I am starting to learn to develop app´s to Android systems.
I was tryng to execute a simple Hello World app on Netbeans, but I got this "Error - Unfortunately, Main Activity has stopped."... I don´t have a clue why...
The code is as follows...
mainactivity.java
import android.app.Activity;
import android.app.Activity;
import android.app.Activity;
import android.app.Activity;
import android.os.Bundle;
import br.com.bssotware.teste.R;
public class MainActivity extends Activity
{
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
}
}
And the main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Hello World, MainActivity"
/>
</LinearLayout>
When I execute it, I´ve got this log errors:

You full activity name (package + class) is not the same in manifest and code. There's pack.MainActivity declared in manifest but it is not found in code.
I have been trying to extend FragmentActivity. The same app works if I extend the MainActivity class to Activity and import necessary packages for a normal Activity.
The basic need is that i cannot access the map in a normal activity. It needs to extend FragmentActivity to run the following line.
googleMap= ((SupportMapFragment)getSupportFragmentManager().findFragmentById(R.id.map)).getMap();
Here is the Java code
package com.dacoders.locationtodo;
import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;
public class MainActivity extends FragmentActivity {
#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;
}
}
Here is the layout XML
<fragment xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:name="com.google.android.gms.maps.MapFragment"/>

Here is the layout XML
<fragment
I'm not sure if you can have a fragment as the root of your layout as fragments are supposed to be pieces that are put in another layout and exchanged.
Have you tried putting your fragment in a FrameLayout and see if it still crashes?
Your min sdk is 11. I guess you can make it 12 and use MapFragment.
To know why check the link http://developer.android.com/about/dashboards/index.html.
In that case (minsdk is 12 or above) you can extend Activity
GoogleMap mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map))
.getMap();
Also import
import com.google.android.gms.maps.MapFragment;
Or
You should use Support Fragment.
<fragment
class="com.google.android.gms.maps.SupportMapFragment"
android:id="#+id/map"
android:layout_width="match_parent"
android:layout_height="match_parent"/>
Your activity must extend FragmentActivity
SupportMapFragment fm = (SupportMapFragment) getSupportFragmentManager().findFragmentById(R.id.map);
GoogleMap mMap = fm.getMap();
Make sure you have added support library
Also make sure you imported the below
import android.support.v4.app.FragmentActivity;
import com.google.android.gms.maps.SupportMapFragment;
my android app was running fine until I added some classes and edited the manifest file.
Now, when I try to run or debug the app on my android emulator with android 2.2, the app crashes and I get a ClassNotFoundException as follows:

I guess it's something wrong with my project configuration. Here is my manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="de.bastian.gpstracker"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="10" />
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme"
android:name="de.bastian.gpstracker" >
<activity
android:name="de.bastian.gpstracker.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
To be honest, I do not remember the last changes I made to this file, but, to me, everything seems to be fine here.
While searching for a sultion, I also came along the link Android Activity ClassNotFoundException - tried everything, which describes the same problem, but has a solution no applicable to my case as I am only working with a single project.
In the error log above, I noticed that the file name of the apk created ends on a '-1'. Maybe that's an error, maybe that's simply how eclipse/adt handles things. Also, I noticed that, when I try to run/debug the project, multiple class files with names MainActivity.class, MainActivity$1.class, MainActivity$2.class are created, although I only have a single MainActivity.java file (and no MainActivity$2.file or anything like that).
It would be great if someone had an idea of what's going wrong here.
You are setting the application node to reference a nonexistent class
de.bastian.gpstracker
Refers to the package name, no class whatsoever. Since gpstracker is the last thing in that string, the class loader assumes that gpstracker is a class, tries to load it and fails.
So write the name of the Application class (which extends Application).
Eg
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme"
android:name="de.bastian.gpstracker.MyApplicationClass" >
If you don't have a class that extends Application, then take out the android:name attribute for this node so it looks just like:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
Change your application tag in manifest to this:
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="de.bastian.gpstracker.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
Remove the name attribute from the application tag.
It, misleadingly, does not have anything to do with the name of your app and is actually the name of an extra class to load before loading your application. That's why you are getting the ClassNotFoundException. Remove it and it should work:

it says that class is not there, but it IS there. I tried to configure things in my project's build path, but not too sure what to tweak there.
And here is how I start my Manifest file:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="business.premium"
android:versionCode="1"
android:versionName="1.0" >
<supports-screens android:largeScreens="true" android:normalScreens="true" android:smallScreens="true"/>
<uses-sdk android:minSdkVersion="4" android:targetSdkVersion="15"/>
<uses-permission android:name="android.permission.INTERNET" />
<application
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/CustomTheme"
android:name="MyApplication"
android:debuggable="true">
<activity
android:name=".Problemio"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
Any thoughts on how to solve this, or what to look into? Thanks!
Its because you specified the "android:name" attribute in the application node in the manifest file.
Do not use the android:name attribute!
It, misleadingly, does not have anything to do with the name of your app and is actually the name of an extra class to load before loading your application. That's why you are getting the ClassNotFoundException.
Remove it and it should work:
<application
android:icon="#drawable/icon"
android:label="#string/app_name"
android:description="#string/help_text" >
