I don't know how to figure out where an uncaught exception is coming from. I have looked through the stackoverflow posts and tried looking for several of the solutions. As far as I can tell, I have my activity, "Monitor", listed in my manifest and it is part of the package. But I get a null pointer exception when I start the "Monitor" activity. What should I be looking for to find this exception?

Provided that you have editTextCurTemp defined as TextView in your_layout_file.xml, you must call
setContentView(R.layout.your_layout_file)
BEFORE you do any findViewById(), otherwise you will get NPE.

Code:
public class MainActivity extends Activity implements
EventsListFragment.Callbacks {
private EventsListFragment mEventsListFragment;
#Override
protected void onCreate(Bundle savedInstanceState) {
getWindow().requestFeature(Window.FEATURE_INDETERMINATE_PROGRESS);
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mEventsListFragment = (EventsListFragment) getFragmentManager()
.findFragmentById(R.id.list_fragment);
}
}
I checked everything my package name, xmls but I don't why I am getting this one.
Check if EventsListFragment is public
in one of your layout files(activity_main) you are passing
com.google.android.apps.watchme.EventsListFragment as an address for your fragment
, check if the address for EventsListFragment is correct
Adding android-support-v4.jar solved my problem. Also, changed priority to top & checked it in project properties section.
I am using cordova 3.6 and android 4.4 and i used a simple example for opening a camera or choose picture from gallery but on every success callback for camera getting below error

I tried on different machine also but having same issue.
I have searched the internet for days and have found dozens of solutions none of which work. So I thought I'd post my situation:
I have installed eclipse and the 2.3.3 android SDK onto my laptop, put the code in for hello world (or hello android) and clicked run. The emulator starts but when the activity is run I get the message "SORRY! the application Hello Android (process com.example helloandroid) has stopped unexpectedly. Please try again"
package com.example.helloandroid;
import android.app.Activity;
import android.os.Bundle;
import android.widget.TextView;
public class HelloAndroid extends Activity {
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
TextView tv = new TextView(this);
tv.setText("Hello, Android");
setContentView(tv);
}
}
and this is log cat

It seems to be something wrong with the way your emulator is set up. Did you follow this tutorial especially the "Setting up the AVD" part?
I would start the install of the emulator all over again. Also you could send him a copy of your program and if he can successfully run your project in the emulator then you know you just need to get your emulator set up correctly.
try moving your setContentView() method above your textview initialization
Here's the error message I'm getting: E/AndroidRuntime(416): java.lang.RuntimeException: Unable to start activity ComponentInfo java.lang.IllegalArgumentException. I took out the app file name/package name, but everything else is there. The app is designed to target the Gingerbread, but has a minimum SDK level for the Froyo. I'm basically get an AVR message when I try and launch the app on the AVD. The source code is ~460 lines long, so I'm not sure where the error is (there are no syntax errors, so I'm not sure what I'm doing wrong). Here's the pastebin URL for the source code that I've put up: http://pastebin.com/EtUP2CAB. I've seen some stuff about DecimalFormatSymbols and the SensorSimulator, etc., but I'm still confused. Hence, I'd appreciate some help with locating the issue here causing this error.
EDIT: Here's the error log for the last run I did:

int randomIndex = random.nextInt(numberOfFlags);
numberOfFlags are not positive number, its 0 or less than 0, check numberOfFlags value by debugging.

Make sure to import the Fragment from the library. Fragment in later Android versions and Fragment in the compatibility library have different packages!
