If I have a button that starts an activity, and the activity sometimes takes a second or two to throw up its own view, how can I most simply and reliably protect against the button being clicked multiple times and kicking off multiple (identical) activities?

I added an intent filter to one of my activities, so that when a user clicks a URL like "www.mysite.com", and if my app is installed, my registered activity can be launched. It works well.
I see that this creates a new instance of my registered activity though, every time a link is clicked. Is there any way to prevent multiple instances from being created - just recycle an existing instance if one already exists?
I am trying to launch an activity from another activity .. Within the com.android.SingleLauncher..
I have activity launch code as ..

I have set the android:multiprocess="true" in the AndroidManifest.xml of TargetSL I don't seem to see the multiple instances of TargetSL, which i am expecting ..
All i see is 2 process, where i was hoping to see an instance of TargetSL, for each launch that was invoked by the singleLauncher!
I am developing an application in which the user require to register first and than got the user page. For that i have made layout and the layout consist many fields, so, i have made part of layout and also made the separate activity for the each layout. The layout like address, phone, etc... After that i have wrote the code for calling an activity and it works fine. It means when i press the "Next" button the another page will come and it will also consist some textview ,edittext and previous and next button. Actually, i want something different like -- When the user fill the first form and he will proceed to next, the content written by the user should not gone when the user press "Next" button. The content should be there which was written by user. And same way i have have 6 pages like that way to complete the registration process. So, have you any idea to solve above problem? I really need your help because right now i stuck at this point. So, please any body help me out of this problem. I would appreciate your help. I am waiting for your reply.
View 15 Replies View RelatedIn my current application design, I have an activity class application.java (which starts on launching the application), and it does not have a layout(UI screen). I call another class called servicebind.java from the onCreate method of my 1st class. here I bind to the local server (bindServer()). i call back the application class through an intent. Once I am back to my application class, I call my activity class called welcome.java which has a layout/UI. When I run this application, I am able to see the welcome screen. But the problem is, when I click on the back button, I get a black screen with just the title on top. I have to hit back button 3 times to exit the application.
The reason I see from the logs is that, the 1st 2 activity classes (application.java and services.java) does not get destroyed unless I hit the back button. So the 1st time I hit back button, the welcome activity gets destroyed. the next back button destroys the servicebind class and final back destroys the application class. Is the reason because these classes dont have a UI to display in the onCreate method. I do not want to change my design where I bind the service in the servicebind class and call the welcome activity in the application class.
I'm working on an app that launches the browser activity to perform a Twitter OAuth authorization. This process uses a callback url which will re-launch the activity that started the browser activity in the first place.My problem is that the browser pages remain in the history stack and when the user then clicks back from the preferences activity that launched the browser in the first place, they don't go back to the app's main activity, but instead are brought back to the browser. I've tried adding flags to the launching intent to prevent history and reset on clear, but it doesn't seem to work when running on my phone, only on the emulators.

View 1 Replies View RelatedI have an activity which overrides the onKeyDown method. The documentation states the following about onKeyDown: "Called when a key was pressed down and not handled by any of the views inside of the activity." The problem I have is that this method is being called even when the views inside the activity handle it. I have a button implementing a longPress listener. What I see on debugger when long clicking on the button with the center key is that first onKeyDown from the activity is called then the longPress listener from the button gets triggered. Even for Textviews, when long clicking on it with the center select, the activity onKeyDown gets triggered before the TextView processes the longclick (and shows the Input Method context menu).
View 5 Replies View RelatedI understand that trying to capture home button clicks is a hack, but I need to atleast close my current activity when the user clicks on home button. 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 7 Replies View RelatedI have Two activities One splash screen, Player screen. When user clicks on my app icon first splash screen is displayed and then player screen When player activity is running, if user returns to the home screen and then again clicks on app icon, the application is starting from the splash screen again.can any one please help me out how to do any one of below
1) I need to close current running activity and reload application.or
2) I need to resume to the player screen directly.Please give me an example or reference to follow, Im beginner in android programing.
My initial activity is basically a splash screen while preforming initialization and login in to network server. To save memory I want to finish() the splash activity once it starts the main menu activity. I still want the remote service to operate. Testing shows it does. But am I going to get into trouble doing this? I know I can restart the remote from the main menu activity but I am trying to save overhead by not starting it twice. The remote service is required by the splash activity.
View 1 Replies View RelatedI have a service that listens to a socket. When receiving certain input it is to create an activity. When receiving other input, it is to kill this activity. I have struggled for a while to make the service communicate with the activity through AIDL (http://developer.android.com/guide/developing/tools/aidl.html), but this seems to not be effective. I think AIDL is only effective when the process that is to be talked to is a service, not when it is an activity? I would love some directions or suggestions on how to solve my problem.
View 1 Replies View RelatedI would need to know when one activity starts or get's focus. I need this notification for any activity regardless of his type, name or whatever - not searching for one specific activity. Checked the ActivityMonitor and the Intent and I haven't found a generic intent for this purpose. Or I hadn't understood well the descriptions from the Intent ACTION_xxxxx.

