java.lang.NoClassDefFoundError on Android devices with KitKat

Question

I am developing a app and at the moment the app crashes if I use Android KitKat but with Lollipop devices the app runs without crash. The error from LogCat:

java.lang.NoClassDefFoundError: mypackage.utils.PlacesAutoCompleteAdapter$1
at mypackage.utils.PlacesAutoCompleteAdapter.getFilter(PlacesAutoCompleteAdapter.java:60)

The class is inside the package of the error:

package mypackage.utils;

public class PlacesAutoCompleteAdapter extends ArrayAdapter<String> implements Filterable {

    private static final String TAG = "AutoCompleteAdapter";

    // Autocomplete Google Places
    private static final String PLACES_API_BASE = "https://maps.googleapis.com/maps/api/place";

                if (constraint != null) {
                    // Retrieve the autocomplete results.
                    resultList = autocomplete(constraint.toString());

                    // Assign the data to the FilterResults
                    filterResults.values = resultList;
                    filterResults.count = resultList.size();
                }
                return filterResults;
            }

            @Override
            protected void publishResults(CharSequence constraint, Filter.FilterResults results) {
                if (results != null && results.count > 0) {
                    notifyDataSetChanged();
                } else {
                    notifyDataSetInvalidated();
                }
            }
        };
        return filter;
    }

    /**
     * Autocomplete text input with Google places
     *
     * @param input: Text input from AutoCompleteTextView
     * @return ArrayList<String>
     */
    private ArrayList<String> autocomplete(String input) {
        ArrayList<String> resultList = null;

        HttpURLConnection conn = null;
        StringBuilder jsonResults = new StringBuilder();
        try {
            StringBuilder sb = new StringBuilder(PLACES_API_BASE + TYPE_AUTOCOMPLETE + OUT_JSON);

            sb.append("&components;=country:de");
            sb.append("&input=" + URLEncoder.encode(input, "utf8"));

            URL url = new URL(sb.toString());
            conn = (HttpURLConnection) url.openConnection();
            InputStreamReader in = new InputStreamReader(conn.getInputStream());

            // Load the results into a StringBuilder
            int read;
            char[] buff = new char[1024];
            while ((read = in.read(buff)) != -1) {
                jsonResults.append(buff, 0, read);
            }
        } catch (MalformedURLException e) {
            Log.e(TAG, "Error processing Places API URL", e);
            return null;
        } catch (IOException e) {
            Log.e(TAG, "Error connecting to Places API", e);
            return null;
        } finally {
            if (conn != null) {
                conn.disconnect();
            }
        }

        try {
            // Create a JSON object hierarchy from the results
            JSONObject jsonObj = new JSONObject(jsonResults.toString());
            JSONArray predsJsonArray = jsonObj.getJSONArray("predictions");

            // Extract the Place descriptions from the results
            resultList = new ArrayList<String>(predsJsonArray.length());
            for (int i = 0; i < predsJsonArray.length(); i++) {
                resultList.add(predsJsonArray.getJSONObject(i).getString("description"));
            }
        } catch (JSONException e) {
            Log.e(TAG, "Cannot process JSON results", e);
        }

        return resultList;
    }
}

So again the app runs without crash using Android Lollipop, anyone an idea why it crashes on KitKat? My minSDKversion is 16, the targetSDKversion 21

This can be happen if your application class is not instantiating double check your Menifest.xml for application class entry . And Your application class should look like:

public class AppController extends MultiDexApplication {
public void onCreate() {
    super.onCreate();

}

@Override
protected void attachBaseContext(Context base) {
    super.attachBaseContext(base);
    MultiDex.install(this);
}

}

add dependency compile 'com.android.support:multidex:1.0.1'
add multiDexEnabled = true option to your build.gradle under default config:

defaultConfig {

    applicationId "com.app"
    minSdkVersion 19
    targetSdkVersion 22
    versionCode 1
    versionName "1"
    multiDexEnabled = true

}

Thats it.

I have observed this error in two situations previously:

1. I was using a physical device (i.e. not an emulator) that had Kitkat with ART enabled. When I ran the app on another Kitkat device with Dalvik runtime, the error seemed to have vanished.

2. The same problem arose due to a .dex build error which occurred when I shifted the SVN to another location. I deleted the old project entirely and created a new repository from the original project on my computer, and after rebuilding the project entirely the error did not reappear.

Thanks for your hints, I resolved the problem by changing `multiDexEnabled = true` to `multiDexEnabled = false` in my build.gradle – Mokkapps Mar 08 '15 at 17:39
