I'm trying to build tflite in my android project using cmake. I've managed to work this approach on the linux (debian) version of the same project.When compiling the arm64 version I followed the official docs When I open android studio and press build/run on top right corner, I get this error:
In file included from /home/user/Desktop/official_stuff/tensorflow_src/tensorflow/lite/python/interpreter_wrapper/numpy.cc:17:
In file included from /home/user/Desktop/official_stuff/tensorflow_src/tensorflow/lite/python/interpreter_wrapper/numpy.h:49:

/usr/include/python3.9/pyconfig.h:9:12: fatal error: 'aarch64-linux-gnu/python3.9/pyconfig.h' file not found
When I open the file that throws the error I see the this line indicating that it's searching for it in the system:
#include <aarch64-linux-gnu/python3.9/pyconfig.h>
I ran sudo find / -name "aarch64-linux-gnu" to see whether I have that file or not and indeed I have this file installed:
user#debian:~$ sudo find / -name "aarch64-linux-gnu"
...

I located inside /usr/include/aarch64-linux-gnu and indeed saw /python3.9/pyconfig.h.
The way I did everything is this:
sudo git clone https://github.com/tensorflow/tensorflow.git /home/user/Desktop/official_stuff/tensorflow_src
curl -LO https://storage.googleapis.com/mirror.tensorflow.org/developer.arm.com/media/Files/downloads/gnu-a/8.3-2019.03/binrel/gcc-arm-8.3-2019.03-x86_64-aarch64-linux-gnu.tar.xz

-DCMAKE_VERBOSE_MAKEFILE:BOOL=ON \

../tensorflow/lite/
And then I needed to ran dpkg --add-architecture arm64, apt-get update, sudo apt install libpython3-dev:arm64
I simply clicked build ran after connecting my android device. It compiled for a while and then throw the error.
Here is the cmake snippet I ran that contains my tflite inclusion:
set(TENSORFLOW_SOURCE_DIR "" CACHE PATH
"Directory that contains the TensorFlow project" )
if(NOT TENSORFLOW_SOURCE_DIR)
get_filename_component(TENSORFLOW_SOURCE_DIR

endif()
add_library(tensorflowlite SHARED IMPORTED)
add_subdirectory(

"${CMAKE_CURRENT_BINARY_DIR}/tensorflow-lite" EXCLUDE_FROM_ALL
)
...
target_link_libraries(
my_proj
tensorflow-lite
)
How can I fix this issue?
Note: I got to this point following a series of questions which all resolved:
An undefined error.
Question regarding android build.
More details about how I built everything can be found here. I'm on debian 11.
I want to test the app with android 10 in emulator.So for that I only have "armeabi", "armeabi-v7a","arm64-v8a" in jnilibs. But running app with android 10 device(Emulator), requires x86 abi. So for that first I have downloaded ndk for x86.And the second thing is I want to generate libpjsua2.so for x86 abi.
I am using pjsip library.
I have referred to https://trac.pjsip.org/repos/wiki/Getting-Started/Android. What I have tried is,
1) Downloaded latest pjsip version and extracted in folder.
2) Followed the steps given in pjsip website as below,
$ cd /path/to/your/pjsip/dir
$ export ANDROID_NDK_ROOT=/path_to_android_ndk_dir
$ ./configure-android
$ make dep && make clean && make
$ cd /path/to/your/pjsip/dir
$ make clean
# cleanup pjsua sample app
$ cd pjsip-apps/src/pjsua/android/jni
$ make clean
# also cleanup pjsua2 sample app (SWIG)
$ cd /path/to/your/pjsip/dir
$ cd pjsip-apps/src/swig
$ make clean
$ cd pjsip-apps/src/swig
$ make clean
TARGET_ABI=x86 ./configure-android --use-ndk-cflags
Got error when reached above code,
LDFLAGS = --sysroot= -L/libs/x86/
LIBS = -lgnustl_static -lc -lgcc -ldl
AR = /home/Android/android-ndk-r21b/toolchains/llvm/prebuilt/linux-x86_64/bin/clang++
RANLIB = /home/Android/android-ndk-r21b/toolchains/llvm/prebuilt/linux-x86_64/bin/clang++
TARGET_HOST = llvm-linux-android
TARGET_ABI = x86
checking build system type... x86_64-unknown-linux-gnu
checking host system type... Invalid configuration `llvm-linux-android': machine `llvm' not recognized
aconfigure: error: /bin/sh ./config.sub llvm-linux-android failed
In my pjsip2.7 folder I found a folder named llvm but that is a empty folder. I doesn't know What is that. I am using cent os 7. Why I am getting this error? What do I need to do to overcome this.
Try compile with this builder
replace in ./config.cong you are using 2.10
# PJSIP Version to download
PJSIP_VERSION=2.10
./prepare-build-system
and then
./build

