Startactivity Within A Subclass Of Application

I have a little Android application in which I specify my application directly and do some application-wide setup in the ApplicationSubclass' onCreate, but I am getting the followi

Solution 1:

Ah! I figured out what I did, it's quite simple! I was setting the FLAG_ACTIVITY_NEW_TASK on the wrong intent! Silly me, I missed that Intent.createChooser(...,...) will return a new Intent, so you must set the flag on the chooser Intent rather than on the ACTION_SEND Intent.

Not all that confusing when you think about it, and I can't believe I overlooked that!

So if anyone ever does what I did, here you go:

publicvoidsendNotificationEmail(String emailBody) {
        IntentemailIntent=newIntent(Intent.ACTION_SEND);
        emailIntent.setType("text/html");
        emailIntent.putExtra(Intent.EXTRA_EMAIL, notificationRecipients);
        emailIntent.putExtra(Intent.EXTRA_SUBJECT, "MyAppName Error");
        emailIntent.putExtra(Intent.EXTRA_TEXT, emailBody);
        IntentemailChooser= Intent.createChooser(emailIntent, "An error has occurred! Send an error report?");
        emailChooser.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
        try {
            startActivity(emailChooser);
        } catch (ActivityNotFoundException e) {
            // If there is nothing that can send a text/html MIME type
            e.printStackTrace();
        }
    }

Solution 2:

I have launch an activity(to relogin the user when loss the session) from my class which subclass from Application as follow:

publicbooleanrelogin(Activity act) {      
    Intentintent=newIntent(act,ActivityLogin.class);    
    intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);     
    intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
    startActivity(intent);              
    act.finish();// here i finish my current activity
}
