mainly study how to create sservicemanager objects. The following code creates an iservicemanager object: 1: sServiceManager = ServiceManagerNative.asInterface(BinderInternal.getContextObject()); First, let's look at the code of the getcontextobject method of the binderinternal class and find that it is the native generation.Code (haha! At the C/C ++ level, we are familiar with it.) The corresponding code is in android_util_binder.cpp.Android_ OS _binderinternal_getcontextobject function, th

Part 2 code verification The verification code for various image transformations described in the first section is as follows. A total of 10 cases are listed. To verify a specific situation, you only need to comment out the corresponding code. Images used in the test: Its size is 162x251. For the results of each transformation, see the description after the code. Package COM. pat. testtransformmatrix; import and
