Change
<activity android:name=".rss.RssService" />
to
<service android:name=".rss.RssService" />
And if you want to start service use method
startService(Intent);
by
startActivity(Intent);

You need to call a different method for services:
Intent loader_rssnik = new Intent(this, RssService.class);
startService(loader_rssfuji);

Switch to DIAL_PHONE, as that does not need a permission.
Just replace this line
Intent callIntent = new Intent(Intent.ACTION_CALL);
to
Intent callIntent = new Intent(Intent.ACTION_DIAL);

Android 6 (SDK 23) allows users to revoke permissions from an app. I guess, thats what happened here. Your app must be able to cope with this situation.
Have a look at the documentation for the details.
In particular:
If the device is running Android 6.0 or higher, and your app's target SDK is 23 or higher: The app has to list the permissions in the manifest, and it must request each dangerous permission it needs while the app is running. The user can grant or deny each permission, and the app can continue to run with limited capabilities even if the user denies a permission request.
Requsting permissions at runtime is described in detail here.

Add this permission in the manifest file:
<uses-permission android:name="android.permission.CALL_PHONE"/>
or else try this too.
<uses-permission android:name="android.permission.CALL_PRIVILEGED"/>
CALL_PRIVILEGED Allows an application to call any phone number,
including emergency numbers, without going through the Dialer user
interface for the user to confirm the call being placed.
Not for use by third-party applications.

i'm late. You must request permission dynamically.
// Here, thisActivity is the current activity
if (ContextCompat.checkSelfPermission(thisActivity,
Manifest.permission.READ_CONTACTS)
!= PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(thisActivity,
Manifest.permission.READ_CONTACTS)) {
// Show an expanation to the user *asynchronously* -- don't block
// this thread waiting for the user's response! After the user
// sees the explanation, try again to request the permission.
} else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(thisActivity,
new String[]{Manifest.permission.READ_CONTACTS},
MY_PERMISSIONS_REQUEST_READ_CONTACTS);
// MY_PERMISSIONS_REQUEST_READ_CONTACTS is an
// app-defined int constant. The callback method gets the
// result of the request.
}
}
more details at https://developer.android.com/training/permissions/requesting.html

Please change call_phone to dial phone. As you need to dial
the number.
Intent callIntent=new Intent(Intent.ACTION_DIAL);
callIntent.setData(Uri.parse("tel:1234567890"));
startActivity(callIntent);

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

Move the attribute
android:name="com.android.app.MyApplication"
to the first application element in the manifest and delete the second application element.
Btw. is your MyApplication class really in the package com.android.app?
EDIT: you use a different package, so the line should be
android:name="com.example.multitabcheckboxselection.MyApplication"
EDIT2+3: you have put it as an activity now. remove the activity, the attribute must go into the application tag.

Normally one would do like this
class MyApplication extends Application {
#Override
public void onCreate() {
super.onCreate();
mInstance = this;
}
static public MyApplication getInstance() { return mInstance; }
static private MyApplication mInstance;
}
Then from elsewhere
MyApplication myApp = MyApplication.getInstance();

Change
mApplication = (MyApplication)getApplication();
To
mApplication = ((MyApplication) getApplicationContext());
And in Manifest.xml define android:name="MyApplication"
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme"
android:name="MyApplication" >
Edit
Remove this
<application
android:name="com.android.app.MyApplication"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name" >
</application>
Each application will have only one <application> Tag

Change to
mApplication = (MyApplication)getApplicationContext();
Edit:
Delete the second application tag and move this to the first
android:name="com.android.app.MyApplication"
Edit:
public class MyApplication extends Application {
private static MyApplication singleton;
public MyApplication getInstance(){
return singleton;
}
public void onCreate() {
super.onCreate();
singleton = this;
}
// other methods
}
Then in Activity
mApplication = MyApplication.getInstance();
Example:
public class Main extends Activity{
ArrayList<HashMap<String,String>> arraylist = new ArrayList<HashMap<String,String>>();
MyApplication mapp;
#Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);

mapp = MyApplication.getInstance();
TextView tv = (TextView) findViewById(R.id.textView1);
tv.setText("My String from Application class is"+mapp.hello);
for(int i=0;i<10;i++)
{
HashMap<String,String> map = new HashMap<String,String>();
map.put("key", "value"+i);
arraylist.add(map);
}
mapp.setArrayListMapData(arraylist);
Button b = (Button) findViewById(R.id.button1);
b.setOnClickListener(new OnClickListener()

#Override

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:

</manifest>
And here are the .java files of my .Splash activity and my .Menu activity:
Splash
package com.example.secondapp;
import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
public class Splash extends Activity {
MediaPlayer ourSong;
#Override
protected void onCreate(Bundle savedInstanceState) {
// 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(){
try{
sleep(5000);
} 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" >

RunTimeException when trying to implement GPS Locater

I am working on adding GPS location services to my app. However I get this error I just can't seem to fix. I have included all of my relevant coding. And if anybody has comments on any of my coding not related to the error I would appreciate them too.

Java is a programming language and computing platform first released by Sun Microsystems in 1995.

cannot be cast to android.app.activity - java

Change <activity android:name=".rss.RssService" /> to <service android:name=".rss.RssService" /> And if you want to start service use method startService(Intent); by startActivity(Intent);

You need to call a different method for services: Intent loader_rssnik = new Intent(this, RssService.class); startService(loader_rssfuji);
