Show dialog in broadcast receiver

I read other posts and I understood I can do it in broadcast class so I created other Activity, but it crashed. In

logcat
error is on this line
context.startActivity(intent1);


my Broadcast

private final BroadcastReceiver receiver = new BroadcastReceiver() {
@Override
public void onReceive(Context context, Intent intent) {

String action = intent.getAction();

if (action.equals("android.intent.action.BATTERY_CHANGED")) {



Intent intent1 = new Intent(context.getApplicationContext(),BatteryDialog.class);
intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(intent1);



}

}
};


BatteryDialog.java

public class BatteryDialog extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

final Dialog dialog = new Dialog(BatteryDialog.this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.cooler_guide_dialog);
TextView textViewGuide = (TextView) dialog.findViewById(R.id.textViewGuide);
Button buttonOkDialog = (Button) dialog.findViewById(R.id.buttonOkDialog);
textViewGuide.setText("Text");
buttonOkDialog.setText("Button");
buttonOkDialog.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {

dialog.dismiss();
}
});
dialog.show();
}}

You should declare all your activities in AndroidManifest.xml before using them as Intent. Place the activity BatteryDialog in the Android manifest properly.

Try something like this:

<activity android:name= ".BatteryDialog" />
