Error in Apk generated from BASE_URL in config.json

[shreyasnbhat]

I am building an script to generate apks of different sample via travis. As of now the only apk in the apk branch is of the fossasia17 sample. Now we are going to have multiple sample apks in the apk branch after each build.

The Google I/O 2016 version gave me several errors.

I think that that some formatting errors have cropped up in the sample probably. And these errors are shown by the ResponseProcessor.
@iamareebjamal Please have a look.
@arp95 @mahikaw Please test the app by changing the BASE_URL in config.json to the ones in Google I/O 17 etc.

This is because a new line is used without \n

"short_biography": "<p>Yigit is a software engineer on the Android Framework team focusing on app architecture and developer productivity. He also works on Data Binding and RecyclerView. Prior to joining Google, he was the Android Engineering Manager at Path.
 He received his bachelor's degree in computer engineering from Middle East Technical University, Turkey.</p>"

You can add lenient parsing by

mapper.configure(Feature.ALLOW_UNQUOTED_CONTROL_CHARS, true);

in the app

@iamareebjamal any updates on this?

[iamareebjamal]

As reported above, the error was in the configuration of JSON parser. Using lenient parsing, this can be ignored. Another workaround is to not add hard line breaks in the JSON itself but it is rudimentary to enforce such restrictions
