Memory Footprint Evaluator - Cannot invoke "java.io.InputStream.readAllBytes()"

[Chippi]

I've been trying to fix this issue for a long time, but I'm out of ideas.

Java version java 17.0.12 2024-07-16 LTS

I've built the memory footprint tool using ./gradlew :memory-footprint:jar.

Then I've tried to run the command for my own watch face format apk and also for samples in https://github.com/android/wear-os-samples/tree/main/WatchFaceFormat. The APK's was built using the command ./gradlew assembleDebug

java -jar ./memory-footprint.jar --watch-face app-debug.apk --schema-version 2 --ambient-limit-mb 10 --active-limit-mb 100 --apply-v1-offload-limitations --estimate-optimization

But I always get this error.

Starting memory footprint test with app-debug.apk

I cannot figure out what's wrong, I'd appreciate any help.

Try release.aab and then use a memory-footprint for it. I'm not sure if memory-footprint is intended to work with .apk files.

Thanks for your suggestion @amoledwatchfaces.

For me, it didn't work with .aab bundle either.

java -jar ./memory-footprint.jar --watch-face app-release.aab --schema-version 2 --ambient-limit-mb 10 --active-limit-mb 100 --apply-v1-offload-limitations --estimate-optimization

Starting memory footprint test with app-release.aab
Test report:
[MEMORY_FOOTPRINT]: �??FAIL�?? Asset @drawable/minute_hand was not found in the watch face package �??

[amoledwatchfaces]

@Chippi This output is correct. Now you need to resolve issue within your watch face package.

1. how are you referencing minute_hand in your watchface.xml?
2. is the minute_hand drawable.xml or png?
3. is minute_hand resource really in the package?

1.

            <MinuteHand
                height="150"
                pivotX="0.5"
                pivotY="1"
                resource="@drawable/minute_hand"
                width="10"
                x="220"
                y="75" />

2. It's a png, minute_hand.png placed in the drawable folder

3. Here's a snapshot of my release aab bundle.

Is it possible to share the watch face? If you'd prefer not to post it could you share it with me directly? (garan@google.com)

1.

            <MinuteHand
                height="150"
                pivotX="0.5"
                pivotY="1"
                resource="@drawable/minute_hand"
                width="10"
                x="220"
                y="75" />

Here, change it to resource="minute_hand" (do not use @drawable) What do you think @garanj ?

Yes, good spot @amoledwatchfaces !

2 days of struggle and you solved it, now it works. Thank you so much! @amoledwatchfaces

I got it from this example. Never realised it was wrong since it works fine on the wear os android emulator. https://github.com/android/wear-os-samples/blob/81c6e335718119f0c762b4c5d42f3d39af461d74/WatchFaceFormat/SimpleAnalog/watchface/src/main/res/raw/watchface.xml

Perfect!

@garanj maybe I can create PR to remove those @drawable references in the sample?

Ouch! yes please!

The tool is documented here to work on .apk but indeed seems to work only on .aab. Could I suggest that the documentation be updated?
