Question

I’m expecting quite a strange behavior in a tiny app I’m currently working on.

The app consists of two activities. From the first activity I’m launching the webbbrowser via an intent. When I press the back key in the browser it returns to the SECOND activity even if I manually closed the app previously before launching.

1) First Activity

final Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(mWebShopURL));
startActivity(intent);

First Activity launches second activity like this

Intent intent = new Intent(getApplicationContext(), SecondActivity.class);
Bundle b = new Bundle();
b.putString("product", mProduct);
intent.putExtras(b);
startActivity(intent);

2) Second Activity -> first activity

onBackPressed();

AndroidManifest

    <activity
        android:name=".FirstActivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
     <activity
        android:name=".SecondActivity"
        android:label="@string/app_name"
        android:screenOrientation="portrait" >
    </activity>

Answer 1

If you want the second activity to complete and go away when the user taps on the simple “back button” you refer to in your comment, then don’t call onBackPressed(). Please just call finish(). That will make the second activity go away and return the user to the first activity.

Your problem is that you’ve never removed the second activity from the stack, which is why returning from the browser shows that activity.
