How to write an Android APP in PythonWriting Android apps using Python is definitely not the best choice, but it must be a very lazy choice and I really don't want to learn Java. Furthermore, as far as programming is concerned, there will already be Python and Golang (Note: Python and Golang are both at the normal level). After a long time, Google will be able to

There are a few things I have to do with the WiFi setting in boot (setupwizard,guide), such as the following:Intent Intent = new Intent (); Intent.setclassname ("Com.android.settings", "com.android.settings.wifi.WifiSetupActivity"); Intent.putextra (" FirstRun ", true); startactivity (intent);Suppose you need to add some of your own stuff to this WiFi setup interface, you need to write setup_preference this layout. For security reasons (changes will n

First we open our Android Studio. The setting page pops up and we select Show line numbers and click the OK button. Now we can see the travel number on the left side of the code. We can see that not only the Java code shows the line number, but also the XML code area shows the line number, you can try it yourself. Welcome to follow and will continue to write the series of

to open the program's own private files and data, you must use activity to provide openfileoutput and Openfileinput methods.To create a file that is private to the program, you must use the Android read-write file method provided by activity due to permission requirements FileOutputStream OS = this.openfileoutput ("Android.txt", mode_private); Outpu

/EEPROM Package, burn the firmware to the Development Board, and start the application to view the icon. Summary: The entire call process is: app One problem is that this method changes the android native API. After all, it accesses the hardware. If you want to make a general app and want to use C/C ++ to improve efficiency, you can directly develop the ndk and compile the function into library files into the app project. Another problem is hardware

We can usually set the margin directly in XML, such as:android:layout_margin= "5dip" android:src= "@drawable/image" />However, in some cases, it is necessary to write in Java code, but the view itself does not have a setmargin method, how to do?By looking at the Android API, we found that Android.view.ViewGroup.MarginLayoutParams has a method SetMargins (left, top, right, bottom).Its direct subclasses are

The following is the transparency statement for your reference. Not transparent 100% F

Come on, let's write an IOC framework for Android !, Androidioc framework Currently, the afinal development framework has been in use for several months. Remember the first time you used annotations to initialize controls and bind events, how excited I was at that time-the code could be written like this! Then, as I continue to learn, I have gradually gained a simple understanding of the IOC framework, anno

There are some WiFi settings in boot (setupwizard,guide), and I'll do the following:Intent Intent = new Intent (); Intent.setclassname ("Com.android.settings", "com.android.settings.wifi.WifiSetupActivity"); Intent.putextra (" FirstRun ", false); startactivity (intent);If you need to add some of your stuff to this WiFi setup, you need to write the layout of setup_preference.
