在 GcmListenerService 中获取错误

Question

有时在收到任何推送通知时出现此错误（并非在每台设备中）——这可能是设备问题？？最近在 Android 5.0

中崩溃

请帮忙!!

我正在使用这个代码：

public class MyGcmListenerService extends GcmListenerService {
private static final String TAG = "MyGcmListenerService";
private Intent intent;
@Override
public void onMessageReceived(String from, Bundle data) {
    Log.e("onMessageReceived", "onMessageReceived:" + data.toString());
    Utils pref = Utils.getInstance(getApplicationContext());
    String uid = pref.getString(Constants.uid, "");
    if (uid.length() > 0) {
        if (pref.getBoolean(Constants.isEnableNotification, false)) {

            try {
                String response = data.getString("data");
                if (response != null) {
                    JSONObject jsonObject = new JSONObject(response);
                    if (jsonObject.has("stype")) {
                        String stype = jsonObject.getString("stype");
                        if (stype.equalsIgnoreCase("timeline")) {

                            String message = msg.trim();

    NotificationManager notificationManager =

    notificationManager.notify(0 , notificationBuilder.build());

Answer 1

int uniqueInt = (int) (System.currentTimeMillis() & 0xfffffff);

而不是给 0，

 PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent,PendingIntent.FLAG_UPDATE_CURRENT);

给那个 uniqueint
