Android - OutOfMemoryError同時膨脹類com.hultan.formler.ResizableImageView

我最近修改了我的應用程序。我添加了大約30個不同的片段（但不多於2個同時使用）。我不知道這是否會消耗內存並導致問題。無論如何，應用程序崩潰時，我打開這個片段。我用日誌來找出問題所在。但我不知道什麼的問題是。Android - OutOfMemoryError同時膨脹類com.hultan.formler.ResizableImageView

惱人的是，這個確切的代碼工作，我加入之前完全正常的30幾乎相同fragments（這是一個導航，帶你到這個特定的片段）從未被使用過。

看到錯誤'java.lang.OutOfMemoryError' ...我想你使用的是高分辨率的'Bitmap' ... –

@GopalRao所以我使用的圖像應該更小？ – HultBullt

是的...嘗試使用更小的「位圖」或9貼片圖像... –

@GopalRao解決了問題！我的圖像顯然太大了。我將它們全部調整到大小的40％，現在它工作得很好！
