Android app crashes with UnsatifiedLinkError - which NDK/SDK to use?
Solved
Mobile and Embedded
-
I have inherited the code for an app, and am currently trying to build a working APK.
I thought the build was working (generated a APK) but when running it on a VirtuallBox Android x86 emulator it crashed, indicating the issue was the build target was ARM, not x86.
I looked closely at the scripts and there were a number of
ANDROID_NDKvariables in the shell script. I tried experimenting but I am unable to get the app to run . I tried the app on a Android tablet as well and it crashed there too.#!/bin/bash export ANDROID_NDK_ROOT=/opt/android-ndk/android-ndk-r19c export ANDROID_SDK_ROOT=/shared/DevTools/Android/SDK-r25.2.5 export ANDROID_HOME=/usr/lib/android-sdk export ANDROID_NDK_HOST=linux-x86_64 export ANDROID_NDK_PLATFORM=android-21 export ANDROID_TARGET_PLATFORM=android-21 export JAVA_HOME=/usr/lib/jvm/java-8-openjdk-amd64 export ANDROID_NDK_TOOLCHAIN_VERSION=4.9 export ANDROID_NDK_TOOLCHAIN_PREFIX=x86 export ANDROID_NDK_TOOLS_PREFIX=x86 export ANDROID_TARGET_ARCH=x86 QT_AND_PATH=/opt/Qt5.12.3/5.12.3/android_x86/bin PACKAGE_NAME=MyApp BUILD_OUT=/tmpbuild/android-$PACKAGE_NAME OUTPUT_PATH=$BUILD_OUT/build/outputs/apk/release rm -rf $BUILD_OUT $QT_AND_PATH/qmake $PACKAGE_NAME.pro -r -spec android-clang "CONFIG+=release" DEFINES+= LIB_PATH=$DEPENDENCIES_PATH # make make -j $THREADS > /dev/null make install INSTALL_ROOT=$BUILD_OUT > /dev/null VB="--verbose" CERTFILE=/certs/MyAppe.keystore.2021 PWD_KEYSTORE=MyPass2021 PWD_KEY=MySKPass2021 $QT_AND_PATH/androiddeployqt $VB --output $BUILD_OUT --input android-libMyApp.so-deployment-settings.json --deployment bundled --android-platform $ANDROID_TARGET_PLATFORM --gradle --sign $CERTFILE softoffice --storepass $PWD_KEYSTORE --keypass $PWD_KEYWhen I install and run the app I get the following errors in
