I experience this problem when I added another project from internet. I think it asks me to use another version of target android. But I want that my app will work in android 2.2.
But it doesn't require API-8, it requires API-16 and I m not sure what I should do.
Modify the AndroidManifest.xml file so that any versions in there are Android 2.2. Also change the version of the SDK used by right clicking the project in eclipse and go to properties->android and change the version to 2.2. Some things might break though. Usually the version declared in the manifest is declared because the project uses SDK features only available for that version or later.
Your app will still work on older versions even if you are targeting newer version. The target is what version you have tested your app to work on. If you target the most recent version (API 16), then your app will not be put in 'compatibility mode' when running on older phones. For example, if you have a menu button in 2.x but you target API 16, this menu button will not show up on certain phones since you're supposed to be using the ActionBar.
The minSdkVersion is what you are thinking of, which will make sure your app runs on older versions:
<uses-sdk android:minSdkVersion="8" />
So the solution to your problem is just to download the newest API level through the SDK Manager. You most likely just don't have API 16 installed.

I have just downloaded the latest SDK version from Android SDK Manager and set my App's Project Build Target to Google APIs level 17 as below
And added in my App's AndroidManifest.xml as below
<uses-sdk
android:minSdkVersion="3"
android:targetSdkVersion="17"
android:maxSdkVersion="17" />
And loaded the Emulator with Level 8, 2.2 then tried to launch the App on this Emulator. Whenever I run the app it says "No compatible targets were found" (I know I can create AVD for level 17 but want to launch on emulator level 8) when I have android:minSdkVersion="3" in my AndroidManifest.xml.
I researched a lot and did not find a proper answer to this.
Then I changed the Project Build Target to Android 4.2 level 17 as below
The App started launching on all the Emulators below level 17.
But I still don't know what is restricting the App to launch on lower version Emulator when the Project Build Target is to Google APIs level 17
Google APIs Add-On is an extension to the Android SDK development environment that lets you develop applications for devices that include Google's set of custom applications, libraries, and services. A central feature of the add-on is the Maps external library, which lets you add powerful mapping capabilities to your Android application.
Enabling Google APIs lets you use features that are not present in default Android devices. Since your minSdkVersion is set to 3, you should be able to launch the application if you create an emulator with API version greater than 3 but with Google APIs enabled.
Just remove the targetSDKVersion attribute and then try.
An integer designating the API Level that the application is targetting.
With this attribute set, the application says that it is able to run on older versions (down to minSdkVersion), but was explicitly tested to work with the version specified here. Specifying this target version allows the platform to disable compatibility settings that are not required for the target version (which may otherwise be turned on in order to maintain forward-compatibility) or enable newer features that are not available to older applications. This does not mean that you can program different features for different versions of the platform—it simply informs the platform that you have tested against the target version and the platform should not perform any extra work to maintain forward-compatibility with the target version.

try removing android:maxSdkVersion
if i use android 4.1.2 (API 16) Android SDK will my apps work on Android 2.3 phones. i have downloaded android 4.1.2 sdk tools and other packages.
You will need to set the minimum SDK attribute in your manifest to 2.3 to ensure you app will work on earlier versions of the OS.
Your app will work fine, assuming you are not using any API calls from a later version.
The Android Dev team suggests you always compile against the newest version you can support. So, you are on the right track.
So bottom line, you are on the right track, just make sure to test your app against a 2.3.3 version of the emulator to ensure you are not using any un-supported API calls.
No, if your minimum sdk version is 16 it wont work on that android version.
if you want it to work on that specific version then set the minimum sdk version to 9. You can change this in the apps manifest file.
<uses-sdk
android:minSdkVersion="9"
android:targetSdkVersion="21"
/>
If you are getting errors probably saying "This code uses the minimum sdk to be api 16 or higher"
find alternate ways to modify the code for older android phones. If that does not work then dont support old version of android maybe.
I set up my project to use Android 3.2 (API Level 12), but it seems like a lot of phones are still using Android 2.2 (API Level 8).
