Android pushNotification badge ICON similar to IOS

1.    Create a appwidget-provider xml name it as widget_badge_icon.xml and add it in xml folder

2.    Create a widget_badge_layout .xml as per need.

3.    Create a receiver in manifest file.

4.    Create BadgeNotificationWidget Class:

package com.example.testwidget;

import java.util.Timer;

import java.util.TimerTask;

import android.app.IntentService;
import android.appwidget.AppWidgetManager;
import android.content.ComponentName;

import android.view.View;
import android.widget.RemoteViews;

/**
 * BadgeService is a worker thread used to send the badge number as a broadcast
 * message to change the app icon.
 *
 *
 */
public class BadgeService extends IntentService {

    int count = 0;

    Timer timer;

    int randomNo = 10;

    public BadgeService() {
        super("BadgeService");
        timer = new Timer();
    }

    /**
     * This method is invoked on the worker thread with a request to process.
     */
    @Override
    protected void onHandleIntent(final Intent intent) {

        RemoteViews remoteView = new RemoteViews(getApplicationContext()
                .getPackageName(), R.layout.widget_badge_layout);

        ComponentName componentName = new ComponentName(
                getApplicationContext(), BadgeNotificationWidgetActivity.class);

        AppWidgetManager appWidgetManager = AppWidgetManager
                .getInstance(getApplicationContext());

        Log.d("BadgeNotificationWidgetActivity", "BadgeService randomNo"
                + randomNo);
        if (randomNo == 0) {
            remoteView.setViewVisibility(R.id.badgeNum, View.GONE);
        } else {
            remoteView.setViewVisibility(R.id.badgeNum, View.VISIBLE);
        }

        remoteView.setTextViewText(R.id.badgeNum, String.valueOf(randomNo));
        // apply changes to widget
        appWidgetManager.updateAppWidget(componentName, remoteView);

    }

Then type lint --html --sample pathoftheproject

HTML report gets generated in the sdk--->tools with the name --sample



TreeMap is an example of a SortedMap, which means that the order of the keys can be sorted, and when iterating over the keys, you can expect that they will be in order.

HashMap on the other hand, makes no such guarantee. Therefore, when iterating over the keys of a HashMap, you can't be sure what order they will be in.

HashMap will be more efficient in general, so use it whenever you don't care about the order of the keys.


Daemon thread in Java are those thread which runs in background and mostly created by JVM for performing background task like Garbage collection and other house keeping tasks. Difference between Daemon and Non Daemon(User Threads)  is also an interesting multi-threading interview question, which asked mostly on fresher level java interviews. In one line main difference between daemon thread and user thread is that as soon as all user thread finish execution java program or JVM terminates itself, JVM doesn't wait for daemon thread to finish there execution. As soon as last non daemon thread finished JVM terminates no matter how many Daemon thread exists or running inside JVM.

 1) JVM doesn't wait for any daemon thread to finish before existing.

2) Daemon Thread are treated differently than User Thread when JVM terminates, finally blocks are not called, Stacks are not unwounded and JVM just exits.

Push Notifications

Introduction

Sample App which registers with GCM and receives device token from it 

GCM Service Class

import android.app.Notification;

import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

import com.google.android.gcm.GCMBaseIntentService;

public class GCMIntentService extends GCMBaseIntentService {

    private static String TAG = GCMIntentService.class.getName();
    /**
     * Intent used to display a message in the screen.
     */
    public static final String DISPLAY_MESSAGE_ACTION = "com.google.android.gcm.demo.app.DISPLAY_MESSAGE";

    /**
     * Intent's extra that contains the message to be displayed.
     */
    public static final String EXTRA_MESSAGE = "message";

    public GCMIntentService() {
        super("project no");
    }

    @Override
    protected void onError(Context context, String errorId) {
        Log.i(TAG, "Received message " + errorId);
    }

    @Override
    protected void onMessage(Context context, Intent intent) {
        Log.i(TAG, "Received message");
        // String message = getString(R.string.gcm_message);
        String message = intent.getExtras().getString("message");
        displayMessage(context, message);
        // notifies user
        generateNotification(context, message);
    }

    @Override
    protected void onRegistered(Context context, String registrationId) {
        Log.i(TAG, "Device registered: regId = " + registrationId);
    }

    @Override
    protected void onUnregistered(Context context, String registrationId) {
        // TODO Auto-generated method stub

    }

    private void displayMessage(Context context, String message) {
        Intent intent = new Intent(DISPLAY_MESSAGE_ACTION);
        intent.putExtra(EXTRA_MESSAGE, message);
        context.sendBroadcast(intent);
    }

