Android NullPointerException creating new Intent in Motorola device

Question

I have a button:

final Button dialogButtonFotoPerfil1 = (Button) dialogFotosPerfil
            .findViewById(R.id.botonFotoPerfil1);
    dialogButtonFotoPerfil1.setOnClickListener(new MediaGaleryActivity());

which I want to show an image picker. MediaGaleryActivity.java is:

import android.app.Activity;
import android.content.Intent;
import android.database.Cursor;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.net.Uri;
import android.provider.MediaStore;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.ImageView;

import com.gayworld.R;
import com.gayworld.utils.Utilidades;

public class MediaGaleryActivity extends Activity implements OnClickListener {
    private static final int SELECT_IMAGE = 1;
    private static  String TAG; 

    @Override
    public void onClick(View v) {
        TAG = "MediaGaleryActivity.onClick";
        Log.d(TAG, "Inicio.");
        Intent intent = null; 
        switch (v.getId()) {
        case R.id.botonFotoPerfil1: 

                intent = new Intent(Intent.ACTION_GET_CONTENT);
                intent.setType("image/*");    
                Log.d(TAG, "Error valor gallery "+intent.toString());
                  startActivityForResult(Intent.createChooser(intent,
                            "Select Picture"),SELECT_IMAGE); 
            break; 
        default:
            break;
        }

    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
      super.onActivityResult(requestCode, resultCode, data);
      TAG = "MediaGaleryActivity.onActivityResult";
        Log.d(TAG, "Inicio.");

      if(resultCode==RESULT_OK && requestCode==SELECT_IMAGE){
       Uri selectedImage=data.getData();
       String path=getPath(selectedImage);

       Bitmap bitmapImage=BitmapFactory.decodeFile(path);
       ImageView image=(ImageView)findViewById(R.id.image);
       image.setImageBitmap(bitmapImage);

      }
    }

    public String getPath(Uri uri){
         TAG = "MediaGaleryActivity.getPath";
            Log.d(TAG, "Inicio.");

      String[] filePathColumn={MediaStore.Images.Media.DATA};

      Cursor cursor=getContentResolver().query(uri, filePathColumn, null, null, null);
      cursor.moveToFirst();
      int columnIndex=cursor.getColumnIndex(filePathColumn[0]);

      return cursor.getString(columnIndex);
    }

}

But I´m getting a NullPointerException.

I get this error and I don´t know what I can do more. I have been reading a lot of blogs, answers,.. I also ask for google help... but nothing. I always get the same error. Any idea?? Because I´m really stuck with it.

Thanks in advance.

Answer 1

Are you sure your MediaGalleryActivity has context?

Check this out, the user was doing something similar and getting a NPE on startActivity -> https://stackoverflow.com/a/16748203/2114852

Other than that, you'd have to provide the full logcat as the comment suggests.