Is there a way to change my project from only supporting Android 3.2+ to supporting back to Android 2.2?
yes...just change the minsdk number in the manifest. You have to be sure that you don't use any feature that is not supported though...
in your AndroidManifest.xml add this line:
<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="16" />
android:minSdkVersion tells the Store what the minimum version you are targeting is. In this case 2.2. Devices less than 2.2 won't be able to download your app.
android:targetSdkVersion tells the store what the best version you are developing for is. In this case 4.1. Devices over 4.1 can still download your app but certain features may run in compatibility mode.
NOTE: When you setup your project to use 3.2, all you did was select the Android SDK you wanted your IDE to use when checking and compiling your code. Without the uses-sdk line in your manifest you've targeted nothing.
Right Click Project -> Properties -> Android -> Select SDK version
Update Manifest, min/target api. (as others have described by others).
Go to your Manifest.xml file and edit the minSdkVersion to 4. That will set it way back to 1.5 or something like that :). You can make that number higher if you want to suit a higher API, but I like compatibility.
I'm working on an application which uses ActionBarSherlock. As it's documentation points out:
[...] the library requires that both it and your project are
compiled with Android 4.0 or newer. The project also requires that
you are compiling with JDK 1.6 in both your editor and any build
systems that you may be using.
So, that means I'll compile my application (and the library) against Android 4.X but in my Manifest, I declare that I'm targeting (e.g.) API Level 9.
This all works fine and well but there is something that disturbs me. From the FAQ:
What API level should I target in my manifest when using the library?
Targetting API level 11 or newer is required as it will cause Android
to automatically add the native action bar when run on newer devices.
Since you will be compiling against new APIs but your app will likely
be run on devices with older versions of Android extra care must be
taken to either avoid using or properly check and call any methods
that were introduced after your minimum SDK version.
That means, that I'll have to manually check every method call, so I don't use any that are not available in my targeted API Level (9 in my case)? This sounds wrong to me.
Is there a way to tell my IDE (IntelliJ), that I'm only using the API Level 9 (so I don't get any auto-completion for non-existing methods/classes and don't use them by accident) and then choose to compile it against another Android version?
Or can I use some automated checks (which run at compile time) to check for that?
The ADT's lint feature should take care of this by warning when API calls are being made for the wrong API version.
You should be compiling both ABS and your project with the latest SDK available (at present, 4.1). Your manifest should have a targetSdkVersion as high as possible (ideally matching your compilation SDK) and your minSdkVersion should be set to the lowest version you support.
Lint is partially integrated with IntelliJ IDEA and is also available as a command line tool.
You temporarily set your target SDK to the various lower ones and debug with it. Your final build then is with the latest SDK.
Set a Build target similar to that you have mentioned in your manifest.
as always , you should set the targetSdk to the maximum available on both the manifest and the project.properties file (as recommended by google on one of their videos) , so that the ADT&SDK would be able to optimize the ADK accordingly.
set the minSdk to the one that you wish to support your app from , and let Lint to tell you if there are any problems in case you use too-new-features.
I've built an Android application in eclipse. Before starting the project I selected the 2.3.3 api. The code is very basic.
A friend of mine asked to have a copy, but he's using 2.2, do I have to rebuild the project in 2.2 or will it work just fine if I send him the APK build with the 2.3.3 api?
change
<uses-sdk android:minSdkVersion=.... />
in the android manifest to
<uses-sdk android:minSdkVersion="8" />
Change the Project Build Target to 2.2, in the Properties Menu of your project in the Android drill down.
You should only get errors if you used methods that were introduced with the level 10 API (Android 2.3.3). Since you pointed out that your application is very basic, I highly doubt you'll run into major problems.
From the docs
Selecting a platform version and API Level
When you are developing your application, you will need to choose the platform version against which you will compile the application. In general, you should compile your application against the lowest possible version of the platform that your application can support.
You can determine the lowest possible platform version by compiling the application against successively lower build targets. After you determine the lowest version, you should create an AVD using the corresponding platform version (and API Level) and fully test your application. Make sure to declare a android:minSdkVersion attribute in the application's manifest and set its value to the API Level of the platform version.
So in short, you'll have to recompile it
If you go to the properties for your project and then select the Android dialog, you can change the API which your project is using. Provided you have have it installed.
In the AndroidManifest file set android:minSdkVersion to 7. In this way you force it to run in compatibility mode on devices that have lower version than the target mode(which is 8 in your case).
