PhoneGap set-up with Eclipse for Android

1. Install latest version of NodeJs from here - http://nodejs.org/.
2. Update Android ADT with latest one.Eclipse->Help-> Check for updates or install new software.and provide this link and update http://dl-ssl.google.com/android/eclipse/


3. Update Android SDK. Eclipse-> window-> Android SDK Manager.
4. Install PhoneGap. Refer following Link: http://docs.phonegap.com/en/edge/guide_cli_index.md.html#The%20Command-Line%20Interface.
5. Install Cordova and create a new project. Refer following Link :          http://codingsquare.blogspot.in/2013/08/creating-cordova-3-android-project.html.
6. Once project is created Import project to Eclipse. Refer Link: http://docs.phonegap.com/en/edge/guide_platforms_android_index.md.html#Android%20Platform%20Guide.
7. Once you have imported project in eclipse, Error will show in the Hello Project saying "Andrdoid Reference library is missing/ Hello-Cordova-lib.jar is missing ". Then Clean the library project and rebuild it and your are done, that error will go off.

Data sharing between two apps.. Android

Moreover, making any file MODE_WORLD_READABLE or (worse) MODE_WORLD_WRITEABLE is a bad idea. You lose any hope of security.

If you wish to share data between two applications, there are a myriad of solutions, such as:

• service with an API exposed by AIDL
• service with an API exposed via commands sent via startService() and responses sent via aMessenger or createPendingResult() PendingIntent or something
• content provider
• broadcast Intents

All of those allow you to define permissions for integration and let you control the granularity of access.

Add Java Docs Eclipse

To use offline Java API Documentation in Eclipse, you need to download it first. The link for Java docs are (last updated on 2013-10-21):

Java 6
Page: http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u25-doc-download-355137.html
Direct: http://download.oracle.com/otn-pub/java/jdk/6u30-b12/jdk-6u30-apidocs.zip

Java 7
Page: http://www.oracle.com/technetwork/java/javase/documentation/java-se-7-doc-download-435117.html

1. Extract the zip file in your local directory.
2. From ecliplse --> Window --> Preferences --> Java --> "Installed JREs" select available JRE (jre6 C:\Program Files (x86)\Java\jre6 for instance) and click Edit.
3. Select all the "JRE System libraries" using CTRL key.
4. Click "Javadoc Location"
5. Change "Javadoc location path:" from "http://download.oracle.com/javase/6/docs/api/" to "file:/E:/Java/docs/api/".
6. 
   

Alternatively:

To view the standard Java JDK API documentation for all the classes that come with Java open up the tree in the "Package Explorer" for the JRE System Library, select rt.jar (the runtime library)

From the "Navigate" menu select "Open External Javadoc" and you will see the Java API documentation. The default location of the documentation is Sun's website so the URL in the browser will be something like

http://java.sun.com/j2se/1.7.0/docs/api/index.html

To use our own local version of the documentation in

file:/C:/Program Files/Java/jdk1.7.0_04/docs/api/

so that we don't need to connect to the internet each time we want to view the documentation.

To make the change right click on the rt.jar entry in the "Package Explorer" and select "Properties" to get the dialog box

We need to change the URL in the "Javadoc location path". You can either type in the local value directly or use its browse button to navigate to

Click "OK" and you should have the dialog box

showing the local URL

file:/C:/Program Files/Java/jdk1.5.0_04/docs/api/

Click "Apply" and then "OK".

Now to see the API documentation select rt.jar and choose "Open External Javadoc" from the "Navigate" menu (shortcut is Shift F2). Your local URL will now be shown in the browser address bar.

Pending Intent

https://allaudin.github.io/pending-intent/- A good reference

A PendingIntent is a token that you give to another application (e.g. Notification Manager, Alarm Manager or other 3rd party applications), which allows this other application to use the permissions of your application to execute a predefined piece of code.

For Example, if we want to start our Service(which requires some special  permission like gps, action battery change etc), through AlarmManager which will trigger that service some-point in future at regular interval.
Then we create a pending intent for our service and we give this intent to other application viz. in this case is AlarmManager Now AlarmManager will use the permission(gps, vibrate, etc) of our service to execute code.

Intent intent = new Intent(this, MyService.class);
    PendingIntent pendingIntent = PendingIntent.getBroadcast(this.getApplicationContext(), 234324243, intent, 0);
    AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
    alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()
        + (i * 1000), pendingIntent);

If you give the foreign application an Intent, and that application sends/broadcasts the Intent you gave, they will execute the Intent with their own permissions. But if you instead give the foreign application a PendingIntent you created using your own permission, that application will execute the contained Intent using your application's permission.
A PendingIntent has defined Activity, Broadcast or Service  within it, and those can be sent to other applications to use it.
I can define my Intent (Activity, BroadcastReceiver or Service) and can send to other application to use it. 

Why PendingIntent is required ?

If I create Intent,
Intent bIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);

and sending "bIntent" to other application , which is not having permission (android.permission.BLUETOOTH_ADMIN).

So, When I do, 
startActivity(bIntent);

It will never launch bluetooth enabling Activity.

If we use PendingIntent, the application (which use PendingIntent) no need to have permission. But the application which creates PendingIntent must have required permission for Intents.

PendingIntent can be created using it's static methods getActivity(), getBroadcast() and getService().

Let's see sample for PendingIntent,

public class IParcel implements Parcelable

{

    PendingIntent pIntent = null;

   

    public IParcel(PendingIntent pi)

    {

        pIntent = pi;

    }

   

    public IParcel(Parcel in)

    {

        pIntent = (PendingIntent)in.readValue(null);

    }

   

    public static Parcelable.Creator<IParcel> CREATOR = new Parcelable.Creator<IParcel>(){

        @Override

        public IParcel createFromParcel(Parcel source) {

            // TODO Auto-generated method stub

            return new IParcel(source);

        }

        @Override

        public IParcel[] newArray(int size) {

            // TODO Auto-generated method stub

            return null;

        }

       

    };

  

    @Override

    public int describeContents() {

        // TODO Auto-generated method stub

        return 0;

    }

    @Override

    public void writeToParcel(Parcel dest, int flags) {

        // TODO Auto-generated method stub

        dest.writeValue(pIntent);

       

    }

   

}

public class FirstApp extends Activity {

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        // TODO Auto-generated method stub

        super.onCreate(savedInstanceState);

    

        Intent myIntent = new Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE);

        PendingIntent pIntent = PendingIntent.getActivity(this, 0, myIntent,PendingIntent.FLAG_ONE_SHOT);//FLAG_ONE_SHOT - only once pIntent can use the myIntent

     

        IParcel ip = new IParcel(pIntent);

    

        Intent sndApp = new Intent();

        sndApp.setComponent(new ComponentName("com.myapp", "com.myapp.SecondApp"));

        sndApp.putExtra("obj",ip);

        startActivity(sndApp);

        }

}

public class SecondApp extends Activity {

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        // TODO Auto-generated method stub

        super.onCreate(savedInstanceState);

       IParcel pc = getIntent().getExtras().getParcelable("obj");

       if(pc != null){

               pc.pIntent.send(); // this will launch the bluetooth enabling activity

       } 

       }

}
