How to pass image path as parameter for an image to be taken from camera

Question

I am passing Image as parameter in this function:

twitt.shareToTwitter(string_msg, casted_image); (void chintan.khetiya.android.Twitter_code.Twitt_Sharing.shareToTwitter(String msg, File Image_url))

Now here I am selecting image from gallery, but now I want to take pic from cam and pass it. How to do it.?

Here is the full code:

public class MainActivity extends Activity {

// Replace your KEY here and Run ,
public final String consumer_key = "trWwomp0b09ER2A8H1cQg";
public final String secret_key = "PAC3E3CtcPcTuPl9VpCuzY6eDD8hPZPwp6gRDCviLs";
File casted_image;

String string_img_url = null, string_msg = null;
Button btn, pick, cam;
EditText et;
ImageView iv;
private static int RESULT_LOAD_IMAGE = 1;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    try {
        setContentView(R.layout.main);

        iv = (ImageView) findViewById(R.id.imageView1);

        pick = (Button) findViewById(R.id.button1);
        pick.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                // TODO Auto-generated method stub
                Intent i = new Intent(
                        Intent.ACTION_PICK,
                        android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);

                startActivityForResult(i, 1);
            }
        });

        cam = (Button) findViewById(R.id.button2);
        cam.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {

Intent:

Intent takePicture = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
startActivityForResult(takePicture, 0);

To fetch that result:

protected void onActivityResult(int requestCode, int resultCode, Intent imageReturnedIntent) {
   super.onActivityResult(requestCode, resultCode, imageReturnedIntent);

   switch(requestCode) {
   case 0:
       if (requestCode == 0 && resultCode == RESULT_OK) {
        Bitmap photo = (Bitmap) data.getExtras().get("data");           
        // CALL THIS METHOD TO GET THE URI FROM THE BITMAP
        Uri tempUri = getImageUri(getApplicationContext(), photo);
        // CALL THIS METHOD TO GET THE ACTUAL PATH
        casted_image = new File(getRealPathFromURI(tempUri));
        System.out.println(tempUri);
    }  
   break;
   case 1:
       //handle gallery code here

        break;
  }
}

public Uri getImageUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
    return Uri.parse(path);
}

public String getRealPathFromURI(Uri uriTemp) {
    Cursor cursor = getContentResolver().query(uriTemp, null, null, null, null); 
    cursor.moveToFirst(); 
    int mIndex = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA); 
    return cursor.getString(mIndex); 
}

Add this in your manifest.xml.

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

<uses-feature android:name="android.hardware.camera" />
<uses-feature android:name="android.hardware.camera.autofocus" />

Answer 2

to ask for a specific file location to the camera you have to do like this:

     Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
     cameraCaptureLocation = new File("... location goes here ...");
     intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(cameraCaptureLocation));
     startActivityForResult(intent, REQUEST_CAMERA);

But there is a problem, since I am using both cam and gallery at the same place, the function onActivityResult is already there. What to do now.?

then you have to use the requestCode to filter where that activity result come from. You pass one integer for REQUEST_CAMERA and another for REQUEST_GALLERY
