1. Android Introduction
Camera

2. Goal
Create an application that launches the built-in Camera and use the results for displaying the captured image.

3. Layout Make a LinearLayout with
a TextView,
a Button, and
an ImageView
Create a handler for the OnClick event of the Button

4. Launch Camera
Creating an Intent, as follows, within your button click handler:
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
Launch camera activity with asking result:
startActivityForResult(cameraIntent, CAMERA_PIC_REQUEST);  
define within your application as the request code returned by the Camera image capture Intent
private static final int CAMERA_PIC_REQUEST = 1; 

5. Handling result from Camera
By adding onActivityResult() in your Activity:
protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    if (requestCode == CAMERA_PIC_REQUEST) {
// display image   
        Bitmap thumbnail = (Bitmap) data.getExtras().get("data");
ImageView imageTakePic = (ImageView) findViewById(R.id.imageViewPhone);
imageTakePic.setImageBitmap(thumbnail);
    }   } 

6. Enforcing Device Requirement
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="
package="ucab.test.camera"
android:versionCode="1"
android:versionName="1.0">
<uses-sdk android:minSdkVersion="7" />
<uses-feature android:name="android.hardware.camera"></uses-feature>
<application
<activity android:name=".AndroidCameraActivity"
<intent-filter> :
Application wants a camera
It is not enforced by Android
