Serial number is the same, device id from telephony is the same and now I discover that also Settings.Secure.ANDROID_ID is the same on each device. How Settings.Secure.ANDROID_ID is generated? 回答1: You can read this here http://developer.android.com/reference/android/provider/Settings.Secure.html#ANDROID_ID Android ID: A 64-bit number (as a hex string) that is randomly generated on the device's first boot and should remain constant for the lifetime of the device. (The value may

After doing a little research on the subject, on which there's hardly any valuable information online, all I understood is that this thread is supposed to unload the JVM upon exit . If that's the case, why is this thread in RUNNING state 100% of the time from the very first moment I start my application? Doesn't it consume valuable resources and therefore may cause an OutOfMemoryError (like I sometimes get)? Is there

The python debugger always show me this kind of error "timeout waiting for response on 113" I circle them in red in screencut. And I use Pycharm as my python IDE, is it just issue for Pycharm IDE? Or Python debugger issue? And if Pycharm is not recommended, can anyone give me better IDE which be able to debug efficiently. 回答1: I had a similar thing happen to me a few months ago, it turned out I had a really slow operation within a

By not working, I assume it's running before the stuff exists that it has to deal with. The Javascript is simply moving a div above another using insertBefore but this isn't always happening, and I assume it's because of when it's loading. My manifest is currently: { ... "content_scripts": [{ "matches": [ "*://example.com/*" ], "js": [ "js/jquery-1.8.3.min.js"

Apple also requires us to provide a server side mechanism to track the subscription with multiple devices. But, based on my research, apple also seems to reject app if registration is mandatory, so such user registration must be made optional. My app can be used without registration at start, so registering is optional at this point. But, if users want to buy non-renewing subscription, registration is mandatory to track the subscription.

It works, but I'm having a small issue with this hack. Since I'm using this technique to make secondary windows to my main application (popups etc), I need to set them on top of the main window. If I use the wrapper hack to do this, the top panel is "always on top" of everything (including other applications). Is there a way to put the secondary screen only on top of my application ? I don't like the fact that another application can be dragged

Using pgAdmin4 1.0-rc1 to connect to a local host "PostgreSQL 9.5.3, compiled by Visual C++ build 18..." I can connect and drill down to my schema. I use the context menu to select 'Query tool'.
