ParseRequestException: i/o failure in ParseDecompressInterceptor on 1.12.0 on API<19 devices

[aphexcx]

I (and other developers) are getting errors with 1.12.0 on older devices (seemingly API 19 and below). http://stackoverflow.com/questions/34561280/android-parse-sdk-i-o-failure-unknown-format-magic-number-227b

My stacktrace, from an API 18 device:

Seems to be similar to #325.

Hi @aphexcx, could you try ParseLogInterceptor and paste your request here?

[aphexcx]

Added it (version 0.0.2) and the problem went away. Very strange how adding the interceptor made the query work, like what happened to the guy in #326. I expected it to still fail, but show some additional logging.

Here's the ParseLogInterceptor log. As you can see, the query succeeds after a few errors (looks like it retries):

Should be noted that like in #326 (comment), I'm also trying to query for 9 items and running into failure. Weird edge case!

Having the same issue testing with a Samsung Galaxy S2. API 16.
Fixed when going back to version 1.11

Hi @aphexcx, I can repo this issue. It seems like a valid bug. I will dig into this issue and update the status.

[wangmengyan95]

The cause of this problem is related gzip response stream. There are two reasons:

1. In 1.12.0, we introduce a new way to initialize Parse. However, we introduce a bug for that feature. Previously, we only add ParseDecompressInterceptor when developers add external ParseNetworkInterceptor. However, in 1.12.0, we always add ParseDecompressInterceptor. ParseDecompressInterceptor is used for decompressing the gzip response stream. It will check the response header Content-Encoding and decompress if necessary.
2. For Android API >= 19 version, we use URLConnection which is powered by OKHttp internally. When the response is a gzip stream, the libraries will automatically unzip the stream and remove the hear Content-Encoding: gzip.
   For Android API < 19, we use ApacheHttp internally. When the response is a gzip stream, we unzip the stream but we do not remove the header Content-Encoding: gzip.

Thus, in 1.12.0, when we use ApacheHttp, since we always have ParseDecompressInterceptor, we will unzip the gzip response stream twice which will throw the exception at the second time.
For ParseLogInterceptor, the interceptor will unzip the stream and remove the header Content-Encoding, thus, when we use the interceptor to check the request and response, this issue is gone.
It seems #346, #326 are all related to this bug.
