Question

i’m developing an android application and i don’t know how to make it compatible with all the versions. In eclipse i select only one API level, and in androidManifest i tried to put minSdk and MaxSdk covering all the version, but it crashes on some OS with different version.
How can i make it compatible with all the versions? Can you help me?

Answer 1

I’d say that you’ll make life really hard for yourself by attempting to make your application work on antiquated Android versions (and by that I mean 1.5 and 1.6). As Sky mentioned, only target Android 2.1 and above.

Can you please specify what exception is being thrown when you attempt to run the application on a different version of the OS?

Here’s my application’s definition in the manifest.

<uses-sdk android:minSdkVersion="8" android:targetSdkVersion="10">

Defining it that way does not guarantee that your application will work on Froyo, Gingerbread and Gingerbread_MR1. Here’s an example, I can’t use requestSingleUpdate() from the LocationManager class in my application because it was only added in API level 9 (and I intend my application to work in API level 8!).

You need to ensure that you use functionality that is in API level 8 and below. Does that make sense?
