I've recently upgraded the android app I'm working on from an old unsupported version of CBL Android to version 1.0.1.
Before utf-8 encoding:
uSMo@W?=4JG"BġV8c{ٝMuM$>X|y/.gq*J -;g2ú7Ӽ~dSJoa`uO0vlJ1Dr27_

After utf-8 encoding: %1F%EF%BF%BD%08%00%00%00%00%00%00%03uSMo%EF%BF%BD%40%10%EF%BF%BDW%EF%BF%BD%3F%0C%3D4%12J%13%EF%BF%BDG%1A%22%EF%BF%BDB%C4%A1%EF%BF%BD%EF%BF%BDV%EF%BF%BD8%EF%BF%BD%EF%BF%BDc%7B%EF%BF%BD%EF%BF%BD%D9%9DM%EF%BF%BD%10%EF%BF%BD etc etc..
Relevant code is below:
/**

}
}

}
};
if (android.os.Build.VERSION.SDK_INT <= android.os.Build.VERSION_CODES.HONEYCOMB) {
task.execute();
} else {
task.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR);
}
}
/**

}

}
/**

*/

InputStream ret = null;
if (id == null || attachmentId == null) {
return null;
} else {
Database structuralDB;
try {
structuralDB = SevenCityApplication.getDatabase(dbName);
Document doc = structuralDB.getDocument(id);
Revision rev = doc.getCurrentRevision();
Attachment att = rev.getAttachment(attachmentId);
if(att != null) {
ret = att.getContent();
}
} catch (CouchbaseLiteException e) {
e.printStackTrace();
}
return ret;
}
}
The attachment content type is text/html. The thnl rendered fine with the old CBL/Ektorp setup.
Do I have to process the InputStream in method inputStreamAsString differently with CBL 1.0.x?
