在eclipse中导出Android项目

Question

I want to export my Android project in order to publish on Google Play. It got exported successfully.

look at these lines of code:

GsonSyncPathResolverModel gsonSyncPathResolverModel = new GsonSyncPathResolverModel(new GsonBuilder());
            String TAG = "SyncPathReslover";

            HttpResponse licenceManagementResponse = Client.get(REST_URL.GETSynchURLResolver(customerID));
            int responseCode = licenceManagementResponse.getStatusLine().getStatusCode();
            String responseString = EntityUtils.toString(licenceManagementResponse.getEntity());
            Log.e(TAG, "response " + responseString);
            System.out.println(responseString);
            responseString=responseString.replace("{\"GetOrganizationInformationByOrganizationNumberResult\":\"[{","{");
            responseString=responseString.replace("}]\"}","}");
            responseString=responseString.replace('\\', Character.MIN_VALUE);
            responseString=responseString.replaceAll(""+Character.MIN_VALUE,"");

            System.out.println("#zzz "+responseString);

            if (responseCode == 200) {
                // syncPathResolver
                licenceManagementResponse.getEntity().consumeContent();
                SyncPathResolverModel syncPathResolverModel = gsonSyncPathResolverModel.parseJSON(responseString);

                Log.e(TAG, "Response from Server:  Organization ID:" + syncPathResolverModel.getObjectEntry_ID());
                Log.e(TAG, "Response from Server:  Sync Path:" + syncPathResolverModel.getSyncServiceURL());

When I run the project directly from the eclipse, The last line of code works fine, and print out the proper value.

but when I use the exported .apk file,

Log.e(TAG, "Response from Server:  Organization ID:" + syncPathResolverModel.getObjectEntry_ID());
Log.e(TAG, "Response from Server:  Sync Path:" + syncPathResolverModel.getSyncServiceURL());

These two lines print out null .

Can you help me what is the problem with exporting the .apk file?

It seems that the gson.jar library does not work when I signed the .apk file

Answer 1

The reason that json.jar file did not work properly after export the .apk files was related to enabling ProGuard . So if I disable it or configure it properly, the .jar files will also work properly.

Answer 2

Open the project properties in Eclipse. Select Java Build Path, click the Order and Export tab. Make sure gson.jar is checked for export.
