[Android] Share based on Qt and I made a small program

GLSL This is my first contribution to the times ......
Regardless , this time to tell you about is that I made ​​based on Qt and GLSL shader applet. We all know that if they produce a shader editor, time-consuming , but fortunately for OpenGL Qt provides a good package, so you can use Qt -based entry-level write powerful applications. Do not believe look:

can write shaders GLSL produced by my editor ( supports syntax highlighting ) .

Here is what I use to complete the gray shader effects :

This is the shader code :

we can try .
Here is what I wrote the blog , you can stroll around more than a look .
based on Qt and GLSL shader examples < / span>

If you have git, you can also try to look into the local clone . I created a code repository on gitorious.

[Android] QSound problems playing sounds

I created a Qt quick project , which use QSound play a sound,
Now the sound files into the resources qrc file.
calling the following code

  QSound sound(":sound/testsound.mp3");
          sound.play();
  

only beep once , did not play a sound file .
I checked the path is not wrong , how to modify how it can play a sound ? ?
------ Solution ---------------------------------------- ----
QSound does not support resource files

only play files on disk .
------ Solution ---------------------------------------- ----


should support it.

problem here is QSound does not support mp3 format file playback .
document is described:
Microsoft Windows The underlying multimedia system is used; only WAVE format sound files are supported.
X11 The Network Audio System is used if available, otherwise all operations work silently. NAS supports WAVE and AU files.
Mac OS X NSSound is used. All formats that NSSound supports, including QuickTime formats, are supported by Qt for Mac OS ; X.
Qt for Embedded Linux A built-in mixing sound server is used, accessing / dev / dsp directly. Only the WAVE format is supported.
Symbian CMdaAudioPlayerUtility is used. All formats that Symbian OS or devices support are supported also by Qt.

landlord can try to sound resource converted to wav format to use. If you must use the mp3 on the use of other types of bars , QSound not do

Before
I can not play with the absolute path , issued only beep is heard .

[Android] OpenGL ES2.0 in onDrawFrame drawing with thread you?

RT, I want to set a thread after each call Thread.sleep unfinished (20 ) to allow the thread to sleep
then continue painting until it is fully completed matrix transformations , to enlarge the animation effect .
but the program has been a crash , so my idea of code impress , seeking Great God Guidelines

  public void onDrawFrame(GL10 gl){
      GLES20.glClear(GLES20.GL_DEPTH_BUFFER_BIT|GLES20.COLOR_BUFFER_BIT)
      Thread Trans_Thread = new Thread(){

            public void run(){
                 boolean flag = true;
                 while(flag){
                     画四个图标
                     for(int i=0;i<4;i++){
                         //所有矩阵的定义和操作都放在了MatrixState.java里，纯方法实现
                         //矩阵平移，以便图标一字铺开。
                         MatrixState.translate(i*2f,0,0)
                         //被聚焦的图标会有动画放大的效果
                         if(FocusPosition == i){
                                //进行矩阵缩放，即图标缩放
                               MatrixState.scale(1.3f/50,1.3f/50,1.3f/50);
                         }
                         //Square类的绘制函数
                         Square.drawSelf();   
                     }
                     //判定是否已经缩放完成
                     zMove = zMove + 1.3f/50;
                     //运行标志设为false
                     if(zMove>=1.3f) flag = false;
                     try(Thread.sleep(20);)catch(Exception e){System.out.println(e);}
                 }
            }
      }
      Trans_Thread.start();
  }
  

In the absence of additional threads can be stable drawing , but did not focus on the enlarged icon animation .
Great God seek advice
------ Solution --------------------------------- -----------
I think the thread should be placed outside onDrawFrame, then postInvalidate () to inform the system update
------ eference -------- -------------------------------

thanks, buddy, this problem has been solved. Because onDrawFrame function itself is constantly refreshed, as long as the appropriate control parameters can be in it . Your reply this point be rewarded .

[Android] [Share] phonegap push- message push to achieve

Recently been studying a variety of push , ios due to be apns, relatively easy to implement, but andriod more trouble . After reading many solutions , gcm obviously does not work, other options is confused , but needs to be done to develop the second time , too much trouble , and later choose to use third-party services to achieve a push .

currently do have a good push and Aurora .

a push optimal but need to pay . For us this little app, simply can not cope , then decisively choose Aurora .

The following are my phonegap sdk integration process with the aurora .

  1. registered aurora developer account , and register the application information .

create an account after entering the aurora push platform , the first application of the display is to create an interface . Fill in your application name, and the name of this two Android package on it.


with creating successful , enter " Application Details " display. The lower right corner of the interface , you can see behind "appkey" will be used .

  2, download the sdk package. Line integration

specific processes can be seen following documents , of course phonegap integration and this is somewhat different.

http://docs.jpush.cn/pages/viewpage.action?pageId=557214

  3.SDK integration steps

1, import the SDK development kit to your own application project

decompress jpush-sdk_v1.xyzip integrated archive
copied to the project under libs/jpush-sdk-release1.xyjar libs / directory
copy libs/armeabi/libsys1.xyso to the project libs / armeabi directory ( if your project has libs/armeabi-v7a this directory, please libsys1.xyso also copy to this directory )

demand note here is: import into the package after package must take configuer building path.
2, Configuration AndroidManifest.xml

According compressed bag AndroidManifest.xml SDK sample files to configure AndroidManifest.xml application project .

