Android Optimizer clears invalid code ucdetector

Android under optimization clears invalid unused code Ucdetector

official: http://www.ucdetector.org/index.html

Ucdetector is an eclipse tool that can review unused, redundant, variable-spec code in a program

Need to note:

Reflection , configuration injection in XML , application of third-party engineering, JAR-package invocation, etc. need to be judged by hand

We recommend that you delete the class by searching globally to see if there are other places calling Eclipse Global Search shortcut keys (windows:ctrl+g , mac:control+g)

The version I'm using is Org.ucdetector_1.10.0.jar

(i) Installation

Place the downloaded jar package in the Eclipse folder under the \eclipse\dropins folder, then restart Eclipse

:

(ii) operational use

Open Eclipse after installation is complete

The operation flow is as follows: Right click project → select ucdetector→ Select Detect unnecessary code and wait to run

(It may be a bit long if the project is relatively large)

:

(iii) operational results

Reports that run the results are generated in the workspace folder ucdetector_reports of the current eclipse open

There will be 2 files in the Ucdetector_reports folder

The results of the operation are also shown in Eclipse's problem.

:

(iv) Screening

To make it easy to find the filter categories for the results in problem

Select inverted triangle → pop-up window →group By→type

:

(v) Optimization

Follow the prompts to find the corresponding class to delete

For example, in the class baseactivity

:

Double-click the entry in the problem to enter the appropriate class:

(vi) Closure

plug-in use to note :

Reflection , configuration injection in XML , application of third-party engineering, JAR-package invocation, etc. need to be judged by hand

We recommend that you delete the class by searching globally to see if there are other places calling Eclipse Global Search shortcut keys (windows:ctrl+g , mac:control+g)
