After call SQLiteDatabase.loadLibs(mContext), throw exception SIGILL (signal SIGILL: illegal instruction)

[Lurkyli]

Expected Behavior

I want to integrate android-database-sqlcipher:4.4.3 into my smart TV app, and it works fine on android 4.4.2.

Actual Behavior

After SQLiteDatabase.loadLibs(mContext) was called, the exception SIGILL (signal SIGILL: illegal instruction) was thrown on an android 4.4.2 TV.

Steps to Reproduce

1. Integrate android-database-sqlcipher:4.4.3 into a app;
2. Launch the app on android 4.4.2 smart TV.

SQLCipher for Android version:
android-database-sqlcipher:4.4.3

Are you able to reproduce this issue within the SQLCipher for Android test suite?
No, but I meet the follow test failed:

Hi @Lurkyli

It appears your Android TV is running Android OS 4.4.2, correct? That is API 19, however, Android Studio only offers down to API 21 when creating Android TV emulator's. I was unable to boot an Android TV emulator running API 21, however, I was able to run our test suite successfully on an Android TV emulator running API 22.

Are you able to run either your application, or the test suite on other Android OS TV versions, or are you limited to Android OS 4.4.2?

[Lurkyli]

Android-database-sqlcipher:4.4.3 works fine on other smart TV, eg: android 5.1/8.0 and another 4.4.4(api 19). I think my project maybe have some different config among them, and I'm investigating it.

[Lurkyli]

After I added my native module code into the sqlcipher-android-tests-master demo project, the issue was reproduced.
There are the build.gradle files:
The build.gradle in app module:
apply plugin: 'com.android.application'

android {
compileSdkVersion 30
buildToolsVersion "30.0.3"

defaultConfig {
applicationId "net.zetetic.sqlcipher.test"
minSdkVersion 19
targetSdkVersion 30
versionCode 500000
versionName "5.0.0"
ndk {
// 设置支持的SO库架构
abiFilters 'armeabi-v7a'
}
}
buildTypes {
release {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
debug {
minifyEnabled false
proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}
}
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
}

dependencies {
// For testing JAR-based distribution:
// implementation files('libs/sqlcipher.jar')

// For testing local AAR packages:
//implementation (name: 'android-database-sqlcipher-4.4.3-release', ext: 'aar')

// For testing on remote AAR references:
implementation 'net.zetetic:android-database-sqlcipher:4.4.3@aar'

implementation "androidx.sqlite:sqlite:2.0.1"

// For Room tests:
implementation "androidx.room:room-runtime:2.1.0"
annotationProcessor "androidx.room:room-compiler:2.1.0"
}

The build.gradle in my native module:
plugins {
id 'com.android.library'
}

android {
compileSdkVersion 30
buildToolsVersion "30.0.3"

defaultConfig {
    minSdkVersion 19
    targetSdkVersion 30
    versionCode 1
    versionName "1.0"

    testInstrumentationRunner "androidx.test.runner.AndroidJUnitRunner"
    externalNativeBuild {
        cmake {
            cppFlags ""
            abiFilters 'armeabi-v7a'
        }
    }
}

buildTypes {
    release {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
    debug {
        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
    }
}

externalNativeBuild {
    cmake {
        path "src/main/cpp/CMakeLists.txt"
        version "3.10.2"
    }
}

compileOptions {
    sourceCompatibility JavaVersion.VERSION_1_8
    targetCompatibility JavaVersion.VERSION_1_8
}

}

dependencies {

implementation 'androidx.appcompat:appcompat:1.1.0'
implementation 'com.google.android.material:material:1.1.0'
testImplementation 'junit:junit:4.+'
androidTestImplementation 'androidx.test.ext:junit:1.1.1'
androidTestImplementation 'androidx.test.espresso:espresso-core:3.2.0'

}

If I disabled the native build in my native module, it's ok.

Have you the debug release aar? I want to catch more detail log.

Thanks!

[Lurkyli]

I think it's a debug environment issue, and the Android-database-sqlcipher works well on release environment.
The issue duplicate with #269.

Thanks!

Hi @Lurkyli

Thank you for the update, we are happy to hear SQLCipher for Android is working well for you.
