I'm a little bit speechless.  

I have activity A and B.
When I'm in B and get the method `deleteItemOption( much input )` then the Toast crashes my app :D

if I open the method in activity A everything is fine.
But I need the method in activity A and B, so I programmed the methode global but the Toast is a little bit nasty :D

in the `.setpositiveButton` there is a Toast.
Why does the Toast crash my App if there stands:

```
Toast.makeText(context, getText(R.string.deleted).toString(), Toast.LENGTH_LONG).show();

```

or:

```
Toast.makeText(context, getString(R.string.deleted), Toast.LENGTH_LONG).show();

```

but this works:

```
Toast.makeText(context, "deleted", Toast.LENGTH_LONG).show();

```

EDIT: also I found out that this works:

```
public void deleteItemOption(.... ,final String toast2, ....){
...
    Toast.makeText(context, toast2, Toast.LENGTH_LONG).show();
...
}

```

I get my context from there:

```
public boolean onOptionsItemSelected(MenuItem item) {
        switch (item.getItemId()) {
            case R.id.deleteHersteller:
                ListView listViewDelete = (ListView) findViewById(R.id.listViewHersteller);
                String toast2 = getText(R.string.deleteSuccesfully).toString();
                deleteItemOption(Hersteller.this, listViewDelete, getText(R.string.takeHersteller).toString(), toast2 , mainFolder, getText(R.string.hersteller).toString(), getText(R.string.really).toString());
                return true;
        }
        return true;

```

The code in Class A:

```
public void deleteItemOption(final Context context, ListView listView, String toast, final String folder, final String title, final String really){
        Toast.makeText(context, toast, Toast.LENGTH_LONG).show();
        final ListView listViewDelete = listView;
        listViewDelete.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View view, final int position, long id) {
                final AlertDialog.Builder builder = new AlertDialog.Builder(context);
                final String deleteName = listViewDelete.getItemAtPosition(position).toString();
                builder.setPositiveButton(R.string.yes, new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int id) {
                        deleteFolder(folder + deleteName);
                        setContent(context, folder, listViewDelete);
                        //this Toast chrash the app
                        Toast.makeText(context, getText(R.string.really).toString(), Toast.LENGTH_LONG).show();
                        //recreate();
                        /* würde gut funktionieren wenn man den ganzen Code überall in jeder activity stehen hat aber da ich
                        global eine Methode gemacht habe, geht das recreate() nicht*/

                    }
                })
                        .setNegativeButton(R.string.no, new DialogInterface.OnClickListener() {
                            public void onClick(DialogInterface dialog, int id) {
                                //recreate();
                                return;
                            }
                        });
                AlertDialog alertDialog = builder.create();
                String titleString = title+" '"+deleteName+"' "+really;
                alertDialog.setTitle(titleString);
                alertDialog.show();
            }
        });

    }

```

string.xml

```

    <string name="deleteGeschossQuestion">Geschoss wirklich löschen?</string>
