viewflipper不適用於4.0

Question

我已經開發出適用於Android 2.1版本的罰款，但是當我啓動它在Android 4.0版本，它不運行，並拋出堆棧跟蹤這樣的應用程序：

我只是不明白爲什麼會發生這種情況，因爲相同的程序在Android 2.1版本上運行完美，但在4.0版本上拋出outOfMemoryError。請幫助，如果你有一些想法..

Answer 1

如果您從UI線程解碼一個位圖，可能會出現outOfMemoryError。嘗試將您的解碼流更改爲asynTask。

Answer 2

與Anis所說的不同，在不同的線程上解碼yor位圖不會幫助您避免內存不足（OOM）錯誤，您仍然將相同數量的數據加載到應用程序中。

您需要縮小圖片的大小或縮小圖片的大小，以免加載所有數據，有關此信息的更多信息請參閱Loading Large Bitmaps Efficiently。
