Ask for a tutorial, how to crack the SMS charge for Android games?

First, run the original game. After SMS is activated, lbe or 360 will remind you to send SMS to106xxxxx, write down this number, and then start looking for this number.

The first step is to open apk with WINRAR (actually, apk is a compressed file) and extract classes.dex from it to a folder.

Step 2: Download the decompiler tool xtemp (note that xtemp needs to install java environment variables. There are tutorials online). Open classes.dex with dex after downloading. Just press 1 in the pop-up interface, and you will see more classes folders in xtemp folder.

Step 3, download Notepad++Portable, run it to open the classes folder, search for the number you wrote down, or the first few digits of the number, and change it to 10086 or 100 10 or 10000 (depending on your operator) and save it.

Step 4: drag the classes folder to dex, and then press 2 in the pop-up interface. You will find that there are more out.dex files in xtemp folder. Put it back to the original apk and rename the class.

Step 5: The original signature is no longer available, so you need to download the apk signature tool apktool to re-sign.

Step 6: Before installing the modified apk, uninstall the previous version files, etc., and the installation is successful.
