Android flash light app -


I want to make an app for Android device, which will have 2 buttons, one button for "ON" and another " Close ". I have done a pure search for an example and I have seen many examples, but they were very bad wars (for me). What I've created so far is the button and main activity code: 

  package com.simple.flashlight; Importroid.os.Bundle; Import android App Import android.graphics.Camera; Import android.hardware.Camera.Parameters; Import android.view.Menu; Import android.view.View; Import android.widget.Button; Public class increases main activity {@ Override Public Empty on Crate (Bundled Saved Instance) {super.onCreate (savedInstanceState); SetContentView (R.layout.main_menue); Button turnOnButtOn = (button) findViewById (R.id.button1); Button TurnOnButtOff = (button) Find ViewById (R.id.button2); TurnOnButtOn.setOnClickListener (New button. OnClickListener () {click on Public Zero (see Cambridge) {}}); }}   
 Now I want to do something (pseudo code):  
  turnOnButtOn.setOnClickListener (New button. OnClickListener () {public void onClick ( See the camera button) {turnOnTheFlahLight}}); TurnOnButtOn.setOnClickListener (New button. OnClickListener () {click on Public Zero (see camera button) {turnOffTheFlahLight}});   
 If there is a complete reference (I'm new to Android) then it would be nice. Thank you   
 
 
 Firstly, you need to add the permission of your manifest to use Flashlight:  
  ANDROID: name = "android.permission.FLASHLIGHT" Android: permissionGroup = "android.permission-group.HARDWARE_CONTROLS" Android: protectionLevel = "normal" />   
 Turn on the torch to do something like this:  
  camera mCam = Camera.open (); Parameter p = mCam.getParameters (); P.setFlashMode (Parameters.FLASH_MODE_TORCH); MCam.setParameters (P); MCam.startPreview ();   
 To turn it off:  
  mCam.stopPreview (); MCam.release ();

Python SQLAlchemy：AttributeError: Neither 'Column' object nor 'Comparator' object has an attribute 'schema' -

I tried to create a new database in my project, but when I run the script, I get this error, I have another project, this type of definition worked before, but now it gets a single error. I am using Python 2.7.8 and the version of SQLAlchemy module is 0.9.8. By the way, using a project flask- SQLAlchemy, it works well, I'm confused.

mongodb - CakePHP paginator ignoring order, but only for certain values -

While pagging my user model in kppp, I can sort with some values, but not others. For example, I can order results from created or email , for example, but username or reputation seems to come back order by arbitrary command for example with a list of users: $ this-> paginate = array ('condition' => array ( 'User.is_active' = & gt; true), 'border' => 24, 'order' => array ('User.created' => DESC)); Works as expected, but $ this - & gt; Paged = array ('conditions' = & gt; array (' user.isIactive '= & gt; true),' border '= & gt; 24,' command '= & gt; array (' user repeats' = ' & Gt; DESC ')); No, no. I first thought that this could be a database issue, but when I search the database directly, sorted as expected. Note: I am using Mangodebi with the Mongo DB plugin of Ichikawa for the KPPHP; Pagnetizing users are used to work properl...
