One of the recurring problems in test-priority programming (Test-first programming) is that it seems impossible to automate many parts of a program. Especially when the program is to a large extent to take advantage of external resources and libraries, it seems difficult to test it, because there is no good way to simulate the program and the external resources of the connection. However, although it is difficult to test such a program with only Java code, there is one type of program

These three Android private libraries have been overwhelmed by these problems over the past few days. At last, we know that we should keep these three items. If there are other redundant packages, check whether there are repeated packages, or add the libs jar packageTo build path. The following is a detailed description. Recently, a colleague complained to me about the classnotfoundexception error that will

If these are not set, problems such as failure to parse a class or noclassdeffounderror may occur. Therefore, we must use eclipse to specify these paths to tell the Java Development and runtim
