# This test asserts that the android_app under test does not package ndk libs
#
# Setup
# android_app: SimpleJni
# jni_libs: libsimplejni
# transitive_dep_of_jni_lib: liblog (an NDK library)
#
# Expectation
# SimpleJni.apk contains libsimplejni.so
# SimpleJni.apk does not contain libglog.so

# check that the apk contains libsimplejni.so
if ! [[ $(unzip -l ${unsigned_apk} | grep lib/.*libsimplejni.so ) ]]; then
  echo "Could not find libsimplejni.so in SimpleJni's apk file: ${unsigned_apk}"
  exit 1

# check that the apk does not liblog.so
if [[ $(unzip -l ${unsigned_apk} | grep lib/.*liblog.so ) ]]; then
  echo "Found liblog.so in SimpleJni's apk file: ${unsigned_apk}. Since this is an NDK library, it should not be included."
