+## Android

+Requires android studio to be installed in the system. With it you can build the apk from command line:
+
+```
+make apk
+```
+
+The built apk will be in `android/app/build/outputs/apk/release/app-release-unsigned.apk`.
+
+Or open android studio to test and build the app:
+
+```
+make build
+npx cap copy
+npx cap open android
+```
+
+### sign the apk
+
+To sign the apk you need to have a key generated with:
+
+```
+keytool -genkey -v -keystore release.keystore -alias release -keyalg RSA -keysize 2048 -validity 10000
+```
+
+And then sign it:
+
+```
+apksigner sign --ks ~/release.keystore --out app.apk app-release-unsigned.apk
+```
