running out of memory and does not cause memory overflow. And when memory resources are plentiful, these cached data can exist for quite a long time.Four, virtual reference A virtual reference is the weakest of all reference types. An object that holds a virtual reference is almost the same as no reference, and can be reclaimed by the garbage collector at any time. When you try to get a strong reference by a virtual reference, the Get () method always fails. Also, a virtual reference m

if you read the pictures from the hard disk each time, it can severely affect performance, but if you load all of your memory and potentially cause a memory overflow, using a soft reference can solve the problem. The design idea is: With a hashmap to save the picture path and the corresponding Picture object associated soft reference between the mapping relationship, in the memory is not enough, the JVM w

In non-full screen mode, set the activity's windowSoftInputMode attribute to adjustResize. At the same time, you can get the changed size in onSizeChanged (int w, int h, int oldw, int oldh) of the View, and then calculate the distance to move the screen based on the results of the changes. However, in full screen mode, even if the activity's windowSoftInputMode attribute is set to adjustResize. When displayed on the keyboard, the Screen of the Activity is not pushed up, so the size of the

Normally, objects with soft references are not recycled when the memory is sufficient. The Java. Lang. Ref package provides several classes: softreference class, weakreference class, And phantomreference class, which represent soft refere

virtual machine adds the weak reference to the reference queue associated with it if the object referenced by the weak reference is garbage collected. The fundamental difference between weak references and soft references is that objects with only weak references have a shorter lifecycle and may be recycled at any time. Objects that only have soft references are recycled only when there is not enough memo

[Hardware_vendor], such as TI's decoder is the beginning of omx.ti. Of course, there are some non-compliance with this naming convention, not to OMX, it will also be considered a soft decoder.Judging rules See F

Android solves the problem of massive image downloads: Soft references must be understood as 4 points, 1. Strong, soft, weak, and virtual references of ObjectsIn order to control the lifecycle of objects more flexibly, you need to know the level 4 of object reference, from high to low: strong reference, soft reference,
