Camera Intent (Fresh Start from an emulator), no confirmation after taking one picture

I am just calling a camera intent like this:
Intent camera = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(camera, Constant.CAMERA);
Everything works fine, except when I start run this app for the first time.
I mean, if I wipe out data from my emulator, then start this app then,
The built-in Camera App shows some kind of first user tutorial if I start the camera intent.
After the tutorial, which is , even I take a picture, it does not show a confirmation check box. It keep stay as a built-in camera app and it does not return anything.
However, if I press back button and start the camera intent again, it works fine.
I am not sure how to prevent this kind of tutorial for the first time user.

I am not sure how to prevent this kind of tutorial for the first time user.
That is not possible. The decision of what a particular camera app will do in response to ACTION_IMAGE_CAPTURE is up to the developers of the camera app, not you or me.
Please bear in mind that ACTION_IMAGE_CAPTURE can wind up using any one of hundreds, if not thousands, of possible camera apps. The behavior of each of those camera apps will differ. And, since camera app developers do not seem to test ACTION_IMAGE_CAPTURE very much, you will get odd results like the one that you describe or various other things that you might consider to be a bug.

Android: setting file association without opening the app

My Android app has to allow the user choose which app will open a certain file format, exploiting the system chooser, so next time a certain intent is handled as the user decided.
I would like that it is able to open a chooser of apps for an intent but without opening the chosen app.
I mean, the chooser has to be called just to have the user choosing the app but the app wouldn't open.
Is it possible, maybe with a special intent or workaround?

Your requirement is a little bit like the one feature in "Android for Work", maybe you can check it.

android bypass app chooser

I understand that Android does not allow you to call an emergency number (911) directly. So I have decided to use Intent.ACTION_DIAL instead to leave the app and have the number pre-dialed, ready to call. However, the app chooser appears when I hit my 'Dial 911' button, adding another unnecessary step to the process (the other option besides the Phone app is to scan the number using Lookout Security).
Is there anyway to bypass the app chooser by pre-defining the app to handle the Intent?

There are many possible dialers. You have no good way of determining a priori which is the "one true dialer" that the user wants to use. Moreover, the user should be able to click "Always" on the chooser and therefore only encounter this once.
If you want, you could allow the user to choose their dialer up front, perhaps as part of configuring your app. You can use PackageManager and queryIntentActivities() to find out what all supports ACTION_DIAL, presenting that to the user to choose from. You would remember the ComponentName of their choice, and add that ComponentName to the ACTION_DIAL Intent that you use "for realz" when the user presses the button in your app.

Opening Camera in Portrait mode using Intent

I am able to open the device's Camera from my Activity using an Intent as follows:
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
Uri fileUri = getOutputMediaFileUri();
cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, fileUri);
cameraIntent.putExtra("android.intent.extras.CAMERA_FACING", 1);
startActivityForResult(cameraIntent, CAMERA_REQUEST);
My problem is my Activity is set to Landscape mode, so when the camera is opened, it is also opened in Landscape mode - but I need to open the Camera in Portrait mode only.
So please let me know how can I do this when using an Intent to launch the device's camera.
Thanks...

This is an issue with using external apps to handle functionality for you. In theory, apps that accept Intent actions should properly handle the Intent and return the data you are asking for, but in practice there is very little you can do to enforce this behavior...For example, any app can say it handles "image capture," but if you were to pass your Intent to a poorly programmed or malicious app, there is nothing preventing that app from doing something completely different than what you intended, or nothing at all. If you choose to let your app give up control to another app to fulfill certain functionality, you take the risk that whatever app is chosen cannot fulfill that functionality.
In your particular case where you are looking for the ability to add Intent extras, there is no way anyone can answer this question that would apply to all camera apps out there. You would need to find one that supports what you want, figure out how to force it into portrait mode, and then pray that all your users have that particular app installed. The are really very few options to always ensure that your app will take a picture the way you want it to:
Create a chooser for your camera Intent and limit the results to only apps that you have tested and know work as intended. If the particular apps are not installed, disable picture taking functionality.
Implement image capture yourself.

You can't force a third party app to launch in any particular orientation. In fact, I notice that whenever I launch the standard Camera app from my (portrait) app, the camera app switches to landscape.
If you set the more modest goal of making sure that the user is holding the phone in portrait when the camera is launched, what you need is a very simple third activity that is portrait only. Then:
Launch this activity from your landscape main app.
This activity has some portrait UI so the user will rotate the phone to read it.
This activity launches the camera, exactly as you are doing it above.
When this activity gets a result, it passes it straight through to your main activity with setResult()
To have any greater level of control, you would have to write your own camera app or require users to use a certain camera that does what you need.

None of the solutions work.There is nothing wrong with the layouts either.I got it to work by running on a higher version(API10 to API15). Weird!!

android custom intent chooser

We have an app that starts an activity for SENDTO with the intention of letting the user send an email. the choice of all the various email apps is fine, but we'd like to give the user of bypassing that step in the future ... e.g., add a "remember this decision" button at the bottom of the chooser. from then on, we'd launch that specific activity instead of getting the chooser.
I'm wondering if we can interact with the built-in create chooser functionality at a lower level to affect this. If not, could someone point / post some code snippets for this? I suppose the trick is understanding how to get a list of activities that can handle the intent.

I've seen a lot of questions about modifying the app chooser, and they all seem to state that no, you cannot change the built-in app chooser, but you can create a custom app chooser using queryIntentActivities() in the PackageManager class.
