BroadcastReceiver not working as I was expecting

I just wrote this small app to show a small Toast everytime the Airplane Mode was changed. It doesn't work
package com.example.android.broadcastreceiverexample;
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.widget.Toast;
import static android.widget.Toast.*;
public class MyReceiver extends BroadcastReceiver{
#Override
public void onReceive(Context context, Intent intent){
makeText(context, "Intent detected", LENGTH_LONG).show();
}
}
Here's the manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
package="com.example.android.broadcastreceiverexample">
<application
android:allowBackup="true"
android:icon="#mipmap/ic_launcher"
android:label="#string/app_name"
android:roundIcon="#mipmap/ic_launcher_round"
android:supportsRtl="true"
android:theme="#style/AppTheme">
<activity android:name=".MainActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<receiver android:name=".MyReceiver" android:exported="true">
<intent-filter tools:ignore="ExtraText">
<action android:name="android.intent.action.AIRPLANE_MODE></action>
</intent-filter>
</receiver>
</application>
</manifest>
Is there something that I am missing here, conceptually or in the code?

Did you declare your activity in the manifest?
If you did, this question was asked before, try the following:
Android Sound not playing in splash screen
How to play audio in splash screen in android

You can try this
MediaPlayer player = new MediaPlayer();
player.setDataSource("/sdcard/audiotrack.mp3");
player.prepare();
player.start();

I have created an android app in eclispe. when i install i got two apps installed

Friends,
I Have created an android file in eclipse and Exported as an android file. When i install it i got two android files. I have two java files in the app. one is second.java and the other is first.java.
When i install the app in blue stacks , it installed two files . One is first and other is second.
I have a button in my first.java which goes to the second.java file. How can i solve it by installing only one app in app tray...???
Here is my code
first.java
package com.zacter;
import android.os.Bundle;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class first extends Activity {
Button button;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
addListenerOnButton();
}
#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 addListenerOnButton(){
final Context context=this;
button=(Button) findViewById(R.id.continuebutton);
button.setOnClickListener(new OnClickListener(){
public void onClick(View arg0) {
Intent intent = new Intent(context,second.class);
startActivity(intent);
}
});
}
}
Second.java
package com.zacter;
import android.os.Bundle;
import android.app.Activity;
import android.view.Menu;
public class second extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_boostram);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.boostram, menu);
return true;
}
}

</activity>
</application>
</manifest>

Replace 'LAUNCHER' with 'DEFAULT'
See here for further explaination

In your manifest files, you are having more than one activities with the intent filter category as launcher.
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
The intent category means you are going to have two launcher icons, or two launch points for your application.
You can read more about it here
http://developer.android.com/guide/topics/manifest/category-element.html

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.zacter"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<application
android:allowBackup="true"

<activity
android:name="com.zacter.MainActivity"
android:label="#string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.zacter.SettingsActivity"
android:label="#string/title_activity_settings"
android:parentActivityName="android.app.LauncherActivity" >
<meta-data
android:name="android.support.PARENT_ACTIVITY"
android:value="android.app.LauncherActivity" />
</activity>
<activity
android:name="com.zacter.Boostram"
android:label="#string/title_activity_boostram" >
</activity>
</application>
</manifest>

just Because of these lines.
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
keep this intent filter for only one activity which you want to launch at starting. if you keep category launcher for any other activities it will creates multiple launcher icons in applications. for more details check this link here

Keep this tag in only first activity remove from Boostram activity tag
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>

<category android:name="android.intent.category.LAUNCHER" /> will create launcher activity, so if you have multiple LAUNCHER category in AndroidManifest.xml file, multiple launcher activity will generate.
Modify your AndroidManifest.xml like below.
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".first"
android:label="#string/title_activity_main" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".second"
android:label="#string/title_activity_main" >
</activity>
</application>

starting point cannot be resolved into a type

So I'm building my very first android app. Trying to get my splash screen to work. But Splash.java is showing an error " StartingPoint cannot be resolved to a type.
Here is my manifest
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.arjun.add"
android:versionCode="1"
android:versionName="1.0" >

android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".StartingPoint"
android:label="#string/app_name" >
<intent-filter>
<action android:name="com.arjun.add.StartingPoint" />
<category android:name="android.intent.category.DEDAULT" />
</intent-filter>
</activity>
</application>
</manifest>
And here is my Splash.Java
package com.arjun.add;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class Splash extends Activity {
#Override
protected void onCreate(Bundle ArjunSharma) {
// TODO Auto-generated method stub
super.onCreate(ArjunSharma);
setContentView(R.layout.splash);
Thread timer = new Thread (){
public void run(){
try{
sleep(5000);
} catch (InterruptedException e){
e.printStackTrace();
}finally{
Intent openStartingPoint = new Intent(Splash.this, StartingPoint.class );
startActivity(openStartingPoint);
}
}
};
timer.start();
}
}
Hope you guys can help me out

try this one:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.arjun.add"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="17" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.arjun.add.Splash"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.arjun.add.MainActivity"
android:label="#string/app_name" >
</activity>
</application>
</manifest>
EDIT: note that put MainActivity as your starting point, that is first activity after splash screen
hope it helps

In your manifest defining StartingPoint you have the category defined as android.intent.category.DEDAULT, should be android.intent.category.DEFAULT.

Cannot get to launch the searchable activity

manifest code for the built in search, using the searchview.
can anyone tell me please what is wrong with it?
the SearchableActivity is created in the scr -> presentation, and it is using an xml layout called search.xml. I am new to android and can't find out what is wrong with my code. when launching the search view typing a word and press on "Go" on the keyboard the debugger opens a ActivityThread.perfor.... and tells me source not found.

Try adding the below in your <intent-filter>.
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />

I think, your activity is not visible outside your Application.
Try android:exported="true".
