问题 I'm developing an Android application targeting 2.x and 3.0 devices and thus I'm using the compatibilty API. I'm testing on Android 2.0.

(cursor.getCount() is 5 instead of 2) I have stepped through each iteration of the while loop and it is retreving the same contact multiple times, but with different values for POSTCODE , such as the phone number ContentResolver cr = getContentResolver(); Cursor cursor

问题 My simple audio streaming app works perfectly in 1.6 and 2.1 does not work in 2.2. I have no clue as to why.

问题 For my app, Transdroid, I am connecting to remote servers via HTTP and optionally securely via HTTPS. For these HTTPS connections with the HttpClient I am using a custom SSL socket factory implementation to make sure self-signed certificates are working. Basically, I accept everything and ignore every checking of any certificate. This has been working fine for some time now, but it no longer work for Android 2.2 FroYo. When trying to connect, it will return an exception: java.io.IOException:
