Answer 1

Exit your android studio IDE. Then locate the "caches" folder in .AndroidStudio3.2 folder.

Location

C:\Users\YOUR_USERNAME\.AndroidStudio3.2\system\caches

For example.

Let's assume say YOUR_USERNAME is called Admin.

C:\Users\Admin\.AndroidStudio3.2\system\caches

Delete the caches folder and start your android studio IDE.

Answer 2

In your manifest file there was wrong element name (Activity change to activity) declared

<Activity       android:name="com.example.mrrobot.mycoolweather.activity.ChooseAreaActivity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </Activity>

Change it to:

 <activity       android:name="com.example.mrrobot.mycoolweather.activity.ChooseAreaActivity"
        android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN"/>
            <category android:name="android.intent.category.LAUNCHER"/>
        </intent-filter>
    </activity>

I have tried solutions here and other questions

• clean & rebuild & invalidate and restart
• make sure that activity has LAUNCHER as category
• delete Android cache folder

at End, activity tag was has <activity android:name="com.exmaple.todo.MainActivity" /> when i changed it to <activity android:name=".MainActivity" /> app worked.

I hope it help you if other solution not work.

Answer 5

i had these issues with my project:

• Default activity not found

• xml intellisense was not working

• kotlin standard functions were not detecting

All my above issues were resolved by Deleting System cache of Android Studio 3.3 at the home path, and it's working nicely for me,, Steps:

1. exit Android Studio

2. Go to path > C:\Users\YOUR_WINDOW_USER_NAME.AndroidStudio3.3\system

3. Then you have a \caches folder, delete this caches folder

4. Now open Android Studio and load your project

Worked for me.. i wasted couple of hours resolving this issue and finally it got resolved in this way.

Answer 6

My main activity was not declared in Android Manifest File. That's the reason which came that error. This error come because of a declaration problem of Android Manifest file. Please check it. :D
