 # Tools for Android development.

-# HINT: Migration to qemu not yet tested.
+# HINT: Since JDK-8 is no longer available, we have to add clutter to
+#       apksigner command. Eg:
+#       apksigner -J-add-opens=jdk.compiler/com.sun.tools.javac.code=ALL-UNNAMED \
+#                 -J-add-opens=java.base/sun.security.x509=ALL-UNNAMED \