The main steps are:

copy notes as "Required" part
replace the notes as part of the package name , replacing the current package name of the application
Replace the AppKey registered on the Portal of Key applications, such as (9fed5bcb7b9b87413678c407)






package = "Your Package"

android: versionCode = "100"

android: versionName = "1.0.0"

<-!. Required AppKey copied from Portal ->









It should be noted that: some had previously been added xml information , this time to eleven control this inside information a one added.

Note the order :




3, add the code

JPush SDK API interfaces provided are mainly concentrated in the cn.jpush.android.api.JPushInterface class.

accordance with the following methods to modify :



4, tests confirm

confirm the required permissions have been added . If permission is not necessary to add, log an error .
confirm AppKey ( on the Portal generated ) is correctly written Androidmanifest.xml.
recognized in the program start time to call the init (context) Interface
confirmation test phone ( or emulator ) has been successfully connected to the network
client shortly after the call init , if all goes well , there should be a successful login log information
start the application , the Portal to send a custom message or prompt notification bar to the application . Please refer to the Management Portal.
within a few seconds , the client should be notified under the definition of a message being sent or

If the SDK is working properly , the log information is as follows:

As shown, the client initiates divided into four steps :

check the metadata of appKey and channel, and if not, then failed to start effectiveness
initialization JPush SDK, check the JNI library files , etc. , if the library file is invalid , then failed to start
check Androidmanifest.xml, if you have permission Required does not exist , then failed to start
connect to the server login, if there is a network problem, login fails, or three steps in front of a problem , do not start JPush SDK


As long as the test is successful , ok, you can go to manage Portal, to send the information. No accident, then , will be able to receive the information .

Of course, this is just a simple push messaging features , some of the specific application , you can then refer to the official api documentation to their development .

On Android, because Google's own Android standard implementation GCM (Google Cloud Messaging, originally called C2DM) basically unavailable in the country , so , for developers , if necessary Push function , how to choose to become a problem.

So far, there is not yet completely free to developers and open Push service is available. There are several third-party push services abroad , but generally should be charged . So, in general , the domestic developers have to consider yourself to build Push services.

build their own Push service, a more natural choice is based on open source solutions do now .

use Google or Baidu search "Android Push Push " and other words , show that there are a lot of people have been studied . The top edge is such articles :

Android push way to achieve solutions
push to achieve with androidpn Push on to achieve
Android
Android Push Notification using information push to achieve

article mentioned above scheme, basically referred to an open source Android Push to achieve : androidpn .

androidpn it is essentially based on the server side Openfire , client -based asmack, which both open source implementation of the XMPP IM in the two basic components , it should be said ; androidpn just two more combine to make Push the scene .

I did chat App, here are willing to put practical experience doing open source XMPP -based IM system to others.

We do chat class App, more natural way , starting from the beginning is also open source XMPP IM systems research .

said first server-side options. Openfire is one of the oldest open source XMPP IM Server, do almost all the IM should have studied . However , it is also applied to the production of the most inopportune IM Server, because : single concurrency is very limited, cluster programs mature, old code and the lack of timely updates . For a concrete example : Openfire cluster assembly called Connection Manager , but you can see in the Openfire official website , the most recent version was released in February 2009 . Visible, based Openfire achieve androidpn is not enough to stabilize the foundation .

Update : App -based chat Openfire do communicate with a friend , their users than the larger, multiple Openfire cluster nodes do . Openfire they do a lot of transformation, such as XMPP protocol interaction complex , to simplify ; XMPP protocol text bloated , then converted to binary . Cluster is concerned, is entirely their own re- development. They load up to 300,000 users a single point .

In fact, relatively little has another two good options: ejabberd , tigase . ejabberd is using Erlang language, understand Erlang users rarely , it is generally not vote . We had a preliminary chat server option is tigase (Java implementation ) .

tigase authors maintain very active , the test results can be clustered to support a relatively large capacity, which is to attract our place. But after actual production operations point of view, because of its cluster program implementation complexity , as well as single- node capacity is limited, we do not have confidence in the 500,000 users on the cluster nodes to support , so the reach 500,000 before users , quickly developed its own alternative.

again for XMPP protocol with the client 's question: For mobile clients , the original XMPP somewhat complicated and traffic consumption . XMPP protocol is essentially the structure of the body are in the xml string , the amount of each agreement are a bunch of string , xml where there are a lot of meaningless structure. In addition , XMPP for its flexibility , you need to log in this matter there are N and forth . For mobile client care about traffic and capacity for , XMPP relatively bulky.

