Android connection to Remote mysql database JDBC Vs JSON - android

I know that the JDBC is best used with a low latency high-bandwidth connection. and it is better to use a php service.
Thing is am developing a Restaurant menu app that should retrieve data from a db located on a server. using the Samsung galaxy tab2 7inch as the target device and having a stable wireless connection with high bandwidth.My first attempt was to have a java server running on the same machine that have the db and have alot of threads that will retrieve data and send them to android device over a tcp socket.
This implementation resulted in high cpu usage both on the host machine and the android device since i have a lot of threads working in the background.
I though to give JDBC a try since the environment enable me to use such implementation. but so far not successful with connecting to the DB.even tho i have internet permission on the android application Manifest.
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
Class.forName("com.mysql.jdbc.Driver");
this.setTitle("Driver started ");
Connection con = (Connection) DriverManager.getConnection("jdbc:mysql://192.168.1.3/cafe", "root", "1234");
this.setTitle("Connected to db");
} catch (ClassNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (SQLException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
this code will give me the following error
04-07 15:22:41.222: W/System.err(11318): com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure

As for the PHP web-service i really dont know anything how to use it or setup it. what do you guys think i should do ? continue with my first implementation or switch to a direct approach from the android device to the mysql db using a php service .
Sorry This is considered a duplicate . i just want your opinion about the problem am having and if someone could point me to a better approach or can help with the error from the JDBC i will be thankful.


Only yesterday did another user ask the same thing and there are some good answers to be found on that question - JDBC vs Web Service for Android
As for the PHP web-service i really dont know anything how to use it or setup it.
I guess you're gonna have to take a 101 on that.

Xamarin.Android collapsing toolbar very laggy

I'm trying to complete the following code lab using Xamarin.Android: https://codelabs.developers.google.com/codelabs/Material-Design-Style/#0
However, the collapsing toolbar is very laggy. When scrolling down I have to wait more than a full second for the app to catch up and show the updated (collapsed) toolbar. CPU usage during this time is 100%. Starting the DetailActivity also takes much longer than normal. The image I'm trying to load is a bit over 3 MB in size.

public class DetailActivity : AppCompatActivity
{
protected override void OnCreate(Bundle savedInstanceState)
{
base.OnCreate(savedInstanceState);
SetContentView(Resource.Layout.activity_detail);
SetSupportActionBar(FindViewById<Toolbar>(Resource.Id.toolbar));
SupportActionBar.SetDisplayHomeAsUpEnabled(true);
CollapsingToolbarLayout collapsingToolbar =
FindViewById<CollapsingToolbarLayout>(Resource.Id.collapsing_toolbar);
collapsingToolbar.Title = GetString(Resource.String.item_title);
}
}
}
I also made this app native in Java using Android Studio and everything runs smooth there.
NOTE: The layout file is exactly the same as the one in the Android Studio project.
Any ideas what the problem could be?
UPDATE: I noticed that the app just crashes on devices with less memory than the ones I tested the app on (out of memory exception). This is the stack trace:

AdMob making my app crash in release version

i just added AdMob to my app. Everything seem to work well when i debug or install release version of app (HTC m7). The problem occurs on CHUWI VX2 device (esky82_tb_cn_kk, Android 4.4). It is very strange because on this device my App works in debug mode but doesn't works in release version. I try turn of pro-gourd but it doesn't help me.
Any one have idea for that?
my manifest
instruction inside my onCreate method:
mAdView = (AdView) findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
mAdView.setAdListener(new AdListener() {
#Override
public void onAdClosed() {
super.onAdClosed();
mAdView.setVisibility(View.GONE);
}
#Override
public void onAdOpened() {
super.onAdOpened();
mAdView.startAnimation(fade_in);
mAdView.setVisibility(View.VISIBLE);
}
#Override
public void onAdFailedToLoad(int errorCode) {
super.onAdFailedToLoad(errorCode);
mAdView.setVisibility(View.GONE);
}
#Override
public void onAdLoaded() {
super.onAdLoaded();
mAdView.startAnimation(fade_in);
mAdView.setVisibility(View.VISIBLE);
}
#Override
public void onAdLeftApplication() {
super.onAdLeftApplication();
mAdView.setVisibility(View.GONE);
}
});
mAdView.loadAd(adRequest);

mAdView.setAdListener(new AdListener() {

what is this ?
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
what were you expecting? to hit both sides?
try this
android:layout_alignParentRight="true"
android:layout_alignParentEnd="true"
and let the rest go

You are getting a NullPointerException on line 450 of Main.
Look at that line. Something there has not been initialised.

I solve my problem. This issue isn't connect with AdView. It was problem with project. I made small mistakes. I don't have this line
<?xml version="1.0" encoding="utf-8"?>
on the start of xml layout file. I don't know how it can event works.
I reboot device
I added missing line to xml
I clean project (Build > Clean Project)
I rebuild project (Build > Rebuild Project)
Then my apk starts work without progourd but crash when I enable this feature. So i find this solution
I configure progourd configuration file like this.

You have an array out of bound in com.prologica.procamera.MainActivity UploadPhotos.SendFolders(MainActivity.java:127). Check line 127 in MainActivity to make sure you are not going out of bounds. According to the log, the length is 5 and you are trying to access index 5(which does not exist)

IBM Worklight - Handling push notifications in a Native Page

I am creating a Worklight-based Hybrid application with the Android environment.
My application has push notifications configured. It is currently able to process incoming notifications and display the message payload in a pop-up box.
I would like to do the same in the native portion of the hybrid app (native pages initiated using WL.NativePage.show).
However, I'm encountering some problems when trying to get the Push object to register the registerEventSourceCallback handler.
What am I doing wrong?
Activity (Native page):
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
WLClient client = WLClient.createInstance(this);
WLPush push = client.getPush(); // throws exception here
push.registerEventSourceCallback("myAndroid", "PushAdapter","PushEventSource", new PushNotificationListener() );
...
}

Possible Solution:-
public class GCMIntentService extends com.worklight.androidgap.push.GCMIntentService {
#Override
protected void onMessage(Context context, Intent intent) {
if (!MyNativePage.isForeground()) {
// custom native page is not in foreground, handle it using existing WL methods
super.onMessage(context, intent);
} else {
// custom native page is in foreground, skip existing WL method and use custom method
MyNativePage.setNotificationMessage(intent.getExtras().getString("payload"));
}
}
}

Worklight contains 2 push implementations. One is for Hybrid apps and another is for Native apps using the Worklight Native API.
The two do not work together. This means that you cannot receive a notification in the Hybrid app >> navigate to a native page using WL.NativePage.show >> and then use the Worklight Native API for push to handle the received payload.
What you can you, is receive the notification in the Hybrid app and pass along its payload as you load the native page.
Passing data from Hybrid to Native is explained and demoed in the following training module:
