Question

我在我的项目中使用SQLCipher作为数据库。我的应用程序在OS棒棒糖及以上的手机中成功运行。但有OS 4.4.4及以下版本的问题。我正在使用SQLCipher jar文件（不是最新的）。在应用程序启动时，我收到以下错误：

04-26 12:50:04.940 18598-18598/packageName E/dalvikvm: Could not find class 'net.sqlcipher.database.SQLiteCompiledSql', referenced from method net.sqlcipher.database.SQLiteDatabase.deallocCachedSqlStatements

    SharedPreferences preferences = PreferenceManager.getDefaultSharedPreferences(getContext());
    try {

      SQLiteDatabase.loadLibs(getContext());

      if (preferences.contains(Constants.OLD_USER_PIN_SET)) {
        if (preferences.contains(Constants.REKEY) && preferences.getBoolean(Constants.REKEY,
            true)) {
          password = getPassword();
        } else {
          password = getOldPassword();
        }
      } else {

      }
      if (password != null) db = mOpenHelper.getWritableDatabase(password);
    } catch (SQLiteException e) {
      e.printStackTrace();
    }
    return db != null;
  }

错误发生在代码中的此位置

SQLiteDatabase.loadLibs(getContext());

我做了足够的研究，但无法解决问题。请帮助我。谢谢。

Answer 1

在我的情况下，删除multidex是不切实际的，但是使用gradle的multiDexKeepFile属性找到了解决方案。当您违反64K方法限制时，这会将指定的类包含在第一个dex中。

在app/build.gradle中，指向multiDexKeepFile：

// Enabling multidex support. 
multiDexEnabled true 
multiDexKeepFile file('multidex.keep')

在保存文件中，指定您需要包含在第一个dex中的类，在我的例子中是我的内容提供者和sqlcipher的SQLiteDatabase：

com/myapp/android/database/provider/MyContentProvider.class
net/sqlcipher/database/SQLiteDatabase.class

这停止了物理S3 mini和Nexus 4虚拟设备（两者都是api 16，在修复之前都崩溃）的崩溃。

Answer 2

听起来好像本机库可能未包含在您的构建中。最简单的解决方案可能是您只需使用我们提供的AAR分发：

compile 'net.zetetic:android-database-sqlcipher:3.4.0@aar'

Answer 3

最后，经过大量研究，我得到了解决问题的方法。当我添加

时，问题就出现了

compile 'com.google.android.gms:play-services:8.4.0'

我的项目中的地图。这不是必要的。当我添加这个时，我得到一个错误，说方法计数超过64K限制。所以我添加了

`multiDexEnabled true`

我的app/build.gradle中的

还有一些错误。当我搜索时，我必须添加

 dexOptions {
    javaMaxHeapSize "4g"
  }

进入app/build.gradle。在棒棒糖和以上操作系统的手机中没有更多的错误。但对于其他人，我遇到了上述问题。

所以我通过改变

来修复它

compile 'com.google.android.gms:play-services:8.4.0'

到

 compile 'com.google.android.gms:play-services-location:8.4.0'
 compile 'com.google.android.gms:play-services-maps:8.4.0'
 compile 'com.google.android.gms:play-services-appindexing:8.4.0'

所以这些方法没有超过64K的限制。问题解决了。谢谢大家的时间。

Answer 4

如果你可以删除：

multiDexEnabled true

致命异常：主要java.lang.VerifyError：来自SQLCipher的net / sqlcipher / database / SQLiteDatabase
