Android Camera : data intent returns null

Question

I have an android application which contains multiple activities.

In one of them I\'m using a button which will call the device camera :

public void         


        

Answer 1

When we will capture the image from Camera in android then Uri or data.getdata() comes null. we have two solutions to resolve this issue.

1. We can got the Uri path from the Bitmap Image
2. We can got the Uri path from cursor.

I will implement all methods here, Please carefully watch and read these:-

First i will tell how to get Uri from Bitmap Image: Complete code is :

First we will capture image through Intent that will same for both methods so this code i will write one time only here :

// Capture Image
captureImg.setOnClickListener(new View.OnClickListener(){
    @Override public void onClick(View view){
        Intent intent=new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        if(intent.resolveActivity(getPackageManager())!=null){
            startActivityForResult(intent,reqcode);
        }

    }
});  

Now we will Implement OnActivityResult :-(This will be same for both above 2 methods):-

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
    super.onActivityResult(requestCode, resultCode, data);

    if (requestCode == reqcode && resultCode == RESULT_OK)
    {

        Bitmap photo = (Bitmap) data.getExtras().get("data");
        ImageView.setImageBitmap(photo);

        // CALL THIS METHOD TO GET THE URI FROM THE BITMAP
        Uri tempUri = getImageUri(getApplicationContext(), photo);

        //Show Uri path based on Image
        Toast.makeText(LiveImage.this, "Here " + tempUri, Toast.LENGTH_LONG).show();

        //Show Uri path based on Cursor Content Resolver
        Toast.makeText(this, "Real path for URI : " + getRealPathFromURI(tempUri), Toast.LENGTH_SHORT).show();
    }
    else
    {
        Toast.makeText(this, "Failed To Capture Image", Toast.LENGTH_SHORT).show();
    }
}     

Now we will create all above method to create Uri from Image and Cursor methods via classes:

Now URI path from Bitmap Image

private Uri getImageUri(Context applicationContext, Bitmap photo)
{
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    photo.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = MediaStore.Images.Media.insertImage(LiveImage.this.getContentResolver(), photo, "Title", null);
    return Uri.parse(path);
}

\ Uri from Real path of saved image

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