[SOLVED] Activity ends on HOME button

Activity ends on HOME button

I have weird problem with HOME button. I have two activities A and B.

A always starts B...like this:

startActivityForResult(new Intent("com.test.B"), 0);

and listening for result for finishing the whole app...but that i think doesn't matter.

When I'm in B activity, and hit the HOME button...and on long press of HOME button get back. Activity A is shown instead of B...

Why is that happening? Any idea? Should I set something in Manifest? It looks to like activity B is finished...but i dont want that. I want B to be shown...

Here is some code from A activity:

// Start new activity
Intent intent = new Intent(getApplicationContext(),B.class);
startActivityForResult(intent, 0);

And here is some code from manifest:

<activity
        android:label="A"
        android:name=".A"
        android:screenOrientation="portrait" >
        <intent-filter >
            <action android:name="com.uno_manager.A" />

            <category android:name="android.intent.category.DEFAULT" />
        </intent-filter>
    </activity>
    <activity
        android:label="B"
        android:name=".B"
        android:noHistory="true"
        android:screenOrientation="portrait" >
        <intent-filter >
            <action android:name="com.uno_manager.B" />

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

I have activity one activity before those two...that represents splash screen.

In activity B I have overridden onRestoreInstance and onInstanceSave methods. And on some click I call setResult and finish() to exit the app. But I don't think that have anything to do with this.

I've tried to comment whole code from B activity. I've left only setContentView in onCreate method. And the same thing happened on HOME button.

Solution

In your manifest file add launchMode attributes to your activities. See this link for more information to reuse http://developer.android.com/guide/topics/manifest/activity-element.html#lmode

I think anything apart from standard would work for your requirement, but see the documentation for full information or experiment with them to find out the correct one
