How to use 3rd party jar in system app - Android Q&A, Help & Troubleshooting

I want to use a 3rd party jar in the system app - Settings.
I have tried two methods, but both failed.
The Android version is 4.2.2 JB.
The first method is that I put the jar file into /packages/apps/Settings/ and modify the Android.mk.
Code:
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_JAVA_LIBRARIES := bouncycastle telephony-common
LOCAL_STATIC_JAVA_LIBRARIES := guava android-support-v4 jsr305 nxpnfclib
LOCAL_MODULE_TAGS := optional
LOCAL_SRC_FILES := $(call all-java-files-under, src)
LOCAL_PACKAGE_NAME := Settings
LOCAL_CERTIFICATE := platform
LOCAL_PROGUARD_FLAG_FILES := proguard.flags
include $(BUILD_PACKAGE)
include $(CLEAR_VARS)
LOCAL_PREBUILT_STATIC_JAVA_LIBRARIES := nxpnfclib.jar
include $(BUILD_MULTI_PREBUILT)
# Use the folloing include to make our test apk.
include $(call all-makefiles-under,$(LOCAL_PATH))
Some proguard warnings show up:
Code:
Warning: class [com/nxp/nfclib/ntag/╦К.class] unexpectedly contains class [com.nxp.nfclib.ntag.ˊ]
Warning: there were 30 classes in incorrectly named files. You should make sure all file names correspond
to their class names. The directory hierarchies must correspond to the package hierarchies. If you don't mind
the mentioned classes not being written out, you could try your luck using the '-ignorewarnings' option.
Error: Please correct the above warnings first. make: *** [out/target/common/obj/APPS/Settings_intermed
iates/proguard.classes.jar] Error 1
Then I add some proguard flags to prevent this warnings. I can compile Android now. However, when I boot the system, some errors show up:
Code:
W/dalvikvm( 732): Unable to resolve superclass of Lcom/nxp/nfclib/ntag/NTag213215216; (1855)
W/dalvikvm( 732): Link of class 'Lcom/nxp/nfclib/ntag/NTag213215216;' failed
W/dalvikvm( 732): Unable to resolve superclass of Lcom/nxp/nfclib/ntag/NTag213F216F; (1844)
W/dalvikvm( 732): Link of class 'Lcom/nxp/nfclib/ntag/NTag213F216F;' failed
E/dalvikvm( 732): Could not find class 'com.nxp.nfclib.ntag.NTag213F216F', referenced from method com.nxp.nfclib.NxpNfcLib.ˊ
Another mothod: I put the jar file to /prebuilts/misc/common/nxp and write an Android.mk:
Code:
LOCAL_PATH:= $(call my-dir)
include $(CLEAR_VARS)
LOCAL_PREBUILT_JAVA_LIBRARIES := \
nxpnfclib$(COMMON_JAVA_PACKAGE_SUFFIX)
LOCAL_MODULE_TAGS := optional
include $(BUILD_HOST_PREBUILT)
Then modify /packages/apps/Settings/Android.mk:
Code:
LOCAL_STATIC_JAVA_LIBRARIES := guava android-support-v4 jsr305 nxpnfclib
However, when I compile the whole AOSP, the same proguard warnings show up:
Code:
Warning: class [com/nxp/nfclib/ntag/╦К.class] unexpectedly contains class [com.nxp.nfclib.ntag.ˊ]
Warning: there were 30 classes in incorrectly named files. You should make sure all file names correspond
to their class names. The directory hierarchies must correspond to the package hierarchies. If you don't mind
the mentioned classes not being written out, you could try your luck using the '-ignorewarnings' option.
Error: Please correct the above warnings first. make: *** [out/target/common/obj/APPS/Settings_interm
ediates/proguard.classes.jar] Error 1
Is there some other way to add the jar?
The jar runs well if I use Android Studio to build an app.
Can I put the jar in the system instead of merge it into the system?

