Missing dep libraries in generated apex

[Michael Goffioul]

Hi,

I'm trying to build Android Q (for android-x86, 32-bits) and I'm having a problem in the generated apex for com.android.media.swcodec, where there are a bunch of libraries missing in $TARGET_OUT/system/apex/com.android.media.swcodec/lib/.

The directory does contain various deps like libcode...@1.0.so, libmedia_codecserviceregistrant.so or libstagefright_amrnb_common.so. However it is missing some, most notably libstagefright_bufferqueue_helper.so or all libcodec2_soft_*.so modules. This then results in runtime errors when running mediaswcodec service.

What can be the reasons for deps to be missing from the apex?

Note that I tried to find my way in build/soong/, but didn't get anywhere in trying to debug this issue.

Michael.

Answering myself...

It turns out the reason the deps are not included in the APEX is the presence of cfi sanitizer in their Android.bp. When this is set, HideFromMake for the module is set to true, and the module is then not included when generating out/soong/Android-${TARGET_PRODUCT}.mk
