I've shared the beginnings of a FindBugs plugin for Android:
https://bitbucket.org/joebowbeer/findbugsandroidplugin
To use: hg clone, mvn package, and copy the .jar to your FindBugs
plugin folder.
Currently, the plugin contains a single detector, which finds (non-
static) android.os.Handler inner classes that may leak memory.
Memory leaks are a recurring problem for long running processes. This
detector could, for example, replace the following debug code in the
Handler constructor:
if (FIND_POTENTIAL_LEAKS) {
final Class<? extends Handler> klass = getClass();
if ((klass.isAnonymousClass() || klass.isMemberClass() ||
klass.isLocalClass()) &&
(klass.getModifiers() & Modifier.STATIC) == 0) {
Log.w(TAG, "The following Handler class should be static or leaks
might occur: " +
klass.getCanonicalName());
}
}
Is anyone else writing custom detectors for Android apps? I think
that a handful, at least, that would be very useful.
