Unable to find explicit activity class {}; have you declared this activity in your AndroidManifest.xml

I'm trying unzip some files in background, so I use IntentService like in google's tutorial. My service class declared in AndroidManifest like this:
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="org.osmdroid">
<uses-sdk
android:minSdkVersion="16"
android:targetSdkVersion="21" />
<application
android:configChanges="orientation|screenSize|keyboardHidden"
android:hardwareAccelerated="true"
android:icon="#drawable/ecn_icon"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name=".MapActivity"
android:icon="#drawable/ecn_icon"
android:label="test" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
<activity
android:name=".SettingsActivity"
android:label="#string/title_activity_settings">
</activity>
<service
android:name=".UnZipService"
android:exported="false"/>
</application>
In activity, I have
IntentFilter intentFilter = new IntentFilter(DownloadManager
.ACTION_DOWNLOAD_COMPLETE);
receiverDownloadComplete = new BroadcastReceiver() {
#Override
public void onReceive(Context context, Intent intent) {
long reference = intent.getLongExtra(DownloadManager
.EXTRA_DOWNLOAD_ID, -1);
if (myDownloadReference == reference) {
...
switch (status) {
case DownloadManager.STATUS_SUCCESSFUL:
Intent mServiceIntent = new Intent(context, UnZipService.class);
mServiceIntent.setData(Uri.parse(savedFilePath));
startActivity(mServiceIntent);
break;
...
}
cursor.close();
}
}
};
registerReceiver(receiverDownloadComplete, intentFilter);
And service here:
public class UnZipService extends IntentService {
public UnZipService() {
super("UnZipService");
}
#Override
protected void onHandleIntent(Intent workIntent) {
String dataString = workIntent.getDataString();
Log.v("IntentURI", dataString);
Toast.makeText(this, "Installing....", Toast.LENGTH_SHORT).show();
}
It should show toast just for test, but I always get an error:

Both (class and activity) in same folder (org.osmdroid). Seems like paths is ok, but the problem appears and I have no more ideas...

You are starting a service as an activity
Change
Intent mServiceIntent = new Intent(context, UnZipService.class);
mServiceIntent.setData(Uri.parse(savedFilePath));
startActivity(mServiceIntent);
to
Intent mServiceIntent = new Intent(context, UnZipService.class);
mServiceIntent.setData(Uri.parse(savedFilePath));
startService(mServiceIntent); // Only this line is changed

Please declared this activity in your AndroidManifest.xml

Unable to instantiate activity ComponentInfo, android using java

UPDATE
Like an idiot I did not pay attention to the logCat.
The problem was coming from the page I was navigating to, not the intent itself, I was declaring some code before the setContentView code has a chance to run within onContentLoad().
Thanks for all the help!
I know this question has been asked before, but I have followed numerous posts about this topic; but can't seem to find the right answer.
I am trying to navigate from my MainActivity page, to my ViewFeeds page; but it is throwing the above error.
The funny thing is, I have already got the code to navigate between pages, and it works. But when I come to duplicate this code for another class, it throws the above error.
MainActivity Code (The one I am navigating from):
public void btnFeedsClick(View v)
{
Button button = (Button) findViewById(R.id.button3);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MainActivity.this, ViewFeeds.class);
MainActivity.this.startActivity(intent);
}
});
}
The ViewFeeds class (The one I am navigating to):
package com.example.rssapplication;
import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.util.ArrayList;
import android.app.ActionBar;
import android.app.Activity;
import android.os.Bundle;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import android.widget.TextView;
public class ViewFeeds extends Activity{
//The array which holds all of the data...
ArrayList<String> items = new ArrayList<String>();
ListView lv = (ListView) findViewById(R.id.listView1);
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.viewfeeds);
ActionBar actionBar = getActionBar();
actionBar.hide();
items = new ArrayList<String>();
String ret = "";
try {
InputStream inputStream = openFileInput("Teams.txt");
InputStreamReader inputStreamReader = new InputStreamReader(inputStream);
BufferedReader bufferedReader = new BufferedReader(inputStreamReader);
String receiveString = "";
StringBuilder stringBuilder = new StringBuilder();
// Toast.makeText(MainActivity.this, receiveString, Toast.LENGTH_LONG).show();
try {
while ( (receiveString = bufferedReader.readLine()) != null ) {
items.add(receiveString);
stringBuilder.append(receiveString + "\r\n");
}
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
inputStream.close();
//ret holds each line of text from the file...
ret = stringBuilder.toString();
TextView txt = (TextView) findViewById(R.id.textView6);
txt.setText(ret);
ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(
this,
android.R.layout.simple_list_item_1,
items);
lv.setAdapter(arrayAdapter);
} catch (FileNotFoundException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}

The problem is this:
ListView lv = (ListView) findViewById(R.id.listView1);
You are calling findViewById() too early! You always have to be aware of the Activity Lifecycle! findViewById() can only be called after you set a layout with setContentView().
You should look for Views in onCreate() like this:
public class ViewFeeds extends Activity {
private ArrayList<String> items = new ArrayList<String>();
private ListView lv;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.viewfeeds);
lv = (ListView) findViewById(R.id.listView1);
...
}
...
}

