 Building on Android
 ===================
-There are two versions: with QT and without QT.
+### Note: *Build works ONLY on Linux systems. Current documentation shows how to build application on Ubuntu 18.04*
 Pre-requisites
 --------------
-You need to install Android SDK and NDK. For QT version, you also need QT with android support.
+You need to install `rename` (required for building libraries), `OpenJDK` 11+, `gradle` 5.1+ and `Android SDK`.
- [SDK](https://developer.android.com/studio/index.html) (choose command line tools only, and make sure you installed "Android SDK Build-Tools")
+```
- [NDK](https://developer.android.com/ndk/downloads/index.html)
+sudo apt-get install g++ rename openjdk-11-jdk gradle
- [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 (prefer Oracle Java 8), Ant and [latest Gradle](https://gradle.org/releases/) (min version 3.4).
 QT-Creator (for QT only)
 ------------------------
-Open QT-creator that should be installed with QT.
+- Android [SDK](https://developer.android.com/studio#downloads) (choose command line tools only)
-Go to Settings/Android and specify correct paths to SDK and NDK.
+- If your system provides gradle with version < 5.1, download it from [Gradle](https://gradle.org/install/) homepage
 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.
+Prepare Android SDK and install required packages
-	git clone https://github.com/PurpleI2P/Boost-for-Android-Prebuilt.git -b boost-1_72_0
+```bash
-	git clone https://github.com/PurpleI2P/OpenSSL-for-Android-Prebuilt.git
+mkdir /tmp/android-sdk
-	git clone https://github.com/PurpleI2P/MiniUPnP-for-Android-Prebuilt.git
+cd /tmp/android-sdk
-	git clone https://github.com/PurpleI2P/android-ifaddrs.git
+wget <latest SDK link>
 unzip commandlinetools-linux-*_latest.zip
 # install required tools
 ./cmdline-tools/bin/sdkmanager --sdk_root=/opt/android-sdk "build-tools;31.0.0" "cmake;3.18.1" "ndk;21.4.7075529"
 ```
-Prepare Android SDK and install required packages
+Clone repository with submodules
 ```bash
 git clone --recurse-submodules https://github.com/PurpleI2P/i2pd-android.git
 ```
 Compile required libraries
-	mkdir android-sdk
+```bash
-	cd android-sdk
+export ANDROID_SDK_ROOT=/opt/android-sdk
-	wget -t0 <link to latest SDK from Android site>
+export ANDROID_NDK_HOME=$ANDROID_SDK_ROOT/ndk/21.4.7075529
 	unzip commandlinetools-XXXXXX-XXXXXX.zip -d cmdline-tools
 	./cmdline-tools/tools/bin/sdkmanager "build-tools;25.0.3" "platforms;android-14" "platforms;android-25" "platform-tools"
-Building the app with QT
+pushd app/jni
------------------------
+./build_boost.sh
 ./build_openssl.sh
 ./build_miniupnpc.sh
 popd
 ```
- Open `qt/i2pd_qt/i2pd_qt.pro` in the QT-creator
+Building Android application
- 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
+### Build application
 ---------------------------
- Change line `I2PD_LIBS_PATH` in `android/jni/Application.mk` to an actual path where you put the dependencies to
+- Create `local.properties` file with path to SDK and NDK
- Create or edit file 'local.properties'. Place 'sdk.dir=`<path to SDK>`' and 'ndk.dir=`<path to NDK>`'
+  ```
- Run `gradle clean cleanBuildCache assembleDebug` from `android` folder
+  sdk.dir=/opt/android-sdk
- You will find an .apk file in `android/build/outputs/apk` folder
+  ndk.dir=/opt/android-sdk/ndk/21.4.7075529
  ```
 - Run `gradle clean assembleDebug`
 - You will find an .apk file in `app/build/outputs/apk` folder
-Creating release .apk
+### 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-known 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).
+For example, i2pd release are signed with this [certificate](https://raw.githubusercontent.com/PurpleI2P/i2pd/9000b3df4edcbe7f2c8afd0e1e30609746311ace/contrib/certificates/router/orignal_at_mail.i2p.crt).
