Hi, I’m trying to use SQLCipher in Android Studio following your instruction but once the program reaches `SQLiteDatabase.loadLibs(this);` it fails both on x86 emulator and on my physical device (Xiaomi Mi4). Device error output: ``` 01-26 20:56:42.850 12905-12905/com.btcontract.wallet E/dalvikvm: ERROR: couldn't find native method 01-26 20:56:42.850 12905-12905/com.btcontract.wallet E/dalvikvm: Requested:

Can you please verify your apk is properly including the SQLCipher for Android native libraries? You can dump the packaged content of the apk with [apktool](http://ibotpeaches.github.io/Apktool/). ---

Sure, here’s how it looks: ``` anton@anton-VPCCW2S1R:~$ tree '/home/anton/app-debug/lib' /home/anton/app-debug/lib ├── armeabi │ ├── libdatabase_sqlcipher.so │ ├── libscrypt.so │ ├── libsqlcipher_android.so │ └── libstlport_shared.so ├── armeabi-v7a │ ├── libdatabase_sqlcipher.so │ ├── libscrypt.so │ ├── libsqlcipher_android.so │ └── libstlport_shared.so ├── x86 │ ├── libdatabase_sqlcipher.so │ ├── libscrypt.so │ ├── libsqlcipher_android.so │ └── libstlport_shared.so └── x86_64 ├── darwin │ └── libscrypt.dylib ├── freebsd │ └── libscrypt.so └── linux └── libscrypt.so 7 directories, 15 files ``` ---

Hi @anton.kumaigorodskiy The reason you are likely receiving this issue is that SQLCipher for Android is only built for armeabi, armeabi-v7a, and x86 platforms. You are likely deploying to a x86\_64 device so Android uses the corresponding folder for resolving all native libraries (i.e., x86\_64), as such the SQLCipher for Android binaries are not present in your x86\_64 folder. A work around is to remove the x86\_64 native libraries entirely, it should fall back to x86 folder for x86\_64 devices. ---

Thanks for suggestions! The issue was not there, however, it was that I have `minifyEnabled true` in Gradle settings and it looks like ProGuard was cutting some `net.sqlcipher.*` classes off. Adding the following to ProGuard settings solved the problem: ``` -keep class net.sqlcipher.** { *; } -dontwarn net.sqlcipher.** ``` ---

Hello @anton.kumaigorodskiy Great, I’m glad to hear you were able to solve the issue! Please note, you will see the issue I describe above on an x86\_64 device so you may consider adjusting for that as well. ---

Can You share whole code of gradle to resolve above issues? ---

Hi, I am new to SQLCipher, I just started integrating it to some messed up SQLite project and I could not understand even a thing. Zygote’s thread crashed with really large log and I freaked out. I really appreciate you sharing that, you saved my day or even a week figuring that out. So this worked for me but I guess proguard rules also working. Now it works out of the box as expected with just small hacks in the code. > buildTypes { > release { > shrinkResources false > minifyEnabled false > proguardFiles getDefaultProguardFile(‘proguard-android.txt’), ‘proguard-rules.pro’ > } > debug { > shrinkResources false > minifyEnabled false > proguardFiles getDefaultProguardFile(‘proguard-android.txt’), ‘proguard-rules.pro’ > } > } I suppose you should add that gradle stuff to main howto on github page cause that’s really confusing issue. ---

Hi @POMATu Thank you for the feedback, we will consider integrating ProGuard into the library build itself.
