正如标题所说。

当我启动我的 Android 应用程序时,出现以下错误

No implementation found for void io.objectbox.BoxStore.nativeDelete(long)

我会稍微添加我的完整 build.gradle 和应用程序代码,因为我很着急,但我认为我应该发布,以防万一有一个已知且明显的解决方案。

我已经尝试过 1.1.0 和 1.2.0

更新:

一些进一步的信息。我正在尝试在我的 LibGDX 项目中使用 ObjectBox。 LibGDX 是一个跨平台的游戏库,你用 Java 编写代码,它有 Android、iOS 和桌面版本。

我没有使用 ObjectBox 的 Android 实现,而是决定尝试使用 Java 版本,这样理论上它可以在所有三个平台上使用。我不确定,但也许这就是问题所在。使用 Java 版本,但在 Android 平台上。

使用 ObjectBox 的数据库类

private void createMyObjectBox() throws IOException {
File tempFile = File.createTempFile("objectstorefile", "");
tempFile.delete();
boxStoreDir = tempFile;
Gdx.app.error("DB","tempfile="+tempFile);
Gdx.app.error("DB","boxstoredir="+boxStoreDir);
store = MyObjectBox.builder().directory(boxStoreDir).build();
}

最佳答案

如果我没记错的话,您只需要在 Java 项目中定义 ObjectBox 依赖项。似乎缺少的是 Android 特定的 Artifact :

compile "io.objectbox:objectbox-android:$objectboxVersion"

这包括共享库( native .so 文件)。

其他说明:

  • 确保您的所有库都具有一致的 ABI 支持。看起来你的 LibGDX 带有 armeabi,它很旧,因此不包含在 ObjectBox 中。 ObjectBox Android 附带 armeabi-v7a、arm64-v8a 和 x86 支持。我建议从您的 LibGDX 设置中删除所有其他人。否则,该应用可能会在某些设备上崩溃,因为它无法混合使用 32 位和 64 位库。
  • 您可以通过将 compile "io.objectbox:objectbox-linux:$objectboxVersion" 添加到您的 Linux 机器的桌面项目来尝试桌面版 ObjectBox
  • 您使用的 ObjectBox 版本已过时。请查看 changelog获取最新版本。