    /**
     * Issues a notification to inform the user that server has sent a message.
     */
    private static void generateNotification(Context context, String message) {

        int icon = R.drawable.ic_launcher;
        long when = System.currentTimeMillis();
        NotificationManager notificationManager = (NotificationManager)context.getSystemService(Context.NOTIFICATION_SERVICE);
        Notification notification = new Notification(icon, message, when);
        String title = context.getString(R.string.app_name);
        Intent notificationIntent = new Intent(context, TimerScreen.class);
        // set intent so it does not start a new activity
        notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
        PendingIntent intent =PendingIntent.getActivity(context, 0, notificationIntent, 0);
        notification.setLatestEventInfo(context, title, message, intent);
        notification.flags |= Notification.FLAG_AUTO_CANCEL;
        notificationManager.notify(0, notification);

    }
}

BroadCast Receiver

package com.example.responsetest;

import android.app.Activity;

import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;

public class TimerScreen extends Activity {
    /**
     * Intent's extra that contains the message to be displayed.
     */
    public static final String EXTRA_MESSAGE = "message";

    private final BroadcastReceiver mHandleMessageReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            String newMessage = intent.getExtras().getString(EXTRA_MESSAGE);
        }
    };

}

MainActivity

package com.example.responsetest;

import com.google.android.gcm.GCMRegistrar;


import android.os.Bundle;
import android.app.Activity;
import android.util.Log;
import android.view.Menu;

public class MainActivity extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
       
        // Make sure the device has the proper dependencies.
                GCMRegistrar.checkDevice(this);

                // Automatically registers application on startup.
                GCMRegistrar.register(this, "projectno");

                final String regId = GCMRegistrar.getRegistrationId(this);
                Log.d("GCMIntentService", "GCMIntentService " + regId);
               
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}

Client Jar

GCM Client jar is needed

java handling string and splitting it in key-value

public class StringSplit {

            public static void main(String[] args) {

                        String assetClasses = "name = Gold: price = Stocks:icome = Fixed :********";

                        assetClasses.replace("*", "");

                        String[] splits = assetClasses.split(":");

                        HashMap<String, String> hash = new HashMap<String, String>();

                        System.out.println("splits.size: " + splits.length);

                        for (String asset : splits) {

                                    if (asset.indexOf("=") != -1) {

                                                String[] splitstwo = asset.split("=");

                                                //if ((splitstwo.length == 2))

                                                            hash.put(splitstwo[0], splitstwo[1]);

                                                for (String splitasset : splitstwo) {

                                                            System.out.println(splitasset);

                                                }

                                    }

                                    System.out.println(asset);

                                    System.out.println(hash);

                        }

            }

}

Calling other App from one App

package com.example.testintaller;

import android.app.Activity;

import android.content.Intent;
import android.content.pm.PackageManager;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;

public class MainActivity extends Activity {

    private Button btn;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        btn = (Button) findViewById(R.id.button1);

        btn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub

               

                   
                     Intent intent = new Intent(Intent.ACTION_MAIN);
                     intent.setClassName("package", "package.classname");
                     intent.putExtra("name", "xxx");
                     intent.putExtra("password", "yyyy");
                    startActivity(intent);
                   
           

            }
        });

    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        // Inflate the menu; this adds items to the action bar if it is present.
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

}


Note : Activity class of ther App which you are calling should be exported i,e in manifest we should give as android:exported = "true"

display metrics android(device width zero initially)

Plz add the following to the application oncreate method to get width and height of device




        ((WindowManager) context.getSystemService(Context.WINDOW_SERVICE))
          .getDefaultDisplay().getMetrics(displayMetrics);


DisplayMetrics met =  new DisplayMetrics();
        getWindowManager().getDefaultDisplay().getMetrics(met);
        System.out.println("here  "+met.widthPixels);
        System.out.println("here height is "+met.heightPixels);

Transperency in android canvas

Paint Paint = new Paint();
    Paint.setColor(Color.argb(50, 128, 24, 24));
    Paint.setStyle(Style.FILL);   
    Paint.setAntiAlias(true);


50 is the alpha parameter based on which transperency parameter will vary

Complete excel to strings.xml and localised.txt is stored in google site(includes arrays also)

Java while running some external library file is missing

Do the following

Go to Project->Properties->Java Build Path than select Order and export tab. Set android-support-v4.jar library checked and up it into top of the list. And clean and rebuild..It works for most of the cases


External library is android-support-v4.jar in this case
