how to send large files from android

1:android development, it is inseparable from the operation of the file, because the file can store a large amount of data, mastering the relevant technology can bring a lot of convenience for development, is our application in the mobile phone or simulator on the internal storage location.2: Through a simple program to achieve the Android application of internal

Android storage learning: Reading and Writing files in External Storage This section describes how to read and write files in the internal storage of a mobile phone. That is how to read and write files in Sdcard. The previous logon interface is used as an example to illustrate how to read and write

in order to better in response to network access, recently learned a bit okhttp, feel very convenient to use, first to use okhttp, need to import Okhttp-x.x.x.jar in the project Okhttputils-x_x_x.jar Okio-x.x.x.jar These three jar packages, the following is the Android side and server-side key code: private void Uplodeimage (file mfile) {//mfile A real existing picture file if (!mfile.exists ()) { Toast.maketext ( Mainactivity.th

When using WebView to load Web pages, there are some fixed resource files such as JS jquery package, CSS, pictures and other resources will be relatively large, if directly from the network loading will cause the page to load relatively slow, and will consume more traffic. So these files should be in assets and packaged with the app.To solve this problem, you nee

In Android, cross-process communication is a very common thing, it uses the binder mechanism to process the interaction between processes. The binder mechanism will open up some interfaces to the Java layer for the Android developer to communicate between processes. These interfaces are packaged into the Aidl file, and when our project is used for cross-process communication, the. aidl file can be created,

[Android] does not display the generated image files in the system Gallery.I encountered a problem before, that is, after I generated a new Bitmap in the program, I did not see the new image when I opened the system's Gallery view. However, open the file browser, find the folder where the Bitmap is saved, and you can see the Bitmap file generated by the program. That is to say, the file actually exists, but

Now smartphones (the mobile phones in the broad sense, including mobile devices such as mobile phones, tablets, etc.) are becoming more and more important in life, people use mobile phones much more than computers, because of the portability of mobile phones, so many times we will need to use mobile phone to carry data or files, or for entertainment. For example, when riding a train or a car, to see a movie with a mobile phone is quite good, now the p

Frequent thread object creation may also consume a lot of performance.After testing the above Code, a large number of concurrent logs can be written in multiple threads, which ensures that logs are written to f
