If the navigation bar is applied and most of the activity's bottom navigation bar is the same, the navigation bar can be written as a generic module.4) ListView. Most applications use the ListView to show multiple data. The ListView style may often be adjusted later in the project, so it is better to use the ListView as a common module.

=null// execution time consuming memory operation, or call time consuming memory method ... } At this point it is necessary to assign the OBJ value to null to release the reference to the object as soon as possible. Try to cache frequently used objectsAs much as possible to cache objects that are used frequently, you can use arrays, or hashmap containers for caching, but this can cause the system to consume too much cache and degrade performance, and it is recommended to use some thir

Android App Optimizer (6) tool Chapter

This article introduces several tools for performance analysis on Android, all from the SDK, each strong enough for everyone to analyze and use.First, say TraceView.This tool in the SDK documentation is a bit more casual and probably says something about it. But the real need to use it to analyze the problem also requires a detailed understanding of how to use and quickly locate the problem.The following will be divided into four parts:The first is th

Run Zipalign on your application to make the interaction between Android and the application more efficient at run time. As a result, this approach allows applications and the entire system to run faster. We strongly recommend using the Zipalign tool on new and published programs t

replaced by the loaded view, and the View object is returned. This allows the application to get a reference to the load view without additional execution of Findviewbyid (). Experience Sharing:The viewstub can be associated with the layout resource file specified in the XML file, allowing the layout resource file to be loaded again when it is needed. When and when to load, without having to load at the start of the boot. Doing so can speed up application startup and save memory

Android Memory Optimizer 1 understanding Java GC Garbage Collection mechanism 1

能回收很少的对象,一般使用的是标记整理或者标记清除算法In the above way, the whole process of GC has reached the most efficient state.It is important to note the use of replication algorithms in the generational recovery algorithm.The previously mentioned replication algorithm is to divide the memory into two, but in the generational recycling is not so, but according to Eden:survivor A:survivor b= 8:1:1, the specific process is (simplified version):1.新创建一个对象,默认是分在Eden区域,当Eden区域内存不够的时候,会触发一次Minor GC(新生代回收),这次回收将存活的对象放到Surv

Android Memory Optimizer: Arraymap

does maketable do, as follows: Private hashmapentryWe clearly see that the new operation is done here and recreating the object is expensive.So arraymap, look at it. If the capacity is insufficient if (msize >= mhashes.length) { final int n = msize >= (base_size*2)? (Msize+ (msize>>1)) : (msize >= base_size?)

materials (instance) will cause the batch to fail. 7, objects with Lightmap contain additional (hidden) material attributes, such as lightmap offset and scaling coefficients. Therefore, objects that have lightmap will not be batched (unless they point to the same parts of Lightmap). 8, multichannel shader can interfere with batch operations. For example, almost all shaders in unity support multiple light sources in forward rendering and effectively open multiple channels for them. 9,
