App crashing whilst displaying a dialog

Question

Im getting an error when i'm trying to call this method:

        okHttpClient.newCall(request).enqueue(new Callback() {
        @Override
        public void onFailure(Call call, final IOException e) {

            runOnUiThread(new Runnable() {
                @Override
                public void run() {
                    showErrorAlert(e.toString());
                }
            });
        }

//The Method:

public void showErrorAlert(String error) {
    AlertDialog.Builder dialogBuilder = new AlertDialog.Builder(ProjectListActivity.this);

    dialogBuilder.setMessage("Hmm, there seems to be an error downloading the project list. " + error);
    dialogBuilder.setCancelable(true);

    dialogBuilder.setPositiveButton(
            "Okay",
            new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    dialog.cancel();
                }
            });
    AlertDialog alert = dialogBuilder.create();
    alert.show();
}

So when the call fails, it will then instantly crash and this is the output in the console:

E/AndroidRuntime: FATAL EXCEPTION: main
                  Process: com.chimesoftware.chime.chimetimemanager, PID: 5770

                      at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:807)

Is this possible due to calling the error wrong? or possibly because of the type of error I am trying to display.

Thank you.

It is working for me, if you want to use that :

AlertDialog.Builder alertDialog = new AlertDialog.Builder(HelpAndSupport.this);
    alertDialog.setTitle("Confirm Sign out...");
    alertDialog.setMessage("Are you sure you want signout from Talentslist?");
    alertDialog.setPositiveButton("YES", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            //you posive click code here
        }
    });

    alertDialog.setNegativeButton("NO", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int which) {
            dialog.cancel();
        }
    });
    alertDialog.show();