Our approach is : the agreement to a binary format , simplifying interaction on the agreement, but retained the original XMPP compatible .

androidpn Push is open source implementation is based on the XMPP open source components integrated, it does not make the necessary optimized for mobile application scenarios. In addition , XMPP IM is essentially a two-way agreement, and to achieve a direct XMPP -based Push function is not specifically optimized for Push features , such as client network strategies connections.

summarize in androidpn typical open-source Android Push program there will be a problem :

1) open source server implementation capacity stand , still need to improve their own open source implementation of new programs or completely re- use , high cost of investment and development is inevitable .

2) the agreement and implementation of such traffic consumption , network connectivity strategies , not specifically optimized for mobile Push is not economical.

our team based on the open source XMPP chat App system implementation experience , we have come to the conclusion that, in the IM client moving scenes , the open-source program is not an easy solution available . Later we own a complete re- architecture of the whole system . After that, this new architecture is based IM system , evolved out of the aurora push.

[Android] listview nested gridview, how to determine the point of the picture is still blank gridview part

My listview nested gridview, gridview is only one long picture , I click on the picture is enlarged , but I actually click on a blank part of the side or click on the picture , I did not write girdview of OnTouch event , only the onclickitem click event , how to listen , when you click a blank part of the item rather than responding to gridview listview 's item event . .

this is a positive solution !

you say is not in eclipse in DDMS file explorer?
If so, first ensure that the emulator is started or connected via usb debugging real machine
you can see the
If you still do not see , use the following steps
system / system / bin which can be found no ls file, so can not call file explorer in DDMS
solution:
1. In Eclipse open inside the simulator , through the simulator DDMS-> file explorer find / system / bin, export toolbox replace real machine files in the same directory (you may need ROOT explorer software )
2. Ls to make a name in the real machine / system / bin file to point connection toolbox. Under
linux commands can be directly used Link
mobile terminal open root explorer, find the same connection file a pointer toolbox in / system / bin, such as cat, copy , rename ls can !

[Android] Inherit two application

I now have a third-party package needs to import , import and my example no problem running, but imported into the program discovered the problem , logcat print out the error java.lang.ExceptionInInitializerError, the Internet is said in the calculation of the initial value of a static or an exception occurs during the initial value of a static variable , through my observation , it is estimated that a third party needs to inherit the bag comes with application, application example is the direct successor to the third-party package , up and running no problem , but I now have program an application , I want to how to merge these two application? also, or there are other solutions , the novice neighborhoods ah

[Android] qt part of the text can not be achieved in a dynamic language switching

In his qt project has both English and Chinese languages ​​can be switched at any time , but now found that some text can not be switched into Chinese . For example, the following code :
MainWindow :: MainWindow (QWidget * parent):
QMainWindow (parent),
ui (new Ui :: MainWindow)
{
ui-> setupUi (this);

QTranslator trans;
trans.load ("gui_zh");
QApplication :: installTranslator (& trans);
ui-> retranslateUi (this);
}

MainWindow :: ~ MainWindow ()
{
delete ui;
}

void MainWindow :: on_pushButton_clicked ()
{
QString fileName = QFileDialog :: getOpenFileName (this, tr ("open"), QDir :: currentPath (), "* . cpp ");
}

The red part is to open a dialog box to get the path to a file , "open" is how the string are not a Chinese translation , such examples in my project there are many, who can tell me this is how things , there is no solution ?
Note: I have generated the specified qm file
------ Solution -------------------------. -------------------
first you write or translate a document class file must have Q_OBJECT, first make sure your *. qm files which are English translation of all the best to your translation files (*. qm) joined the program resource file , and then add in the main program
QTranslator * translator = new QTranslator (0);
translator-> load (":/ * qm.");
QApplication object using the call app
app.installTranslator (translator);
I hope to help you

----- - eference ---------------------------------------
their first top
------ eference - --------------------------------------
your question is not very clear .
first load did not translate ? After the switch is in English, the switch did not translate over time ?
I feel the possibility of a second relatively large .

when switching languages. Sends LanguageChange events.
generally when handling this event . ui-> retranslateUi (this); Ui interface will be re- translated.
but tr function inside part of the program before you call may fail .
You have to re-set inside LanguageChange events.
------ eference --------------------------------------- < br> Also in check there is no such Q_OBJECT.
------ eference --------------------------------------- < br>

class there Q_OBJECT, after running the software will load the translation file , then the translation part is normal, but for example, the code inside the red phrase "open" string was not a Chinese translation , not what you say second , re-set in which you say LanguageChange event , which function in this what you want to set , how to set up , please let us know !
------ eference --------------------------------------- < br> you this question , really did not come across. Are you sure you qm translation ?
You can try to print QApplication :: translate ("MainWindow", "open", 0, QApplication :: UnicodeUTF8)
look is not Chinese ?
if not Chinese . Qm explain your problem , there is no translation .
------ eference --------------------------------------- < br>

or not, do not know if my computer problems, try to go home with a laptop , you do not come across this question, in my project this problem many ah
------ eference - --------------------------------------
if QApplication :: translate (" ; MainWindow "," open ", 0, QApplication :: UnicodeUTF8) this is the English words.
That is your translation problem.
look ts and qm it.
