Analyze Oom with MatMany oom seems to occur when bitmap is allocated, but it is generally not rootcause. The root cause is that the resources that should be freed automatically, because of code errors, cause some objects to always be referenced (Reference), such as Android memory optimizer, how to avoid mcontext references to the activity mentioned in the Oom article.When the code is very large, it is difficult to find errors by reading code alone, so
Collect and organize Android tool SystemUtils (continuous update)
Recently, some system-related things have been involved in the functions, and a tool class has been collected and compiled on the Internet for convenient calling.

Ant is a Java-based build tool, similar to make in (Unix) C. Unlike the extension mode based on shell commands, Ant is extended using Java classes, you do not have to write shell commands. Ant is a process script engine used to automatically call programs to compile, package, and test projects. In addition to Java, the script format is based on XML (default: build. xml), which is easier to maintain than make scripts.

, how do I get initial/intermediate testers and even developers to formalize Android app testing?The black box test method is the most current test mode for mobile testing. This means that manual testing will run through the entire software release cycle. But there are some problems with manual testing: it slows down the development process considerably, leaving a lot of room for errors, and ultimately reducing the team's confidence in releasing high-
