Load the jar plug-in Android app Introduction of plug-ins 1. Some custom general control code in the UI is not limited to a project. When shared use is required, you can integrate the source code into a new project, however, this original method increases the complexity of the Code layout and increases the security of general controls. 2. For some functional modules, third-party development, or phased devel

It is believed that the Android practitioner who walks over the steps, everyone will encounter oom situation. How to avoid and prevent the emergence of oom, for each programmer is indeed an essential ability. Let's talk today about the management of memory under the Android platform, and review the two concepts again before starting today's topic.

This is a smart way to do Android, according to the Linux cow (Copy on Write) theory, the n

I stumbled upon a strange phenomenon that day, and as I opened the page of our app, Memory monitor showed more and more RAM (the previous page had already be

Some resources should be rel

As a Java-based developer, it is easy to initially learn about Android development. Some of my colleagues are learning java, and I am interested in Android development, I started to learn about it and made a simple and practical small application in less than a month. There may be many people who will ask what are the gaps between Android Developers and those who

Android service resident memory: android residentWe always don't want our Android service to be cleaned up by the system. In the past, the most common method was to fork sub-processes in JNI and then monitor the service Process status, if it is killed by the system, restart it. I tested the LBE

1. Android Memory leakage Concept Many people think that JavaProgramBecause there is a garbage collection mechanism, there should be no memory leakage. In fact, if we no longer use an object in a program, but because there are still references pointing to it, the garbage collector cannot recycle it. Of course, the memory
