[TUT]Server-Client-Socket-Programming-C# - C++ or Other Android Development Languages

Hello everyone, socket programming was the thing I was stuck before. But lately I decided to make a one in my own. So finally I comprehended how it works. So this is a little one which was testing.
----------
Server- I use a console in this.
----------
Code:
Using System.Net.Sockets;
Using System.IO;
Using System.Timers;
Code:
Static TcpListner server = new TcpListener(8888);
Static TcpClient client;
Static Timer t1;
WRITE THIS IN MAIN
Code:
t1 = new Timers();
t1.Enabled = true;
t1.Elapsed+= t1_Elapsed;
t1.interval = 100;
t1.Start();
server.Start();
While (true)
{
client.AcceptTcpClient();
Console.WriteLine("Client Connected");
}
Code:
Static void t1_Elapsed(object sender, ElapsedEventArgs e)
{
Reader();
}
Private static void Reader()
{
try{
StreamReader reader = new StreamReader(client.GetStream());
Console.WriteLine(reader.ReadLine());
}
catch(Exception ex)
{
}
}
-------------
Client-----
-------------
Code:
Using System.Net.Sockets;
Using System.IO;
TcpClient client = new TcpClient();
StreamWriter writer;
Code:
public void Connect()
{
client.Connect("127.0.0.1", 8888);
}
public void SendSomeMsg(String msg)
{
writer = new StreamWriter(client.GetStream());
writer.WriteLine(msg);
writer.Flush();
}
Well, I wrote using my memory, there maybe few mistakes. Btw you can use threading.
Feel free to be creative.
PS:- Can Used With Mono-Droid.

Android - SurfaceView flickers and sometimes does not apply the proper paint

I have been experiencing this issue for quite a while and even after googling a while, I havent found a reasonable solution for my problem.
The issue I am experiencing is that the SurfaceView I am using flickers. Once in a while, the objects I draw flicker and they change their size or colour.
It looks like that sometimes the application skips my calls to 'Paint.setColor()' and the one to 'Paint.setStrokeWidth()'.
I have made methods which change the used paint and then, in order to try to fix this issue, to set it back to the default paint values. Still the issue persists. I have also read that the problem might be due to the double buffering. Is it the case? I am using this code for the DrawingThread:
PS. u can notice that I also tried to use a dirty Rectangle to try to see if the issue can be fixed, but still nothing. [I might not have understood what it actually does.
Code:
class DrawingThread extends Thread {
private SurfaceHolder _surfaceHolder;
private CustomView _cv;
private boolean _run = false;
public DrawingThread(SurfaceHolder surfaceHolder, CustomView cv) {
super();
_surfaceHolder = surfaceHolder;
_cv = cv;
}
public void setRunning(boolean run) {
_run = run;
}
public boolean isRunning() {
return _run;
}
public SurfaceHolder getSurfaceHolder() {
return _surfaceHolder;
}
@Override
public void run() {
Canvas c;
while (_run) {
c = null;
try {
//c = _surfaceHolder.lockCanvas(new Rect(lon - range, lon + range, lat - range, lat + range));
c = _surfaceHolder.lockCanvas();
synchronized (_surfaceHolder) {
_cv.onDraw(c);
}
} finally {
if (c != null) {
_surfaceHolder.unlockCanvasAndPost(c);
}
}
}
}
}
PS. I have read somewhere I should draw on a single bitmap and then draw the bitmap on the canvas. I have tried several times but I cannot manage to do so.
Thanks in advance,
N.
Is there anyone who can help me?
Could someone give me a hand?
I cannot find the reason why I cannot fix this issue.
I have tried to draw the items on a bitmap first and then adding it to the canvas, but I didnt manage and I either get a white canvas or a completely black one.
I believe the issue is quite easy to solve after you do it once.
Not even someone who could give some suggestions?
Hey!
As far as I can see the code you posted looks fine. Can you please post the code of your CustomView class? I think there could be an issue there.
Are you trying to make a game?
Hello!!!!
Finally someone
Here is the code I use for the onDraw(canvas):
Code:
@Override
public void onDraw(Canvas canvas) {
try {
canvas.drawColor(Color.WHITE);
pt.setAntiAlias(true);
canvas.rotate(-90, 0, 0);
canvas.translate(translateX, translateY);
canvas.scale(scale, scale);
canvas.rotate(-rotation, lat, lon);
// Drawing Points
Renderer.drawStreet(gaia.getStreets(), scale, canvas, pt);
Renderer.drawPolygon(gaia.getPolygons(), canvas, pt);
Renderer.drawPOI(myContext, gaia.getPOIs(), canvas, pt, scale, rotation);
Renderer.drawCustomPOI(myContext, gaia.getCustomPOI(), canvas, pt, scale, rotation);
if (showLocation) {
drawMarker(canvas);
}
if(drivingMode)
{
Renderer.drawRoute(gaia.getRoute(), canvas, pt);
}
} catch (Exception e) {
e.printStackTrace();
}
}
This is actually a map renderer.
I know the issue is very likely to be due to the double buffering, but I cannot find a way to fix it.
Thanks!
N.
Can you please post the code for the callback methods (onSurfaceCreated, onSurfaceChanged, onSurfaceDestroyed) and maybe the constructor for the view too? I think the problem could be due to the setting up and not the actual rendering.
How are you accessing the surfaceHolder. Are you using the getHolder() method for that? And are you sending the reference you get to the surfaceHolder from getHolder() to the DrawingThread?
Here is the light version of the code:

