Emacs uses JDEE to write Android programs

The previous section describes how to use Maven to build an Android project and how to use JDEE to write programs.

Ubuntu 14.04 Android uses Maven 2 to create its own Maven Project

For how to install JDEE, refer to the previous article:

Configure JDEE in Emacs 24.3

First, install an m2jdee plug-in to generate the prj. el file required by jdee Based on the configuration in maven pom. xml.

Obtain the project:

git clone git@gitlab.com:devtool/m2jdee.git

git clone https://gitlab.com/devtool/m2jdee.git

mvn install

  <pluginGroups>    <pluginGroup>org.freebird.maven.plugins</pluginGroup>  </pluginGroups>

mvn m2jdee:jdee

(jde-project-file-version "1.0")(jde-set-variables  '(jde-sourcepath '("/home/dean/work/gitlab_cloud/android/example/mvn_example1/src/test/java" "/home/dean/work/gitlab_cloud/android/example/mvn_example1/src" ))  '(jde-global-classpath '("/home/dean/.m2/repository/org/apache/httpcomponents/httpcore/4.0.1/httpcore-4.0.1.jar" "/home/dean/.m2/repository/org/apache/httpcomponents/httpclient/4.0.1/httpclient-4.0.1.jar" "/home/dean/.m2/repository/xerces/xmlParserAPIs/2.6.2/xmlParserAPIs-2.6.2.jar" "/home/dean/work/gitlab_cloud/android/example/mvn_example1/target/test-classes" "/home/dean/.m2/repository/commons-logging/commons-logging/1.1.1/commons-logging-1.1.1.jar" "/home/dean/work/gitlab_cloud/android/example/mvn_example1/target/classes" "/home/dean/.m2/repository/org/khronos/opengl-api/gl1.1-android-2.1_r1/opengl-api-gl1.1-android-2.1_r1.jar" "/home/dean/.m2/repository/com/google/android/android/4.1.1.4/android-4.1.1.4.jar" "/home/dean/.m2/repository/org/json/json/20080701/json-20080701.jar" "/home/dean/.m2/repository/xpp3/xpp3/1.1.4c/xpp3-1.1.4c.jar" "/home/dean/.m2/repository/commons-codec/commons-codec/1.3/commons-codec-1.3.jar" )))

C-c v.

The complete menu appears.

Configuration successful.

How to debug

First in ~ /. Emacs. d/init. el. Set jdb as the debugger and debug port as 8700.

;; jdee(add-to-list 'load-path "~/.emacs.d/jdee-2.4.1/lisp")(load "jde")(custom-set-variables '(jde-debugger (quote ("jdb"))) '(jde-db-option-connect-socket (quote (nil "8700"))))(require 'android-mode)(setq android-mode-sdk-dir "/opt/android-sdk-linux/")

Start

Andriod-start-emulator

Android-start-ddms

Be sure to select the process to be debugged in the DDM window

Commands used for debugging

Mvn_example1 $ jdb-sourcepath "/home/dean/work/gitlab_cloud/android/example/mvn_example1/src"-attach localhost: 8700 set javamvn_example1 $ jdb-sourcepath "/home/dean/work/gitlab_cloud/android/example/mvn_example1/src"-attach localhost: 8700 set not to capture java. lang. throwable sets the delayed uncaptured java. lang. throwable is initializing jdb .... lang. throwable sets the delayed uncaptured java. lang. throwable is initializing jdb...

The jdee jde-jdb-attach-via-socket command is as follows:

Jdb-connect com. sun. jdi. SocketAttach: port = 8700

Unable to connect to the jvm in android.

After the experiment, you need to add a parameter to connect:

Jdb-connect com. sun. jdi. SocketAttach: port = 8700, hostname = localhost

Therefore, modify the jdee configuration as follows in init. el:

;; jdee(add-to-list 'load-path "~/.emacs.d/jdee-2.4.1/lisp")(load "jde")(custom-set-variables '(jde-db-option-connect-socket (quote ("localhost" "8700"))) '(jde-debugger (quote ("jdb"))))
