Android Call so The Android virtual machine cannot call the underlying device directly, and we need to use so if we want to call the underlying device. So use C language or C + + writing complete, using NDK to compile, run directly in the Linux kernel. By JNI call So when the basic type can be directly interactive, jstring use a bit cumbersome, so I do a jstring and char* to convert the example. First ste

This article is an example of the Android implementation of the URI to get the real path into file method. Share to everyone for your reference. The implementation methods are as follows: Uri uri = Data.getdata (); String[] proj = {MediaStore.Images.Media.DATA}; Cursor actualimagecursor = Managedquery (uri,proj,null,null,null); int actual_image_column_index = Actualimagecursor.getcolumnindexorthrow (Me

When Android calls the system to crop data without returning data, the file modification time is used to determine whether the user has cut or not. The android modification time Some mobile phone prompts that the content cannot be greater than 40 kb if you set the image to be returned when you call the cropping system for a company project ), therefore, you need

re-mount the system partition to make the system partition writable. If you do not execute this operation, you cannot modify the build. prop file. Adb remount (2) Next, enter the command line of the simulator: adb shell (3) write the configuration to build. prop: echo "dalvik. vm. dexopt-flags = v = n, o = v ">/system/build. propecho "dalvik. vm. checkjni = false ">/system/build. in this way, the prop is changed to the simulator. After verification,

A lot of times we're sensitive. Google follows a large number of MVC architectures when designing Android, allowing it to be independent of writing public code, artwork, and concrete logic developers. How do you implement a formatted string in the Android resource file Values/strings.xml? Here's a simple example of Android123, and where you might end up using it.
