{#samples_kotlin_android_occt} +================== + +This sample demonstrates simple way of using OCCT libraries in Android application written using Kotlin. + +The connection between Kotlin and OCCT (C++) level is provided by proxy library, libTKJniSample.so, written in C++ with exported JNI methods of Kotlin class OcctJniRenderer. +The proxy library contains single C++ class OcctJni_Viewer encapsulating OCCT viewer and providing functionality to manipulate this viewer +and to import OCCT shapes from several supported formats of CAD files (IGES, STEP, BREP). + +This sample demonstrates indirect method of wrapping C++ to Kotlin using manually created proxy library. + +Install Android Studio 4.0+ and building tools (check Tools -> SDK Manager): +- Android SDK (API level 21 or higher). +- Android SDK build tools. +- Android NDK r16 or higher (coming with CMake toolchain). + Using NDK r18 or newer will require changing ANDROID_STL in project settings. +- CMake 3.10+. + +Specify this folder location in Android Studio for opening project. +You might need re-entering Android SDK explicitly in File -> Project Structure -> SDK Location settings (SDK, NDK, JDK locations). + +This sample expects OCCT to be already build - please refer to appropriate CMake building instructions in OCCT documentation. +The following variables should be added into file gradle.properties (see gradle.properties.template as template): +- `OCCT_ROOT` - path to OCCT installation folder. +- `FREETYPE_ROOT` - path to FreeType installation folder. + +FreeImage is optional and does not required for this sample, however you should include all extra libraries used for OCCT building +and load the explicitly from Java code within OcctJniActivity::loadNatives() method, including toolkits from OCCT itself in proper order: +~~~~ + if (!loadLibVerbose ("TKernel", aLoaded, aFailed) + || !loadLibVerbose ("TKMath", aLoaded, aFailed) + || !loadLibVerbose ("TKG2d", aLoaded, aFailed) +~~~~ +Note that C++ STL library is not part of Android system, and application must package this library as well as extra component ("gnustl_shared" by default - see also `ANDROID_STL`). + +After successful build via Build -> Rebuild Project, the application can be packaged to Android: +- Deploy and run application on connected device or emulator directly from Android Studio using adb interface by menu items "Run" and "Debug". This would sign package with debug certificate. +- Prepare signed end-user package using wizard Build -> Generate signed APK. diff --git a/samples/kotlin/jniviewer/app/build.gradle b/samples/kotlin/jniviewer/app/build.gradle new file mode 100644 index 0000000000..277b8b4671 --- /dev/null +++ b/samples/kotlin/jniviewer/app/build.gradle @@ -0,0 +1,53 @@ +apply plugin: 'com.android.application' +apply plugin: 'kotlin-android' + +android { + compileSdkVersion 21 + buildToolsVersion "30.0.0" + + defaultConfig { + applicationId "com.opencascade.jnisample" + minSdkVersion 21 + targetSdkVersion 26 + + ndk { + abiFilters "arm64-v8a" + } + + externalNativeBuild { + cmake { + arguments "-DOCCT_ROOT=" + OCCT_ROOT, + "-DFREETYPE_ROOT=" + FREETYPE_ROOT, + "-DANDROID_STL=gnustl_shared" + } + } + } + + buildTypes { + release { + minifyEnabled false + proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt' + } + } + + sourceSets { + main { + manifest.srcFile 'src/main/AndroidManifest.xml' + assets.srcDirs = [OCCT_ROOT + "/src"] + } + } + + externalNativeBuild { + cmake { + path "src/main/jni/CMakeLists.txt" + } + } +} + +dependencies { + implementation fileTree(dir: 'java/com/opencascade/jnisample', include: ['*.jar']) + implementation "org.jetbrains.kotlin:kotlin-stdlib-jdk7:$kotlin_version" +} +repositories { + mavenCentral() +} diff --git a/samples/kotlin/jniviewer/app/src/main/AndroidManifest.xml b/samples/kotlin/jniviewer/app/src/main/AndroidManifest.xml new file mode 100644 index 0000000000..c25a6d6389 --- /dev/null +++ b/samples/kotlin/jniviewer/app/src/main/AndroidManifest.xml @@ -0,0 +1,43 @@ + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + diff --git a/samples/kotlin/jniviewer/app/src/main/java/com/opencascade/jnisample/OcctJniActivity.kt b/samples/kotlin/jniviewer/app/src/main/java/com/opencascade/jnisample/OcctJniActivity.kt new file mode 100644 index 0000000000..714c187d8c --- /dev/null +++ b/samples/kotlin/jniviewer/app/src/main/java/com/opencascade/jnisample/OcctJniActivity.kt @@ -0,0 +1,692 @@ +// Copyright (c) 2014-2021 OPEN CASCADE SAS +// +// This file is part of the examples of the Open CASCADE Technology software library. +// +// Permission is hereby granted, free of charge, to any person obtaining a copy +// of this software and associated documentation files (the "Software"), to deal +// in the Software without restriction, including without limitation the rights +// to use, copy, modify, merge, publish, distribute, sublicense, and/or sell +// copies of the Software, and to permit persons to whom the Software is +// furnished to do so, subject to the following conditions: +// +// The above copyright notice and this permission notice shall be included in all +// copies or substantial portions of the Software. +// +// THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR +// IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, +// FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
