Question

I am taking a high resolution picture through the default camera activity(using intent.put Extras),and saving it to the sd card,

Code:

public class CameraActivity extends Activity implements OnClickListener {
    /** Called when the activity is first created. */

    Button takepicture ;
    ImageView iv ;
    TextView tv;
    Button show;

    String filepath;
    Intent i;
    Uri mUri;

    final static int cameraData = 0;

    File folder = null;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        takepicture = (Button) findViewById(R.id.button1);
        iv = (ImageView) findViewById(R.id.imageView1);
        tv = (TextView) findViewById(R.id.textView1);
        show = (Button) findViewById(R.id.button2);
        takepicture.setOnClickListener(this);
        show.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub

        switch(v.getId()){

        case R.id.button1:

            String sdcardstate = android.os.Environment.getExternalStorageState();

            if(sdcardstate.contentEquals(android.os.Environment.MEDIA_MOUNTED)){

                 filepath = Environment.getExternalStorageDirectory().getPath();

                 folder = new File(filepath,"wax");

                 if(!folder.exists()){
                     try {
                        folder.createNewFile();
                         Log.d("folder created", "ya");
                    } catch (IOException e) {
                        // TODO Auto-generated catch block
                        e.printStackTrace();
                    }
                 }

                 mUri = Uri.fromFile(folder);
                 Log.d("bk", mUri.toString());

                 i = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
                 i.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, mUri);

                 Log.d("extra", "extra");
                 startActivityForResult(i,cameraData);
            }
            break;

        case R.id.button2:

            File f = new File(filepath,"bmp.png");

            Bitmap myBitmap = BitmapFactory.decodeFile(f.getAbsolutePath());              

            iv.setImageBitmap(myBitmap);                
            break;
        }           
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        // TODO Auto-generated method stub
        super.onActivityResult(requestCode, resultCode, data);

        if(resultCode==RESULT_OK){

            tv.setText("Result ok");
            Log.d("ok", "ok");
            Bundle extras = data.getExtras();

            Bitmap bmp = (Bitmap) extras.get("data");
        }
    }
}

The camera activity starts , the image is taken , But when i click save , it does not return and force closes.

I have read quite a few threads on this , Learnt that file must be created before the camera activity is started , but still it does not.

Please help , I’m stuck on this problem for a week or so.

Answer 1

Use following to achieve this.

Before you call CameraIntent create a file and uri based on that filepath as shown here.

filename = Environment.getExternalStorageDirectory().getPath() + "/test/testfile.jpg";
imageUri = Uri.fromFile(new File(filename));

// start default camera
Intent cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
cameraIntent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,
                imageUri);
startActivityForResult (cameraIntent, CAMERA_PIC_REQUEST);

Now, you have the filepath you can use it in onAcityvityResult method as following,

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if(requestCode != CAMERA_PIC_REQUEST || filename == null)
        return;
    ImageView img = (ImageView) findViewById(R.id.image);
    img.setImageURI(imageUri);
}
