Receiver中启动两次Activity

1.广播接收者会启动两个CameaList

public class EzvizBroadcastReceiver extends BroadcastReceiver {
    private static final String TAG = "EzvizBroadcastReceiver";
    Intent toIntent =null;
    @Override
    public void onReceive(Context context, Intent intent) {
        String action = intent.getAction();
        if (action.equals(Constant.OAUTH_SUCCESS_ACTION)) {
            Log. e(TAG, "onReceive: OAUTH_SUCCESS_ACTION");
            toIntent = new Intent(context, CameraList.class);
            toIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            EZAccessToken token = MyApplication.getOpenSDK().getEZAccessToken();
            context.startActivity(toIntent);
        }
    }
}

2.解决办法为

1.intent添加flags
toIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
2.manifest 文件里面添加启动模式
<activity android:name="com.video.camera_list.CameraList" android:launchMode="singleTask" />
