Custom_CameraActivity.java

public class Custom_CameraActivity extends Activity {     private Camera mCamera;     private CameraPreview mCameraPreview;      /** Called when the activity is first created. */     @Override     public void onCreate(Bundle savedInstanceState) {         super.onCreate(savedInstanceState);         setContentView(R.layout.main);         mCamera = getCameraInstance();         mCameraPreview = new CameraPreview(this, mCamera);         FrameLayout preview = (FrameLayout) findViewById(R.id.camera_preview);         preview.addView(mCameraPreview);          Button captureButton = (Button) findViewById(R.id.button_capture);         captureButton.setOnClickListener(new View.OnClickListener() {             @Override             public void onClick(View v) {                 mCamera.takePicture(null, null, mPicture);             }         });     }      /**      * Helper method to access the camera returns null if it cannot get the      * camera or does not exist      *       * @return      */     private Camera getCameraInstance() {         Camera camera = null;         try {             camera = Camera.open();         } catch (Exception e) {             // cannot get camera or does not exist         }         return camera;     }      PictureCallback mPicture = new PictureCallback() {         @Override         public void onPictureTaken(byte[] data, Camera camera) {             File pictureFile = getOutputMediaFile();             if (pictureFile == null) {                 return;             }             try {                 FileOutputStream fos = new FileOutputStream(pictureFile);                 fos.write(data);                 fos.close();             } catch (FileNotFoundException e) {              } catch (IOException e) {             }         }     };      private static File getOutputMediaFile() {         File mediaStorageDir = new File(                 Environment                         .getExternalStoragePublicDirectory(Environment.DIRECTORY_PICTURES),                 "MyCameraApp");         if (!mediaStorageDir.exists()) {             if (!mediaStorageDir.mkdirs()) {                 Log.d("MyCameraApp", "failed to create directory");                 return null;             }         }         // Create a media file name         String timeStamp = new SimpleDateFormat("yyyyMMdd_HHmmss")                 .format(new Date());         File mediaFile;         mediaFile = new File(mediaStorageDir.getPath() + File.separator                 + "IMG_" + timeStamp + ".jpg");          return mediaFile;     } } 

CameraPreview.java

main.xml

<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"     android:layout_width="fill_parent"     android:layout_height="fill_parent"     android:orientation="horizontal" >      <FrameLayout         android:id="@+id/camera_preview"         android:layout_width="fill_parent"         android:layout_height="fill_parent"         android:layout_weight="1" />      <Button         android:id="@+id/button_capture"         android:layout_width="wrap_content"         android:layout_height="wrap_content"         android:layout_gravity="center"         android:text="Capture" />  </LinearLayout> 

Add Below Lines to your androidmanifest.xml file

<uses-feature android:name="android.hardware.camera" /> <uses-permission android:name="android.permission.CAMERA" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
