MapFragment Google Maps API v2内存不足错误/内存泄漏

时间：2014-08-27 17:21:01

标签： android out-of-memory google-maps-android-api-2

过去几天我读了很多类似的帖子，但没有一个专门回答这个问题。在使用混合地图进行约2分钟的积极地图平移和缩放后，我开始收到OOM问题。该应用程序似乎也在崩溃后保留在内存中，因为在第一次失败后到达OOM所需的时间更少。我将代码缩减为只有一个带有MapFragment的Activity，并且仍然获得相同的OOM。除了添加只延迟OOM的android:largeHeap="true"之外，我还使用了DDMS和MAT来尝试找出问题。屏幕重定向不是问题，因为我在我的清单中设置了android:screenOrientation="portrait"。任何帮助将不胜感激。

更新2014-08-25：This is supposed to be fixed back in May 2013?

更新2014-09-06：仍然没有成功，唯一不错的选择是使用Normal代替Hybrid。 GC似乎能够在没有图像的情况下跟上。

    if (mMap == null) {
        mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
        // Check if we were successful in obtaining the map.
        if (mMap != null) {
            // The Map is verified. It is now safe to manipulate the map.
            //startUsingMap();
            mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID);

2 个答案:

答案 0 :(得分：0)

在相应的Fragment方法中尝试调用map onPause，onResume，onLowMemory。

答案 1 :(得分：0)

我遇到了这个问题，试图在演示模式下运行应用程序一次几个小时。无论我尝试了什么，30分钟后，我都会看到这个崩溃没有可读的堆栈报告。

我尝试了很多不同的东西，但这是唯一对我有用的东西。它不是地图错误的修复程序，但它使我的应用程序不会崩溃：

    <application
    ...
    android:largeHeap="true">