[Q] Building a specific apk from CM7 sources

i was trying to build framework-res.apk
i went into android_frameworks_base/core/res from terminal
theres an Android.mk file there:
Code:
LOCAL_PATH := $(call my-dir)
include $(CLEAR_VARS)
LOCAL_NO_STANDARD_LIBRARIES := true
LOCAL_PACKAGE_NAME := framework-res
LOCAL_CERTIFICATE := platform
# Tell aapt to create "extending (non-application)" resource IDs,
# since these resources will be used by many apps.
LOCAL_AAPT_FLAGS := -x
LOCAL_MODULE_TAGS := optional
# Install this alongside the libraries.
LOCAL_MODULE_PATH := $(TARGET_OUT_JAVA_LIBRARIES)
# Create package-export.apk, which other packages can use to get
# PRODUCT-agnostic resource data like IDs and type definitions.
LOCAL_EXPORT_PACKAGE_RESOURCES := true
include $(BUILD_PACKAGE)
# define a global intermediate target that other module may depend on.
.PHONY: framework-res-package-target
framework-res-package-target: $(LOCAL_BUILT_MODULE)
and then i did
make framework-res
make: *** No rule to make target `framework-res'. Stop.
can u help me with the process? im just a beginner.

Compiling android - trying to add XML files to /system/etc/permissions

I'm compiling android from source. I've set up the environment, and tested the builds. Everything works fine.
My current objective is to add 10 custom xml files to /system/etc/permissions. I've tried modifying the Android.mk file in frameworks/base/data/etc to include the files, but the additions aren't appearing in the compiled system. What's strange is that the default files that were in the same folder and already in the makefile appear, so the makefile seems to be read and parsed at compile.
This is the code I'm using:
Code:
LOCAL_PATH := $(my-dir)
include $(CLEAR_VARS)
LOCAL_MODULE := [B]default_file_already_present.xml[/B]
LOCAL_MODULE_CLASS := ETC
LOCAL_MODULE_PATH := $(TARGET_OUT)/permissions
LOCAL_SRC_FILES := $(LOCAL_MODULE)
include $(BUILD_PREBUILT)
include $(CLEAR_VARS)
LOCAL_MODULE := [B]my_custom_file.xml[/B]
LOCAL_MODULE_CLASS := ETC
LOCAL_MODULE_PATH := $(TARGET_OUT)/permissions
LOCAL_SRC_FILES := $(LOCAL_MODULE)
include $(BUILD_PREBUILT)
For some reason, my_custom_file is not added, while the default_file_already_present is. Any ideas?
I've searched around, but can't find any decent documentation. I feel like I’m very close, so any help is much appreciated!
tl;dr - Adding files to system partition with makefile partially fails.
Solution!
For those who also run in to this problem:
As per Jean-Baptiste Quéru's post on a google group;
The Android makefiles are essentially split into 2 primary categories,
parsed in this order.
-the product definitions, which specify what modules need to be
installed for each product.
-the module definition, which specify how to build each module.
The build system protects itself against situation where you modify
the product definition from a module definition. PRODUCT_COPY_FILES is
part of the product definition, and can't be modify from a module
definition.

What this means is that in order to copy files as is to the system image, we need to use product definitions.
What I did was first run ./build/envsetup.sh, in order to get access to commands like mgrep, etc.
I noticed that in frameworks/base/data/keyboards there was a keyboards.mk file, which got included correctly.
I made a copy and modifies it to suit my needs:
Code:
# Copyright (C) 2010 The Android Open Source Project
#
blah blah blah...
#
# This is the list of custom permissions to be injected in /system/etc/permissions
permissionsfiles := \
android.hardware.camera.front.xml \
android.hardware.usb.accessory.xml \
android.hardware.usb.host.xml \
android.hardware.wifi.direct.xml \
android.hardware.wifi.xml \
android.software.sip.voip.xml \
com.google.android.maps.xml \
com.google.android.media.effects.xml \
com.google.widevine.software.drm.xml \
handheld_core_hardware.xml \
platform_plus.xml \
features.xml
PRODUCT_COPY_FILES := $(foreach file,$(permissionsfiles),\
frameworks/base/data/etc/$(file):system/etc/permissions/$(file))
I ran "mgrep keyboards" and noted which makefiles included the keyboards.mk file, then I opened each file and duplicated that line, modifying it to instead include my custom_permissions.mk located in frameworks/base/data/etc/.
I compiled and the files were all there.
Hope this helps.

