algorithms, so as to exchange variables. That is:
int *a,*b;
A = new int (10); // assign a value to the pointer
b=new int(20); //a=0x00030828,b=0x00030840
a=(int*)(b-a); //a=0x00000006
b=(int*)(b-int(a)); //b=0x00030828
a=(int*)(b+int(a)); //a=0x00030840
Note: In the last three sentences, only the first sentence is the calculation between two pointers, and the other is the calculation of pointers and integers. Otherwise, the calculation will be wr

compile. You can analyze the source code of the released library or execution file directly and generate an assembly file using objdump, through the corresponding address, you can find out which function has a problem. As for the guessed code, you need to build a unit test based on the analysis situation or re-launch the code for testing.
Specific process examples are as follows:Objectdump-d ##. so >##. oVim ##. o6 libTaps2.so + 0xa452d

As described in the android documentation, the SDK level (integer) the phone is running is available in:Android. OS. Build. VERSION. SDK_INT;The enum corresponding to this int is in the android. OS. Build. VERSION_CODES class.
Code example:Int currentapiVersion = android. OS. Build. VERSION. SDK_INT;If (currentapiVersion> = android. OS. Build. VERSION_CODES.FROYO ){// Do something} Else {// Do something}
Note:This SDK_INT is available since Donut (android 1.6/API4)So make sure your application i
address, it needs to be read twice, after reading the data, you must splice the memory content to obtain the short variable. If it is stored at the address B = 0x0000002, you only need to read it once and do not need to splice the memory content. Then the variable c starts to be stored after B. The address is 0x00000004, but it only occupies one byte. Similarly, the remaining space cannot be used for storage, however, since the processor reads data from even bytes, why is the starting address o
