+# pjsua2maui - pjsip on .net maui 
+
+## STEPS FOR BUILDING:
+
+### Android
+
+- SETUP:
+    - Visual Studio Code & .NET MAUI - [Install steps](https://learn.microsoft.com/en-us/dotnet/maui/get-started/installation?view=net-maui-11.0&tabs=visual-studio-code)
+    - Java 17 
+    - Android NDK r21d or later
+    - pjsip v2.14.1 or later
+
+-  Run the following commands:
+
+```bash 
+    export ANDROID_SDK_ROOT=/somewhere/there/is/installed/the/sdk/
+    sdkmanager --install "ndk;28.0.12674087" --channel=3 --sdk_root=$ANDROID_SDK_ROOT
+    sdkmanager --install "cmake;3.31.0" --sdk_root=$ANDROID_SDK_ROOT
+    sdkmanager --install "build-tools;35.0.0" "platform-tools" "platforms;android-35" --sdk_root=$ANDROID_SDK_ROOT
+    echo yes | sdkmanager --licenses --sdk_root=$ANDROID_SDK_ROOT
+```
+note:
+If you are sharing the Android SDK location with Android Studio, the recommended way to install/update the SDK and accept licenses is by using Android Studio.
+
+- Create the following variable: 
+
+```bash
+
+export ANDROID_NDK_ROOT=/path/to/ndk/root/installation
+
+```
+
+- Then build pjsip
+
+For device: 
+```bash
+    ./configure-android
+```
+
+For simulator:
+```bash
+
+TARGET_ABI=x86_64  ./configure-android
+make dep && make clean && make
+
+```
+
+
+after run make dep and make, run the make on ``` pjsip-apps/src/swig/csharp ``` folder
+
+```bash
+
+make 
+
+```
+
+then start the android emulator, go to ``` pjsip-apps/src/swig/csharp/pjsua2maui/pjsua2maui ``` and run:
+
+```bash
+
+dotnet workload restore
+dotnet restore
+dotnet build -t:Run -c Debug -f net9.0-android  
+
+```
+or, for run in device:
+
+Open Android Studio and connect an Android device, such as by using "Pair Devices Using Wifi"
+(Optional) Start Logcat in VS Code, for obtaining Android log.
+Install Logcat: View-Extensions. Install Logcat extension.
+Start Logcat: View-Command Pallette.
+
+### iOS
+
+- SETUP:
+    - Visual Studio Code & .NET MAUI - [Install steps](https://learn.microsoft.com/en-us/dotnet/maui/get-started/installation?view=net-maui-11.0&tabs=visual-studio-code)
+    - Xcode 16.1 or later
+    - pjsip v2.14.1 or later
+
+- PREPARING:
+
+- Building pj stack:
+
+Create the following ``` config_site.h ```  :
+
+```c 
+
+#define PJ_CONFIG_IPHONE 1
+
+#include <pj/config_site_sample.h>
+
+```
+Create the following variable:
+
+```bash
+
+export DEVPATH="`xcrun -sdk iphonesimulator --show-sdk-platform-path`/Developer"
+
+```
+Run configure with the following flags to build the lib to run on simulator:
+
+```bash
+
+MIN_IOS="-miphoneos-version-min=12.2" ARCH="-arch x86_64" CFLAGS="-O2 -m32 -mios-simulator-version-min=12.2 -fembed-bitcode" LDFLAGS="-O2 -m32 -mios-simulator-version-min=12.2 -fembed-bitcode" ./configure-iphone
+
+```
+For run on device: 
+
+```bash
+./configure-iphone
+```
+
+after run make dep and make, run the make on ``` pjsip-apps/src/swig/csharp ``` folder
+
+```bash
+
+make 
+
+```
+
+then go to ``` pjsip-apps/src/swig/csharp/pjsua2maui/pjsua2maui ``` and run:
+
+For simulator:
+
+```bash
+dotnet workload restore
+dotnet restore
+dotnet build -t:Run -c Debug -f net9.0-ios -p:_DeviceName=:v2:udid=UDID_OF_YOUR_EMULATOR
+```
+
+For device:
+
+```bash
+dotnet workload restore
+dotnet restore
+dotnet build -t:Run -c Debug -f net9.0-ios -p:_DeviceName=:v2:udid=UDID_OF_YOUR_DEVICE
+```
+
+For the codesign, here are the steps:
+
+```bash
+dotnet publish -c Debug -f net9.0-ios -p:RuntimeIdentifier=ios-arm64
+```
+Open the resulting .ipa file in Xcode: ``` pjsip-apps/src/swig/csharp/pjsua2maui/pjsua2maui/bin/Debug/net9.0-ios/ios-arm64/publish/pjsua2maui.ipa ```
+
+Drag it to your connected device under "Devices and Simulators."
+Xcode will handle the signing and deployment.