1st problem declare this inside onCreate(...) after setContentView(R.layout.ur_layout)
ListView lv = (ListView) findViewById(R.id.listView1);
2nd problem as your application's android:minSdkVersion="8" you should use
ActionBar actionBar = getSupportActionBar();
instead of Activity you have to extends ActionBarActivity of appcompat v7 support library
ActionbarActivity

Android: Activity not found to handle intent

I get this error when I run my program. It starts up the first page, but when it's supposed to go to .Menu it crashes:

And here are the .java files of my .Splash activity and my .Menu activity:
Splash
package com.example.secondapp;

import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
public class Splash extends Activity {
MediaPlayer ourSong;
#Override

// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.splash);
ourSong = MediaPlayer.create(Splash.this, R.raw.happyman);
ourSong.start();
Thread timer = new Thread(){
public void run(){

} catch (InterruptedException e){
e.printStackTrace();
}finally{
Intent startMain = new Intent("com.example.secondapp.MENU");
startActivity(startMain);
}
}
};
timer.start();
}
#Override
protected void onPause() {
// TODO Auto-generated method stub
super.onPause();
finish();
}
}
Menu
package com.example.secondapp;
public class Menu extends ListActivity {
String classes[] = {"MainActivity", "example1", "example2", "example3", "example4", "example5"};
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setListAdapter(new ArrayAdapter<String>(Menu.this, android.R.layout.simple_list_item_1, classes));
}
#Override
protected void onListItemClick(ListView l, View v, int position, long id) {
// TODO Auto-generated method stub
String Cheese = classes[position];
super.onListItemClick(l, v, position, id);
try{
Class ourClass = Class.forName("com.example.secondapp." + Cheese);
Intent ourIntent = new Intent(Menu.this, ourClass);
startActivity(ourIntent);
}catch(ClassNotFoundException e){
e.printStackTrace();
}
}
}

in your manifest the action should match. Change it with com.example.secondapp.MENU

It is in caps MENU should be Menu
Change to
Intent startMain = new Intent("com.example.secondapp.Menu");
coz your activity is public class Menu extends ListActivity { and in manifest you have
<activity
android:name=".Menu"
Edit:
Explicit intents designate the target component by its name (the
component name field, mentioned earlier, has a value set). Since
component names would generally not be known to developers of other
applications, explicit intents are typically used for
application-internal messages — such as an activity starting a
subordinate service or launching a sister activity.
Implicit intents do not name a target (the field for the component
name is blank). Implicit intents are often used to activate
components in other applications.
So Change to explicit intent
Intent startMain = new Intent(Splash.this,Menu.class); // in Splash.java
and in manifest
<activity
android:name="com.example.secondapp.Menu"
android:label="#string/app_name" >
</activity>
For more info check the docs
http://developer.android.com/guide/components/intents-filters.html

You need to set activity class in your manifest and you misspelled MENU
replace
<activity
android:name=".Menu"
android:label="#string/app_name" >
with
<activity
android:name=".MENU"
android:label="#string/app_name" >

int progress = (int) ((i / (float) count) * 100);
publishProgress(progress);

super.onProgressUpdate(values);
progressBar.setProgress(values[0]); // This is ran on the UI thread so it is ok to update our progress bar ( a UI view ) here
}

super.onPostExecute(result);
finishedListener.onTaskFinished(); // Tell whoever was listening we have finished
}
}

change
new LoadingTask(progressBar, null).execute("www.google.co.uk");
to
new LoadingTask(progressBar, this).execute("www.google.co.uk");
I think the second param should be a LoadingTaskFinishedListener.

Fatal exception: main android eclipse

I have viewed most of the other threads regarding this error but have not found an answer.
I started a new project a couple of weeks ago using a plugin and the example project with the plugin. Added various of my own features and designs and no problems running the project.
Then updated to ADT 17 2 days ago and this seriously messed things up for me. Started getting class path errors to name a few. I then reverted back to adt 16 which fixed the errors and my project compiles fine but as soon as i run it it crashes on the test device.
I have checked that my compliance level is correct, checked library paths, api versions, manifest xml, basically everything. I do not get how something that use to work perfectly can now just not work.
I proceeded to unistall everything and did a reinstall on the sdk's ADT and java, but to no avail, even just trying to run the example project just crashes.
I have aslo uninstalled the app from the device and rbooted the device and cleared the cache. I am at the end of my rope. Like i say, i have checked libraries and everything, its just this runtime error.
I also increased the connection time out, and added "android:installLocation="preferExternal" to my manifest, no change.
Please help, there cant be an issue with the code as it worked perfectly.

For me, when I installed ADT 17 I have problems using 3rd party libraries (It kept telling me there were duplications). It turns out that they no longer need to be added to the build path; just kept in a folder in the root of your project called "libs". Could this be the same problem?
