open camera using intent

Question

I want to use intent to open camera in Android .

I used the following code but when i press the button (whose action is onclick() function the app closes on itself .

 public void onclick(int actionCode){
     Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
     startActivityForResult(takePictureIntent, actionCode);
} 
public static boolean isIntentAvailable(Context context, String action) { 
    final PackageManager packageManager = context.getPackageManager(); 
    final Intent intent = new Intent(action); 
    List<ResolveInfo> list = packageManager.queryIntentActivities(intent, PackageManager.MATCH_DEFAULT_ONLY); 
    return list.size() > 0;
}

If someone can help me .

Answer 1

please have a look at this code, this is working fine with me

//define the file-name to save photo taken by Camera activity
fileName = "new-photo-name.jpg";
//create parameters for Intent with filename
ContentValues values = new ContentValues();
values.put(MediaStore.Images.Media.TITLE, fileName);
values.put(MediaStore.Images.Media.DESCRIPTION,"Image capture by camera");
imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);
startActivityForResult(intent, CAPTURE_IMAGE_ACTIVITY_REQUEST_CODE);

also apply this method to read image when you taken the image from camera.

    //handling intent responses
  @Override
  protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (resultCode == Activity.RESULT_OK)
      try {
        if (bitmap != null) {bitmap.recycle();}

        String[] proj = { MediaStore.Images.Media.DATA };
        Cursor cursor = managedQuery(imageUri, proj, null, null, null);
        int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
        cursor.moveToFirst();
        imageUriString = cursor.getString(column_index);

        getContentResolver().notifyChange(imageUri, null);
        ContentResolver cr = getContentResolver();

        try {
            bitmap = android.provider.MediaStore.Images.Media.getBitmap(cr, imageUri);
            imageButtonPictureShop.setImageBitmap(bitmap);

// this.uploadImage(); this.executeMultipartPost(); // this.uploadFile(imageUriString); } catch (Exception e) { Toast.makeText(this, "Failed to load", Toast.LENGTH_SHORT).show(); if(e.getMessage() != null)Log.e("Exception" , e.getMessage()); else Log.e("Exception" , "Exception"); e.printStackTrace(); }

      } 
    catch (Exception e) 
    {
        if(e.getMessage() != null)Log.e("Exception"  , e.getMessage());
        else Log.e("Exception"  , "Exception");
        e.printStackTrace();
    }

    super.onActivityResult(requestCode, resultCode, data);
  }
