android - 尝试在谷歌地图 V2 android 应用程序中获取空数组的长度

Question

我目前正在使用 google maps api 开发一个 android 应用程序，我有时会无缘无故地发生奇怪的崩溃(在我看来)。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)

如您所见，崩溃发生在 google api 中，但代码已被混淆，因此除了前 2 行之外，我没有更多关于此的信息:

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;
    }

有没有人遇到过这个错误？我究竟做错了什么 ？如果有人对此问题有见解，我很乐意讨论。

谢谢!

您可能会运行多个 map fragment 。请参阅我关于目前困扰 Google map 库的这个 fatal error 的文章，涉及多个 map fragment - 以及我如何找到解决方法。

Google is currently working on the case并将其优先用于 Google Play 服务的下一个版本!
