Sending data to fragment from service

i have a string in my service, and i want to send it to fragment. But it seems onReceive() method on my BroadcastReceiver never called, and i just can't figured out why. Thanks for answers.
My Service Class
public class Servis extends Service {
static final String MAP = "MyService";
static final String USERID = "";
public static final String FILEPATH = "filepath";
#Override
public int onStartCommand(Intent intent, int flags, int startId)
{
System.out.println("starting service");
Toast.makeText(this, "service starting", Toast.LENGTH_SHORT).show();
String id = intent.getStringExtra("UserID");
System.out.println(id);
Intent intent1 = new Intent(MAP);
intent1.putExtra(USERID, id);
sendBroadcast(intent1);
return START_REDELIVER_INTENT;
}
#Override
public IBinder onBind(Intent intent) {
return null;
}
#Override
public void onCreate() {
Toast.makeText(this, "My Service Created", Toast.LENGTH_LONG).show();
Log.d(MAP, "onCreate");
}
#Override
public void onDestroy() {
Toast.makeText(this, "My Service Stopped", Toast.LENGTH_LONG).show();
Log.d(MAP, "onDestroy");
}
#Override
public void onStart(Intent intent, int startid) {
Toast.makeText(this, "My Service Started", Toast.LENGTH_LONG).show();
Log.d(MAP, "onStart");
}
}

Cannot redirect to next page

Here is my Home.java code. It is not redirecting to next page, even if I change the intent to (home.this, MainActivity.class):

e.printStackTrace();
} finally {
Intent openMainActivity = new Intent("com.droid.mine.MainActivity");
startActivity(openMainActivity);
}
}
};
timer.start();}{

}
Here is my MainActivity.java code. I.e next page
I am getting the error as ClassCastException:

import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class Register extends Activity implements View.OnClickListener {
Button backlog,regg;
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.login);

public void onClick (View v)

case R.id.loginn:
break;
case R.id.signup:
Intent in = new Intent();
in.setClass(Register.this,MainActivity.class);
startActivity(in);
break;
}
}
}

Firstly
Change where you intent with this:
Intent intent = new Intent(Home.this,MainActivity.class);
startActivity(intent);
Secondly
Just update your manifest with this:
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.droid.mine.Home"
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.droid.mine.MainActivity"
android:label="#string/app_name" >
</activity>
<activity
android:name="com.droid.mine.Register"
android:label="#string/app_name" >
</activity>
</application>
Use this as home activity
package com.example.pms;
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.os.Bundle;
import android.os.Handler;
import android.view.MotionEvent;
import android.widget.Toast;
public class SplashScreen extends Activity {
/*
* The thread to process splash screen events
*/
private Thread mSplashThread;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// splash screen view
setContentView(R.layout.activity_splash);
final SplashScreen mSplashScreen=this;
/*
* The thread to wait for splash screen events
*/
mSplashThread =new Thread(){
#Override
public void run(){
try {
synchronized(this){
// Wait given period of time or exit on touch
wait(3000);
}
}
catch(InterruptedException ex){
}
finish();
// Run next activity
startActivity(new Intent(getBaseContext(), MainActivity.class));
new Runnable() {
#Override
public void run() {
mSplashThread.stop();
}
};
}
};
mSplashThread.start();
}
/**
* Processes splash screen touch events
*/
#Override
public boolean onTouchEvent(MotionEvent event) {
if(event.getAction() == MotionEvent.ACTION_DOWN)
{
synchronized(mSplashThread){
mSplashThread.notifyAll();
}
}
return true;
}
}

you can use this code instead
replace
.MainActivity
with
com.droid.mine.MainActivity
while declaring in Manifest file.
//delay in ms
int DELAY = 1000;
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
#Override
public void run() {
Intent intent = new Intent(Home.this,MainActivity.class);
startActivity(intent);
}
}, DELAY);

Change your Intent to:
Intent openMainActivity = new Intent(Home.this, MainActivity.class);
startActivity(openMainActivity);
and in manifest file use:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.testapp"
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.example.testapp.Home"
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=".MainActivity"
android:label="#string/app_name" >
</activity>
</application>
</manifest>

You need to register MainActivity and Register Activity in the manifest:
<activity android:name=".Mainactivity" />
<activity android:name=".Register" />
log.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
});
}
sign.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
Intent i = new Intent();
i.setClass(MainActivity.this,Register.class);
startActivity(i);
});
}

