New to android so please bare with me here
Is it possible to detect all touch events in an Activity and capture it and then in return pass that pass event to another View. For example:
Button 1 and Button 2. When Button 1 is pressed I want to capture that touch/click event and automatically pass that touch event to Button 2, basically with one touch/press you get the click generated and that same click is passed on to the second button automatically.
I would like to handle pinch events in my Android application to zoom in and out.
I believe Android 2.0 has multi-touch functionality, and heard that Android 1.6 might or might not support it depending of the device.
What's the best way to detect pinch events, while degrading gracefully for devices that don't support it? I'm targeting Android 1.5 upwards.
I want to create an app or background service that just listens for the launch of a 'default' app, say Contacts or the built-in Gmail app. If the contact app is clicked, I want to transfer control to my app temporarily (e.g. present a Yes/No popup to the user or increment an internal counter of my app ) and then redirect the user back to the app that was clicked. I want to do this only for a couple of 'well-known' built-in default apps, not any third party apps..

It'd be cool if we could all get together -- for a beer, to wait in line together, check out the phones, to upload pics, to support AndroidForums.com and Phandroid.
What does everyone think about that? Let's make this thing concrete.

I would like to be able to detect when a user types a key in the Search Dialog. I plan on using this to hook in to custom suggestion functionality.
Note: The built-in Search Manager custom suggestions functionality won't work for me because I need to customize the layout of the suggestions.
I'm working on the upgrade process for an Android app and am having a hard time ensuring a graceful shutdown of the old version. Can someone explain how the old version of the app is killed and if there is anything we can do to hook into the process? In more detail:
We notice that a new version of our app is available and launch a new activity with Intent.ACTION_VIEW pointing to the new apk file (or to the marketplace, once our app is there). However, the user has 2 chances to abort the install (once at the warning about reinstalling the app, and the second when warned about the permissions our app needs). My understanding is that I can't use startActivityForResult() with ACTION_VIEW, so I can't find out if the Action is aborted or not. So we can't tell if/when the install has been started.
We'd like to ensure that our app shuts down cleanly since we use a lot of native code and threads. We could kill our app proactively, as soon as we launch the ACTION_VIEW activity, but then we're left in a bad state if the user aborts. We could wait for the installer to remove our files, prior to installing the new version, but that's a hack. Is there any clean way to do this? Our main window is never seeing an onDestroy(), btw.
I've looked in Appbrain and all I see are apps for 1 touch or 2 touch reboot. What I'd like is to find an app that will shut my phone off. Period. Plain and simple. Anyone know of this? If not, will you make it for me? A friend of mine told me how easy app inventor is. When I get my google invitation, that will be my first app.

This occurred concurrently with installing a battery charge indicator app. I uninstalled the app and now the problem has disappeared. My unabated installation of apps has now stopped. I am now convinced that the app world is full of bugs and crap. I bet half the problems that folks have are due to unvetted apps being used. I am now trying to figure out how to properly screen them before I install them and inherit a fatal bug in the process.

Anyone know what I can use that isn't my default so I can retain my personal schedule and, if I want to do extra, can see this app's contents?

Whenever I edit and mark some events via the calendar app, it is stored in the database but if I edit the calendar.db from some outside source the changes made are not reflected in the calendar app. So my question is:
Does the calendar app maintain a cache or some other form of database? If yes then where and how?

How do you programmatically detect the application heap size available to an Android app?
I heard there's a function that does this in later versions of the SDK. In any case, I'm looking for solution that works for 1.5 and upwards.
I am trying to launch an app widget from another application. On click of a button in an application, the appwidget is receiving the message i broadcasted.I have implemented the appwidgetprovider class. In the appwidgetprovider class, in the onReceive function i am able to get the broadcasted message.

<intent-filter> <action android:name="android.intent.action.VIEW">

I load the link in WebView:
mWebView.loadData("<a href="my_scheme://launch_my_app/refresh_all ">Launch App</a>", "text/html", "utf-8");
When I click on the link I get the error -10 "The protocol is not supported" in My WebViewClient.OnReceivedError override.
I created an app with one activity, and it works just fine. Having though more about the app, I decided to add another activity which be the welcome screen of the app, with a nice logo and some buttons. This app should direct the user to the activity I mentioned before. The only trouble is - I can't find out where and how can I determine which activity should launch first, the moment the app loads. Do I need to create the entire app from scratch, but this time programing the home activity first?

View 5 Replies View RelatedMy music application constantly plays music in the background, however I'd like to be able to detect when another application starts playing audio (such as the YouTube app) so I can pause/mute/stop the audio in my application. This will allow a user to continue browsing the web whilst listening to music, but then if they wish to watch a video at any point, they can do so without audio conflict.
One solution might be to listen for a broadcast which states when an application begins using the AudioManager. Does such an Intent Action exist? Edit: As in the answer provided below, there appears to be a method of detecting the loss of audio focus in 2.2 with AudioManager.OnAudioFocusChangeListener.
I've run this on a device and on the emulator. The app stops unexpectedly on both. I have not a clue what is wrong currently. It uses Google API Maps I compiled with Google Api 7. I followed this tutorial:
http://developer.android.com/guide/tutorials/views/hello-mapview.html
I did use the correct API Key That the final apk is signed with. This is the source(If you compile it shouldn't work as it is unsigned). This is the compiled signed apk

I've been programming Android in Eclipse for about a year now and I have always launched my app by right clicking on my project name in the project explorer, followed by "run as", then "Android Application". There has to be a better way...
Is there a way to change this (three mouse clicks): "Right click on project" -> "run as" -> "Android Application"
To this (one hotkey press): <My favorite hotkey>
So I can just press one button to launch my app?
I have an application with two activities and I'd like to be able to have two icons appear in the launcher, each launching the respective activity within the app.Specifically, I want one icon to launch my main app, and another icon to launch my settings activity. Is this possible?This creates two launcher icons, but they both run my main app instead of the second icon running my settings app. I've tried just having the launcher category but then I don't get an icon so it looks like I need the main action as well.Is this the right approach or should I be declaring two applications in the manifest instead?
