I am working on a project in android studio. The application is a client that connects to host written in c# using sockets. I am new to java this being my first project I am doing on my own. I am used with sockets in c# and in java I found a lot of similarities, but I encountered a strange problem: everything is fine until a new socket is initialized when the code execution seems to be interrupted. I will post the code than I will explain exactly what is happening.
First part, the main thread:
package com.example.alexandru.news;
import android.app.Activity;
import android.content.Context;
import android.os.Build;
import android.support.v7.app.ActionBar;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.telecom.Connection;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
import java.io.DataOutputStream;
import java.io.IOException;
import java.io.InterruptedIOException;
import java.net.Socket;
import java.net.UnknownHostException;
public class login extends Activity {
EditText emadr;
EditText pasword;
Button log_in_butt;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_login);
log_in_butt = (Button) findViewById(R.id.login);
emadr= (EditText) findViewById(R.id.EmailAdr);
pasword= (EditText) findViewById(R.id.Password);
}
public void loginOnClick(View v)
{
final String mesaj=emadr.getText().toString()+"%"+pasword.getText().toString()+"%"+"^STOP^";
String[] perm={"android.permission.CAMERA"}; int a=200;
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
requestPermissions(perm,a);
}
com.example.alexandru.news.Connection log_in_connection=new com.example.alexandru.news.Connection(mesaj);
log_in_connection.start();
}
}
The connection class is a class I created in the same folder with the "log in" class(the main class). The code behind the Connection class:
package com.example.alexandru.news;
import android.content.Context;
import android.util.Xml;
import android.widget.Toast;
import java.io.DataOutputStream;
import java.io.IOException;
import java.net.Socket;
import java.net.SocketAddress;
import java.net.UnknownHostException;
/**
* Created by Alexandru on 14.08.2016.
*/
public class Connection extends Thread {
String ip="some ip";
int port=60000;
String mesaj;
Socket soc;
public Connection(String mesaj) {
this.mesaj=mesaj;
}
#Override
public void run() {
try {
int a=2;
soc= new Socket(ip, port);
DataOutputStream outstream =new DataOutputStream(soc.getOutputStream());
byte[] buffer;
buffer = this.mesaj.getBytes("UTF-8");
outstream.write(buffer);
outstream.flush();
outstream.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}
When I run the app and I press the button everything is executed until the statement =new Socket(ip,port) is met when this happen the thread isn't executing anymore (I think). When I am debugging and the breakpoint is set before that problematic line everything works. When that line is highlighted and I press F8 the debugging tab says: "Application is running" and then pressing F8 again doesn't make any changes. If I press the "log in" button again nothing happens.
I am using a USB device to debug the app which is connected to the same network as the PC trough WiFi.No port forward is made. I worked with sockets in a project with my high school team before and we had a java client and a c# host and everything worked. But we were using the Emulator. I used all the ip addresses "ipconfig" gave me I changed the port, nothing happens. It doesn't work. I seems that I am the only one with this problem. Sorry for long post and lack of details.

Application terminated.
App crashes because you are calling Toast in background thread.
Replace your Toast line in catch block Toast.makeText(MainActivity.this, "URL malfunctioned", Toast.LENGTH_SHORT).show(); with :
new Handler(Looper.getMainLooper()).post(new Runnable() {
#Override
public void run() {
Toast.makeText(MainActivity.this, "URL malfunctioned", Toast.LENGTH_SHORT).show();
}
});
Just delete the Toast.makeText
I want to show the floating layout on top of the screen when service Alarm or Call happened. Normally, when the app opens or it is in the background (before swiping it out) it shows and works well. even if I kill the app it still shows (kill = swipe the app)and it is still working. but, if the app is killed and not opened it tries to show (from service of alarm for example) it crashes and I cant even see the crash log in the android studio after terminating the app.
how can I fix that or find the issue?
my code Alarm BroadCast where it called: (the alarm broadcast called as needed)

Intent intent = new Intent(context,FloatingWindow.class);

Under certain circumstances, a background app is placed on a temporary whitelist for several minutes. While an app is on the whitelist, it can launch services without limitation, and its background services are permitted to run. An app is placed on the whitelist when it handles a task that's visible to the user, such as:
Handling a high-priority Firebase Cloud Messaging (FCM) message.
Receiving a broadcast, such as an SMS/MMS message.
Executing a PendingIntent from a notification.
Starting a VpnService before the VPN app promotes itself to the foreground.

