View 2 RepliesMy friend is after a new mobile and I pointed him towards the Desire HD & Desire (there's the only relevance). He is quite adamant about having a Dual Sim mobile. Anybody know anything about them? Benefits? Ones to look out for? I don't know anything about them, but he's come to me for geeky knowledge. He's having a look at these android ones:
Reach Tech (Xiamen) Co., LTD amongst a few others.
The other day i was thinking while flashing a rom onto my galaxy nexus and i thought Why thres no one only android that can be installed in all the mobile phones, i mean like when you install linux you can choose between a lot but it can be installed on every computer it adapts itself to the computer. Why can't it be done in android?, its because that will take a lot of space?

Any options through android apps or etc?
We are new to Android development. We have written small code which reads /dev/graphics/fb0 and sends frames to other application through network. We are successful if /dev/graphics/fb0 is available. But some android devices have fb0 and fb1(ex - Samsung Galaxy Grand - GT- I9082, Android version 4.2.2). luckly sending fb0 frames is sufficient to get required frames. We are not able to understand why fb1 exist and what is significance of the fb1. We also found few mobiles have fb0, fb1, ... , fb13. How to find which is main framebuffer?

Just add brief and simple details like:
Where you live.
Network carrier
What FW are you using (eg generic, t mobile,o2 etc)
This will then help other people to know when the update is ready for them instead of keep trying Sunday evening onwards to get it

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 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 2 Replies View RelatedI program and test using the Droid Incredible. The other day my friend downloaded my alpha version, which works flawlessly on the Incredible, but crashed on his Moto Droid. I just updated my app to use 2.1 api's instead of 1.6; maybe this will make a difference? I upped my min version requirements to 7. My question is how can you make sure your app works on all phones and not just the phone your are building and testing on? Is there a way to emulate a particular device?
View 3 Replies View RelatedI have read the Backward Compatibility Article, and I don't full understand how (or if I can) make a program backwards compatible if I want to use a class introduced in later versions.

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.
