Solution 2

Look at this line:

3-12 12:31:03.465: E/AndroidRuntime(4997): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.example.softwaresearchapp/com.example.softwaresearchapp.MainActivity}: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.softwaresearchapp/com.example.softwaresearchapp.SoftwareSearchActivity}; have you declared this activity in your AndroidManifest.xml?

Specifically: Unable to find explicit activity class {com.example.softwaresearchapp/com.example.softwaresearchapp.SoftwareSearchActivity}; have you declared this activity in your AndroidManifest.xml?

Well, have you?

Each activity in your app must be declared in the manifest file. I imagine the minimum information you would want to provide would be the name and label e.g.

<activity
        android:name=".SoftwareSearchActivity"
        android:label="@string/title_activity_software_search"
 />

OTHER TIPS

your logcat clearly said

 Caused by: android.content.ActivityNotFoundException: Unable to find explicit activity class {com.example.softwaresearchapp/com.example.softwaresearchapp.SoftwareSearchActivity}; have you declared this activity in your AndroidManifest.xml?

Add SoftwareSearchActivity into manifest.xml like

     <activity
        android:name="com.example.softwaresearchapp.SoftwareSearchActivity"
        android:configChanges="keyboardHidden|orientation"
        android:label="SoftwareSearch"
       />

You are getting ActivityNotFoundException. Please check for Activity entry for com.example.softwaresearchapp.SoftwareSearchActivity in manifest file.
