尝试在谷歌地图V2安卓应用程序中获取空数组的长度

Question

我目前正在使用谷歌地图api开发一个Android应用程序,我有时会得到一个奇怪的崩溃(在我看来),因为没有明显的原因.这是崩溃日志:

            at com.google.maps.api.android.lib6.gmm6.o.cw.run(Unknown Source)

正如你所看到的,崩溃发生在谷歌api但代码已被混淆,所以我没有更多的信息,除了在第一行2:

final void put(short[] src, int srcOffset, int shortCount) {
    checkIsAccessible();
    int byteCount = checkPutBounds(SizeOf.SHORT, src.length, srcOffset, shortCount); // here is the error
    this.block.pokeShortArray(offset + position, src, srcOffset, shortCount, order.needsSwap);
    position += byteCount;
  }

@Override
    public ShortBuffer put(short[] src, int srcOffset, int shortCount) {
        byteBuffer.limit(limit * SizeOf.SHORT);
        byteBuffer.position(position * SizeOf.SHORT);
        if (byteBuffer instanceof DirectByteBuffer) {
            ((DirectByteBuffer) byteBuffer).put(src, srcOffset, shortCount);
        } else {
            ((ByteArrayBuffer) byteBuffer).put(src, srcOffset, shortCount);
        }
        this.position += shortCount;
        return this;
    }

有没有人遇到过这个bug？我究竟做错了什么 ？如果有人对此问题有所了解,我将很乐意与您讨论.

谢谢 !

您可能正在运行多个地图片段.请参阅我对目前困扰Google地图库的致命错误的撰写,涉及多个地图片段 - 以及我如何找到解决方法.