Hello,
have you had the chance to check it out?
Thanks
N.
Sorry about that. I did not have access to the internet for the last 2 - 3 days.
Anyways I went through your code...If that is what you call light I wouldn't want to know whats heavy
I noticed that you have two threads which are responsible for drawing to the same view. You are using the DrawingThread to call the onDraw method of your CustomMapView object and the RenderingThread to post the invalidate method of the same CustomMapView object, which also results in a call to the onDraw method of the same view.
I am not really sure if doing this is a good thing and maybe this is what is causing the problems with the rendering? As a test, you could comment out one of the Thread.start() calls to one of the two rendering threads in your onSurfaceCreated method and check if it stops flickering.
I know this isn't how you want your app to function but if it fixes the flickering you'd know its the the two drawing threads that are causing the problem.
Code:
@Override
public void surfaceCreated(SurfaceHolder holder) {
// Comment out either one of the following two if blocks
if (!_thread.isRunning()) {
_thread.setRunning(true);
_thread.start();
}
if (!_threadStreets.isRunning()) {
_threadStreets.setRunning(true);
_threadStreets.start();
}
}
Awesome dude!
It fixed it straight away.
The reason is that I got a thread first and then added a new one, without thinking about just merging them both together
Thanks again!
Yep. You're welcome!
You'll just have to redesign your code to use just one rendering thread and it should work fine. All the best!

Help for Avin App or Auxiliary in

I have a problem that my monkeyboard Dab receiver needs audio in. This can be switched with the avin app. But I only need the Audio switched not the video. Is it possible to make a Task with Tasker or similar to run some code or script to switch the audio.
Because also after boot the avin app is blocking the system. For example pppwidget starts only after exiting the avin app.
I also did take a look at the code of the app but I am a completely noob at java app programming and could not identify the code for switching the audio.
Can anyone understand and help me please?
Thanks

Maybe simple shell command or something? Anyone?
I did a simple Tweak in the Avin app. Now it launches without Ui. For audio in only and only for kitkat roms.
I have a typo in the attached APK...
Hey there, sorry to disturb the old thread I need avin.apk only to show video input, and not cut audio in background for Spotify. Do you think I have a chance?
I suppose It is the direct oppossite of yours.

2nd - if you're still around - can you recompile with this ?
Might be as simple as commenting out the this.am.setParameters calls
Sorry, this is not possible for me. I did not figure it out how to disable the video.

