Android App- PC CONNECT

APP SCREENSHOTS

This app has been designed to allow users to control their PC/Laptops using their Mobile Phones.
It allows following functionalities:

1. CONTROL PC using MOBILE PHONE

It allows users to create a virtual Mouse that allows users to move their fingers on Mobile phone while the mouse pointer on the PC moves. This will allow users to control their PC even if they are a few meters away as like when to deliver a presentation etc. The app also allows users to Play/Pause music of their choice on PC and control the songs like next, previous ,mute etc from the app itself.
Think if you are playing songs on Laptop and it is placed on table away from your bed, then you can control it without moving from your bed.


2. MOBILE To PC Transfer

This app allows users to transfer any file(JPEG/PDF/WORD/CONTACT etc) from their mobile phone to PC instantly without any Bluetooth connection or any use of Data Cable. The user needs to have a small software(Link below) and just select a file to be transferred and it will be available in few milliseconds.

3. PC to MOBILE Transfer

Users can also transfer files from their PC to Phone instantly. The file transferred will be available in a folder named PC CONTROL in the External Storage of the phone which can be seen in the File Manager app.

CONCEPTS USED:

The PC CONTROL APP has been created on Android Studio 2.2.1. It uses concepts of Socket Programming. The software for PC have been created using JAVA and Python and have been converted into .exe Applications. It is based on the fact that the PC and Mobile Phone should be connected to same WiFi or the PC should be connected to the Hotspot of the Phone. Having done so, rest all is handled by the app and software as well. The source code of the app and software is Open Source on the following Github Repository. Any updates/modifications to it are most welcome.

Android Networking Library- Android Networking Library

One Line Library is a power android networking library. This
library can be imported in any android existing project using
following
With an aim to minimize developer hardwork this library will help
them to focus on their UI rather then handling network error
themselves.
At present library supports the following:
1. VolleyWithOKHTTP Request
2. ImageUpload
3. Download Image
4. Post Request
5. Get Request
6. Cancel / Abort Request
7. JSON Object Request
8. Network Health Status

 Download and use the library now:

 Maven:
        <dependency>
        <groupId>onelinelibrary.com.onelinelibrary</groupId>
        <artifactId>onelinelibrary</artifactId>
        <version>1.0.0</version>
        <type>pom</type>
        </dependency>

 Gradle:

compile 'onelinelibrary.com.onelinelibrary:onelinelibrary:1.0.0'

Tutorial :

• VolleywithOKHTTP:

As we know volley by Google is well known for its network cancel feature and OKHTTP for its speed and performance. We tried to integrate both into one function by modifying the Volley function to use OKHTTP Response.

StringRequest stringRequest = new StringRequest("http://resolvefinance.co.uk/Whatsapp/json3.txt",

new Response.Listener<String>() {

@Override

public void onResponse(String response) {

Log.i("Response returned is","-"+response);

try{

parseJSON(response);

}

catch (Exception e){

Toast.makeText(c1,"Please check your Internet

Connection",Toast.LENGTH_LONG).show();

}

}
},

new Response.ErrorListener() {

@Override

public void onErrorResponse(VolleyError error) {

// Toast.makeText(MainActivity.this,

error.getMessage(), Toast.LENGTH_LONG).show();

Log.i("Volley ka error", "" + error);

}

});

RequestQueue requestQueue = Volley.newRequestQueue(c1, new OkHttpStack(new

com.squareup.okhttp.OkHttpClient()));

requestQueue.add(stringRequest);

• Getting response from API() 

Getting reponse from API is now very simple. Just add the URL of the API to the load parameter and pass all the query parameters as key value pairs, the response could be parsed as String, JSON object ,JSON Array, Bitmap etc.

OneLineLibrary.load("http://jiittute.esy.es/getContents.php")
.setTag("LoadingAPI")

.addQueryParameter("userid","1")
.setPriority(Priority.LOW)
.start()
.getAsString(new StringRequestListener () {
@Override
public void onResponse(String response) {
Log.d(TAG, "onResponse API"+response);
}
@Override
public void onError(ANError error) {
Log.d(TAG, "ERROR aPI");
}
});

• ImageUpload() 

Use this to upload image from your internal storage of your phone. For instance suppose you have an image name screens.png located at following path

―Environment.getExternalStorageDirectory().getPath()+"/MAJOR/screens.jpg"

We can push the following file directly to servers by writing the following one Line function.

 File file=new
File(Environment.getExternalStorageDirectory().getPath()+"/MAJOR/screens.jpg");
OneLineLibrary.upload("http://jiittute.esy.es/MAJOR/postFile.php")
.parameter("pic",file)
.setTag("uploadTest")
.start()
.getAsJSONObject(new JSONObjectRequestListener() {
@Override
public void onResponse(JSONObject response) {
// do anything with response
Log.d("MAJOR","IMAGE_REQUEST MADE"+response.toString());
}
@Override
public void onError(ANError error) {
// handle error
Log.d("MAJOR","IMAGE_REQUEST MADE"+error.getMessage());
}
});

• LoadImageDirectly()-

Use this to download image as a Bitmap response from the network.

 OneLineLibrary.load("http://jiittute.esy.es/MAJOR/uploads/screens.jpg")
.setTag("imageRequestTag")
.setPriority(Priority.LOW)
.setBitmapConfig(Bitmap.Config.ARGB_8888)
.start()
.getAsBitmap(new BitmapRequestListener() {
@Override
public void onResponse(Bitmap response) {
Log.d(TAG, "onResponse Bitmap");
}
@Override
public void onError(ANError error) {
Log.d(TAG, "ERROR Bitmap");
}
});

• Cancel/Abort Network Request

OneLineLibrary.cancelAll();

Network Health Status - Calling this function will return you the network heath

status. In background it downloads the 1MB file from the remote servers and calculate

time. Based on this it calculate bandwidth of the network that ie. Bits transferred per

second.

Additional Features

1. ―Priority TYPES : User can choose from the multiple request time which

includes LOW, MEDIUM, HIGH and IMMEDIATE.

2. TAG name: You can assign Tag with your network call and can later cancel it

using.

3. ProgressListner: Some of the modules include progress listeners by

calculating received bytes and send bytes;

cancelRequestWithGivenTag(tagname);
