As Android 40 2.1 includes key bug fixes and improvements not present in 2.0/2.0.1, only 41 Android 2.1 should be used for new devices. As there is no compatibility 42 program for 2.0 or 2.0.1, the officially compatible Eclair-based release is Android 43 2.1. (The linked document refers to Android 2.0, because there were 44 no new platform features added in 2.1.) 45 46 ## [Android 1.6](http://developer.android.com/sdk/android-1.6-highlights.html) ## 47 48 Android 1.6 corresponded to the "Donut" milestone branch, and has an API level of 4. 49 50 ## [Android 1.5](http://developer.android.com/sdk/android-1.5-highlights.html) ## 51 52 Android 1.5 corresponded to the "Cupcake" milestone branch, and has an API 53 level of 3. 54 55 ## [Android 1.1](http://developer.android.com/sdk/android-1.1.html) ## 56 57 Android 1.1 has an API level of 2. Android 1.1 was known as 58 "Petit Four" internally, though this name was not used officially. 59 60 ## Android 1.0 ## 61 62 was the first release of Android, and has an API 63 level of 1. Since it was the first released version of Android, no platform 64 highlights were prepared for this release. 65 66