System App reverse enginnering

Hello there!
I would need some help reverse engineering an app and recompiling it with some different code afterwards.
The App coordinates all the different components of my phone to work properly.
When you press the two fingerprint sensors, the app gives you haptic feedback and turns the screen from front to back or vice versa, depending on which side is facing up.
I need the app to do exactly that once when i wake up my phone either with fingerprint or power button, so the display illuminates which is facing up, and not the one i used recently.
I have some experience with java, but all i got are the .smali documents.
Is there any way to reliably get smali into java and back?

Sorry for my bad english!
Thanks!

Hello there!
I would need some help reverse engineering an app and recompiling it with some different code afterwards.
The App coordinates all the different components of my phone to work properly.
When you press the two fingerprint sensors, the app gives you haptic feedback and turns the screen from front to back or vice versa, depending on which side is facing up.
I need the app to do exactly that once when i wake up my phone either with fingerprint or power button, so the display illuminates which is facing up, and not the one i used recently.
I have some experience with java, but all i got are the .smali documents.
Is there any way to reliably get smali into java and back?
Code:
Sorry for my bad english!
Thanks!
Click to expand...
Click to collapse
Try APKtool, open source, most used out there.
"apktool d (nameof the app).apk"
"apktool b (name of the app).apk" to recompile
If it's a system file, make sure you don't modify the original signature by adding -c to the last command.
Have a good day

How to integrate Search Kit?

