SQLCipher for Android currently includes support for
x86 only. At this time we do not include support for either
x86_64 as OpenSSL does not currently build on those platforms without modification of the standard OpenSSL build system. We currently expect OpenSSL to include support for
x86_64 with the 1.1.0 release, which is not yet available.
SQLCipher for Android will still run on Android devices that have 64 bit CPU's, however if you are using other third-party libraries that include native libraries that include either
x86_64, you may receive an error message like below:
Caused by: java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/xxx/base.apk"],nativeLibraryDirectories=[/data/app/xxx/lib/arm64, /vendor/lib64, /system/lib64]]] couldn't find "libstlport_shared.so"
Due to Android’s preferential loading process, if, for example, your APK is including other third-party libraries that contain native libraries that target architectures other than
x86, Android will attempt to load all native libraries from within the folder that is the closest match for its platform architecture, thus causing the error above when it attempts to locate SQLCipher for Android within a 64 bit platform folder.
This issue can be addressed by removing any included native libraries for architectures other than
x86; this allows the Android device to load the 32 bit version of all libraries, even on a 64 bit device. For gradle users, you can utilize the ABI split feature.
