Let's setup IDA so that we can start looking through the MCPE code.

After you have downloaded this, grab MCPE's library from an apk:
- Extract the apk using Winrar or 7-zip. If all else fails just open the apk as a zip
- Navigate to lib/armeabi-v7a, and extract the file libminecraftpe.so from here.
After you install and open IDA, you will see this window:
Untick "Display at startup". Now select Go. When you come to the main window, drag and drop libminecraftpe.so into the window. You will get this dialog:
Click the drop down menu that reads "MetaPC (disassemble all opcodes) [metapc]". Select the option "ARM Little-endian [ARM]", then click the "Set" button. Click "OK".

Now wait a few minutes for IDA to parse the executable. The amount of time this takes depends on the speed of your computer. The output at the bottom will notify you on completion:
First thing's first, let's switch to graph mode since it's easier to read. Click anywhere inside the assembly window and press the space bar. You should switch to a view that looks like this:
Let's also click the label on the functions window to sort the names of the functions in alphabetical order.
