Question

我有这个例外：

java.lang.NoSuchMethodError: android.app.Notification$Builder.setProgress at android.support.v4.app.NotificationCompatIceCreamSandwich.a

这是我的GCMIntentService.java

      {
            int icon = R.drawable.ic_launcher;

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

            Intent notificationIntent = new Intent(context, ProblemioActivity.class);

            // set intent so it does not start a new activity
            notificationIntent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP | Intent.FLAG_ACTIVITY_SINGLE_TOP);
            PendingIntent intent = PendingIntent.getActivity(context, 0, notificationIntent, 0);        
            Uri defaultSound = RingtoneManager.getDefaultUri(RingtoneManager.TYPE_NOTIFICATION);            

             Notification notification = new NotificationCompat.Builder(context)
             .setContentTitle(title)
             .setContentText(message)
             .setContentIntent(intent)
             .setSmallIcon(icon)
             .setLights(Color.YELLOW, 1, 2)
             .setAutoCancel(true)
             .setSound(defaultSound)
             .build();

            notificationManager.notify(0, notification);
    }     
}

并且崩溃发生在这一行：

generateNotification(ctxt, extras.getString("message"), "New Message");

我应该用这样的方式包装那行：

if ( android.os.Build.VERSION.SDK_INT >= 8 )
{

}

在我的清单中，我允许所有这样的sdk版本：

Answer 1

为此提交了支持库错误，请参阅here。可以从this link中的comment #2下载固定的v4支持库。

Answer 2

这是在rev11之前android-support-v4.jar中的已知错误。

获取最新的android-support-v4.jar：

从IDE打开SDK Manager
选中Android Support Library，然后点击安装包
导航至yourSdkFolder/extras/android/support/v4并复制android-support-v4.jar
导航到项目中android-support-v4.jar的位置，然后粘贴，替换旧版本
