Can some one tell me why my apk is not compiling i have checked the codes many times but its not not comiling

Question

I want to mod a game and I have completed it, but now it is not compiling even if I had tried by recompiling its original decompiled apk, but its not working.

Can someone help me out?

it says:

D:\MOD\APK_Toolkit_by_0xd00d\1 - Decompiled\mini militia hacked (R&Y)_4.2.8.apk\res\mipmap-anydpi-v26\icon.xml:1:error:not well -formed(invalid token)

and in second line it says:

unable to open D:\mod\APK-Toolkit_by-0xd00dz\2 - compiled\mini militia hacked (R&Y)_4.2.8.apk'as zip archive

I am new and I want someone to guide me what to do next.
