Building on Android =================== There are two versions: with QT and without QT. Pre-requisites -------------- You need to install Android SDK, NDK and QT with android support. - [SDK](https://developer.android.com/studio/index.html) (choose command line tools only) - [NDK](https://developer.android.com/ndk/downloads/index.html) - [QT](https://www.qt.io/download-open-source/)(for QT only). Choose one for your platform for android. For example QT 5.6 under Linux would be [this file](http://download.qt.io/official_releases/qt/5.6/5.6.1-1/qt-opensource-linux-x64-android-5.6.1-1.run) You also need Java JDK and Ant. QT-Creator (for QT only) ------------------------ Open QT-creator that should be installed with QT. Go to Settings/Android and specify correct paths to SDK and NDK. If everything is correct you will see two set available: Android for armeabi-v7a (gcc, qt) and Android for x86 (gcc, qt). Dependencies -------------- Take following pre-compiled binaries from PurpleI2P's repositories. git clone https://github.com/PurpleI2P/Boost-for-Android-Prebuilt.git git clone https://github.com/PurpleI2P/OpenSSL-for-Android-Prebuilt.git git clone https://github.com/PurpleI2P/MiniUPnP-for-Android-Prebuilt.git git clone https://github.com/PurpleI2P/android-ifaddrs.git Building the app with QT ------------------------ - Open `qt/i2pd_qt/i2pd_qt.pro` in the QT-creator - Change line `MAIN_PATH = /path/to/libraries` to an actual path where you put the dependencies to - Select appropriate project (usually armeabi-v7a) and build - You will find an .apk file in `android-build/bin` folder Building the app without QT --------------------------- - Change line `I2PD_LIBS_PATH` in `android/jni/Application.mk` to an actual path where you put the dependencies to - Run `ndk-build -j4` from android folder - Create or edit file 'local.properties'. Place 'sdk.dir=' and 'ndk.dir=' - Run `ant clean debug` Creating release .apk ---------------------- In order to create release .apk you must obtain a Java keystore file(.jks). Either you have in already, or you can generate it yourself using keytool, or from one of you existing well-know certificates. For example, i2pd release are signed with this [certificate](https://github.com/PurpleI2P/i2pd/blob/openssl/contrib/certificates/router/orignal_at_mail.i2p.crt). Create file 'ant.properties': key.store='path to keystore file' key.alias='alias name' key.store.password='keystore password' key.alias.password='alias password' Run `ant clean release`
