Android application crashes upon opening

I'm developing an android application and as soon as the AVD opens and I unlock the device and click the menu, I get an "Application stops unexpectedly" error. The following is my logcat log.

Could you add com.compliment over here:

<activity android:name="com.compliment.ComplimentGenerator" android:label="ComplimentGenerator">

Edit: Change <activity android:name="ComplimentGenerator" android:label="ComplimentGenerator"> to <activity android:icon="@drawable/icon" android:label="ComplimentGenerator"> From the docs,

public class Application

Base class for those who need to maintain global application state. You can provide your own implementation by specifying its name in your AndroidManifest.xml's tag, which will cause that class to be instantiated for you when the process for your application/package is created.

There is normally no need to subclass Application. In most situation, static singletons can provide the same functionality in a more modular way. If your singleton needs a global context (for example to register broadcast receivers), the function to retrieve it can be given a Context which internally uses Context.getApplicationContext() when first constructing the singleton.

In other words, when you added android:name, the ComplimentGenerator class was being instantiated. However, ComplimentGenerator was not subclassing Application (which was required), which resulted in a ClassCastException.

    AndroidManifest.xml 
    <application android:name="ComplimentGenerator" android:icon="@drawable/icon">

 Just Rename Your
      android:name="ComplimentGenerator"  to   android:label="ComplimentGenerator"

I think the "android:name" attribute value is wrong! Use the following (starting with the "."):

<activity android:name=".ComplimentGenerator" android:label="ComplimentGenerator">

Thus, Android will know the starting activity is com.compliment.ComplimentGenerator

  • "com.compliment" comes from the "package" attribute value

  • ".ComplimentGenerator" comes from the "android:name" attribute value
