I wish to use jsoup library in Android Open Source Project. For this I did two things:-
Step 1:
[android]prebuilts/misc/common/jsoup/
Android.mk
{as it is name and code below:} LOCAL_PATH:= $(call my-dir) include $(CLEAR_VARS) LOCAL_MODULE:= jsoup LOCAL_MODULE_TAGS:= optional LOCAL_SRC_FILES:= jsoup-1.13.1.jar LOCAL_MODULE_CLASS:= JAVA_LIBRARIES LOCAL_MODULE_SUFFIX:= $(COMMON_JAVA_PACKAGE_SUFFIX) LOCAL_DEX_PREOPT:= false include $(BUILD_PREBUILT)
Step 2:
Problem:
import org.jsoup.Jsoup; import org.jsoup.nodes.Document; import org.jsoup.select.Elements;
frameworks/base/services/core/java/com/android/server/am/sample.java:48: error: package org.jsoup does not exist frameworks/base/services/core/java/com/android/server/am/sample.java:49: error: package org.jsoup.nodes does not exist frameworks/base/services/core/java/com/android/server/am/sample.java:50: error: package org.jsoup.select does not exist
Please, I have no idea of including external jar files in AOSP. The code works fine locally in IntelliJ IDE Java otherwise. Any help is deeply appreciated. Thanks in advance.
You can base your solution on some other jar already added in AOSP.
For example see ZXING library's Android.bp in external/zxing/
:
java_import { name: "zxing-core-1.7", host_supported: true, installable: false, jars: ["core.jar"], }
Then see the usage on another Makefile ::
LOCAL_STATIC_JAVA_LIBRARIES:= \ androidx-constraintlayout_constraintlayout-solver \ androidx.lifecycle_lifecycle-runtime \ androidx.lifecycle_lifecycle-extensions \ guava \ jsr305 \ carsettings-contextual-card-protos-lite \ carsettings-log-bridge-protos-lite \ carsettings-logtags \ statslog-settings \ zxing-core-1.7
Lastly, based on the path of the file you're adding frameworks/base/services/core/java/com/android/server/am/sample.java
, you're adding the library to the wrong makefile.
The one you changed ( frameworks/base/Android.mk
) is for making framework.jar
, whereas you're trying to add a class on services.jar
The correct makefile to modify would be: frameworks/base/services/core/Android.bp
Based ENTIRELY upon Answer provided by @RickSanchez
, I followed these steps as guided by his answer to bring up a successful build:
[android]prebuilts/misc/common/jsoup/
jsoup
folder, I included a blueprint file Android.bp
and jsoup-1.13.1.jar
downloaded from https://jsoup.org/downloadAndroid.bp
talked above as follows:Android.bp
java_import { name: "jsoup-1.13.1", host_supported: true, installable: false, jars: ["jsoup-1.13.1.jar"], }
Next task was to give ref of above created Local Blueprint file to Android.bp
present in frameworks/base/services/core/Android.bp
To this, I made the following edit: In Android.bp
either add the following if present or modify the following block -
static_libs: [ "jsoup-1.13.1", /*use jsoup lib */ "android.hardware.authsecret-V1.0-java",........ ],
The build is now successful and the sample.java is successfully able to use jsoup library
