我不知道为什么会出现这个错误。我见过lib文件夹，里面有libitv.so文件。我也试过

static {
         try {
             System.loadLibrary("itv");
           // System.load("/data/data/com/example/lib/itv.so");
         }
         catch (UnsatisfiedLinkError use) {
                Log.e("JNI", "WARNING: Could not load itv.so");
            }
        }

但得到同样的错误。任何人都可以告诉我这个错误的解决方案。先谢谢你。

Answer 1

如果库名为libitv.so，则会被识别，并在构建.apk之前放在应用程序目录的libs \ armeabi目录中。

有时，如果未完全复制库（部分复制），由于某些系统问题，也无法识别部分库。

Answer 2

尝试命名实际文件libitv.so（lib + library name + .so）并将其放在libs目录的armeabi文件夹中

java.lang.ExceptionInInitializerError由以下引起：java.lang.UnsatisfiedLinkError：找不到库
