Android Marketって

To make it easier for developers to distribute and manage their products, we will introduce support for device targeting based on screen sizes and densities, as well as on GL texture compression formats. We are also increasing the maximum size for .apk files on Market to 50MB, to better support richer games.

今後、ファイルサイズ50MBをサポートするみたい。
そうだよね。そうじゃなきゃゲームとか困るよね。
「声で応援」フルサイズで出せるかも。
