the sensor data collection, when the Program interface exit (press the back key, or press the Home key ), the data will not be output. So I try to make the following simple changes, to achieve the ideal effect, so share here.The previous code was not modified:protected void OnStop () {super.onstop (); Sm.unregisterlistener (this);}Modified code (to achieve your desired effect):protected void OnStop () {super.onstop ();//sm.unregisterlistener (this); Comment out the line to ensure that the sens

Based on the tesseract of open source, we made an identity card recognition app.Picture Resources is Baidu looking for, and mobile phone to the computer screen to take pictures, shoot a lot of patterns, the impact is relatively large, so the error is not small, measured on their own identity card photo will be much better.：1.

Your Android project is very powerful, docking a lot of third-party open source libraries, the more complete the project, the more the code hit more and more cool. But suddenly one day the newspaper was abnormal.Error: The number of method references in a. dex file cannot exceed 64K.The compiler reminds you that your project has more than 64k of methods.Androidstudio will remind you:Learn how to resolve the issue at https://developer.android.com/tools

empty, the installation is unsuccessful.Preferexternal:The program is installed on the external storage media, but the system does not guarantee that the program will be installed on the external storage media, and when the external storage media is not available or empty, the program will be installed in memory. If the program uses the forward-locking mechanism, it will also be installed in memory because external storage does not support this mechanism. Once the program is installed, the user

You can use the ADB shell PM list PackageWe can use the System-provided tool pm to hide some applications, such as: PM Hide and PM DisablePM Disable (e.g. PM Disable "Package/class") (Disable the specified package, but the components of getcomponentenabledsetting the package are still enabled.)

, URI, file, resource ID, and so on. Basically meet most of the needs. Although loading local pictures is not as complex as network pictures, I recommend using glide to load local pictures. Because it is memory friendly, but also "secretly" to help us do a lot of things. For example, memory cache, bitmap multiplexing, fixed photo direction, and so on. Of course, in order to meet a variety of needs, just loading pictures is not enough, you also need to make a variety of images, that is, transform

Personally, it is to use the above method to decompile, the already written and generated Smali file into my package, and then in the manifest file configuration, and modify the package name, and finally RePack (to get this result is based on, I have two times packaged apk and another anti-compilation

Android share content to other applications, call System dialog or Actionbar pop-up windows are not too free, limited too much, here I provide a fully customizable interface, you can pop windows, or directly in the activity or fragment inside the custom interface. Here to show a key class of code, do the encapsulation processing, I write two demo, free source in: http://download.csdn.net/detail/yanzhenjie1003/8565449/** * @author YOLANDA * @Time April

Today in the use of 360 mobile phone assistant, found that it will automatically create a quick start mode, it feels very interesting, so on the Internet Baidu Some methods, try, there is a way is quite good, I use for reference, first save, I also wrote a Test applet.First, add the code in the mainactivity you want to launch the app into, and in the OnCreate () method, plus a method createshortcut ();Then there is the implementation of the method:private void CreateShortcut () {//TODO auto-gene

If the API or APK in the Android system is unable to read or write to the USB device, it may not be possible to add read/write USB permissions, which need to be set as follows:1. In the android.hardware.usb.host.xml file, add the following: name="Android.hardware.usb.host" /> 2. In tablet_core_hardware. Add the following content to the XML file name="Android.hardware.usb.host " > 3. Recompile the system.img, and burn the firmware to restart
