MapFragment Google Maps API v2內存不足錯誤/內存泄漏

Question

過去幾天我已經閱讀了許多類似的帖子，但都沒有明確回答這個問題。經過2分鐘積極的地圖平移和混合地圖縮放後，我開始遇到OOM問題。該應用程序似乎在崩潰後仍保留在內存中，因爲在第一次失敗後需要較少的時間才能到達OOM。我將代碼縮小到只有一個帶有MapFragment的Activity，並且仍然獲得相同的OOM。我已經使用DDMS和MAT來嘗試和隔離問題，除了添加android:largeHeap="true"這隻會延遲OOM。屏幕重新定位不是問題，因爲我在我的清單中設置了android:screenOrientation="portrait"。任何幫助，將不勝感激。

更新2014年8月25日：This is supposed to be fixed back in May 2013?

更新2014年9月6日：仍然沒有成功，唯一的好選擇是使用Normal而不是Hybrid。 GC似乎能夠保持沒有圖像。

Answer 1

嘗試調用地圖的onPause，的onResume，在相應片段的方法onLowMemory。

Answer 2

我遇到了這個問題，試圖在演示模式下一次運行幾個小時的應用程序。無論我嘗試了什麼，30分鐘後，我都會看到這個崩潰，但沒有可讀的堆棧報告。

我嘗試了很多不同的東西，但這是唯一對我有用的東西。這不是修復地圖錯誤，但它保持我的應用程序崩潰：

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