The application framework is a reusable design component. It specifies the architecture of the application, clarifies the dependency relationship, responsibility allocation and control flow among the whole design, collaboration components. JAVA mobile application program. In order to deepen the readers' understanding of JAVA, this paper first introduces the technology, and develops a practical application for JAVA mobile application development. The registration mechanism is used to verify the validity. The problem is solved by an ant colony optimization algorithm. First, using state, decision making, and patterning of problems, it is easy to use ACO to solve. Research shows that the algorithm determines the stack allocation object by analyzing the Java source code at the compile stage, and identifies these objects with extension instructions. When the program runs, they will be directly assigned to Java. These objects are automatically added when the program leaves its scope. Released, other Java objects are still allocated to the heap and are recycled by the garbage collector.
