address to the Hotel, Reception Hall, key contacts, and the like; so all I had to do was go to my trusty calendar and click on a hyperlink to get directions in my map or call people/places via the dialer, oh, and I'd know what time things started because it is a super useful feature in a calendar. Good luck doing this conveniently on the Vibrant's TouchWiz Calendar because it does not have this feature. Maybe the biggest disappointment.
-Repeating Events in the TouchWiz Calendar provokes issues when modifying . If I edit only a single event in a series of repeating events via my web-browser on my laptop, TouchWiz will duplicate the event, keeping the original event, but also creating the changed single event as a new separate event entirely.
I'm sure this is the tip of the iceberg because I've seen a number of posts. . . although I haven't seen any mention of the hyperlinking which I find an enormous help.opefully someone from T-Mobile or Samsung will review and implement asap. In the end, I may return my phone if I have no confidence in these being fixedI'd also love to hear solutions. I've tried all the market calendar apps I could. Gemini, Junte, they provide hyperlinking, but don't fix the duplicatation issue. All other calendar apps ultimately just click through to the native Touchwiz calendar.Given the specs on the current phones out there, these features should be included off the shelf. I've rooted my G1, but one shouldn't have to root to have basic features available to Android such as the above.
<supports-screens android:anyDensity="false" android:largeScreens="false" android:normalScreens="true" android:smallScreens="false" android:resizeable="false"></supports- screens>
first of all what is the resizeable attribute? It does not seem to be documented. This is working almost 90% for my game except when testing in WVGA screen resolution, all my images are scaled incorrectly, it is longer vertically than horizontally. I was expecting the screen compatibility to maintain aspect ratios as that of HVGA.
Also in my layout I have a scrollview and it is designed in such a way that in HVGA when it is not scrolled down, the items are hidden away, however now in WVGA those things are shown. If the aspect ratio of HVGA is maintained I won't have this issue. How can I make sure the aspect ratio is maintained? Also in my layout I am positioning some items using pixel positions. Should I convert these to dpi? How do I calculate what dpi they should be?
What is the recommended approach to have currently shipping 1.5-SDK compliant apps to start offering 1.6 features (such as TTL) in the Market? Can we just publish 2 versions of the same package name each compiled with a different SDK level (will the Market automatically push out only the right version of the app) or do we have to use different package name and assume that the user will find a way to understand the version of the OS he has. A public statement to the developper community would be more than welcomed here!
View 5 Replies View RelatedI've found again my DevPhone1 (aka G1) on a shelf and though that this time I should really give it a try and create an app for it. But I've really lost touch with the Android world and now I don't know where to start really. There have been many SDK releases lately for many new and better devices. Which one of these can I use with G1? What is the most recent one which can be used on that hardware (although with reduced performance) but which will enable development for rather modern Android releases as well. The firmware update received today, while recharging the phone, is 1.6. Can I go higher with some R&D build?

I've got a question as I don't have an Android 2.0 device to test on and this particular aspect seems untestable in the emulator. I've got a service that needs to be run as a foreground service. I have a notification that stops it etc, so I have no problem using startForeground instead of setForeground. However, I'd like to have 1 version of my app that works across all platforms... Is this possible? If my app is compiled with Android 1.5 and uses setForeground, then will that command actually work on an Android 2.0 device, or does it not matter which sdk was used to compile? I've tried compiling with 2.0, and surrounding the call to startForeground with a try/catch, but that throws a VerifyError when the service is started, when run on a 1.5/6 device since startForeground doesn't exist there. Can I catch and ignore the VerifyError somehow and make it work that way?
View 5 Replies View RelatedI have an app that uses People provider. This is deprecated in version 2.0. I have built my application against API1.6 and set <uses-sdk android:minSdkVersion="4" android:targetSdkVersion="4" /> Everything was fine until I wanted to run the app on Android 2.0. Not only is People deprecated it actually doesn't even work! So, I have changed the API I'm compiling against API2.0 and do the OS version check in my code and use People provider or ContactsContract accordingly. I still keep <uses-sdk android:minSdkVersion="4" android:targetSdkVersion="4" /> so I can target 1.6 devices. Now when I want to debug in Eclipse it insists on running it on 2.0 emulator. How can I tell Eclipse that I really want to debug on 1.6 emulator? I have installed my APK on 1.6 emulator via the browser. It installed fine, but when I want to use People provider it crashes. I need to be able to debug it.

It is a stupid bug that is super easy to fix, and as soon as Froyo was open sourced a patch was submitted. Still Froyo was officially released and the bug remains leaving developers who use this with an app that is no longer compatible and no easy way to work around it for 2.2. There are other bugs that also have not been acknowledged. This 'open' thing is great but it is not of much use this way.