I am trying to build an Android Studio project inside docker using gradle.
Gradle goes through a long process of downloading my dependencies. I would like to cache this step inside docker, so that it is not repeated every time I build.
I am unhappy with the underlying snippet from my Dockerfile (full file below). It requires that I copy my resource directory. Everytime I change a string or a resource, all of my dependencies will be downloaded again! (Because docker cache will be invalidated)
COPY my-android-project/app/src/main/res app/src/main/res
This line will trigger alot of redundant dependency downloads by docker. How can I remove it from my dockerfile? I would appreciate a Dockerfile example with even a trivial "empty activity" Android Studio project...

I am facing a problem while running Android sdkmanager with Java 11 (Not studio, only SDK tools). I don't want to install JDK 8 or something similar. Is there a way to fix this for Android sdkmanager with JDK 11?
I have gone through this answer and it doesn't offer command line fix for java 11. Any other workaround possible?
UPDATE: as explained in another answer, the sdkmanager from the new command line tool supports JDK 11+. The old sdkmanager has not received updates in years, so this workaround should not be necessary. Check #dmertins answer for links and more details.
If anyone is looking for a Linux fix on Java 11. I built this on top of previous answers

After the download finishes (make sure all files were downloaded OK), you have to edit sdkmanager and avdmanager scripts in the tools/bin directory. You can do this manually or automatically.
From Simon Ruggier answer (doesn't work on mac unless you use gnu-sed):
sed -ie 's%^CLASSPATH=.*%\0:$APP_HOME/jaxb_lib/*%' bin/sdkmanager bin/avdmanager
Or manually, scroll down to the CLASSPATH variable, and add the new jars we just downloaded like this:
CLASSPATH=$APP_HOME/jaxb_lib/activation.jar:$APP_HOME/jaxb_lib/jaxb-impl.jar:$APP_HOME/jaxb_lib/jaxb-xjc.jar:$APP_HOME/jaxb_lib/jaxb-core.jar:$APP_HOME/jaxb_lib/jaxb-jxc.jar:$APP_HOME/jaxb_lib/jaxb-api.jar:<etc etc...DO NOT REMOVE THE OTHER JARS!...>
The sdkmanager that comes with the deprecated SDK Tools package doesn't support JDK 8 and is no longer receiving updates since september 2017. More information here and here.
The sdkmanager included in the new Command-Line Tools package supports JDK 11 and it can be downloaded from the Android Studio download page, in the Command line tools only section. There's no need to download any other files or to hack with the sdkmanager script, however you will need to update your PATH setting, e.g. on Linux: $ANDROID_HOME/cmdline-tools/latest/bin instead of $ANDROID_HOME/tools/bin
Although deprecated, the old Tools package is still being installed with Android Studio 4.1.1 by default. This post explains why.
For those of you seeing this issue in Travis CI:
I was seeing this error while attempting to accept the license agreement for build tools 30.0.2, targeting Android 30, with Java 11 for a travis CI build.

# Append jaxb_lib to the CLASSPATH in sdkmanager and avdmanager
sed -ie 's%^CLASSPATH=.*%\0:$APP_HOME/jaxb_lib/*%' bin/sdkmanager bin/avdmanager
The jar directory also doesn't belong under bin, so these instructions place it one level higher.
There is an issues according to previous answers, that you'd better to use more recent jaxb-impl jar such as 2.3.1 to avoid the reflection warning.
https://repo1.maven.org/maven2/com/sun/xml/bind/jaxb-impl/2.3.1/jaxb-impl-2.3.1.jar
Also if we put all jar files into ${APP_HOME}/lib and then append ${APP_HOME}/lib/* to CLASSPATH, the java will pick up all jar files.
If you are on Apple Silicon or don't have wget installed:
cd Android/sdk/tools # or Android/tools
mkdir jaxb_lib
curl https://repo1.maven.org/maven2/javax/activation/activation/1.1.1/activation-1.1.1.jar -o jaxb_lib/activation.jar

