-the-middle proxy technology, there is no need for a specific application or device to remotely run a compromised application even if the Android device has a full patch installed. Using static analysis we found that a significant percentage of applications are likely to remain fragile, and we have confirmed that more than half of the applications that have been randomized tested are indeed less resistant.Therefore, we recommend that you do not use an
I'm swype, slideit, and other brains from high-end Android input keyboards, but today I want to talk about solid keyboards consisting of various touch keys. Yes, it's the kind of physical keyboard. We used these bulky things before, and knocked out the next great masterpiece in a click. I never thought about using this to reply to text messages or emails, but when I decided to go to the cafe next to me and write something seriously, it would be nice t
How to determine files? You can use Cursor to traverse the database and compare the value of the INTERNAL_CONTENT_URI field. This is a Uri, which stores the complete path of the multimedia file on the Android mobile phone SD card.

binary translation, Intel Atom is able to execute programs that have been compiled on the ARM processor, but the performance is slightly lower than when the ARM processor executes, and this binary translation is not 100% fully compatible, Occasionally there will be no execution or execution to the halfway out of the situation.But don't assume that arm itself does not have a compatibility problem because ARM uses licensing, so the GPU parts of each processor are different, such as Qualcomm using
When we are working on a project, we need to consider the size of the image and the memory size when we encounter an image display. The reason is that the size allocated to Bitmap by Android is only 8 Mb, think about taking a photo on a mobile phone. A normal photo may not take more than 1 MB. Therefore, android has to consider memory exceptions caused by an exce

Use LRUCache, asynctask to achieve batch image loading and meet the following technical requirements1, read the picture from the cache, if not in the cache, open the asynchronous thread (asynctask) load the picture, and put into the cache2. Remove invalid asynchronous threads in time; Ensure that images are loaded asynchronously without ordering3, only the current screen visible part of the cache, loading pict
Android redmi solves the problem of reading images from local folders and obtaining paths,
In Android development, you can read images from local folders. Use the following code to open the image selection list:

Try to install the Qpython before, but it is based on python2.7. I am the python3 of study, so it has been useless. Today, I found the python3.2 version of Qpython3 in the Samsung App Store, so I'm here to share it with the Android guys.
The following is a partial screenshot of two software, which is fully functional.

dayThe Device Analyzer's data shows that the device's users open an average of 0.4-0.5 potential vulnerabilities per day. The average number of times a week has received (a vulnerability) attack. We cannot assume that the version of the app is newer than the one we have analyzed, so when our sample data is no longer the latest version, the corresponding graph also shows a sharp drop. If we re-performed our analysis of the latest APK version, we would probably see it still at 0.4 points. DA's da
resolution is constantly improving.So, as long as we try to match these resolutions, we can work on most phones.Of course, this is just the adaptation of the phone, for the tablet device (TV can also be seen as a tablet), we also need some other processing.Well, so far we've figured out why Android development is going to fit, and what we should be able to match, and then finally get to the point!First, we

Android displays RGB565 Data Images
I recently developed a project about video monitoring. I mainly used a Development Board to transmit the image data of one frame and one frame through a socket, then listen to the data on the Android client. After obtaining the data, it is displayed on the imageview. The core part is the problem solved after reading a post from

Sometimes, to display different images in the same ImageView, we often use:View plaincopy to clipboardprint?If (condition 1 ){Image. setBackground (R. id. xxx1 );} Else if (condition 2 ){Image. setBackground (R. id. xxx2 );}If (condition 1 ){Image. setBackground (R. id. xxx1 );} Else if (condition 2 ){Image. setBackground (R. id. xxx2 );} You can use another simple method to implement the same function.