I hope this works:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class Home extends Activity{
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.fragment_main);
Thread splashTimer = new Thread() {
public void run() {
try {
int splashTimer = 0;
while (splashTimer < 2000) {
sleep(100);
splashTimer = splashTimer + 100;
}
Intent intent;
intent = new Intent(Home.this, MainActivity.class);
startActivity(intent);
finish();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
Log.d("asd","dasd");
}
finally {
finish();
}
}
};
splashTimer.start();
}
}
Edit: Replace your manifest file with this, now I hope it works:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.droid.mine"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="19" />
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.droid.mine.Home"
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.droid.mine.MainActivity"
android:label="#string/app_name" >
</activity>
</application>
</manifest>

Splash and main activity error

Can someone please help. After the splash activity, the main activity isn't opening up. But if I put in any other intent filter name it works Just not the main activity. Thanks in advance!

Try this in your Splash Activity..
Intent yo = new Intent (Splash.this, MainActivity.class);
startActivity(yo);
In your manifest file
<activity
android:name="com.hellhog.tfreqpro.MainActivity"
android:label="#string/app_name"
android:screenOrientation="portrait" >
<intent-filter>
<action android:name="android.intent.action2.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
delete the following lines of intent filtter
<intent-filter>
<action android:name="android.intent.action2.MAINACTIVITY" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>

Here is what working for me perfectly !
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE); // Removes title bar
this.getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN); // Removes notification bar
setContentView(R.layout.splashscreen);
// Start timer and launch main activity
IntentLauncher launcher = new IntentLauncher();
launcher.start();
}
private class IntentLauncher extends Thread {
#Override
/**
* Sleep for some time and than start new activity.
*/
public void run() {
try {
// Sleeping
Thread.sleep(SLEEP_TIME*1000);
} catch (Exception e) {
Log.e(TAG, e.getMessage());
}
// Start main activity
Intent intent = new Intent(SplashActivity.this,FullscreenActivity.class);
SplashActivity.this.startActivity(intent);
SplashActivity.this.finish();
}
}

Try to use below code..
public class SplashScreenextends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.splashscreen);
Handler handler = new Handler();
handler.postDelayed(new Runnable() {
public void run() {
// TODO Auto-generated method stub
finish();
Intent menu = new Intent(getBaseContext(), MainActivity.class);
startActivity(menu);
}
}, 3000);
}
}
It will set your SplashScreen for 3 seconds and then starts your mainactivity or whatever activity you want to start.MAy it helps you..

android.content.ActivityNotFoundException: No Activity found to handle Intent splash screen

I am having an issue with loading up a new intent after my splash screen. I have looked at questions relating to this exception but they all seem to be dealing with thing like google play or google maps not being referenced correctly this is not the case for me.
These are the related questions I have looked at
Not found activity to handle intent?

Below is my manifest code

Here is the code for the class splash
package com.android.main;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
public class Splash extends Activity{
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

Thread timer = new Thread(){
public void run(){
try{

}finally{

startActivity(openStartingPoint);
}
}
};
timer.start();
}
#Override
protected void onPause() {
super.onPause();
finish();
}
}
And here is the class HomePage I am trying to load after the splash screen
package com.android.main;

EditText editName;
TextView drinks;
Spinner drinksSpinner;
TextView message;
CheckBox checkbox;
Button createOrderButton;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

}
public void createOrder(){

}
The app force quits after loading the splash screen and gives the following exception
03-14 22:32:33.553: E/AndroidRuntime(3166): android.content.ActivityNotFoundException: No Activity found to handle Intent { act=com.android.main.HOMEPAGE }
Any help with this would be greatly appreciated

You have to differentiate the Intent's Constructor,
Intent openStartingPoint = new Intent("com.android.main.HOMEPAGE");
Which assume com.android.main.HOMEPAGE as Intent's action Filter. Which is not available in your application's android manifest.xml file. You have
<action android:name="android.intent.action.HOMEPAGE" />
which should be,
<action android:name="com.android.main.HOMEPAGE" />
OR just change it with,
Intent openStartingPoint = new Intent(Splash.this, HOMEPAGE.class);