Can anyone help here..stuck at this for days now..Thanks
Does android run some special mobile version of java? It seems like the 4.2 http components are likely not compatible. I haven't had a chance to look into it much, but I wonder if there is a newer set of those components that are compatible with the android environment? You could try forking the RallyRestToolkitForJava repo and updating the dependencies locally to see if you can get it to run...
There's a class conflict with the included Apache HTTP jars and the ones used by native Android. I got around this by forking the Rally project and replacing Apache HTTP with OKHttp to remove the conflict. My changes are in my fork in github: https://github.com/rawslaw/RallyRestToolkitForJava
I'm try to play a loading animation on my loading screen, and I read somewhere that android doesn't support gifs so either you have to break in into frames and then play it or we can use the Movie class.
Heres the leading activity -

});
AlertDialog alert = builder.create();
alert.show();
}
}
In the above code I've set content view by passing it an instance of MYGIFView.class -
Heres MYGIFView.class
package com.myapp.mehul.login;
import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Movie;
import android.view.View;
import java.io.InputStream;
/**

*/
public class MYGIFView extends View{
Movie movie,movie1;
InputStream is=null,is1=null;
long moviestart;
public MYGIFView(Context context) {
super(context);
is=context.getResources().openRawResource(+ R.drawable.loading);
movie=Movie.decodeStream(is);
}
#Override
protected void onDraw(Canvas canvas) {
canvas.drawColor(Color.WHITE);
super.onDraw(canvas);
long now=android.os.SystemClock.uptimeMillis();
System.out.println("now="+now);
if (moviestart == 0) { // first time
moviestart = now;
}
System.out.println("\tmoviestart="+moviestart);
int relTime = (int)((now - moviestart) % movie.duration()) ;
System.out.println("time="+relTime+"\treltime="+movie.duration());
movie.setTime(relTime);
movie.draw(canvas,this.getWidth()/2-20,this.getHeight()/2-40);
this.invalidate();
}
}
The loading activity IS creating an instance of MYGIFView.class and it logs the data but then it gives fatal signal 11. I tried to search but I didn't get any answer.

I received a batch for this question which means its being viewed a lot, so I'll answer this question -
What I figured out was the line below was throwing the error -
movie.draw(canvas,this.getWidth()/2-20,this.getHeight()/2-40);
Now the problem is that this error specifically can be caused by lots of reasons, its never a specific reason.. the reason mine wasn't working out was because my device didn't work well with hardware acceleration, so I just had to disable it in the manifest application, like this -
<android:hardwareAccelerated="false">
Now its possible that the reason might not be the same....but the core reason is the same, its memory related, and most chances are its a bug in the firmware of the device or emulator you are testing upon.
In the Manifest set in your activity :
<activity
android:name="LoadingScreen"
android:hardwareAccelerated="false">
</activity>
I got here with the exact same problem but in React Native, so I will put a solution for those who need it too. The error may be triggered by react-native-webview and/or React Navigation. In some cases, like me, you don't want to disable Hardware Acceleration on the whole app, so here's a workaround:
react-native-webview
<WebView
androidHardwareAccelerationDisabled
source={source}
/>
React Navigation 5
<NavigationContainer>
<Stack.Navigator initialRouteName="HomeScreen">
<Stack.Screen
name="HomeScreen"
component={HomeScreen}
options={{
animationEnabled: false,
}}
/>
</Stack.Navigator>
</NavigationContainer>

I am developing an app which includes the upload of all contacts to my server what i am doing is displaying all the contacts and sending them to my server as a string.Here is my code:

Actually the code shows no error but on running it in emulator it crashes.
the error on logcat is:

As error code state, you need to encode the query:
HttpPost httppost = new HttpPost("http://192.168.2.30/b.php?username="+params);
need to changed into:
HttpPost httppost = new HttpPost("http://192.168.2.30/b.php?username="+java.net.URLEncoder.encode(params[0], "UTF-8"));
