Cordova Exec blocked the main thread even after usage of CordovaInterface.getThreadPool()

android, cordova

Solution

According to THREAD WARNING: exec() call blocked the main thread. Plugin should use CordovaInterface.getThreadPool(). – Cordova Plugin Warning, try the following:

    public boolean execute(String action, final JSONArray inputs, final CallbackContext callbackContext) throws JSONException {
        if (action.equals("setAndroidPreferences")) {
            cordova.getThreadPool().execute(new Runnable() {
                @Override
                public void run() {
                    callbackContext.sendPluginResult(setAndroidPreferences(inputs));
                }
            });
        }
    }

    private PluginResult setAndroidPreferences(JSONArray args) {
        try {
            if ( /* ... */) {
                SharedPreferences settings = cordova.getActivity().getSharedPreferences(preferenceLib, Context.MODE_PRIVATE);
                SharedPreferences.Editor editor = settings.edit();

                editor.putString(preferenceName, preferenceValue);
                editor.commit();
                return new PluginResult(PluginResult.Status.OK);                     
            } else {
                return new PluginResult(PluginResult.Status.ERROR);
            }
        } catch (JSONException e) {
            e.printStackTrace();
            Log.e(TAG, "getSetSharePreferences" + ": Error: " + PluginResult.Status.JSON_EXCEPTION);
            return new PluginResult(PluginResult.Status.JSON_EXCEPTION);
        }
    }
}
