Dare: Installation and usage
Files are available for Linux and Mac OS. They were compiled on Ubuntu 11.04 and Mac OS 10.6. If you have any question, please use the Dare support mailing list. Dare is released under the GPL; instructions to download the source and build it are available at the source page. For your convenience, Soot is included in the Dare archive. It can be used to optimize and/or decompile the output of Dare.
Installation of Dare (retargeting .dex/.apk to .class)
Dare requires a Java runtime environment version 1.6 or 1.7 (Dare has not been tested with Java 1.5). In order to install Dare, you need to download the latest version:
Additionally, if you are running a 64-bit version of Linux, you also need to install the ia32-libs libraries. This is not required on Mac OS. On Ubuntu, this is done with:
% sudo apt-get install ia32-libs
Then you need to extract the archive. After this is done, if you are using the Linux version, you should follow these instructions:
% cd dare-1.1.0-linux % ./dex-preopt --bootstrap
This will optimize the bootstrap classes to allow for the preverification step. Please note that the preverification is not currently supported on the Mac OS version.
Usage of Dare
Dare is used with:
% dare [options] -d <output dir> <dex/apk file>
Valid options are:
One of the important features of Dare is the ability to rewrite unverifiable Dalvik code to make it verifiable. The rewrites mimic the runtime behavior of the VM to ensure that the semantics of the program are not modified. This new feature uses a modified version of the Dalvik VM to verify the input bytecode. Unfortunately, this option is not currently supported on the Mac OS version of Dare.
