Unfortunately My app has stopped [Android Emulator]

Question

While I am adding an Action bar, emulator will be displayed "Unfortunately MainActivity has stopped", even no error and installed

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.example.trintwo"     
      android:versionCode="1"
      android:versionName="1.0">
<uses-sdk
        android:minSdkVersion = "7"
        android:targetSdkVersion = "18" />

    <application android:label="@string/app_name" android:icon="@drawable/ic_launcher">
        <activity android:name="MainActivity"
                  android:label="@string/app_name"
                  android:theme="@style/Theme.Holo.Light">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>

        <activity
                android:name = "com.example.trintwo.DisplayMessageActivity"
                android:label = "@string/title_activity_display_message"
                android:parentActivityName = "com.example.trintwo.MainActivity">
                <meta-data
                        android:name = "android.support.PARENT_ACTIVITY"
                        android:value = "com.example.trintwo.MainActivity" />
        </activity>
    </application>
</manifest>

This is my res/values/styles.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>

<!--
    Base application theme for API 14+. This theme completely replaces
    AppBaseTheme from BOTH res/values/styles.xml and
    res/values-v11/styles.xml on API 14+ devices.
-->
        <style name="AppBaseTheme" parent="android:Theme.Holo.Light"></style>
        <style name="CustomActionBarTheme"
                 parent="@android:style/Theme.Holo.Light.DarkActionBar">

        </style>

</resources>

debug successfully and installed successfully but emulator show this "Unfortunately MainActivity has stopped"

I am using terminal [not eclipse]

You seem to be missing the attribute from your manifest. This could be your problem. For more information, see here: http://developer.android.com/guide/topics/manifest/uses-sdk-element.html

That depends entirely on what version of Android you are compiling for. Please read the link I gave you, it will tell you exactly what you need to know. – Nathan Walters Jan 02 '14 at 14:14

Assuming you added the CustomActionBarTheme style to your styles.xml file (per your code sample) then there's nothing wrong with that markup.

Can you provide the markup that is using the CustomActionBarTheme style?

Also, if you remove that style altogether does the app run? Always a good idea to reverse changes until you get back to a working version then line-by-line add the potentially offending code back in.

Welcome to Stackoverflow!

Unfortunately MainActivity has stopped

There is only one reason for that. You got an EXCEPTION. You need to install logcat some how. It will tell you what it is.

Show us the log exception and we will help you.

I ran into the same problem while going through a tutorial.

What seemed to worked for me is cleaning my project in Eclipse and running my app on my device again.

Are you building the app for the correct API Level?

If your API level is below 11 you need to import android.support.v7.app.ActionBar

Otherwise import android.app.ActionBar

You can try and install Acra so that you get the logs leading up to the exception – Harshit Jain Jan 03 '14 at 09:18
