    Just ran isprelinked on libwebcore.so to confirm my suspicions that the Liquid E Android build configuration is similar to that of the Huawei Ideos S7.

    ./libwebcore.so: 0x6a000000


    I'm not an AOSP dev, but would the build notes here will thus apply?
    Did anyone successfully built Android from sources? - Android @ MoDaCo

    Changes will have to be made to prelinkmap to make various things work as desired.

    The kernel is missing the highmem patch, and needs config VMSPLIT_2G


    Would this also mean that the Acer Liquid E Froyo might be able to run unmodified on the Huawei S7 (for the most part, anyways)?

    Just as proof of concept, you can enable animated GIF files and V8 webkit for Android 2.1 simply by taking the libwebcore.so from the following Acer Liquid ROM:
    http://code.google.com/p/acer-liquid-community-rom-bugtracker/downloads/list
    LCR-E_1.8.2.2-signed.zip

    (I built the optimized libwebcore for them at one point as proof on concept, so I remember)

    Can we change the lockscreen by replacing a lib?

    Not everything may match. Tried pushing some other libs that did not work. I guess someone has to run isprelinked on all the libs to check

    I checked that too. So must have been something else causing it not to boot. Does not really mean anything.

    But the VMSPLIT does affect whether or not a built image will boot, I recall.

    More references:

    https://www.codeaurora.org/gitweb/q...ff;h=ff9c9dbb383a6b39529730fc5ae3a7ef4b2cb9bb

    If pulling Android was not so painfully slow, I would have pulled CodeAurora's Eclair and Froyo for testing...
