  B. JSONObject line;try {while ((line = reader.readJSONObject ()) != null) {builder.append(line);}JSONObject json = new JSONObject(builder.toString());return json;} catch (IOException | JSONException exception) {exception.printStackTrace();}
  C. String line;try {while ((line = reader.readLine()) != null) {builder.append(line);}JSONObject json = new JSONObject(builder.toString());return json;} catch (RuntimeException|ArrayIndexOutOfBoundsException exception) {exception.printStackTrace();}

  A. Yes.
  B. No, if you define new build types that should be debuggable, you must add `debuggable false'
  C. No, the debug variant should be visible in the build.gradle file anyway.
  A. Yes.

  What do you want from Room when you create a DAO method and annotate it with @Update? Example:
