解析设备令牌为空

Question

错误：Device token 字段 always null 在 Parse Installation 表中。

代码

java

ParseInstallation.getCurrentInstallation().saveInBackground();
ParsePush.subscribeInBackground(AppConfig.PARSE_CHANNEL, new SaveCallback() {
        @Override
        public void done(ParseException e) {
            Log.e(TAG, "Successfully subscribed to Parse!");
        }
    });

有趣的事实是，如果在另一个项目中使用相同的 java 代码，它会生成 devicetoken。什么原因，没有为这个项目生成 devicetoken，明显的问题？有什么需要改变清单吗？请帮帮我。

Answer 1

您的软件包名称似乎是“com.dev.leapup”，但您在清单中错误地将其输入为“com.dev.leapup.pushnotifications”。

根据 Parse 的评论

<!--
  IMPORTANT: Change "com.parse.tutorials.pushnotifications.permission.C2D_MESSAGE" in the lines below
  to match your app's package name + ".permission.C2D_MESSAGE".

Answer 2

您应该安装 Google App 以在您的设备中拥有设备令牌... 它帮助我使用旧设备和 genymotion 模拟器....
