For main activity in your manifest you have to add this with category LAUNCHER
(First Activity on launch app):
<activity android:name=".MainActivity" android:label="YourAppName" android:theme="@style/AppTheme.NoActionBar" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter> </activity>
For other activity you have to change category to DEFAULT
:
<activity android:name=".OtherActivity" android:theme="@style/AppTheme.NoActionBar" > <intent-filter> <action android:name="package.OtherActivity" /> <category android:name="android.intent.category.DEFAULT" /> </intent-filter> </activity>
Check this Activity and this Start Another Activity
So your code is:
<?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.example.mrrobot.mycoolweather" > <uses-permission android:name="android.permission.INTERNET"/> <application android:allowBackup="true" android:icon="@mipmap/ic_launcher" android:label="@string/app_name" android:supportsRtl="true" android:theme="@style/AppTheme" > <activity android:name=".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> </application> </manifest>