# Add To CLASSPATH
sed -ie 's%^CLASSPATH=.*%\0:$APP_HOME/jaxb_lib/*%' bin/sdkmanager bin/avdmanager
# Add this manually on newline after CLASSPATH
CLASSPATH=$APP_HOME/jaxb_lib/activation.jar:$APP_HOME/jaxb_lib/jaxb-impl.jar:$APP_HOME/jaxb_lib/jaxb-xjc.jar:$APP_HOME/jaxb_lib/jaxb-core.jar:$APP_HOME/jaxb_lib/jaxb-jxc.jar:$APP_HOME/jaxb_lib/jaxb-api.jar:$APP_HOME/jaxb_lib/istack-commons-runtime.jar:$CLASSPATH
After trying Wang Qian's answer, I got Exception in thread "main" java.lang.NoSuchFieldError: REFLECTION. This might because the versions of jaxb-impl and jaxb-core are not matching. Make sure you download the same version of these two libraries, such as 2.3.0.1.
After that, I got another exception: Exception in thread "main" java.lang.NoClassDefFoundError: com/sun/istack/FinalArrayList. I found out this is because we are missing another library: istack-commons-runtime. Download it and put it into the classpath as well.
So the full list of library dependencies that need to add to classpath specifically should be:
jaxb-api
jaxb-core
jaxb-impl
jaxb-jxc
jaxb-xjc
activation
istack-commons-runtime
After this, you should be able to run sdkmanager but with a warning of illegal reflective access. You can ignore it without any problems. If you are interested in it, have a quick search. You'll find lots of questions on Stack Overflow regarding this warning.

Using Java 12, these are the steps I followed to bypass this warning. Thanks to Wang Qian.
Navigate to the path where the android sdk is installed such as the following.
%LOCALAPPDATA%\Android\Sdk\tools\bin
Edit sdkmanager.bat with a text editor such as notepad.
Find the following lines at approximately line 70.
#rem Execute sdkmanager
"%JAVA_EXE%" %DEFAULT_JVM_OPTS% %JAVA_OPTS% %SDKMANAGER_OPTS% -classpath "%CLASSPATH%" com.android.sdklib.tool.sdkmanager.SdkManagerCli %CMD_LINE_ARGS%
Just above those lines, paste the following code.
set CLASSPATH=%CLASSPATH%;%APP_HOME%\mylib\jaxb-api.jar
set CLASSPATH=%CLASSPATH%;%APP_HOME%\mylib\jaxb-core.jar
set CLASSPATH=%CLASSPATH%;%APP_HOME%\mylib\jaxb-impl.jar
set CLASSPATH=%CLASSPATH%;%APP_HOME%\mylib\jaxb-jxc.jar
set CLASSPATH=%CLASSPATH%;%APP_HOME%\mylib\jaxb-xjc.jar
set CLASSPATH=%CLASSPATH%;%APP_HOME%\mylib\activation.jar
Create a new folder called mylib in the tools folder of your android sdk installation.
%LOCALAPPDATA%\Android\Sdk\tools\mylib
Download the latest version of the following 6 jar files and place them in the mylib folder.
https://repo1.maven.org/maven2/javax/activation/activation/
https://repo1.maven.org/maven2/javax/xml/bind/jaxb-api/
https://mvnrepository.com/artifact/org.glassfish.jaxb/jaxb-core
https://mvnrepository.com/artifact/com.sun.xml.bind/jaxb-impl
https://mvnrepository.com/artifact/com.sun.xml.bind/jaxb-xjc
https://repo1.maven.org/maven2/org/glassfish/jaxb/jaxb-jxc/
Remove the versioning in the filenames to match the filenames set in the sdkmanager.bat file. You should now have the following files.
%LOCALAPPDATA%\Android\Sdk\tools\mylib\activation.jar
%LOCALAPPDATA%\Android\Sdk\tools\mylib\jaxb-api.jar
%LOCALAPPDATA%\Android\Sdk\tools\mylib\jaxb-core.jar
%LOCALAPPDATA%\Android\Sdk\tools\mylib\jaxb-impl.jar
%LOCALAPPDATA%\Android\Sdk\tools\mylib\jaxb-jxc.jar
%LOCALAPPDATA%\Android\Sdk\tools\mylib\jaxb-xjc.jar
All set! Now run your sdkmanager --update command
%LOCALAPPDATA%\Android\sdk\tools\bin\sdkmanager --update
If you're on macOS using the android-sdk formula from Homebrew, it's discontinued and only supports Java 8. Quoting its formula page:
android-sdk requires Java 8. You can install it with:
brew install --cask homebrew/cask-versions/temurin8
android-sdk has been officially discontinued upstream. It may stop
working correctly (or at all) in recent versions of macOS.
For Java 11 and newer, you can install the android-commandlinetools formula.
brew install android-commandlinetools
Don't forget to set the ANDROID_HOME variable pointing to your "new" Android SDK directory:
export ANDROID_HOME=/usr/local/share/android-commandlinetools
