無法啓動活動java.lang.RuntimeException

Question

我的android應用程序無法啓動活動，出於某種原因，活動的名稱是Caperucita，但我看不出是什麼問題，這是另一個這樣的活動運行完美，並且是Ricitos。也許你可以幫我

錯誤的logcat的：

Answer 1

看你的背景文件大小太大。嘗試在下面的相關佈局中移除背景屬性，然後查看是否會發生崩潰。

<RelativeLayout 
    android:id="@+id/rootRL" 
    android:layout_width="match_parent" 
    android:layout_height="262dp" 
    android:layout_alignParentBottom="true" 
    android:layout_alignParentTop="true" 
    android:layout_weight="0.83" 
    android:background="@drawable/caperucita_roja" 
    android:orientation="vertical" > 

要解決，你需要更多的內存的問題，或者你需要使用的要少。獲得更多內存並不是真的可行，但您可以指定更大的堆大小。在您的清單中，使用largeHeap屬性：

<application 
    android:allowBackup="true" 
    android:icon="@drawable/ic_launcher" 
    android:label="@string/app_name" 
    android:theme="@style/AppTheme" 
    android:largeHeap="true" > 

你可以閱讀更多關於該屬性here。

要減少所需的內存量，您需要減小該背景圖像的大小。我會考慮縮小該圖像的大小。如果不能縮小尺寸，請使用PNGCrush這樣的程序來優化圖像，這可以幫助減小文件的大小而不影響圖像的質量。 Here's a link to how to use PNGCrush from the command line.

Answer 2

您需要減少圖形文件的內存影響。從堆棧跟蹤中可以明顯看出，加載caperucita_roja背景時系統內存不足。 （該文件的大小爲480x3969，特別大，在內存中未壓縮將佔用7MB以上的空間，在很多設備上，這是應用程序可用內存總量的很大一部分。）請記住，Android設備在可用性方面受到很大限制記憶。
