I found that the display

The two architectures use different instruction sets, so it is necessary to use cross

action list of the target component's intentfilter, otherwise it cannot be matched; 1.2 If the type is not provided by intent, the system will get the data type from it. As with action, the data type list of the target component must contain the intent data type, otherwise it cannot be matched. 1.3 If the data in intent is not a content: type URI, and intent does not explicitly specify a type, the match will be based on the scheme of the data in the intent (for example, http: or mailto:). As

Deep analysis of Android's custom layoutsAs long as you have written the Android program, you must have used the Android platform built in several layouts--relativelayout, LinearLayout, Framelayout and so on. They can help us build the Android UI well.These built-in layouts already offer a lot of handy widgets, but in

This chapter focuses on the process of building Android's underlying development environment, including the Android application development environment, the ANDROIDNDK development environment, and the cross-compilation environment.1.

Java memory modelRelated Memory object model, refer to blog explaining Java memory model1) Register (register). This is the fastest save area, which is mainly because it is located inside the processor . However, the number of registers is very limited, so the register needs to be

This chapter mainly describes how to download and compile the Android source code and the Linux kernel source.1. Download, compile and test Android source codeConfigure the Android source code download environment:First step: Create a directory to hold the download script file (repo) (you can put the script file in any directory where you use ~/bin)# mkdir ~/bin#
