save the path of camera image into SQLite table and retrieve it

I have posted this problem yesterday..but unfortunately, no one has given me the solution and I still dont know where my mistake is.

I just want to save the path of an image taken by the camera into a SQLite table. And afetr that I want ot retrieve this path from the database and display the picture.

Code:

public void takePic() {
    String fileName = "temp.jpg";  
    ContentValues values = new ContentValues();  
    values.put(MediaStore.Images.Media.TITLE, fileName);  
    mCapturedImageURI = getContentResolver().insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);  

    cameraIntent = new Intent(android.provider.MediaStore.ACTION_IMAGE_CAPTURE);
    cameraIntent.putExtra(MediaStore.EXTRA_OUTPUT, mCapturedImageURI);
    startActivityForResult(cameraIntent, Camera_requestCode);
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == Camera_requestCode && resultCode == RESULT_OK) {
        String[] projection = { MediaStore.Images.Media.DATA}; 
        Cursor cursor = managedQuery(mCapturedImageURI, projection, null, null, null); 
        int column_index_data = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); 
        cursor.moveToFirst(); 
        String capturedImageFilePath = cursor.getString(column_index_data);

        insertPath(capturedImageFilePath);
        Bitmap image = (Bitmap) data.getExtras().get("data");
    }
};

Change your code,

protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == Camera_requestCode && resultCode == RESULT_OK) {

       if(data != null)
       {
        String[] projection = { MediaStore.Images.Media.DATA}; 
        Cursor cursor = managedQuery(mCapturedImageURI, projection, null, null, null); 
        int column_index_data = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA); 
        cursor.moveToFirst(); 
        String capturedImageFilePath = cursor.getString(column_index_data);

        insertPath(capturedImageFilePath);
        Bitmap image = (Bitmap) data.getExtras().get("data");
      }
     else
     {
       Log.e("OnActivityResult()", "data is null");
     }
    }
};
