Change application's starting activity

Question

I have created the meat and guts of my application but I want to add a different activity that will be the starting point (sort of a log-in screen).

Couple questions:

• 1 I have a fairly decent handle on how to switch between activities (based on this article: http://www.linux-mag.com/id/7498) but I'm not sure how to go about creating a new one (with eclipse).

• 2 Once I have a new activity created, how can I set it as the default activity of my application? I presume I could just change the name of the classes...but is there a more elegant way to handle that (maybe within the AndroidManifest.xml)?

Answer 1

You add this you want to launch activity android:exported="true" in manifest file like

 <activity
      android:name=".activities.activity.MainActivity"
      android:windowSoftInputMode="adjustPan"
      android:exported="true"/>
  <activity

Open java file of this activity and right click then click on Run 'main Activity'

                                   OR

Oprn java file of this acivity and press Ctrl+Shift+F10

If you are using Android Studio and you might have previously selected another Activity to launch.

Click on Run > Edit configuration and then make sure that Launch default Activity is selected.

Answer 3

Follow to below instructions:

1:) Open your AndroidManifest.xml file.

2:) Go to the activity code which you want to make your main activity like below.

such as i want to make SplashScreen as main activity

<activity
    android:name=".SplashScreen"
    android:screenOrientation="sensorPortrait"
    android:label="City Retails">
</activity>

3:) Now copy the below code in between activity tags same as:

<activity
    android:name=".SplashScreen"
    android:screenOrientation="sensorPortrait"
    android:label="City Retails">
    <intent-filter>
        <action android:name="android.intent.action.MAIN" />
        <category android:name="android.intent.category.LAUNCHER" />
    </intent-filter>
</activity>

and also check that newly added lines are not attached with other activity tags.

Just go to your AndroidManifest.xml file and add like below

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

then save and run your android project.

 <application
    android:icon="@drawable/YOUR_ICON"    <!-- THIS ICON(IMAGE) WILL BE SHOWN IN YOUR APPS -->
    android:label="MY APP NAME " >    <!-- HERE LABEL(APP NAME) -->
    <activity
        android:name=".application's starting activity"  <!-- (.)dot means current dir, if your activity is in another package then give full package name ex: com.xxx.Activity  -->
        android:label="LABEL FOR ACTIVITY "
        android:screenOrientation="portrait" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>

It's simple. Do this, in your Manifest file.

<activity
    android:name="Your app name"
    android:label="@string/app_name">
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.HOME" />
            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
</activity>
