我正在尝试添加应用帐单并出错
Chech试用活动是我的启动活动，我正在尝试检查是否购买了此应用的用户， 这是我的ChechActivity：
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.trial);
SharedPreferences settings = getSharedPreferences(PREFS_NAME, 0);

settings.edit().putBoolean("my_first", false).commit();
}
Log.e("currenttime",String.valueOf(System.currentTimeMillis() / 1000));
Log.e("savedtime",String.valueOf(settings.getLong("time",System.currentTimeMillis() / 1000)));
if((System.currentTimeMillis() / 1000)-settings.getLong("time",System.currentTimeMillis() / 1000)>=43200){ /////////// trial time = 43200 seconds equal to 12 hours
settings.edit().putBoolean("trial",false).commit();
}
if (settings.getBoolean("trial", true)||settings.getBoolean("auth",false)) {
//// settings.getBoolean("trial", true) -----> trial time not expired //// settings.getBoolean("auth",false) ---> user email has regidtred on server

调用onCreate时调用checkAccount并发生错误
这是我的堆栈跟踪：

答案 0 :(得分：0)
启动IabHelper时，活动上下文可能尚未准备好。尝试使用应用程序上下文：
private void checkAccount() {
iabHelper = new IabHelper(getApplicationContext(), KEY);
...
}