[Q] How do I properly use a prebuilt kernel with AOSP?

I'm trying to build AOSP for Moto X 2013 (ghost). I've successfully built the kernel separately already (and flashed it to my device to make sure it works) but I can't seem to find a way to tell AOSP to use it. I get the following error when running make -j16 otapackage:
No private recovery resources for TARGET_DEVICE ghost
make: *** No rule to make target `out/target/product/ghost/kernel', needed by `out/target/product/ghost/boot.img'. Stop.
I've already tried to add this line to device.mk:
LOCAL_KERNEL := device/motorola/ghost-kernel/zImage
But it did nothing.
Any ideas?
I think, you should use TARGET_PREBUILT_KERNEL variable
https://stackoverflow.com/questions/9008761/replace-the-prebuilt-kernel-in-the-android-platform-source
http://wiki.cyanogenmod.org/w/Doc:_integrated_kernel_building
Fixed this build step by adding these lines to the device makefile:
Code:
TARGET_PREBUILT_KERNEL := device/motorola/ghost-kernel/zImage
PRODUCT_COPY_FILES += \
$(TARGET_PREBUILT_KERNEL):kernel
Effectively, this copies the kernel file to the output directory to be processed by subsequent steps.

Build Error CM12.1, missing reference to a JAR

Hi,
I currently try building this one myself:
http://forum.xda-developers.com/android/development/rom-cyanogenmod-12-0-samsung-express-gt-t2949359
it's CM 12.1 for the Samsung Galaxy Express GT-I8730
After hours of building it breaks with a missing library.
Code:
frameworks/testing/runner/src/main/java/android/support/test/internal/runner/ClassPathScanner.java:19: error: package android.support.annotation does not exist
import android.support.annotation.VisibleForTesting;
build/core/java.mk:346: recipe for target '~/src/cm-12.1-main/out/target/common/obj/JAVA_LIBRARIES/android-support-test-src_intermediates/classes-full-debug.jar' failed
make: *** [~/src/cm-12.1-main/out/target/common/obj/JAVA_LIBRARIES/android-support-test-src_intermediates/classes-full-debug.jar] Error 41
package android.support.annotation is missing. It's available here
Code:
./frameworks/support/annotations/src/android/support/annotation
./prebuilts/sdk/current/support/annotations/android-support-annotations.jar
But it's not included in build.
This is the code in question, in build/core/java.mk:346
Code:
# Compile the java files to a .jar file.
# This intentionally depends on java_sources, not all_java_sources.
# Deps for generated source files must be handled separately,
# via deps on the target that generates the sources.
$(full_classes_compiled_jar): PRIVATE_JAVACFLAGS := $(LOCAL_JAVACFLAGS)
$(full_classes_compiled_jar): PRIVATE_JAR_EXCLUDE_FILES := $(LOCAL_JAR_EXCLUDE_FILES)
$(full_classes_compiled_jar): PRIVATE_JAR_PACKAGES := $(LOCAL_JAR_PACKAGES)
$(full_classes_compiled_jar): PRIVATE_JAR_EXCLUDE_PACKAGES := $(LOCAL_JAR_EXCLUDE_PACKAGES)
$(full_classes_compiled_jar): PRIVATE_RMTYPEDEFS := $(LOCAL_RMTYPEDEFS)
$(full_classes_compiled_jar): PRIVATE_DONT_DELETE_JAR_META_INF := $(LOCAL_DONT_DELETE_JAR_META_INF)
$(full_classes_compiled_jar): $(java_sources) $(java_resource_sources) $(full_java_lib_deps) \
$(jar_manifest_file) $(layers_file) $(RenderScript_file_stamp) \
$(proto_java_sources_file_stamp) $(LOCAL_ADDITIONAL_DEPENDENCIES)
$(transform-java-to-classes.jar)
How do I find out the content of the variables? How do I modify it?
Since I am building from a branch, it probably is a temporary problem. I issued a repo sync, but it dit not help (yet).
any idea?
thanks
JPT
