Capturing image from gallery & camera in android

问题:

First thing I know this is repeated question but I don't have problem in capturing image from gallery or camera. I created on dummy project to check my code here it's working fine But when I used same code in my project & here it's not working even I didn't get any error as soon as I start activity for result it get cancelled but still I can see images from gallery & I can capture image from camera.

When I checked logcat I found following warning don't know why it's coming & how I can fix this thing

 W/NetworkConnectivityListener(2399): onReceived() called with CONNECTED and Intent { act=android.net.conn.CONNECTIVITY_CHANGE flg=0x10000000 (has extras) }

Edit:-- Added Code

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    switch (item.getItemId()) {
        case R.id.camera:
            //define the file-name to save photo taken by Camera activity
            String 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 is the current activity attribute, define and save it for later usage (also in onSaveInstanceState)
            imageUri = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
            //create new Intent
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            intent.putExtra(MediaStore.EXTRA_OUTPUT, imageUri);
            intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);

Take a look at LinderdaumEngineActivity.java from my project Linderdaum Engine:

Capture image from camera:

public void CapturePhoto( String FileName )
{
    try
    {
        File f = new File(FileName);

        if ( f.exists() && f.canWrite() ) f.delete();

        Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
        intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,Uri.fromFile(f));
        intent.putExtra(MediaStore.EXTRA_VIDEO_QUALITY, 1);

        startActivityForResult(intent, CAPTURE_IMAGE_CALLBACK);
    }
    catch ( ActivityNotFoundException e )
    {
        Log.e( TAG, "No camera: " + e );
    }
    catch ( Exception e )
    {
        Log.e( TAG, "Cannot make photo: " + e );
    }
}

Open image from gallery:

public static void OpenImage()
{
    try
    {
        Intent intent = new Intent( Intent.ACTION_GET_CONTENT );
        intent.setType( "image/*" );
        startActivityForResult( intent, SELECT_PICTURE_CALLBACK );
    }
    catch ( ActivityNotFoundException e )
    {
        Log.e( TAG, "No gallery: " + e );
    }
}

Also, do not forget to add permissions to your manifest:

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

Please check your AndroidManifest, make sure you have all the right permissions.
