I will be creating my first application and if I want it to be backwards compatible with Gingerbread (according to androidtapp.com/android-platform-stats-jelly-bean-nudges-ice-cream-sandwich-gingerbread-dips Gingerbread is still widely used). If I choose to build against API level for Jelly Bean, would it be backwards compatible? Or do I need to choose an API level for Gingerbread?

I can run my application on 1.5, 1.6 and 2.0 emulator and on a 1.5 device without any problems. But some of my users are reporting force close and strange menu entries (see the attachment) using 1.6 and higher version devices.
This screen should look like this:

Has anyone with a MyTouch/Magic tried any of the nesoid/snesoid/negsoid/gameboid emulators? Is there a way to get in touch with the developer to see if he's working on, or planning on working on, new versions to handle the lack of a keyboard?
View 4 Replies View RelatedI'm pretty new to Android, and I had some questions that I've had trouble getting answered via the web. I have done a few searches, but I'm not sure how to word my question, either. So I apologize if this has already been covered somewhere...but here it goes. I was wanting to know how the Android handles application versions/ updates. Specifically, does an update blow away my database? Is there a way to preserve the users' settings as well?

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?

View 2 Replies View RelatedThe requirement is totally simple: I want to have a lite and pro version of an app. There is a little bit of difference between those two apps, but they are 99% identically. Unfortunately it seems that the best choice is to really treat this as two projects that are one and the same and copy over the source code and assets from one to the other. The Android Manifest file must be different, because the Android Market - for some reason - makes the implementation's package name the ID. Working around this ID issue the straight forward approach would be to have a third project with the common code that exports its code, libraries and in a best case scenario also the ressources to the other two objects. Unfortunately this doesn't work. Only the actual Android projects generate the R.class and so the common project would need to be dependent on it..
View 6 Replies View RelatedI'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 11 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.

View 14 Replies View RelatedYou can no longer send the ACTION_ATTACH_DATA intent with an image URI to a custom content provider without crashing the Gallery app. This bug was reported more than a month ago. 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.

View 6 Replies View RelatedWe are upgrading our application to add 2.0 support. I have read http://developer.android.com/guide/appendix/api-levels.html and the older blog post http://android-developers.blogspot.com/2009/04/backward-compatibility.... I want to avoid using reflection if possible. I have found that if I set my minSdkVersion="3" in the application manifest but in my build path in eclipse point to the Adroid 2.0 jar file I can compile with direct calls to 2.0 code (with the relevant code to ensure they are not invoked on <2.0 devices). My question is will people with pre 2.0 devices be able to see the application in the market place in this case? What are other people using for multi-targeting different API levels with the same package.
View 7 Replies View RelatedI am planning to have two versions of the same app available in the market - let's say "App-Lite" and "App-Advanced". They both almost the same core functionality, but App-Advanced has a bit more specific features, than the App-Lite has. Now I am thinking what would be the strategy of deploying those two apps in the market. The simple way is to provide different name space in AndroidManifest.xml for both apps, so "App-Lite" and "App-Advanced" would show up as two completely different applications and could be installed parallel on the same device. But I'm also thinking about another way of installing the App-Advanced version - like an upgrade to the App-Lite which might be already installed. To do this, I can just set the same name space for both app in AndroidManifest.xml, so after installing one app would replace the other one - I can do this from adb command line, but I'm not sure how android market would behave in this case. Will it show them as two different apps, will it show them as two different versions of the same app with the ability to upgrade from one version to another, or it just will not allow to publish two apps with the same name space? Is this scenario doable with Android Market?