Article Introduction
In this article we will work in integrate search and will explore many features together in this service.
Search Kit
HUAWEI Search Kit fully opens Petal Search capabilities through the device-side SDK and cloud-side APIs, enabling ecosystem partners to quickly provide the optimal mobile app search experience.
Dependencies that needed
Code:
//design
implementation 'com.google.android.material:material:1.2.1'
implementation 'androidx.recyclerview:recyclerview:1.1.0'
implementation 'com.github.bumptech.glide:glide:4.10.0'
//rxJava
implementation 'io.reactivex.rxjava2:rxjava:2.2.19'
implementation 'io.reactivex.rxjava2:rxandroid:2.1.1'
implementation 'com.squareup.retrofit2:retrofit:2.5.0'
implementation 'com.squareup.retrofit2:converter-gson:2.5.0'
implementation 'com.squareup.retrofit2:adapter-rxjava2:2.5.0'
//searchKit HMS
implementation 'com.huawei.hms:searchkit:5.0.4.303'
1. Create a class that extends from Application
Code:
import android.app.Application
import com.huawei.hms.searchkit.SearchKitInstance
class SearchKitApplication: Application() {
override fun onCreate() {
super.onCreate()
// Initialize Search Kit.
SearchKitInstance.init(this, "your_app_id");
}
}
In Manifest in Application tag apply this below line of code
Code:
android:name=".SearchKitApplication"
3. Now we can create an empty activity with this name
SearchActivity. please take a look on important part in references.
or as you like you can modify it, if you would like.
4. In Utils package that we created in point 2, let’s create AnimationUtils class
Code:
public class AnimationUtils {
public static void expand(final View v) {
int matchParentMeasureSpec =
View.MeasureSpec.makeMeasureSpec(((View) v.getParent()).getWidth(), View.MeasureSpec.EXACTLY);
int wrapContentMeasureSpec = View.MeasureSpec.makeMeasureSpec(0, View.MeasureSpec.UNSPECIFIED);
v.measure(matchParentMeasureSpec, wrapContentMeasureSpec);
final int targetHeight = v.getMeasuredHeight();
v.getLayoutParams().height = 1;
v.setVisibility(View.VISIBLE);
Animation a =
new Animation() {
@Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
v.getLayoutParams().height =
interpolatedTime == 1
? ViewGroup.LayoutParams.WRAP_CONTENT
: (int) (targetHeight * interpolatedTime);
v.requestLayout();
}
@Override
public boolean willChangeBounds() {
return true;
}
};
a.setDuration((int) (targetHeight / v.getContext().getResources().getDisplayMetrics().density));
v.startAnimation(a);
}
public static void collapse(final View v) {
final int initialHeight = v.getMeasuredHeight();
Animation a =
new Animation() {
@Override
protected void applyTransformation(float interpolatedTime, Transformation t) {
if (interpolatedTime == 1) {
v.setVisibility(View.GONE);
} else {
v.getLayoutParams().height = initialHeight - (int) (initialHeight * interpolatedTime);
v.requestLayout();
}
}
@Override
public boolean willChangeBounds() {
return true;
}
};
a.setDuration((int) (initialHeight / v.getContext().getResources().getDisplayMetrics().density));
v.startAnimation(a);
}
}
5. Now in network package let’s work on it to can get access token that will let us able to use search kit features
Code:
public class UrlHelper {
/**
* The Content REQUEST_TOKEN.
*/
public static final String REQUEST_TOKEN = "oauth2/v3/token";
// public static final String REQUEST_TOKEN = "oauth2/v2/token/https://logintestlf.hwcloudtest.cn/";
}
Code:
public interface QueryService {
@FormUrlEncoded
@POST(UrlHelper.REQUEST_TOKEN)
Observable<TokenResponse> getRequestToken(
@Field("grant_type") String grantType,
@Field("client_id") String ClientId,
@Field("client_secret") String clientSecret);
}
Code:
public class NetworkManager {
private static final String TAG = NetworkManager.class.getSimpleName();
private static NetworkManager networkManager;
public static NetworkManager getInstance() {
if (networkManager == null) {
syncInit();
}
return networkManager;
}
private static synchronized void syncInit() {
if (networkManager == null) {
networkManager = new NetworkManager();
}
}
public QueryService createService(Context context, String baseUrl) {
QueryService queryService = null;
Retrofit retrofit = null;
Retrofit.Builder builder = new Retrofit.Builder().baseUrl(baseUrl);
OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();
try {
SSLSocketFactory ssf = SecureSSLSocketFactory.getInstance(context);
X509TrustManager xtm = new SecureX509TrustManager(context);
clientBuilder.sslSocketFactory(ssf, xtm);
clientBuilder.hostnameVerifier(new StrictHostnameVerifier());
} catch (IOException e) {
Log.e(TAG, "getRetrofit: " + e.getMessage());
} catch (IllegalAccessException e) {
Log.e(TAG, "getRetrofit: " + e.getMessage());
} catch (NoSuchAlgorithmException e) {
Log.e(TAG, "getRetrofit: " + e.getMessage());
} catch (KeyManagementException e) {
Log.e(TAG, "getRetrofit: " + e.getMessage());
} catch (KeyStoreException e) {
Log.e(TAG, "getRetrofit: " + e.getMessage());
} catch (CertificateException e) {
Log.e(TAG, "getRetrofit: " + e.getMessage());
} catch (Exception e) {
Log.e(TAG, "getRetrofit: " + e.getMessage());
}
OkHttpClient client =
clientBuilder
.retryOnConnectionFailure(true)
.readTimeout(5000, TimeUnit.MILLISECONDS)
.connectTimeout(5000, TimeUnit.MILLISECONDS)
.build();
try {
retrofit =
builder.client(client)
.addConverterFactory(GsonConverterFactory.create())
.addCallAdapterFactory(RxJava2CallAdapterFactory.create())
.build();
queryService = retrofit.create(QueryService.class);
} catch (Exception e) {
Log.e(TAG, "createRestClient error: " + e.getMessage());
}
return queryService;
}
}
6. In bean package, let’s start with create ListBean class
Code:
public class ListBean {
String title;
String url;
String click_url;
public String getClick_url() {
return click_url;
}
public void setClick_url(String click_url) {
this.click_url = click_url;
}
public String getTitle() {
return title;
}
public void setTitle(String title) {
this.title = title;
}
public String getUrl() {
return url;
}
public void setUrl(String url) {
this.url = url;
}
}
Now we will work on create TokenResponse class:
Code:
public class TokenResponse {
String access_token;
Integer expires_in;
String token_type;
public String getAccess_token() {
return access_token;
}
public void setAccess_token(String access_token) {
this.access_token = access_token;
}
public Integer getExpires_in() {
return expires_in;
}
public void setExpires_in(Integer expires_in) {
this.expires_in = expires_in;
}
public String getToken_type() {
return token_type;
}
public void setToken_type(String token_type) {
this.token_type = token_type;
}
}
