android12 32位版本预置apk

Android.mk 如下所示

LOCAL_PATH:= $(call my-dir)
$(shell mkdir -p $(TARGET_OUT)/app/Facebook/)
$(shell cp -rf $(LOCAL_PATH)/lib  $(TARGET_OUT)/app/Facebook/)
$(shell cp -rf $(LOCAL_PATH)/Facebook.apk $(TARGET_OUT)/app/Facebook/Facebook.apk)

遇到了2个问题。
1.签名异常
使用 LOCAL_CERTIFICATE := PRESIGNED 编译后的apk签名异常。

apksigner verify --print-certs Facebook.apk 
DOES NOT VERIFY
ERROR: JAR signer FACEBOOK.RSA: JAR signature META-INF/FACEBOOK.SF indicates the APK is signed using APK Signature Scheme v2 but no such signature was found. Signature stripped?

解决方法是使用cp的到目录下的方式去安装，不编译。
2.找不到so。

E/AppInitScheduler|Run: Exception in InitSharedLibraries
com.facebook.soloader.SoLoaderDSONotFoundError: couldn't find DSO to load: libsuperpack-jni.so
existing SO sources:
SoSource 0: ApplicationSoSource[DirectorySoSource[root = /system/app/Facebook/lib/arm flags = 1]]
SoSource 1: DirectApkSoSource[root = [/system/app/Facebook/Facebook.apk!/lib/armeabi-v7a]]
SoSource 2: DirectorySoSource[root = /vendor/lib flags = 3]
SoSource 3: DirectorySoSource[root = /system/lib flags = 3]
Native lib dir: /system/app/Facebook/lib/arm

这个需要把lib下的armeabi-v7a（apk改zip后缀解压后的lib目录下的文件是armeabi-v7a）改名为arm。它找不到arm会报错。

目录层级如下所示。
