Java Native Code Android应用程序

Question

我无法理解为什么我的应用程序给了我这个错误。

VuScreen.java在一个编译的jar文件中，我无法自由编辑，但Intellij的反编译器能够给我这个。

private static native void read(long var0, int var2, int var3, int var4, int var5, Buffer var6);

public void read(int x, int y, int width, int height, Buffer buffer) {
    read(this.getPtr(), x, y, width, height, buffer);
}

public void read(int x, int y, int width, int height, Bitmap bitmap) {
    ByteBuffer buffer = ByteBuffer.allocateDirect(this.getWidth() * this.getHeight() * 4);
    this.read(x, y, width, height, (Buffer)buffer);
    bitmap.copyPixelsFromBuffer(buffer);
}

我真的很困惑为什么会发生这种错误。它甚至可能是编译器问题。如果有帮助，我会使用IntelliJ。
