Question

This is my code:

 String _path = Environment.getExternalStorageDirectory() + File.separator +  "temp.jpg";
                           File file = new File( _path );
                           Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);             
                           Uri pictureUri = Uri.fromFile(file);
                           cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, pictureUri);
                           startActivityForResult(cameraIntent, CAMERA_REQUEST);

protected void onActivityResult(int requestCode, int resultCode, Intent data) {       
            switch(requestCode){
                case CAMERA_REQUEST:{
                    Bitmap bmp = (Bitmap) data.getExtras().get("data");    

and I have added in the manifest the:

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

What am I doing wrong? What i want at first is to save the image?

Answer 1

your are getting data part null bez you are not setting intent.setDataAndType() when you are starting Acitivty.if you want to take data as Bitmap then start camra activity as:

public static final String IMAGE_UNSPECIFIED = "image/*"; 
    Intent intent = new Intent(Intent.ACTION_PICK, null);  
    intent.setDataAndType(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, IMAGE_UNSPECIFIED);  
    startActivityForResult(intent, 3);  

    protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    if (resultCode == 0)  
       return; 
    if (requestCode == 2) {  
       Uri uri=data.getData();  //YOU GET DATA HERE
        }  
//OR
if (requestCode == 3) {  
 Bundle extras = data.getExtras();  
 if (extras != null) {  
 Bitmap photo = extras.getParcelable("data");  
 ByteArrayOutputStream stream = new ByteArrayOutputStream();  
 photo.compress(Bitmap.CompressFormat.JPEG, 75, stream);// (0 - 100)????  
 imageView.setImageBitmap(photo);  
  }  
}  

or in your case getting image path use:

if (requestCode == CAMERA_REQUEST) {  
     //pic path
      File picture = new File(Environment.getExternalStorageDirectory() + "/temp.jpg");  
   }
