When Lenovo TD30t installs software, why does it show that the file cannot be found in the current path after JAD is generated from JAR?
Here's the thing:

If the software developer can sign the developed software, he will provide two download methods:

1, a single jad download, and the installation path of the jar configured in it. At this time, there is no need to download jar (actually, it is also downloaded, just installed online). Why not provide cans? Because once the software is signed, it must be installed through jad, and the signed software does not need to pop up annoying tips every time you surf the Internet or read the SD card, which is more conducive to the promotion of user experience software.

2. As some mobile phones cannot be installed only by jad, signature software cannot be used. In order for users to install and use it, a link to download the universal version, that is, jar, is generally provided. This is the user downloading to the local area and then clicking Install. There is no jad, but annoying tips will appear when connecting to the Internet!

I hope my answer can solve everyone's problems.
