Issue in changing orientation in android

Just making a test application that should display a log message on changing orientation, but when i change orientation using ctrl + f11, there is nothing shown in the logcat.
what is the issue in the coding
A Part From Manifest
<activity
android:name="com.example.orientationtest.MainActivity"
android:label="#string/app_name"
android:configChanges="orientation|screenSize" >
A part from Java
package com.example.orientationtest;
import android.os.Bundle;
import android.app.Activity;
import android.content.res.Configuration;
import android.util.Log;
import android.view.Menu;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
// TODO Auto-generated method stub
super.onConfigurationChanged(newConfig);
Log.d("error", " orientation changes");
}
}

try this if target api 13 and above
android:configChanges="orientation|keyboardHidden|screenLayout|screenSize"
or
android:configChanges="orientation|keyboardHidden|screenLayout"
for lower than 13 ..... this will help you... :)

Using configChanges is not a good idea if you only want to know if the screen rotated. It basically means that you plan to handle the whole rotation change by yourself in the code.
If you don't plan to do this, just check what is the current rotation when your Activity is created:
int currentOrientation = getResources().getConfiguration().orientation;
Then just do whatever you want using this check:
if(currentOrientation == Configuration.ORIENTATION_LANDSCAPE){
//if landscape
} else {
//if portrait
}
This way you don't need to touch your manifest file and you let your app manage the configuration changes by itself.
You can keep the previous orientation used in the activity saved instance if you need to compare the previous and the current one.

The issue is that you prevented the android from changing its orientation
android:configChanges="orientation|screenSize"
that line of code is preventing it to configuration change and that why your not getting any response..

How to put Interfaces in a library for android App

to the point, i am working in a library for android app's, all programing part is almost finish, i am testing a idea.
the idea is put some interfaces in the librery that i am working, and this GUI can be loaded in the main app.
i try to do it but i get to error the first was i did not declare the activity in the AndroidManifest in the main app, the second one is the one a i cant solve, the autogenerated Class R don't capture the GUI that it is in the librery.
it is anyway i can do this or it is imposible.
code to see what i am trying todo
in my librery (movilsecure)
EmisionActivity.java (have the activity_emision.xml in the res of my librery)
in the Main Android App (
import ve.com.idyseg.movilsecure.EmisionActivity;
import ve.com.idyseg.movilsecure.MSMasterControllerTEST;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.Menu;
import android.view.View;
import android.widget.TextView;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
public void captureEvent (View v){
Intent intento = new Intent(this,EmisionActivity.class);
startIntent(intento);
}
}

In Eclipses, right click the project, the click Build Path then click Add Library. Please comment if you're still stuck.

In the library's manifest, in the <activity> node, did you set android:exported="true"?
Example:
<activity
android:name="com.example.app.EmisionActivity"
android:exported="true">
</activity>

how to hide the push notification bar in phonegap android

I want to show the application window in full screen where it looks like a game screen...
Please help me..
package play.lear.com;
import org.apache.cordova.DroidGap;
import android.os.Bundle;
import android.view.WindowManager;
public class PlayActivity extends DroidGap {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
super.setIntegerProperty("splashscreen", R.drawable.splash);
super.loadUrl("file:///android_asset/www/index.html", 10000);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FORCE_NOT_FULLSCREEN);
}
}

There's a flag you can set in config.xml for full screen
<preference name="fullscreen" value="true" />

Phonegap's Notification has nothing to do with push notification.

How to prevent double tap (bug?) on Android JB WebView?

I'm trying to port a Flash based game to Android.
I've ported it successfully (WebView), but now, the problem is that when I do a short click (short tap) somewhere in the game, it does 2 clicks (double tap), and when I do a long click (long tap) it does a short click (short tap).This is really annoying, specially when it does double fire instead of one fire. I've tried with the touch screen and a mouse; both had the same issue, so the input isn't the problem.
After reading a lot of stuff I think it must be a bug(?) on Andriod (4.x+ I think) WebView.
I hope you can help me to invert those things or to prevent those double taps as soon as possible.
Here is the code of the MainActivity.java:
package usr.sh.raul.dofus;
import android.annotation.SuppressLint;
import android.app.Activity;
import android.graphics.Color;
import android.os.Bundle;
import android.view.Window;
import android.view.WindowManager;
import android.webkit.WebView;
#SuppressLint("SetJavaScriptEnabled")
public class MainActivity extends Activity
{
WebView mWebView;
/** Called when the activity is first created. */
#SuppressLint("SdCardPath")
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.activity_main);
mWebView = (WebView) findViewById(R.id.webview);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setPluginsEnabled(true);
mWebView.setScrollBarStyle(WebView.SCROLLBARS_OUTSIDE_OVERLAY);
mWebView.setBackgroundColor(Color.parseColor("#000000"));
mWebView.loadUrl("file:///sdcard/Android/data/usr.sh.raul.dofus/data/loader.swf");
}
}
Thank you in advance and sorry for my bad english.

Android App Runtime Error

I have 2 classes for an Android project.
The first class is the Activity and the second class is just a OnClickListener which implements the interface.
If I run the project on my phone I always get an runtime error.
Also I got the message:
The specified activity does not exist! Getting the launcher activity.
Here are my two classes
SendActivity
package kops.sms;
//import android.R;
import android.app.Activity;
import android.os.Bundle;
import android.view.Menu;
import android.widget.Button;
public class SendActivity extends Activity {
Button buttonSend= (Button) findViewById(R.id.buttonSend);
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_send);
buttonSend.setOnClickListener(new ButtonListener());
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.send, menu);
return true;
}
}
and the ButtonListener
package kops.sms;
import android.view.View;
import android.view.View.OnClickListener;
public class ButtonListener implements OnClickListener {
#Override
public void onClick(View v)
{
}
}
I don´t know what is wrong...
I look forward to your replies! :)

You cannot call findViewById() until after you call setContentView(). Please move:
Button buttonSend= (Button) findViewById(R.id.buttonSend);
to after:
setContentView(R.layout.activity_send);
and before:
buttonSend.setOnClickListener(new ButtonListener());
Also, in the future, please use LogCat (e.g., in the DDMS perspective in Eclipse) to examine the Java stack trace associated with your crashes. You would have been told about your NullPointerException, and that may have helped you to fix your problem.

Be sure that your Activity is declared in your manifest. Also, change your onCreate()
public class SendActivity extends Activity {
Button buttonSend;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_send);
buttonSend = (Button) findViewById(R.id.buttonSend);
buttonSend.setOnClickListener(new ButtonListener());
}
You can't call a View such as a Button before you call setContentView() as it exists in your Layout and you haven't inflated your Layout until you call setContentViewe().
If these don't fix your problem then please post Logcat
Edit
Unless I missed it, you need to have all of your Activitys in your manifest. Something like:
<activity
android:name="your.package.name.SendActivity"
// activity attributes such as config changes, lable, etc...
</activity>
Logcat
Logcat output can be one of the most important pieces to determining a crash. It lists what the error was and a line number with activity where the problem occurred. If using Eclipse,
Window-->Show View-->Other-->Android-->Logcat
If you copy/paste the Logcat using coding brackets, it makes getting help much easier. You can also set filters for the logs so you don't get every single message and it is much more manageable. For example, I have a filter with: Filter Name: Runtime, by Log Tag: AndroidRuntime, by Log Level: error. This gives me only error messages for runtime errors/crashes. These filters are on the left side of the logcat view. Hope this helps
