@ethiccode Are you working with a "legit" Facebook APK from the Google Play Store?

Whatever apk i choose it always come with unable to run dx....How to fix it...Plz help

dana-at-cp commented 7 years ago

Here's the code in backdoor-apk.sh that is relevant:

$DX --dex --output="$MY_PATH/$RAT_APK_FILE" $MY_PATH/bin/classes-processed.jar >>$LOG_FILE 2>&1
rc=$?
if [ $rc != 0 ]; then
  echo "done."
  echo "[!] Failed to run dx on proguard processed jar file"
  cleanup
  exit $rc
fi
echo "done."

The dx binary/utility is included with backdoor-apk.

DX=third-party/android-sdk-linux/build-tools/25.0.2/dx

Have you modified the original script at all?

I just tested v0.2.2 on a legit APK file and it worked fine.
