我正在尝试将推送通知发送到带有 GCM 的手机，它在带有 android 4 的设备上运行良好，但是当我尝试在 android 2.3 上发送通知时，应用程序崩溃了，我收到了这个错误

这是我的 GCMBaseIntentService 类

import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.util.Log;

import com.google.android.gcm.GCMBaseIntentService;

public class GCMIntentService extends GCMBaseIntentService {
    private static final String TAG = "GCMIntentService";
    PendingIntent contentIntent;

    public GCMIntentService() {
        super(GetObiecte.SENDER_ID);
    }

    @Override
    protected void onRegistered(Context context, String registrationId) {
        Log.i(TAG, "Device registered: regId = " + registrationId);
        Log.d("GCMIntentService", "in GCMIntentService");
    }

    @Override
    protected void onUnregistered(Context context, String registrationId) {
        Log.i(TAG, "Device unregistered");
    }

    @Override
    protected void onMessage(Context context, Intent intent) {
        Log.i(TAG, "Received message");
        String a = intent.getStringExtra("data");
        String b = intent.getStringExtra("data2");
        generateNotification(context, a,b);
    }

    @Override
    protected void onDeletedMessages(Context context, int total) {
        Log.i(TAG, "Received deleted messages notification");
    }

    @Override
    public void onError(Context context, String errorId) {
        Log.i(TAG, "Received error: " + errorId);
    }

    @Override
    protected boolean onRecoverableError(Context context, String errorId) {
        Log.i(TAG, "Received recoverable error: " + errorId);
        return super.onRecoverableError(context, errorId);
    }

    private void generateNotification(Context context, String message,
                                                String title) {

        NotificationManager notificationManager = (NotificationManager) context
                .getSystemService(NOTIFICATION_SERVICE);

        Notification notification = new Notification();
        notification.icon = R.drawable.ic_launcher;
        notification.tickerText = "i-Asigutare";
        notification.defaults = Notification.DEFAULT_ALL;
        notification.setLatestEventInfo(context, title, message, null);
        notificationManager.notify(0, notification);
    }
}

问题在于 notification.setLatestEventInfo 方法。

此方法在 API 级别 11中已弃用，鼓励使用Notification.Builder 。您还可以查看NotificationCompat.Builder以了解支持库的使用情况。

如果您仍然想按照自己的方式行事，您应该查看这个问题的公认答案： Android - 通知管理器，有一个没有意图的通知

这清楚地说明使用这样

notification.setLatestEventInfo(context, contentTitle, contentText, PendingIntent.getActivity(getApplicationContext(), 0, new Intent(), 0));

notification.setLatestEventInfo(context, title, message, null);而不是null您必须添加一个 Intent，当用户触摸通知时，它将启动。

从android 开发者页面：

contentIntent：当用户点击展开的通知时启动的意图。如果这是一个活动，它必须包含 FLAG_ACTIVITY_NEW_TASK 标志，这要求您按照任务和返回堆栈文档中的描述处理任务管理。
