Android :: Enabling Camera In Emulator
Jun 19, 2009
I've just noticed that launching the Camera and Camcorder (in the emulator) would result in a black screen (instead of the famous moving small boxes), i've looked for why this happening on the net, apparently that the camera is disabled by default when you create an AVD. Decided to create another AVD with the camera enabled and launched it and still getting that black screen. Anyone has any idea how to fix this ?
My problem in the first place is that my application is using the default camera application using intents just like in the following: Intent imageCaptureIntent = new Intent (MediaStore.ACTION_IMAGE_CAPTURE); imageCaptureIntent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File("/sdcard/imageCaptureIntent.jpg"))); startActivityForResult(imageCaptureIntent, WHATEVER_REQ_CODE); I thought that there's a problem in my intent request but like i said before, running the camera on the emulator itself is the problem. By the way, You can run the "camera preview" in the API demos with no problems, how come!

How do you turn on sync in the emulator. I'm already using Google APIs level 8 and I've already created a Google account. But under "Manage Accounts", my Google account says "Sync is OFF".

Strange behaviour with emulator running with Cupcake. When emulator is launched (via ADT), a SD card is mounted correctly, and I click on Camera, I have a black screen and nothing happens, I got the famous error with Wait or Force close wait, wait, wait nothing happens. I create with AVD the target 3. I'm on Windows XP SP2.

I wish to simulate camera in the android emulator using the webcam. Basically I need to only take photos with the camera in the emulator (live preview is not needed i.e if it makes it any easier) I followed the tutorial here which is the only one I could find that was close to my requirements But many of the libraries used in that tutorial(like android.hardware.CameraDevice) are not available in present sdk and are replaced by new libraries(like android.hardware.camera). Any help on how to do this in the present sdk(2.1 or 2.2) would be much appreciated.

We are exploring the default applications in Froyo and we found out that the Camera app always crashes seconds after it loads.
Is this related to the no camera/video input limitation of the application? If not, what seems to be the problem? We already added all the additional properties to the AVD. We also disabled the auto-rotate screen option.

I have 1.0 r2 and it takes garbage pictures, and crashes when trying to view any saved image (I've only saved images taken from the emulator's "camera" so I don't know if it shows images that were pushed via adb properly.)
I'll try the 1.1 SDK, and failing that, an earlier version.
Is this a known issue, sort of a "well, if you're really going to work with pictures, you should be using a G1 anyhow..." kind of thing?

As far as i know, Android emulator doesn't have a camera. To capture a live image we have to use the web camera. I have seen code in this web site to use the web camera in the android emulator to capture an image, but I don't know how to use this code.

The Emulator's camera worked fine for taking pictures in 2.1 Eclair. What did not work was recording videos, obviously.
Now running an app which worked merely flawless on 2.1 Emulator causes the camera app to crash. I fire up an intent to launch it:
CODE:...................
This starts the camera app but after a few seconds it crashes.
The output is:
CODE:.................
Actually I just wanted to see if the bug which made you receive a small image from the camera even though EXTRA_OUTPUT was specified has been fixed in FroYo. Unfortunately, I don't even get to test it.

I am using Android 2.2 (API Level 8). The camera is enabled in the manifest. When I try the camera icon provided by the emulator model, it runs for a few seconds showing a gray box moving around a black and white checkerboard, then dies with the error message...

I'm using the android SDK in Eclipse on Linux. I've used the code at itp.nyu.edu/~sve204/mobilemedia_spring10/androidCamera101.pdf to write an app to store an image captured through the camera onto SD card (there are various examples of this around). It works ok except that the image returned by the camera is not what's on the preview surface. Instead of getting the checkerboard image I expect, I get different versions of the android icon depending on which version of target I choose. If I render the image to an ImageView this is confirmed as it's the same as on the SD card.

The camera button on the android emulator is disabled. I can't click on it and when I hover with the mouse the background is not blue like in the other buttons. I've tried to add "camera support - true" hardware but the button is still un-clickable. How can I click on the button? What should happen when clicking on the button? I don't have an real android device so I might be able to click on the button without knowing it.

I am new to Android development and have trouble enabling / disabling the wifi & audio services. I get the appropriate manager instance using the getSystemService method. But I don't get any error when enabling wifi using:
wifiMgr.setWifiEnabled(true);
But the wifi is simply not turned on! Similarly I use
mAudio.setRingerMode(AudioManager.RINGER_MODE_SILENT);
or
mAudio.setRingerMode(AudioManager.RINGER_MODE_NORMAL);.....................

