Question

我创建了一个非常小的应用程序，只显示“Hello World”。主要活动调用加载SQLCipher库。

package companydomain.myapplication;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import net.sqlcipher.database.SQLiteDatabase;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        SQLiteDatabase.loadLibs(this);            // loading the SQLCipher libraries
    }
}

build.gradle（module：app）是：

apply plugin: 'com.android.application'

android {
    compileSdkVersion 25
    buildToolsVersion '25.0.0'

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 25
    }
    return void
}

dependencies {
    compile 'com.android.support:appcompat-v7:25.0.1'
    compile 'net.zetetic:android-database-sqlcipher:3.5.4@aar'
}

这个应用程序按预期工作但是，当我将Crashlytics添加到build.gradle时：

buildscript {
    repositories {
        maven { url 'https://maven.fabric.io/public' }
    }
    dependencies {
        classpath 'io.fabric.tools:gradle:1.+'
    }
}

apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

repositories {
    maven { url 'https://maven.fabric.io/public' }
}

android {
    compileSdkVersion 25
    buildToolsVersion '25.0.0'

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 25
    }
    return void
}

dependencies {
    compile 'com.android.support:appcompat-v7:25.0.1'
    compile 'net.zetetic:android-database-sqlcipher:3.5.4@aar'

    compile('com.crashlytics.sdk.android:crashlytics:2.6.5@aar') {
        transitive = true;
    }
    compile('com.crashlytics.sdk.android:crashlytics-ndk:1.1.5@aar') {
        transitive = true;
    }
}

crashlytics {
    enableNdk true
    androidNdkOut 'src/main/obj'
    androidNdkLibsOut 'src/main/libs'
}

一旦启动，应用程序崩溃并出现错误“java.lang.UnsatisfiedLinkError ...找不到”libsqlcipher.so“ - 我甚至没有从我的活动中调用Crashlytics。

这仅适用于x86_64和arm64_v8a ABI。在后一种情况下，错误列表包含“arm64_v8a”而不是“x86_64”

知道出了什么问题吗？提前谢谢，

Answer 1

自己找到答案。

SQLCipher显然不支持64位架构所以在build.gradle中我添加了一个abiFilter语句来排除64位架构：

...
android {
    compileSdkVersion 25
    buildToolsVersion '25.0.0'

    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 25

        ndk {
            abiFilters "armeabi", "armeabi-v7a", "x86", "mips"
        }
    }
    return void
}
....

不再崩溃了！

Answer 2

您还应该删除mips;适用于Android的SQLCipher目前仅包含armeabi，armeabi-v7a和x86的原生图书馆。

使用SQLCipher和Crashlytics for x86_64和arm84_v8a时，Android应用程序崩溃与UnsatisfiedLinkError
