Question

我想在我的必需品Qt项目中添加一个外部库，所以我将以下行添加到.pro文件中：

INCLUDEPATH + = $$ PWD / include

LIBS + = -L $$ PWD / shared / libs / armeabi -lopenal

但是，当我开始运行我的应用程序时，它无法启动：

D/dalvikvm( 3443): DexOpt: --- END 'QtIndustrius-14.jar' (success) ---

但是当我使用外部lib删除这些行和文件时，我的应用程序运行良好。我已经将libopenal.so推送到/ data / local / lib，并通过“export LD_LIBRARY_PATH = $ LD_LIBRARY_PATH：/ data / local / lib”将其添加到全局环境中

那么如何在项目中添加第三方库？以及如何将它们放入我的apk中？

Answer 1

在Eclipse中，单击“配置构建路径”，然后单击“添加JAR”，然后选择您的库。

将第三方库添加到必需的Qt项目中？
