Reduce Import Size

[mikebevz]

I know it might be to early to request this but it would be great to think about reducing the size of the jars that have to be imported.
5+Mb now it's too much imho.

I'm not sure what it ends up being if properly ProGuard-ed (maybe that should be documented, or is it, I couldn't find it?), but I agree, 5+MB of libs for a mobile app is way too heavy.

Hello @mikebevz @charlieCollins,

The package size of SQLCipher for Android is mainly attributed to usage of both ICU along with other various Android dependencies. Much of this allows for portability across Android platform versions 2.1 - 4.4 currently. We will take this feedback however when considering work for the library in the future. Thanks!

The size (about 7mb increase) is really unacceptable on mobile device. The size almost doubled after include this library.... Thanks for the great work, but the size remain as biggest issue as a android lib.

Please reduce the library size..
The size is 7.1 MB.
I don't need to support api<15.
For Api<11 this library uses many codes and libraries.
Which is full of garbage to me.
Please remove the garbage codes and libraries which is used to support api <15.
Or make a library again which will support API >= 15
