JNI_OnLoad返回的错误版本（-1） [英] JNI_OnLoad returned bad version (-1)

问题描述

我试图加载Qt5Core库在我的Andr​​oid应用程序，我得到这样的：

I'm trying to load the Qt5Core library in my Android application and I get this:

JNI_OnLoad returned bad version (-1) in /data/data/com.xxx.yyy/lib/libQt5Core.so 0x41a8f3c0
Failed to load library : Qt5Core due to link error unknown failure
java.lang.UnsatisfiedLinkError: unknown failure
at java.lang.Runtime.loadLibrary(Runtime.java:370)

这是如何我试图加载的方式：

This is the way how I'm trying to load it:

的System.loadLibrary（S）;

System.loadLibrary(s);

其中S是包含几个库名字的数组。其他库加载正确..

where "s" is an array containing several library names. The other libraries are loaded correctly..

任何想法，欢迎！

所以我得到这个第一：

D / dalvikvm（11445）：试图加载LIB
  /data/app-lib/com.xxx.yyy/libQt5Core.so 0x42666fd8结果
  D / dalvikvm（11445）：添加共享库
  /data/app-lib/com.xxx.yyy/libQt5Core.so 0x42666fd8

D/dalvikvm(11445): Trying to load lib /data/app-lib/com.xxx.yyy/libQt5Core.so 0x42666fd8
D/dalvikvm(11445): Added shared lib /data/app-lib/com.xxx.yyy/libQt5Core.so 0x42666fd8

E / LibrariesLoader（11445）：无法加载库：Qt5Core由于链路
  错误JNI_ERR从JNI_OnLoad在返回
  /data/app-lib/com.xxx.yyy/libQt5Core.so

E/LibrariesLoader(11445): Failed to load library : Qt5Core due to link error JNI_ERR returned from JNI_OnLoad in "/data/app-lib/com.xxx.yyy/libQt5Core.so"

E / LibrariesLoader（11445）：java.lang.UnsatisfiedLinkError中：JNI_ERR
  从JNI_OnLoad在/data/app-lib/com.xxx.yyy/libQt5Core.so

E/LibrariesLoader(11445): java.lang.UnsatisfiedLinkError: JNI_ERR returned from JNI_OnLoad in "/data/app-lib/com.xxx.yyy/libQt5Core.so"

......再有就是它没有任何错误/警告加载另一个库。该库有Qt5Core.so的依赖关系。

...then there is another library which is loaded without any error/warning. That library has Qt5Core.so as dependency.

我已经调查和我得到，因为以下code这个JNI_ERR：

I have investigated and I'm getting this JNI_ERR because of the following code:

如果（VM-> GETENV（安培;！uenv.venv，JNI_VERSION_1_6）= JNI_OK）结果
          返回JNI_ERR;

if (vm->GetEnv(&uenv.venv, JNI_VERSION_1_6) != JNI_OK)
return JNI_ERR;

这是我使用的JNI的版本是1.6 !!!!

The version of JNI that I'm using is 1.6!!!!

推荐答案

在启动时，如果未找到返回JNI_ERR QtCore的JNI_OnLoad加载名为QtNative的活动。

QtCore's JNI_OnLoad loads an activity called "QtNative" when it starts and returns JNI_ERR if it is not found.

QtNative在QtAndroid-bundled.jar中定义。您可以在QT 5.3 SDK文件夹中找到它：
     QT5 / 5.3 / android_armv7 /罐/ QtAndroid-bundled.jar

QtNative is defined in "QtAndroid-bundled.jar". You can find it in your QT 5.3 SDK folder: Qt5/5.3/android_armv7/jar/QtAndroid-bundled.jar

只需添加到您的项目的库文件夹中。

Just add this to your project's "libs" folder.
