问题 I want to create an system application(while installing it will ask user permission to make it as system app) for UN-rooted application. As I am not familiar in android, please tell me how to create it. Thanks in advance. 回答1: True system apps are baked into the ROM image, and signed with the same key the ROM was signed with, giving them extra access to the system. You cannot add a new system app on the same level without updating the ROM image of the device, and even then you'll need the OEM

问题 How can I permanently change the PYTHONPATH on a mac? I've tried editing .bash_profile, but when I use print sys.path in a file it gives a huge list of different URLs than the .bash_profile. In Terminal when I type echo $PYTHONPATH it shows a blank line. I don't want to use sys.path.append('...') because then I have to put that in every file. 回答1: You can append the path to $PATH and not to $PYTHONPATH. if you insist to change the PYTHONPATH , in some context that is prefferable: do this:

问题 If have an enum in C#: [Serializable] public enum OperatingSystem { Windows, Macintosh } For my application I use the application settings, where I can select of which Type a setting should be.

问题 When I run tests I get the error "Command line is too long". It works if I set the "Shorten command line" method in the Run/Debug configuration to "JAR manifest" for the specific method or class, but how do I set it for the whole project or is there an IDE global setting for it? 回答1: You can set up a default way to shorten the command line and use it as a template for further configurations by changing the default JUnit Run/Debug Configuration template. Then all new Run/Debug configuration

问题 I'm making an application that should be used in a store that displays product information. I use an Android tablet to provide the customer with some interactive information. The user should not be able to do anything else with the tablet. So far i managed to disable the back and home button. The application starts when the booting of the device has finished.

问题 I have two MySQL instances. The 1st one truncates strings on insert when data is too long. The 2nd one raises an error: ERROR 1406 (22001): Data too long for column 'xxx' at row 1 I want the 2nd one to truncate the data as well. Is there any MySQL setting to manage this behavior? 回答1: You can disable STRICT_TRANS_TABLES and STRICT_ALL_TABLES . This allows the automatic truncation of the inserted string. Quote from MySQL Documantation. Strict mode controls how MySQL handles invalid or missing

问题 in an android app, if you create a new project, then automatically the 3 dot settings menu is created on phones where it is needed and it is handled the same way as it would have in older versions by: @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.activity_main, menu); return true; } if you create a custom title, you have to add the 3 dot menu yourself how do I know when it is needed? meaning phones that don't have the settings button also how do i
