ClassNotFound Exception while class is declared in Manifest

Question

I'm using the aFileChooser library, and every time I select to choose a file, I get a class not found error, even though I have added it to my build path and Manifest. Here's whats in mu Manifest:

    <activity
android:name="com.ipaulpro.afilechooser.FileChooserActivity"
android:icon="@drawable/ic_chooser"
android:enabled="@bool/use_activity"
android:exported="true"
android:label="@string/choose_file" >
<intent-filter>
    <action android:name="android.intent.action.GET_CONTENT" />

    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.OPENABLE" />

    <data android:mimeType="*/*" />
</intent-filter>
</activity>

And heres my logcat:

maybe [this](http://stackoverflow.com/questions/10866431/android-activity-classnotfoundexception-tried-everything) will help?. — Spurdow, Aug 14 '14 at 16:46
Thats originally how I had it set up, and tried adding it to my java build path. But I tried this again, and still had no luck. :( — dogger20011, Aug 14 '14 at 16:58
can u try the correct way again, and then clean your project — Spurdow, Aug 14 '14 at 17:00
[is this the one u tried?](http://developer.android.com/tools/projects/projects-eclipse.html#ReferencingLibraryProject) — Spurdow, Aug 14 '14 at 17:01
remove it from your build path, just do the correct-way of referencing libraries in android. — Spurdow, Aug 14 '14 at 17:02
I removed it from my build path, and I have referenced the library, and just tried cleaning the project afterwards. Still no luck — dogger20011, Aug 14 '14 at 17:16

Make sure you have correctly imported the library Then Make Sure your actual project is not selected as library

Check the Class name and file name Make sure your android manifest package name is correctly mentioned

or

NoNonsense-FilePicker

   <activity
        android:name="com.nononsenseapps.filepicker.FilePickerActivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait"
        android:theme="@style/FilePickerTheme">
        <intent-filter>
            <action android:name="android.intent.action.GET_CONTENT" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>

I've checked all that, still nothing. – dogger20011 Aug 14 '14 at 19:29 — dogger20011, Aug 14 '14 at 19:29
