i am new to android environment i have installed eclipse and android developer tool.
my openerp application is running and i coded in "MainActivity.java" in "On create" method that is,
import java.net.MalformedURLException;
import java.net.URL;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import org.apache.xmlrpc.client.*;
import org.apache.xmlrpc.client.XmlRpcClient;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
OpenErpConnect connection=null;
try {
URL loginUrl=new URL("http","192.xxx.x.xx",xxxx,"/xmlrpc/common");
XmlRpcClient client=new XmlRpcClient();
Integer id=(Integer)client.call("login","new_db","admin","123456");
connection=new OpenErpConnect(server,port,db,user,pass,id);
}
catch ( XMLRPCException e) {
Log.d(CONNECTOR_NAME,e.toString());
}
catch ( MalformedURLException e) {
Log.d(CONNECTOR_NAME,e.toString());
}
catch ( ClassCastException e) {
Log.d(CONNECTOR_NAME,e.toString());
}
return connection;
}
i am getting error in line "Integer id=(Integer)client.call("login","new_db","admin","123456");"
Errror is,
The type org.apache.xmlrpc.common.XmlRpcController cannot be resolved. It is indirectly referenced from required .class files
What wrong i am doing i want to get result in android app after connecting from openERP
Hopes for your suggestion
Thanks

I started to use Socketio, and I got a problem. I can't send a simple message to my flask session. My Java code:
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.util.Log;
import android.view.View;
import org.json.JSONException;

public class MainActivity extends AppCompatActivity {
Socket socket;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
try {
socket = IO.socket("http://192.168.8.101:8080/send");
} catch (URISyntaxException e) {
}
}
public void TestButton(View v){
Log.d("send","before send");
JSONObject obj = new JSONObject();
try {
obj.put("message", "hi");
obj.put("binary", new byte[42]);
socket.emit("mes", obj);
} catch (JSONException e) {
e.printStackTrace();
}
}
}
My Python code:
from flask import Flask
from flask_socketio import SocketIO
app = Flask(__name__)
socketio = SocketIO(app)
#socketio.on("mes", namespace="/send")
def chat_message(message):
print("message:")
if __name__ == "__main__":
print("start")
socketio.run(app, host="0.0.0.0", port=8080)
The error:

I hope someone is able to help me with this problem. I've searched everywhere and i can't find my answer.
I think you use python3 with the gevent and gevent-websocket plugin.
gevent-websocket does not support python3 yet.
You have to options here:
Uninstall gevent and gevent-websocket and use eventlet.
Fix the code geventwebsocket/handler.py at line 236.
if b'101' not in self.status:
I hope I could help you.
I am trying to create a code which will convert images into video. I have surfed a lot and find some method to do it using javacv. now i am getting variable not found error in these lines.
recorder.setCodecID( CODEC_ID_MPEG1VIDEO);
recorder.setPixelFormat( PIX_FMT_YUV420P);
I have imported all the jar files into my library as well but still getting this error. Some quick help would be appreciated. I have gone through the below link for the importing the javacv into my workspace.
How to Import JavaCV libraries to Android Project
package com.example.photoaday;
import static com.googlecode.javacv.cpp.opencv_core.cvReleaseImage;
import static com.googlecode.javacv.cpp.opencv_highgui.cvLoadImage;

