An APK compiled for Android 1.0 uses resources only. There were no drawable-hdpi , -xhdpi , or -night folders. If you decompile an Android 1.0 APK using apktool , you will see XML tags that do not exist anymore, such as spinnerMode="dropdown" (now default) and layout_gravity="top" (now replaced by constraints). Conclusion: The Ghost in the Machine Searching for an Android 1.0 APK is not about utility—it is about legacy. You will not download a single file to side-load onto your current phone. Instead, you will find system.img files, OTA update zips for the HTC Dream, and SDK archives.
