Intent startet nicht

Question

Ich versuche ein Bild aus der Kombüse auszuwählen und dann zu bearbeiten, ich mache es, indem ich einen Knopf auf der Hauptaktivität drücke, der dann eine neue Aktivität startet, in der man entweder a wählen kann bilde ein Bild ein oder wähle dein eigenes aus, und wenn ich mein eigenes Bild auswählen möchte, sollte es die Galerie öffnen und ein Bild auswählen, wie kommt das irgendwie nicht hin (obwohl es vorher funktioniert hat, denke ich, ich habe gerade etwas kaputt gemacht, aber nicht wissen, was)

mein Code:

package il.popov.ecptest; 

import android.app.ListActivity; 
import android.content.Intent; 
import android.database.Cursor; 
import android.graphics.BitmapFactory; 
import android.net.Uri; 
import android.os.Bundle; 
import android.provider.MediaStore; 
import android.view.View; 
import android.widget.AdapterView; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 

public class select_activity extends ListActivity { 

ListView listView; 
Intent intent;

    super.onCreate(savedInstanceState); 


    String[] StringArray = { 
     "Select your own", "image1", "image2", "image3", "image4", "None" 
    }; 
    setListAdapter(new ArrayAdapter <String> (this, R.layout.support_simple_spinner_dropdown_item, StringArray)); 
    intent = new Intent(this.getApplicationContext(), main_activity.class); 
    listView = getListView(); 
    listView.setTextFilterEnabled(true); 
    listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {@ 
     Override 
     public void onItemClick(AdapterView <? > arg0, View arg1, int position, long arg3) { 
      processClick(position);

      startActivity(intent); 
      break; 
     case 1:

    } 
}

     Cursor cursor = getContentResolver().query(selectedImage,

     cursor.moveToFirst(); 

     int columnIndex = cursor.getColumnIndex(filePathColumn[0]);

case 0: 
     //Intent i = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.INTERNAL_CONTENT_URI); 
     //startActivity(i); 

     Intent photoPickerIntent = new Intent(Intent.ACTION_PICK); 
     photoPickerIntent.setType("image/*"); 
     startActivityForResult(photoPickerIntent, 237); 

     //Returns to main activity , DO NOT CHANGE 
     startActivity(intent);// Remove this line in your case 0
