I have developed my app in android 2.2, and put it on google market (munspel-appen).
I could see in the statistics that 4% are using android version 2.1 i dont have access to such device, so I wonder if my app will still work on that older version device if downloaded from market too or is it only working from 2.2 and up? How can one tell?
The configuration of your app (https://play.google.com/store/apps/details?id=com.munspel.munspelappen) seems to limit the app to devices with 2.2 and higher.
Users with a lower OS Version then 2.2. can not download your app from google market.
I would test your App in an Android 2.1 Emulator and if it works there change the minSDK for your app to 2.1 and upload an update to the market. In that way your app will be available to as much users as possible.
you can try in the android emulator in eclipse for example
Your application may work for 2.1 version provided that your application is compatible with API Level 7.
Well you can specify android:minSdkVersion=8 in AndroidManifest, (from document)The Android system will prevent the user from installing the application if the system's API Level is lower than the value specified in this attribute, You can try running your application on Emulator running 2.1 version. read more http://developer.android.com/guide/topics/manifest/uses-sdk-element.html#uses
If you're willing to pay, there are several companies specializing in testing Android apps on physical devices. Examples:
http://duarlander.ning.com
http://www.perfectomobile.com
I think there's a lot more in google.
First, the Market should use the minSdkVersion in your Manifest to filter the apps when searched.
To test, you can use an emulator of version 2.1 and see whether it works.
Most probably most of the code will work except those new in 2.2.

I'm an iOS developer, but I recently developed an Android app for a customer, because they were unable to find a developer. So I made it and it works. But, I'm a complete newbie.
My customer says that their users complain than the app is not available for the newest versions of Android. I build the app against the latest version of the SDK. How do I make it compatible with new versions of Android?
The Play console lets you see thousands of devices in the app ecosystem, whether they are compatible with your app, and why. The help article gives more details.
I've been using google's fused location services on my app for location tracking. I use Android studio and it's gradle build system. Recently I have discovered a big issue with google's location services.
My gradle build file contained this dependency: compile 'com.google.android.gms:play-services:+. So when I rebuilt my project, Android studio downloaded the latest version for google play services, namely 5.2.08. HOWEVER my device (Samsung Galaxy S4) only has the 5.0.89 version. And apparently these two versions are not compatible, I get this error : Google Play services out of date. Requires 5208000 but found 5089038. I cannot update google play services on my device. It states that it is up to date (5.0.89).
Using this solution I managed to get the tracking system working, but it won't work on another device I own (a W8L device), which has another version of google play services: 5.0.84.
It seems this is not an uncommon thing to happen with google. How can I fix this for any devices out there, and make sure that google doesn't mess up my app.
Same thing is happening here, i solved by changing the play services version at gradle:
compile 'com.google.android.gms:play-services:5.0.89'
They probably released a new version but the roll out haven't arrived in our devices yet.
I just built and released an app on TestFlight. However, when I tried to download -> launch the app on my phone it crashes right away.
My DroidX details are:
System Version: 45.621.10.MB810.Verizon.en.US
Android Version: 2.3.4
Kernel Version: 2.6.32.9-g3e80c7a
Build Number: 4.5.1_57_DX9-10
I tested my app on simulator that had the details below:
Device: Nexus 4
Target: Android 4.3 - API Level 18
How can I troubleshoot further to see why my app is crashing? On ADB I don't see options for DroidX in Device and neither do I see option for 2.3.4 under Target.
I'm new and trying to figure out where to go from here to find out why my app is crashing on this phone?
It sounds like you've built the app using an API that isn't available on the Droid X. As you noted above, the X is at Android 2.3.4, and your simulator is at 4.3.
Check here for more information on setting the API in your app's manifest. Android 2.3 is API level 9.
Note, though, that if you downgrade the API your app is using, you won't be able to use features available in newer versions of Android. One of the most noticeable additions to Android since Gingerbread, for example, is the action bar.
If you do want to downgrade, you'll need to download and install the SDK for that API level to use it for development. The easiest way to do that is via the SDK Manager.
I have develop blackberry application using BB SDK 5.0 and tested it till 7.0 SDK and is run perfectly till 7.0.
I don't have the devices or simulator for 7.1 SDK, so is my application be able to run on 7.1 SDK also?
Thanks.
From my experience if you develop on SDK 5 it should run fine on anything above 5 (with the exception of 10 of course)
However, I would highly recommend you at least test on a simulator/device rather then just to assume all the functionality of your app will be there.
Please read the release notes for BB SDK 7.1. This document describes most (if not all) of the significant API changes.
You can also check binary compatibility of BB SDK 7.0 and 7.1 by comparing old and new versions of all SDK JARs by the japi-compliance-checker tool and check if changed particular API interfaces are used by your application.
I want to develop a Java app for Nokia N70 (S60 platform). Unfortunately, Nokia thinks this phone is way too old and nobody should develop for it. I once used the MIDP SDK 2.1 beta, is there something better?
For older devices, you can use the oracle javame sdk. The emulator is different. But basic apps will work on the device. Make sure you use midp2.0 and sometimes also cldc 1.0, otherwise app will not start on device.
In past I've been done something on S60 platform and SDK 2.1.
Unfortunately I think is the unique...
Moreover symbian will die soon so, make your accounts :)
