Android :: Camera Button Press Fails To Invoke BroadcastReceiver
Aug 6, 2010
I am trying to capture the camera button press event and get the image in my app. I have a broadcast receiver in my manifest with intent filter having action but when the camera button is pressed in emulator, the CameraClickBroadcastReceiver.onReceiver() method is not invoked. In this method i am starting an activity which is the home activity of my app.

Essentially, what I'd like to do is to be able to press the 'back' button on my Hero to take a picture, rather than pressing the trackball.

well a couple of questions actually. So first is it possible to only view pictures taken by the camera when I press the review button in the camera app? for example, not only do the pictures I take come up but also pictures of wallpapers and other saved images located in different folders show up. I also wanted to know if it was possible to have the take picture button be moved to the hold button.

I'm trying to make an app where a button will invoke a web service's API call (it'll be my own web service; the call/functionality is not relevant). I know how to make a new listener that invokes an activity, but that is insufficient here since I'll still need to make a call out to a web service through it. What is it I'm doing here? Is this a service that I'm looking at? content provider that I'll be invoking that somehow gets data from a web service?

I have the Samsung SGS3 running on ICS and I am looking for a possibility to invoke the stock TW app switcher (the one that appears when you keep the home button pressed) via a homescreen widget/button/whatever.
One of the other launchers I've tried (was it Go launcher or Apex?) had such a button at the homescreen: When pressed, the action launched the app switcher.

I'm trying to build a simple video recorder for an Android device and I've had limited success and mixed results. It worked once, but now, without changing anything, I'm getting a "Camera is not available" error followed by "prepare failed -2147483648" error.

I am trying to catch when the user has pressed the Home button. I thought I could use
protected void onResume()
{
registerReceiver(homeReceiver, new IntentFilter(Intent.CATEGORY_HOME));
}
...
private BroadcastReceiver homeReceiver = new BroadcastReceiver()
{
public void onReceive(Context context, Intent intent)
{
// logic here
}
};
but that doesn't seem to work. I understand that onPause will be called, but my particular app has some logic that I need to handle separately. Short story is based on some info coming in, the app will display new Activities to the user. To prevent Back button issues, as each Activity hits it's onStop it calls finish on itself. However if the user presses the Home button I do not want the Activity to call finish so that when the user presses the app icon on the home screen or via the Recently run apps list, the last Activity is brought back

I realize the Camera button on the Droid X is not a standard feature across all phones, so, I'm curious how to attach a callback to it. I have a camera application that I wrote and I want the user to be able to snap the picture by pressing that button, but currently it doesn't work that way, so, I'm wondering how to attach my callback to it.

My application uses GPS updates while it is running and I would like that to stop when the user back out of the app as I assume it will continue wasting a lot of battery power. I've tried intercepting the back button press but it doesn't seem to work. I'm not sure if this is because it's not executing the code or I'm using the wrong command.

I'm creating an Android application which uses user captured images as part of a larger process. So far my XML layout has a SurfaceView and Button inside a RelativeLayout. I've managed to get the camera preview to show on the SurfaceView but I'm stuck on how to take a picture and save it when a user presses the button.

I started a small android application to learn. I placed an input text and button on the screen. That shows on the emulator. After i press the button(which has an onClickListener) the application cracks and tells me on the screen of the emulator : "The application... has stopped unexpectably.Try again" and i have a "Force close", which of course closes the application.
I cleaned and rebuild the project a lot of times. i have no errors shown.(using eclipse)
this is the layout/main.xml code...

I take the grandkids to the Cleveland Zoo today. I'm taking photos with my $500 Canon G10 digital camera and all of a sudden... It's taking horrible white washed out images, then purple images. Finally, the images are all black. My processor, or CCD died in the camera...Bust out my Incredible and keep on keepin on...
Here's a few from the inc. I've resived them to 25% and saved them at 80%. I can't complain at all! Because my Incredible SAVED MY DAY!

How can I capture a long press of the device menu button in my application?I thought of an intent filter, but there's only an action called android.intent.action.SEARCH_LONG_PRESS, but nothing for the MENU button.I found that long press of the menu button actually does different things on different devices,i.e. on Nexus One it will show the soft keyboard, while on Samsung Galaxy S it will pop up the search widget.

The docs say "The onStart() and onStop() methods can be called multiple times, as the activity alternates between being visible and hidden to the user"When I press the back button an it will go back to the previous activity which totally covers the old one.What is going on here?

I have an Activity with an EditText, a button and a ListView. The purpose is to type a search screen in the EditText, press the button and have the search results populate this list. This is all working perfectly, but the virtual keyboard is behaving strange. If I click the EditText, I get the virtual keyboard. If I click the "Done" button on the virtual keyboard, it goes away. However, if I click my search button before clicking "Done" on the virtual keyboard, the virtual keyboard stays and I can't get rid of it. Clicking the "Done" button does not close the keyboard. It changes the "Done" button from "Done" to an arrow and remains visible.

What i'm trying to do is just simply have the button load an image at random. However, the button doesn't seem to be working. When i first load the activity there it works fine and there is a random image....But when i press the button it's not loading another like i need it to. Any idea what i have wrong here? It looks fine to me...

When I start the camera or camcorder app, they fail every time with this error message.The application Camera (process.android.camera) has stopped unexpectedly. Please try again." and a Force Close button. I know they transferred everything from my Motorola phone.. could there be an incompatibility problem with data transferred from my Motorola or is the camera hardware just faulty? Are there any steps I can take to troubleshoot?

I have a homescreen widget with an imagebutton. I have the button working with a pending intent, but I can't seem to figure out how to change the button image when it is pressed. I tried using a selector and it works in my widget test activity, but not in the remoteview. How could I implement this functionality in the home screen widget?

It is difficult to test a game with the mouse pointer on android buttons. I would like to control those buttons with the hardware keyboard. Actually I don't want to control the buttons itself but I want to control the behavior the buttons would also do. For example I have 4 buttons in the android application with "arrow up, down, left, right". I'd like to use the arrow buttons of my hardware keyboard to control the same. How can I do that? Actually the question is, where can I set the Listener? I tried something in my activity.
