Android SDK build-tools directory. Then in the compilation. That's how my mistake was resolved.

Problem solved. The reason is that I wrote the environment variable android home as android sdk home, which caused android home to be found in it

··· sdk tools ant: 198 null this already tells what the problem is.

debug...Some debugs are automatically added when packing**. Therefore, the operation efficiency is relatively not so high.

If you're going to do a product launch... With release version.

If you create a program in Visual Studio. By default, no optimization is made.

The Program's Release configuration is fully optimizedVisual Studio projects have separate configurations for the release and debugging versions of the program, and Visual Studio will automatically create these configurations and set the appropriate default options and other settings. As the name suggests, the purpose of building a debug build is to be used for debugging. (Optimizations complicate debugging, and building a release is intended for the final distribution of the version:.)

The program's "debug" configuration is compiled with full symbolic debugging, because the relationship between the source and the generated instructions is more complex. Debugs can be generated in a separate pdb file and do not contain any symbolic debugs

If the name of your file is, just type ant in the command prompt.
