+## Compile libpcap for multiple targets and API versions
+
+You can use the `build_libpcap_all.sh` script to run the scripts mentioned above for multiple targets and Android API versions.
+This can be useful if you need to buid libpcap for multiple targets / API versions.
+
+1. Run the script `build_libpcap_all.sh` and set `NDK` to the location of the android sdk directory.
+
+2. You can also specify the following parameters:
+
+ - `OUTPUT_DIR` for the output directory. The default is `libpcap_all_targets`.
+ - `TARGETS` one or more targets from this list: `arm arm64 x86 x86_64`. The default is all of them.
+ - `API_MIN` min API version. The default is 21.
+ - `API_MAX` max API version. The default is 30.
+
+3. Examples:
+ ```
+ $ NDK=/home/ubuntu/workspace/android-ndk-rxxx/ ./build_libpcap_all.sh
+ $ NDK=/home/ubuntu/workspace/android-ndk-rxxx/ OUTPUT_DIR=my_dir ./build_libpcap_all.sh
+ $ NDK=/home/ubuntu/workspace/android-ndk-rxxx/ TARGETS="x86 x86_64" ./build_libpcap_all.sh
+ $ NDK=/home/ubuntu/workspace/android-ndk-rxxx/ API_MIN=21 API_MAX=30 /build_libpcap_all.sh
+ ```
