I managed to create a secondary Activity, but now I wonder how I can close it again.
public void button_onClick(View v){
finish();
}
works when I'm dealing with just one Activity at a time, but how do I let the secondary Activity close the entire application?

What's the best way to do this (bearing in mind cursor lifecycle). I don't care if the the system kills and restarts the secondary activity since in that case the stepping through entries functionality could be temporarily automatically disabled.

View 10 Replies View RelatedI have an activity which pops up a Dialog box, to get some text input from the user. The problem arises when you switch orientation. The Dialog disappears, so I have added code to set and check flags in the savedInstanceState, meaning that the Dialog is displayed again in these circumstances.I know when the window is going to be closed, but can't find a way of closing it manually. I open it with alert.show();but there doesn't seem to be any corresponding alert.destroy() method or similar.Any ideas how I can manually close the dialog box without user input?
View 3 Replies View RelatedI have three activity now, a, b and c, a is start point of activity lifecycle, and can go to b or c, and then assume go to b from a and close a, and then go to c from b but will not close b, and this time, I want to check whether b is start(create) or not,
if b start, I want to close b and then go to a, if b doesn't start(possible will go to c from a doesn't via b), it will also go to a but do nothing for b
how can I do for that?
I have a app,the structure composed three .java, 1.java,2.java,3.java

I have an EditText field and I want to pop up a new window/activity whenever a user touches/clicks the field. The new window has some widgets and of course Apply and Cancel buttons. Here is the code how I intercept the onTouch event.
EditText ctlMaskEt = (EditText)findViewById(R.id.mask_field); ctlMaskEt.setOnTouchListener(new OnTouchListener() { public boolean onTouch (View v, MotionEvent event) { popMaskEditor(); return true; } });
Everythings work fine until I click the Apply and Cancel buttons. The API finish() won't close the new window unless I click the same button one more time. Calling popMaskEditor() from a button's OnClick event handler doesn't have this problem.

View 2 Replies View RelatedI started to develope an application. When I wanted to close the application I clicked on the home screen, but the app is still playing in the background. Than I tried to click on the "back" key, but nothing happend, so I've created a key event listener for the 'back" key, and inside that method I wrote finish(); Now my app is closing but I think it's still running in the background, because when I go to "manage applications" I can still see it in the "running" tab, and if I press it, I see I can click on the "force close" to actually close the app. What do I need to do in order to really close the app without leaving it open (one way or another)?

View 2 Replies View RelatedMy app keeps force closing before it starts, eclipse returns no errors in my code and my xml is good.
package com.mhe.test.scan;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class main extends Activity {
/** Called when the activity is first created. */
@Override public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button myScanButton = (Button) findViewById(R.id.myScanButton); myScanButton.setOnClickListener(new Button.OnClickListener() {
public void onClick(View v) {
Intent intent = new Intent("com.google.zxing.client.android.SCAN");
intent.putExtra("SCAN_MODE", "PRODUCT_MODE");
startActivityForResult(intent, 0);
} } );
} EditText totalbox = (EditText) findViewById(R.id.totalbox);
public void onActivityResult(int requestCode, int resultCode, Intent intent) {
if (requestCode == 0) { if (resultCode == RESULT_OK) {
String contents = intent.getStringExtra("SCAN_RESULT");
// Handle successful scan totalbox.setText(contents)
} else if (resultCode == RESULT_CANCELED) {
// Handle cancel totalbox.setText("@string/bummer");

Essentially it is supposed to call zxing Barcode Scanner to scan a barcode on a button click and return the result into an EditText field.
Just wondering is it necessary to close cursor when an activity is stopped or pause?

View 1 Replies View RelatedI'm writing a graphic design application for Android where the user can add several images to a document, where each image is stored as a Bitmap object. Each bitmap has roughly a dimension of 800x400 pixels and uses ARGB8888 pixel format (i.e. ~1.5Mb each).
I'm aware that most of the first generation Android devices have a 16Mb heap limit and this limit is 24Mb and larger for newer phones. I'm also aware that bitmap memory is allocated externally, but I'm confused and what the implications of this is.
My question is: How can I tell at runtime when adding a new Bitmap will get me too close to the memory limit?
Before someone suggests "don't use that much memory", I know that one option I have is to limit how many Bitmaps the user can create such that I know this limit is safe for the most basic Android phones. However, I'd like for phones with a bigger memory limit to support more bitmaps and/or bigger bitmaps.
I know to check for OutOfMemory exceptions when allocating bitmaps. However, there will be some situations where I've only got just enough memory left to allocate one more bitmap. After this point, the whole application will be unstable because even allocating small things like strings could cause an OutOfMemory exception. This is something I want to avoid.
I'm not sure how to define "too close to the memory limit", but I suspect something like "don't allocate more than half of your available memory to bitmaps" would work OK as my other data structures I store in memory are small in comparison.
Is there any way for an activity to register for being notified if a wait/force close dialog is shown or alternatively if the user selects force close, a way to detect that in ondestroy()?

Is there anyway I can tell the system to close this activity is the user clicks on home button? If so how can I do that? I need to do it as I am listening for location updates and I want to stop the updates and also need to trash any location that was available to me previously. I need to do this just in case any user while in that activity clicks on home button and changes the location settings.

View 1 Replies View RelatedI have a toolbar view set for most of my activities.
The toolbar has several buttons which all trigger certain intents. Now, the problem is: how can I close current activity before starting another one ?
Problem 1) Activity cones For instance one of the buttons ('A') starts activity A. Activity A also has toolbar. If you press on the 'A' button, a new A activity will be started. I suppose I can look at Activity.getInstanceCount(), right ?
Problem 2) Unnecessary activities The activity X is not needed any more if the opts for A. I just want A then. How can I remove X from toolbar which only has access to context ?
I, of course could find toolbar view inside activity X and override the onClicks, but in general this would mean doing so for all my activities !? Am I on the right track ?
Is there a way to notify an activity/service of a force-close request right before it gets killed?

How do I close a whole hierarchy of activities and show a new activity not present in the current task?
Context
Consider a FTP browser that resumes the previous session on launch. Each folder is displayed in its own activity. When I click on a folder, a new activity is started for the folder. If I press the back button, the app returns to the previous activity, which corresponds to the the parent folder.
I can logoff from the menu at any time. Logging off should bring me to the login activity (not present the current task when the app has resumed the session), and close all the other activities. How can I do this?
From what I've read, if the activity were in the current task I could use FLAG_ACTIVITY_CLEAR_TOP in the intent, but this is not my case.
This just occurred to me today and it would be really nice. I've bought a few apps I no longer want/need and would be willing to sell them to someone else at a discount to recoup some of my loss.Any thoughts on this? I think it would need to be an update to the android market to have an option to 'transfer' to another user so updates for the app would show up in the market. You could keep the developers happy by giving them an option to make their apps eligible for this or not.I suppose this would only be feasible for apps that are also the type that are private and can't be backed up to the SD card with something like Astro File Manager.

View 4 Replies View RelatedSo I was poking around the internet and saw the new Lenovo LT 1421 USB portable monitor. URL>....
I found myself intrigued by it and was thinking about getting one as I travel a lot for business and find that not having that second monitor like I have on my desktop at the office is a major point of frustration.
I was looking at it and thinking to myself "man that looks a lot like a tablet." I got to searching the internet for ways to turn an android tablet into a secondary monitor and found Apps like iDisplay and AirDisplay (iPad only) and Screen Slider that work over wifi but those methods all seem to be really slow and laggy. It would be better than what I have for sure but given that I'm often on hotel Wifi and it requires a network connection between devices that leaves me open to some vulnerabilities I would assume.
