I did it like this: download FX File Explorer, go to your the .zip file, (will probably be in downloads) tap and hold until the file is marked, tap the three dots in the top right corner, then tap on rename, then remove the .zip and type: if its a texturepack .mcpack, if its a map/world .mcworld, if its an addon .mcaddon, then tap OK, then tap and hold on the file and click on the three dots in the top right corner again, then click open with and there you should see Minecraft as an option, just click that and it should open minecraft and start the import of the file, then just wait until its done and thats all. if you didn't understand something or something didn't work just let me know by replying :)
