我该如何修复'android.content.ActivityNotFoundException'？

Question

The problem is that I'm able to start my app " tk.buntowaf.docs " but when I try to use the app it crashs.

Error

I debugged the app with the adb logcat *:E command and I got this error output:

AndroidRuntime: Caused by: android.content.ActivityNotFoundException: Unable to find explicit activity class {tk.buntowaf.docs.app/tk.buntowaf.docs.DocsWebViewActivity}; have you declared this activity in your AndroidManifest.xml?

Here is the complete logcat for this app:

Answer 1

your last activity in manifest has problem

set that like this and i think it solve your problem

instead of these

 <activity
    android:name="tk.buntowaf.docs.DocsWebViewActivity"
    android:configChanges="keyboardHidden|orientation|screenSize"
    android:screenOrientation="sensor"
    android:theme="@style/FinestWebViewTheme.Light"/>

<activity android:name="tk.buntowaf.docs.app.WebViewActivity"/>

just past these

<activity
    android:name="tk.buntowaf.docs.DocsWebViewActivity"
    android:configChanges="keyboardHidden|orientation|screenSize"
    android:screenOrientation="sensor"
    android:theme="@style/FinestWebViewTheme.Light">

  <intent-filter>
    <action android:name="android.intent.action.MAIN"/>
  </intent-filter>

</activity>

you entered the android:name .... twice
and also i think its necessary to have intent-filter for activity
