Couldn't load stlport_shared

[Swarnamahesh]

Thank you for providing an open source project for protecting the database, as security is a very important feature in my app. I added the jars and so files as mentioned in the installation guide and made the code changes, but I am getting the following error in loadlibs. Can you please help me with this issue.

Why is it not able to load stlport_shared, should i do any specific compilation for the so files?

Hi Swarnamahesh,

You will need to copy the libstlport_shared.so file from the libs/armeabi folder into your application's libs/armeabi folder. Can you check for that and move the file if it's not present?

Also, please provide us information on your OS and device type.

Yes I did add the libstlport_shared.so file in the lib/armeabi folder.
I am developing in windows 7, eclipse helios and i tested on Motorola Fire XT311 (Android 2.3.4),
LG P500 (Android 2.3.3), also tried it on Google API 8 emulator (Android 2.2), crashed on all 3.

[n8fr8]

it is "libs/armeabi" not "lib". Plural, with an S. :)

[Swarnamahesh]

yes, my oversight. It works perfectly now. Thanks for the help.

Just an afterthought, I am able to use this only if the db is in external memory, can I create/open db from internal memory and still keep it encrypted?

i copy libstlport_shared.so file into my application lib/armeabi folder but still give error message like Couldn't load stlport_shared.so file.

Hi harshal111,

The libstlport_shared.so file needs to be located within the libs directory, not lib.

[willli666]

If your app is to be installed as a system app, the .so files need to be copied into /system/lib/ folder. Otherwise, it will give you this error.

Hi sulochanansk,

Is your application being installed as a system application, versus being installed within the /data partition? Also, please verify with apktool that you are in fact bundling stlport_shared.so.

[sulochanansk]

it is installed as a system application. i have checked with apktool . here is the list of all so files of .apk file.

lib/armeabi/libdatabase_sqlcipher.so
lib/armeabi/libsqlcipher_android.so
lib/armeabi/libstlport_shared.so
lib/armeabi/libblank.so
lib/armeabi-v7a/libaurasma_cpufeatures.so
lib/armeabi-v7a/libgnustl_shared.so
lib/armeabi-v7a/libtracker.so
lib/armeabi-v7a/libtracker_neon.so
lib/x86/libblank.so

only stlport_shared.so lib is not loading while creating database. is there any other proceess ti load .so files in case of new Android versions.

Hi sulochanansk,

Could you try the recommendation here?
