无法阅读libvlcjni.so;无法检查设备ABI

Question

我按照here的程序编译了libVlc for android。编译的项目在eclipse中没有显示任何错误，但是当我在设备上运行时，它会抛出以下错误

05-21 14:37:50.834: D/dalvikvm(14423): GC_CONCURRENT freed 181K, 8% free 9633K/10439K, paused 17ms+7ms, total 62ms

请提前帮助我解决问题

Answer 1

您收到此错误是因为您没有导出设备的abi，如说明中所述。我将假设您也没有按照文档中的“环境设置”部分进行操作。所以，做如下：

确保已下载NDK，然后在终端中运行此（带路径）：

  

导出ANDROID_NDK = / path / to / android-ndk＆gt;

然后，编译.sh文件并导出您的设备（或模拟器的abi）。由于脚本处理abi，因此.sh文件的编译直接链接到abi问题。您可以在脚本代码（compile.sh）中看到这一点：

# try to detect NDK version
REL=$(grep -o '^r[0-9]*.*' $ANDROID_NDK/RELEASE.TXT 2>/dev/null|cut -b2-)
case "$REL" in
    9*)
        GCCVER=4.8
        CXXSTL="/"${GCCVER}
    ;;
    8?*)
        # we don't use 4.4.3 because it doesn't handle threads correctly.
        # TODO : clang?
        if test -d ${ANDROID_NDK}/toolchains/arm-linux-androideabi-4.7
        # if gcc 4.7 is present, it's there for all the archs (x86, mips, arm)
        then
            # since r8d
            GCCVER=4.7
        else
            GCCVER=4.6
        fi
        CXXSTL="/"${GCCVER}
    ;;
    7|8|*)
        echo "You need the NDKv8b or later"
        exit 1
    ;;
esac

export GCCVER
export CXXSTL

# Set up ABI variables
if [ ${ANDROID_ABI} = "x86" ] ; then
    TARGET_TUPLE="i686-linux-android"
    PATH_HOST="x86"
    HAVE_X86=1
    PLATFORM_SHORT_ARCH="x86"
elif [ ${ANDROID_ABI} = "mips" ] ; then
    TARGET_TUPLE="mipsel-linux-android"
    PATH_HOST=$TARGET_TUPLE
    HAVE_MIPS=1
    PLATFORM_SHORT_ARCH="mips"
else
    TARGET_TUPLE="arm-linux-androideabi"
    PATH_HOST=$TARGET_TUPLE
    HAVE_ARM=1
    PLATFORM_SHORT_ARCH="arm"
fi

我建议再次阅读Android Compile文档，并按照说明一步一步。

如果您使用的是Android Studio，请将*.so移至src/jniLibs/armeabi-v7a
