Another example if I now have activity A, B, C;Now I'm going to pass a value through a B to C.How do you pr
There is often a need to encapsulate your own modules or open classes into static libraries to provide convenient calls to others.But when you need to use a lot of xib, pictures, audio or other resource files in your module, you can't add them to the static library.

In Android development, you sometimes need to pass objects between applications or between processes, and here's a detailed description of how intent uses bundle to pass objects.
The object being passed needs to be serialized first, and there are two ways to serialize the object: Java.io.Serializable and Android.os.Parcelable

The difference between the two serialization m
The Android development environment is available in three different ways, Jdk+sdk+eclipse+adt, Jdk+adt-bundle, and Jdk+android Studio.Do not use Jdk+sdk+eclipse+adt this way, not to say what is too complicated, because the Guo Jia network you understand, open the SDK tool after the download is not.
