Android 应用程序中的 java.lang.OutOfMemoryError

Question

        try {       
            Gson gson = new Gson();
            try
            {
                ((ProfileActivity)getActivity()).interactionResult = gson.fromJson(HomeCardString.toString(), InteractionSummaryResult.class);

            }
            catch(Exception e)
            {
                Log.i("myyyy", e.getMessage());
                e.printStackTrace();
            }

        } catch (Throwable t) {
            Log.e("My App", "Could not parse malformed JSON: \"" + responseString + "\"" + t.getMessage());
        }

gson.fromgson..... 此行在 Throwable t .... 处创建异常。我在 HomeCardString.toString() 中的数据非常大。记事本文件大约 1.9MB。我无法减少该数据的大小。该怎么办？

您可以尝试在 list 中为您的应用程序设置android:largeHeap="true"。引用如下:

http://developer.android.com/reference/android/R.styleable.html#AndroidManifestApplication_largeHeap

如果这不起作用，请查看这篇文章:
