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 .....这一行在Throwable t ....创建例外。我在HomeCardString.toString()中的数据非常大。记事本文件中大约1.9MB。我无法减少该数据的大小。该怎么办？

Answer 1

您可以尝试在清单中为您的应用设置android:largeHeap="true"。以下是参考资料：

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

如果这不起作用，请看一下这篇文章：

JAVA - Best approach to parse huge (extra large) JSON file

Answer 2

更改

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

到

        String res = responseString.length() > 160 
            ? responseString.substring(0, 40) + "..." : responseString;
        Log.e("My App", "Could not parse malformed JSON: \"" + res + "\":\n" + t.getMessage());

因为日志记录并不重要。
