POPUP on Boot Completed

Trying to create a popup after every boot is completed to get some confirmation. Able to get the BOOT_COMPLETED Message but while opening Alertdialog its crashing, Below are the code lines i am using. Please suggest

public class BootReceiver extends BroadcastReceiver {

    private static final String TAG = "BootReceiver";

    @Override
    public void onReceive(Context context, Intent intent) 
        {             
            String action = intent.getAction();         
            Log.d(TAG, "BroadcastReceiver:" + action);          
            if (action.equals(Intent.ACTION_BOOT_COMPLETED)) 
            {               

                Log.d(TAG, "ACTION_BOOT_COMPLETETED Receved" ); 
                CharSequence text = "BOOT COMPLETED!";
                int duration = Toast.LENGTH_SHORT;
                Toast.makeText(context,text,Toast.LENGTH_SHORT).show();

                AlertDialog.Builder alertDialog = new AlertDialog.Builder(context);
                alertDialog.setMessage("Message");
                alertDialog.setTitle("CONSENT");
                alertDialog.setIcon(android.R.drawable.ic_dialog_alert);
                alertDialog.setCancelable(false);
                alertDialog.setPositiveButton("AGREE", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int which) {
                    Log.d(TAG, " AGREE CLICKED"  );

                } }); 
      开发者_高级运维          alertDialog.setNegativeButton("DISAGREE", new DialogInterface.OnClickListener() {
                    public void onClick(DialogInterface dialog, int which) {
                        Log.d(TAG, " DISAGREE CLICKED"  );

                     } }); 
                alertDialog.show();

            }           
        }    
    }

A dialog needs an activity context. You have a service. Your options are:

  • Use a toast.
  • Create an activity and give it a Dialog theme.
  • There may be a third option to create or obtain a suitable context, but I'm not aware of one.
