List<SkuDetails> to json gives incomplete json list

I receive a List<SkuDetails> as following:

public void onSkuDetailsResponse(BillingResult billingResult,
                                List<SkuDetails> skuDetailsList) {
    Gson gson = new Gson();
    String json = gson.toJson(skuDetailsList);
    Log.d(TAG, json);

SkuDetails doc

Then I get this unfinished json:

[{"zza":"{\"skuDetailsToken\":\"s-r3R-r\",\"productId\":\"chill_lo_fi\",\"type\":\"inapp\",\"price\":\"R$ 5,49\",\"price_amount_micros\":5490000,\"price_currency_code\":\"BRL\",\"title\":\"Chill Lo-Fi (SDoubleKick - Footdrum - SS)\",\"description\":\"Chill Lo-Fi sound pack\"}","zzb":{"nameValuePairs":{"skuDetailsToken":"s-r3R-r","productId":"chill_lo_fi","type":"inapp","price":"R$ 5,49","price_amount_micros":5490000,"price_currency_code":"BRL","title":"Chill Lo-Fi (SDoubleKick - Footdrum - SS)","description":"Chill Lo-Fi sound pack"}}},{"zza":"{\"skuDetailsToken\":\"a-r\",\"productId\":\"percussion_and_fx\",\"type\":\"inapp\",\"price\":\"R$ 5,49\",\"price_amount_micros\":5490000,\"price_currency_code\":\"BRL\",\"title\":\"Percussion and Fx (SDoubleKick - Footdrum - SS)\",\"description\":\"Percussion and Fx sound pack\"}","zzb":{"nameValuePairs":{"skuDetailsToken":"s-dsf3

You can see that this is a list, it should have printed correctly, but I get, in the end:

"zzb":{"nameValuePairs":{"skuDetailsToken":"s-dsf3

Because of that, when I reconstruct this gson into an object, I get an exception

Gson will not truncate your JSON data. logcat is the culprit here, by default, it will truncate any log message that it considers to be too long. This can happen both inside of your IDE and when running logcat on the command line. To get rid of the log capping you can split the string you want to log with creating a wrapper something like this:

package com.github.fundamentals.array;

public class Log {

  public static void d(String tag, String jsonText) {
    int maxLogSize = 2000;
    for (int i = 0; i <= jsonText.length() / maxLogSize; i++) {
      int start = i * maxLogSize;
      int end = (i + 1) * maxLogSize;
      end = end > jsonText.length() ? jsonText.length() : end;
      android.util.Log.d(tag, jsonText.substring(start, end));
    }
  }

}

You can also use setPrettyPrinting on GsonBuilder to print a JSON string in a human-readable format (for debugging)

Gson gson = new GsonBuilder().setPrettyPrinting().create();
String prettyJson = gson.toJson(json);
Log.d(TAG, prettyJson);