I need to enable a MenuItem when a previous screen (Activity) returns. I tried this code:
...
((MenuItem)findViewById(R.id.menu_how)).setEnabled(true);
...
but a null pointer exception is launched. BTW, the menu_how is set to false in xml; and the code is part of onActivityResult(int requestCode, int resultCode, Intent data) call.

I have written code to enable and disable various things programatically like Wifi, Ringer modes, Airplane modes. All things that you would see in a power toggle widget. The one that I have not found out how to do is bluetooth. It appears that in SDK level 3 (OS 1.5) there is no pretty bluetooth manager class. Has anyone pinpointed any good source examples on enabling and disabling bluetooth that will also be forwards compatible with users running 2.0 (Droid) / 2.1 (Nexus)? I have found a few partial examples in my google searches that I could not get to actually run.

I have used PreferenceActivity to have preference in my android application. I want one preference say "pref 2" to be enabled when other preference say "pref 1" is not checked and "pref 2" to be disabled when "pref 1" is checked. i.e. exactly opposite of the android: dependency attribute. How can I do that?

In one of my applications I am dynamically enabling the GPS system setting based on a user's request. My problem is that I also have a LocationListener which doesn't pick up this change. If the device is restarted or the system settings Activity is brought up the LocationListener kicks in -- the onProviderEnabled() method is called. So.. it seems pretty obvious that I'm not notifying the system correctly of my changes. I have tried sending a broadcast from both the normal context and the application context. I thought this would be fairly straight forward, but it has proven to be rather frustrating. I put together a small test activity to demonstrate my problem.
Here is my test Activity: package com.example;
import android.app.Activity; import android.content.Context;
import android.content.Intent; import android.location.Location;
import android.location.LocationListener; import android.location.LocationManager;
import android.os.Bundle; import android.provider.Settings; import android.util.Log;
public class TestActivity extends Activity {
LocationListener locListener; LocationManager locManager;
@Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState);
setContentView(R.layout.test_activity); locListener = new MyLocationListener();
locManager = (LocationManager)getSystemService (Context.LOCATION_SERVICE);
locManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locListener);
if(!locManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {
Settings.System.putString(getContentResolver (),
Settings.System.LOCATION_PROVIDERS_ALLOWED, LocationManager.GPS_PROVIDER);
Intent intent = new Intent(Intent.ACTION_PROVIDER_CHANGED);
sendBroadcast(intent); } }
private class MyLocationListener implements LocationListener {
public MyLocationListener() { Log.d("test", "MyLocationListener()");
} public void onLocationChanged(Location loc) {
Log.d("test", loc.getLatitude() + "/" + loc.getLongitude());
} public void onProviderDisabled(String provider) {
// TODO Auto-generated method stub Log.d("test", "*** onProviderDisabled (" + provider + ") ***");
} public void onProviderEnabled(String provider) {
// TODO Auto-generated method stub Log.d("test", "*** onProviderEnabled (" + provider + ") ***");
} public void onStatusChanged(String provider, int status, Bundle extras) {
// TODO Auto-generated method stub Log.d("test", "*** onStatusChanged ***");
Log.d("test", "provider = " + provider + " status = " + status);
} } }

Under the 2.1 SDK, is there a way to test for the phone's OS version within the app, and to enable or disable features based on this OS version? In other words, I'd like to do the moral equivalent of this...
if (os_level < 1.6) {// code goes here}

I have an application that has multiple activities with the intent action.MAIN (category LAUNCHER), so that multiple shortcuts appear in the "Applications" list. Is it possible to disable some of these activities at run-time (so that the corresponding shortcuts disappear from the "Applications" list)?

All, How can we enable LOG messages in Webkit.
I wanted to enable some debug prints using log utility of Android in Webkit I added the following statements in my code.
#define LOG_TAG "webkit" include <utils/Log.h>
And the following line to test LOGV("Constructor CachedImage.cpp");
I am unable to get the logs. Should I enable with the following define. I even added liblog as one of the shared libraries during compilation.
#define LOG_NDEBUG 0 /* Is this required to get logs? */

I have a very hard time with the slide to answer feature. It frequently takes me 3-5 tries to answer a call. I would much rather be able to touch to answer. I do realize that there's a slim chance of answering calls while in my pocket, but I'd rather that then fight with the phone. Does anyone know of an application for this? I've searched various forums and there are no current threads regarding this.
