             Summary: Add code fix to broken activity sequence
                 Key: CB-3949
                 URL: https://issues.apache.org/jira/browse/CB-3949
             Project: Apache Cordova
          Issue Type: Bug
          Components: Android
    Affects Versions: 2.8.0, 2.7.0
            Reporter: Kuan Yi Ming
            Assignee: Joe Bowser


If installing an app via sideloading on Android, going through several pages, then pressing Home and later resuming the app later may break the page sequence.

Tested on a Galaxy Nexus, Android 4.2

Steps to replicate:
# Copy APK over to phone storage and install it.
# Click 'Open' when the package installer has installed the app, instead of clicking 'Done'
# Open several pages (e.g. index.html -> page1.html -> page2.html)
# Press Home to pause the app, then reopen the app from the app drawer.
# The app will relaunch as if it were a new activity instance (showing splashscreen again if configured, and adds index.html to the page sequence)

These steps can't be replicated if the app was originally opened in the app drawer, a shortcut in the homescreen, or launched via Eclipse's Run button. 

This probably is an Android issue and not PhoneGap, but appears to be fixed by adding code before calling super.loadUrl() in the activity to check for Intent anomalies:

{code:java}
        Intent intent = getIntent();
        String intentAction = intent.getAction();
        if (!isTaskRoot() && intent.hasCategory(Intent.CATEGORY_LAUNCHER) && intentAction != null) {
        	if(intentAction.equals(Intent.ACTION_MAIN)) {
	            Log.d("Cordova", "This activity should be the root. Finish it first before launching.");
	            finish();
	            return;
        	}
        }
{code}
