Just to reiterate -- there is really no reason not to build against the most
recent (2.0) SDK, as long as you test against the older ones. Use
android:targetSdkVersion to tell the system that you have developed against
the newer version so they will be able to turn off their various
compatibility features. There are numerous tricks you can do with Java to
use newer APIs if they exist while still working on older versions of the
platform. For example, this code will allow you to use the new
Service.onStartCommand() callback while still working on older versions of
the platform:
// This is the old onStart method that will be called on the pre-2.0
// platform. On 2.0 or later we override onStartCommand() so this
// method will not be called.
@Override
public void onStart(Intent intent, int startId) {
handleStart(intent, startId);
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
handleStart(intent, startId);
return START_STICKY;
}
void handleStart(Intent intent, int startId) {
// do work
Of course if you want to make things absolutely as simple as possible, the
approach of just developing against the 1.5 SDK and only dealing with later
platforms as test targets is probably it. This can be extremely limiting
however, since it makes it impossible to avoid compatibility modes like the
density scaling, or take advantage of any newer APIs (at least without just
raw use of reflection).