View 4 Replies View RelatedThere are an EditText and a TextView in my Activity. I want to set focus on the TextView when the Activity starts. I used the following code:
TextView myTextView = (TextView) findViewById(R.id.my_text_vew);
myTextView.setFocusable(true);
myTextView.setOnClickListener(this);
myTextView.requestFocus();
But the code doesn't work. The EditText always receives focus when the activity starts.
When you receive clicks and long clicks, how do you get the x and y coordinates that were clicked?

View 2 Replies View RelatedI have an activity which loads a TableLayout. This is made up of TextView and EditView fields. When I run my app within the emulator the layout appears correctly (WITHOUT the soft keyboard appearing). When I run the app from a device (HTC Evo) and enter the activity the soft keyboard ALWAYS appears. I tried doing an OnFocusChange() for the first field in the layout and then doing:
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE); imm.hideSoftInputFromWindow(tvIndications.getWindowToken(), 0);
It doesn't work. The soft keyboard always appears.
I have 2 activities, A and B. When A starts, it checks for a condition and if true, it calls startActivityForResult() to start B. B only takes text input so it makes sense for the soft keyboard to automatically pop up when B start. When the activity starts, the EditText already has focus and it ready for input. The problem is that the keyboard never shows up, even with windowSoftInputMode="stateAlwaysVisible" set in the manifest under the <activity> tag for B. I also tried with the value set to stateVisible. Since it doesn't show up automatically, I have to tap the EditText to make it show.
View 2 Replies View RelatedI have added android:windowSoftInputMode="stateAlwaysVisible" to my Activity in AndroidManifest.xml and here's my layout:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical" android:layout_width="fill_parent"
android:layout_height="fill_parent">
<EditText android:id="@+id/EditText01" android:layout_width="wrap_content"
android:layout_height="wrap_content"></EditText>
<EditText android:id="@+id/EditText02" android:layout_width="wrap_content"
android:layout_height="wrap_content"></EditText>
<Button android:id="@+id/Button01" android:layout_width="wrap_content"
android:layout_height="wrap_content" android:text="Send"></Button>
</LinearLayout>
When the Activity starts, the EditText is focused, but soft keyboard isn't displayed. If I click on the EditText, then I see the soft keyboard. Do I need to set aditional parameters to display soft keyboard when my Activity starts?
I open an Activity which has a number of elements... some TextViews, some Buttons, and an EditText. For some reason, when the activity starts, the EditText is focused by default, which causes the keypad to appear hiding the screen. I only want this EditText to be in focus if the user clicks into it. How can I ensure that this View isn't in focus when the activity starts? I've tried calling requestFocus() on one of the buttons, but it hasn't changed anything. Ideally, I don't want anything in focus at all.
View 7 Replies View RelatedAre there design guidelines to help decide if an application with multiple views should be designed with multiple activities or just one activity and control the back button itself.
I've tried both. My most complex applications using one activity per screen. However, now that I'm successfully written an app with just one activity and handling the back button myself, I don't see any compelling reason to use multiple activities. The one activity application is much simpler and more straightforward.
What advantages of multiple activities am I missing?
I just created a simple application, that starts the Dial Activity and place a call. I did not provide any permission in the manifest file to start a call, but still the call activity starts. I also checked the AndroidManifest.xml file, there is no permission added, still the activity starts.
View 6 Replies View RelatedI have a widget that is supposed to start and stop a service (start it when it's not running, stop it when it is). This is working fine, however, each time the service is started, my app's main activity is also launched, which I don't want from the app's manifest, it works as I want it to (without launching the main-activity, just the service), but then I obviously don't have a main activity anymore.This is how I start the service (I would assume this is the normal way, and I can't see any reference to what might cause the MAIN intent to fire).

View 3 Replies View RelatedI have been in problem of the Activity life-cycle. All though i read lots of docs on it put on getting clear picture on it. I have Activity A. In that activity I have menu options. If we click any option it opens the respective activity like if i click on 2nd button it opens Activity B Now again Activity B has same options into it. When user clicks on 1st button then i need to go back to activity A. So using this. Intent intent = new Intent().setClass(context, Articles.class); startActivity(intent); So always it starts new instance of activity and fetch data from DB. I want something like Activity A can be resumed back as it was.
View 6 Replies View RelatedI have an activity that is showing a video and when the user clicks a button, a new activity is launched. When the video activity stops, I pause the video view. When the video activity starts up again, I try to resume the video view videoView.start(), however, the video starts over from the beginning. I'm thinking that the buffer must be lost somewhere, so I now try to capture the current position via videoView.getCurrentPosition(), however, this is always returning 0.
Anybody know how to resume video playback when an activity starts up again?
I have an application, which (for the sake of simplicity) has two types of activities - Overview and DetailView. The Overview activity shows a list of steps and allows the user to start a DetailView activity corresponding to the step chosen.
In the DetailView activity, the user can start another Overview, which shows different steps than the ones in the parent of the current DetailView.
In the Overview, DetailView is started by using startActivityForResult (). In the DetailView, when the user decides to start a second Overview, I call setResult () and finish () and then start the new Overview. In this scenario, onActivityResult () and finishFromChild () do not fire. Instead, they fire when the parent finishes (?).
Code from Overview:

Code from DetailView:
