The APK editor is a pile of rubbish, and the scum can't open it. Most of today's apps have security measures. The editor only copies its program steps, but can't crack and restore confidential programs at the same time, so even if you sign a defective app, you can't open it. (don't understand? As the saying goes, there are many repairmen. Take bicycle repairers as an example. They can only mend tires and repair motorcycles and bicycles. Let him repair cars and trucks. He can't repair them. )
