尝试获取谷歌地图V2安卓应用程序中空数组的长度

Question

我目前正在使用谷歌地图api开发一个android应用程序，我有时会遇到奇怪的崩溃(在我看来)，原因并不明显。这是崩溃日志：

12-02 16:38:57.071  20796-21137/com.appsolute.ParkYoo E/AndroidRuntime﹕ FATAL EXCEPTION: GLThread 4623
    Process: com.appsolute.ParkYoo, PID: 20796

            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google api中，但代码已经被混淆了，所以除了前两行之外，我没有更多的信息：

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;
    }

有没有人已经遇到过这个bug？我做错了什么？如果任何人对这个问题有见解，我很乐意讨论它。

谢谢！

您可能正在运行多个map片段。请参阅我关于当前困扰Google Maps库的致命bug的文章，涉及多个地图片段-以及我是如何找到解决办法的。

Google is currently working on the case，并将其优先用于下一版谷歌Play服务！
