无法在 Android 中取消注册 GCM

【中文标题】无法在 Android 中取消注册 GCM

【英文标题】：Unable to unregister GCM in Android

【问题描述】：

当用户注销时，我正在尝试注销GCM。我正在使用以下代码来执行此操作。

public void logout()

        GoogleCloudMessaging gcm = GoogleCloudMessaging.getInstance(NewSettings.this);
        try 
            gcm.unregister();
         catch (IOException e) 
            e.printStackTrace();
            e.toString();
            Toast.makeText(NewSettings.this,"Problem in logout, try again later!",Toast.LENGTH_LONG).show();
        

这不会取消注册 GCM，因为我在 logcat 中遇到了一个异常，就像这样

文档提到

所以我也尝试使用这个

 public void logout()

        InstanceID instanceID  = InstanceID.getInstance(NewSettings.this);
        try 
            instanceID.deleteInstanceID();
         catch (IOException e) 
            e.printStackTrace();
            e.toString();
            Toast.makeText(NewSettings.this,"Problem in logout, try again later!",Toast.LENGTH_LONG).show();
        

我仍然在 logcat 中得到这个

我是否以正确的方式取消注册GCM？请让我知道如何实现它。提前致谢。

【问题讨论】：

您可以在AsyncTask 中运行unregister，参见this

【参考方案1】：

我需要在新线程中运行它。这解决了我的问题。 谢谢@calvinfly。

public void logout()

        instanceID  = InstanceID.getInstance(NewSettings.this);

        Thread thread = new Thread(new Runnable() 
            @Override
            public void run() 
                try 
                    instanceID.deleteInstanceID();
                 catch (Exception bug) 
                    bug.printStackTrace();
                

            
        );
        thread.start();

【参考方案2】：

尝试取消注册 GCM。 GCMRegistrar.unregister(getApplicationContext());

【讨论】：

gcm.unregister() 已于 2015 年 5 月 28 日弃用。
