java.lang.UnsatisfiedLinkError：dalvik.system.PathClassLoader崩溃应用程序

Question

我的应用程序崩溃了，在日志中我看到了：

java.lang.UnsatisfiedLinkError: dalvik.system.PathClassLoader[DexPathList[[zip file "/data/app/pl.pgo-1/base.apk"],nativeLibraryDirectories=[/data/app/pl.eltegps.pgo-1/lib/arm, /vendor/lib, /system/lib]]] couldn't find "libpackage.so"

在这行中我的apk崩溃了：

    System.loadLibrary("package");

这是我的全班

    private int fd;
    private int delay = 100;
    private static final String TAG = "serial_native";

        fd = openport(device);
        if (fd < 0) {
            Log.e(TAG, "native open returns null");
            return -1;
        }
        return 0;
    }
