In the setings/about phone of the Android device, the option model number exists, for example: Click "about phone" to view the model number. OK. The summary of model number is the SDK. How does Android determine this value? How can we modify this value? In COM. Android. settings. deviceinfosettings. Java, the cod

If you select "Use same device for future launches" for Android App debugging in Eclipse, you will no longer be able to select other devices. androidlaunches After a vendor's multimedia control App is so bad, I want to do it in minutes. Of course, it is hard to do it. We are confident that we will surpass their bad software. Various pitfalls encountered during the process, one of which is as follows: At t

I checked a lot of information and many people mistakenly thought it was the/dev/yourdevice created by the kernel. In the latest kernel, this statement is incorrect. In fact, the kernel is only responsible for creating a large number of directories and files in/sys, The real device nodes are created in the user space. In the Android system, the INIT process is responsible for processing such uevent event

method One:Returns the Android Device ID as a unique 64-bit hexadecimal string.import android.provider.Settings.Secure;private String android_id = Secure.getString(getContext().getContentResolver(), Secure.ANDROID_ID); Method Two:The UUID is a 128-bit globally unique, immutable identifier (UUID).import java.util.UUID;privatestatic String uniqueID = UUID.randomUUI

Suppose the API or APK in the Android system cannot read and write to the USB device. may not be added to read and write USB permissions, you need to follow such as the following methods to set up:1. Include the following in the android.hardware.usb.host.xml file, for example name="android.hardware.usb.host"/> 2. In tablet_core_hardware. XML file, such as the following : name="Android.hardware.us

To solve the Android device fragmentation, introduce a concept density, that is, density. It refers to the number of pixels displayed on a physical screen of a certain size, generally using the dpi (dots per inch, pixel of each inch) as a single such as the device resolution of 240x320, screen physical size of 1.5 inches x2 inches (Diagonal 2.5) Its density can

AID conflicts. The payment class is made by setting the default app, while the other class is the UI popup selection prompt.4. When the screen is off, HCE is not available, the screen is locked HCE can choose support, or you can choose to prompt the user to unlock and then support.5. In the case of the terminal only HCE no SE, ISO 14443-3 of the non-connected parameters by Android takeover, UID use random number, do not use HCE to implement any UID-b

The Android system will first read the value of the btm_def_local_name, and if it is empty, use "Ro.product.model" as the Bluetooth device name.system/bt/btif/src/btif_dm.cc#define PROPERTY_PRODUCT_MODEL "ro.product.model"......static char* btif_get_default_local_name() { if (btif_default_local_name[0] == '\0') { int max_len = sizeof(btif_default_local_name) - 1; if (BTM_DEF_LOCAL_NAME[0] != '\0') {

One. Connect the Android device to the computer and install the associated driver. Two. Set the user's environment variable. "My Computer"-->> "Properties"-->> "Advanced"-->> "Administrator's user environment variable"-->> "Path" Click on the "Edit" button, at the end of the "Variable Value" column, enter the absolute path of the platform-tools and tools under our Installation SDK directory, in the middl

/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
