这很简单,当你第一次在手机上使用解析时,它就像一个魅力.
当您重新安装应用程序时,它会拧紧所有内容.
当您重新安装应用程序时,它会拧紧所有内容.
如stackoverflow在Eran所述:
“PushService.subscribe似乎将订阅缓存在本地存储中,以避免在多次启动应用程序时重新订阅.
这是该方法的第一个参数用于:
context – 用于访问本地存储以缓存订阅,因此它当前必须是可行的上下文.
(引自here).
但是,卸载应用程序时,将从您的设备中删除该应用程序的本地存储,因此新安装将导致PushService.subscribe重新注册到Google Cloud Messaging.如果新注册返回新的注册ID,则Parse将具有两个注册ID,可用于向您的应用发送推送通知,并且它们都将链接到您提供给订阅的相同userName.因此,向该userName发送通知会将其发送到两个注册ID,导致它到达两次.
当Parse为您发送通知时,他们应该通过canonical_registration_id从Google获取回复,这会让他们知道您设备上与您的应用相关联的注册ID之一已过时,不应再使用了.因此(假设Parse有一个不错的GCM实现),下次你向设备发送通知时,你应该只收到一次.“
这是我的安装源代码:
String androidId = Secure.getString(getApplicationContext().getContentResolver(),Secure.ANDROID_ID); Parse.initialize(this,"KEY1","KEY2"); PushService.setDefaultPushCallback(this,ParseActivity.class); ParseInstallation installation = ParseInstallation.getCurrentInstallation(); installation.put("UniqueId",androidId); installation.setObjectId(null); installation.saveInBackground();

由于我没有找到任何真正的解决方案,我在这里问.
谢谢.
解决方法
我绝对相信这是由解析错误引起的.我在Parse.com找到的很多未解决的错误报告也说了同样的事情.
我目前正在使用Parse 1.5.1:
我看到的是没有deviceToken就不会发送推送,如果没有uniqueId,我们会在上面得到运行时错误.
如果我在注册后立即发送UniqueId,则会保存没有deviceToken的行.
在Nexus 5,Nexus 4和Sony xperia E上测试的解决方案:
在您的Application类onCreate()中

Parse.initialize(this,PARSE_APP_KEY_VALUE,PARSE_CLIENT_KEY_VALUE); PushService.setDefaultPushCallback(getApplicationContext(),MainActivity.class); final ParseInstallation installation = ParseInstallation.getCurrentInstallation(); final String androidId = Settings.Secure.getString(getApplicationContext().getContentResolver(),Settings.Secure.ANDROID_ID); // Post the uniqueId delayed Handler handler = new Handler(); handler.postDelayed(new Runnable() { @Override public void run() { installation.put("UniqueId",androidId); installation.saveInBackground(new SaveCallback() { @Override public void done(ParseException e) { // Saved! } }); } },10000 );
以这种方式工作,我能够保存正确的行(使用uniqueId和deviceToken),并发送推送通知!干杯!
