I declare both of my activity class in AndroidManifest.xml file them when I run my application it stop unfortunately with this error message:-
android.content.ActivityNotFoundException: Unable to find explicit activity class {com.androidtutorialpoint.androidobservablescrollview/com.androidtutorialpoint.androidobservablescrollview.ParallaxToolbarScrollViewActivity}; have you declared this activity in your AndroidManifest.xml?
This is my manifest file:-
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="in.doctormobileapps.androidobservablescrollview">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:label="@string/app_name"
>
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity
android:name=".ParallaxToolbarScrollViewActivity"
android:label="@string/title_activity_parallaxtoolbarscrollview"
android:theme="@style/AppTheme.Toolbar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="com.androidtutorialpoint.androidobservablescrollview" />
</intent-filter>
</activity>
</application>
</manifest>
My Activity class names are:-
You placed it in the wrong location it should be inside the application tag. All your <activity... />
tags should be placed under the <application.. />
tag.
Hope this helps!
Clean your build and rebuild the project. If you are using instance run android studio feature then disable this for avoid this problem
Remove
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="com.androidtutorialpoint.androidobservablescrollview" />
</intent-filter>
otherwise change your package name insted of
com.androidtutorialpoint.androidobservablescrollview
Remove intent-filter tag from your second activity.
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="in.doctormobileapps.androidobservablescrollview">
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme">
<activity
android:name=".MainActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN"/>
<category android:name="android.intent.category.LAUNCHER"/>
</intent-filter>
</activity>
<activity
android:name=".ParallaxToolbarScrollViewActivity"
android:label="@string/title_activity_parallaxtoolbarscrollview"
android:theme="@style/AppTheme.Toolbar">
</activity>
</application>
</manifest>
Put intent filter to single activity which you want to start first. If launching activity is MainActivity, then remove intent filter from ParallaxToolbarScrollViewActivity. Or recheck the category line **
"com.androidtutorialpoint.androidobservablescrollview"
**
<activity
android:name=".ParallaxToolbarScrollViewActivity"
android:label="@string/title_activity_parallaxtoolbarscrollview"
android:theme="@style/AppTheme.Toolbar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="com.androidtutorialpoint.androidobservablescrollview" />
</intent-filter>
</activity>