<activity
android:label="#string/app_name"
android:name=".SplashScreen"
android:screenOrientation="landscape"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen" >
<intent-filter >
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name="com.android.main.HOMEPAGE"
android:screenOrientation="landscape"
android:theme="#android:style/Theme.NoTitleBar.Fullscreen" >
<intent-filter >
<action android:name="com.android.main.HOMEPAGE" />
<category android:name="android.intent.category.DEFAULT" />
</intent-filter>
</activity>
Also i would have a timer task to display splash screen
public class SplashScreen extends Activity{
Timer splashTimer;
SplashTimerHandler splashTimerHandler;
private boolean applicationPaused=false;
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.main);
this.setSplash();
}
private void setSplash()
{
this.splashTimerHandler=new SplashTimerHandler();
this.splashTimer=new Timer();
this.splashTimer.schedule(this.splashTimerHandler, 0, 1000);
}
#Override
public void onPause()
{
super.onPause();
this.applicationPaused=true;
this.closeSplashTimer();
}
#Override
public void onResume()
{
super.onResume();
if(this.applicationPaused)
{
this.applicationPaused=false;
this.closeSplashTimer();
this.setSplash();
}
}
public class SplashTimerHandler extends TimerTask{
int splashTimerCounter=0;
#Override
public void run()
{
splashTimerCounter++;
if(splashTimerCounter>2)
{
runOnUiThread(splashTimeOver);
}
}
private Runnable splashTimeOver=new Runnable() {
#Override
public void run()
{
closeSplashTimer();
startHomeScreen();
}
};
}
protected void closeSplashTimer()
{
if(this.splashTimer!=null)
{
this.splashTimer.cancel();
this.splashTimer=null;
}
}
private void startHomeScreen()
{
this.closeSplashScreen();
startActivity(new Intent("com.android.main.HOMEPAGE"));
}
private void closeSplashScreen()
{
this.closeSplashTimer();
this.finish();
}
#Override
public boolean onKeyDown(int keycode, KeyEvent event)
{
if(keycode==KeyEvent.KEYCODE_BACK)
{
this.closeSplashScreen();
}
return true;
}
}

how to start the app on power button press

I want to start my app when a user press the power button. I m following This code
but its not showing any Log and toast.
here is my complete code.
MyReceiver.java
import android.content.BroadcastReceiver;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;
public class MyReceiver extends BroadcastReceiver {
#Override
public void onReceive(Context context, Intent intent) {
// TODO Auto-generated method stub
Log.v("onReceive", "Power button is pressed.");
Toast.makeText(context, "power button clicked", Toast.LENGTH_LONG)
.show();
// perform what you want here
}
}

}
#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;
}
}
I think i m committing a mistake in my menifest file. please have a look on this. thanks.

First, unlike other broad casted intents, for Intent.ACTION_SCREEN_OFF and Intent.ACTION_SCREEN_ON you CANNOT declare them in your Android Manifest! so You need to make a service which will keep on running like this
public static class UpdateService extends Service {
#Override
public void onCreate() {
super.onCreate();
// register receiver that handles screen on and screen off logic
IntentFilter filter = new IntentFilter(Intent.ACTION_SCREEN_ON);
filter.addAction(Intent.ACTION_SCREEN_OFF);
BroadcastReceiver mReceiver = new Receiver();
registerReceiver(mReceiver, filter);
}
#Override
public void onStart(Intent intent, int startId) {
boolean screenOn = intent.getBooleanExtra("screen_state", false);
if (!screenOn) {
// your code
} else {
// your code
}
}
}
and your receiver can be something
public class Receiver extends BroadcastReceiver {
private boolean screenOff;
#Override
public void onReceive(Context context, Intent intent) {
if (intent.getAction().equals(Intent.ACTION_SCREEN_OFF)) {
screenOff = true;
} else if (intent.getAction().equals(Intent.ACTION_SCREEN_ON)) {
screenOff = false;
}
Intent i = new Intent(context, UpdateService.class);
i.putExtra("screen_state", screenOff);
context.startService(i);
}
}

Here is my complete code. Hope this helps. I was basically making a look screen app. This will disable your default lock screen. and on power button press it will start a service and runs to look for power button press event.

Here this one is the complete code, which will open your application as soon you presss power button. I am also doing the same project, where i want to open my Application directly after i press power button (turn on).