public class Recordvideo extends Activity {
// #Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.create);
opencv_core.IplImage img = cvLoadImage("/sdcard/folder/img1.jpg");
FFmpegFrameRecorder recorder = new FFmpegFrameRecorder("/sdcard/folder/test.mpeg",200,150);
try {
recorder.setCodecID( CODEC_ID_MPEG1VIDEO);
recorder.setFrameRate(30);
recorder.setPixelFormat( PIX_FMT_YUV420P);
recorder.start();
for (int i=0;i<100;i++)
{
recorder.record(img);
}
recorder.stop();
}
catch (Exception e){
e.printStackTrace();
}
}
}
I assume that your compiler gives error as follows
error: ‘CODEC_ID_MPEG1VIDEO’ was not declared in this scope
error: ‘PIX_FMT_YUV420P’ was not declared in this scope
then solution for error is
change : ‘CODEC_ID_MPEG1VIDEO’ to 'AV_CODEC_ID_MPEG1VIDEO'
change : ‘PIX_FMT_YUV420P’ to 'AV_PIX_FMT_YUV420P'
I tried to run an android project in Cordova with self-build plugin,
Heres the code in JS and java for the plugin
var cordova = require('cordova');
var Carrier = function() {};
Carrier.prototype.getCarrierCode = function(success, error) {
cordova.exec(success, error, 'CarrierPlugin', 'getCarrierCode', []);
};
var carrier = new Carrier();
module.exports = carrier;
this is the java code:
import org.apache.cordova.CordovaPlugin;
import org.apache.cordova.CallbackContext;
import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;
import java.util.Date;
import android.app.Activity;
import android.database.Cursor;
import android.os.Bundle;
import android.provider.CallLog;
import android.content.ContentResolver;
public class CarrierPlugin extends CordovaPlugin{
public static final String TAG = "CarrierPlugin";
public static final String ACTION_GET_CARRIER_CODE = "getCarrierCode";
//public TelephonyManager tm;
#Override
public void initialize(CordovaInterface cordova, CordovaWebView webView) {
// TODO Auto-generated method stub
super.initialize(cordova, webView);
}
#Override
public boolean execute(String action, CordovaArgs args,
CallbackContext callbackContext) throws JSONException{
callbackContext.success("run it");
return true;
}
}
the error I got is "cannot find symbol :"
the strange thing is that, even if I change the code in the CarrierPlugin.java(delete the JSONException in line 16), it reported the same error.
My Eclipse says, you should import CordovaInterface, CordovaWebView and CordovaArgs.
And you might be missing package declaration as well, depending wherever you want to put your plugin's java files, such as:
package com.yourdomain.etc in the very first line of your Java file.
So, I just wanted to use properties-files again, but currently I am just not able to load them! I've already wasted 1h of work just to get this working, but somehow I couldnt. My problem is similar to this one, but Java just doesn't get the file!
Here's my code:
package fast.ProfileManager;
import java.io.FileInputStream;
import java.util.Properties;
import android.app.Activity;
import android.content.Context;
import android.net.wifi.WifiManager;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.CheckBox;
import android.widget.Toast;
public class PMMain extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
String defaultProfileProperties = "defaultProfile.properties";
Properties properties = new Properties();
properties.load(new FileInputStream(defaultProfileProperties));
...
I've already tried to put an "/" infront of the filename, but it didnt work either.
Here's my Project-Directory:
I'm getting an IOException on the line "properties.load ... "
Check out this introduction to using/accessing properties files in Android.
Based on that link, put the properties file in the /assets folder and use the following code:
// Read from the /assets directory
try {
InputStream inputStream = assetManager.open("defaultProfile.properties"");
Properties properties = new Properties();
properties.load(inputStream);
System.out.println("The properties are now loaded");
System.out.println("properties: " + properties);
} catch (IOException e) {
System.err.println("Failed to open microlog property file");
e.printStackTrace();
}
Since I don't own a G1 for development purposes, I am doing my best with the emulator.
This said, I am trying to scan a JPEG image or a PNG image in my sdCard, with the ZXing (Zebra Zrossing) library.
I tried to change the code in the Android project, so it would scan from an image in the sdCard, instead from the camera, without any luck.
What I did next is probably the root of my problem.
I tried to use the JAVASE code, within a new Android Project, to provide an image to the "modified" CommandLineRunner, and here is the thing:
Eclipse would build the project, but won't run it.
The VM log throuws me this message among others:

I searched the web for an answer and I got someone saying that this is common error on the Dalvikvm due to the fact that there is might be a class or library that was precompiled (true, outside Eclipse) and the VM wouldn't be able to use it.

Hai,
I tried to extract the data from the Barcodes and these are the steps i followed.
1.Download ZXing 1.3 and extract it.
2.Add the core/src and androidtest/src from the extracted zxing floder to the android application by setting the property.
use this link to set the property,http://groups.google.com/group/zxing/browse_thread/thread/7d8693e6e42408f2
Now include the following code,
package payoda.android.zxingApp;
import android.app.Activity;
import android.database.CursorJoiner.Result;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.Bundle;
import android.widget.TextView;
import com.google.zxing.BarcodeFormat;
import com.google.zxing.MonochromeBitmapSource;
import com.google.zxing.MultiFormatReader;
import com.google.zxing.Reader;
import com.google.zxing.ReaderException;
import com.google.zxing.qrcode.QRCodeReader;
import com.google.zxing.client.androidtest.*;
import com.google.zxing.common.BaseMonochromeBitmapSource;
public class ZXingApplication1 extends Activity
{
TextView tv;
com.google.zxing.Result result;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
tv=(TextView)findViewById(R.id.text);
Bitmap bitmap = BitmapFactory.decodeResource(getResources(),R.drawable.bar2);
MultiFormatReader reader1=new MultiFormatReader();//For all barcode formats
QRCodeReader reader=new QRCodeReader();//Only for QRCode format
try
{
result=reader1.decode(new RGBMonochromeBitmapSource(bitmap));
tv.setText(result.getText());
}
catch (Exception e)
{
tv.setText("Within Catch block");
}
}
}
This may be helps you.
This is Sean from the project in question.
You are trying to use the code intended for Java SE in Android. Some of the libraries in Java SE are not in Android, like ImageIO.
Look at the code in android/ which uses Android-specific classes to load images.
