Long time no blog, because a moment of laziness and forget the update, today to say that the Android APK compilation and packaging processThe first step of the APK package is to first compile the resource file and the manifest fileThe second step is to compile the. java in SRC into multiple. class files, and then compile all the. class files into a. dex file that the DVM can run.Although it seems to me that my blog may be very short-sighted in front o

means that only 64m of memory is actually used while the program is running, and Oom is reported beyond. (Only for Dalvik heap, not including native heap)The Dalvik.vm.heapsize=384m//heapsize parameter represents the maximum amount of memory available to a single process, but if there is a heapgrowthlimit parameter, the Heapgrowthlimit is the standard.HeapSize represents an uncontrolled limit heap, which represents the maximum memory available to a single virtual machine or a single process. An

) format, which is a compression format designed for Dalvik and is suitable for systems with limited memory and processor speed. Dalvik is optimized to allow instances of multiple virtual machines to run concurrently in limited memory, and each Dalvik application executes as a standalone Linux process. A standalone process can prevent all programs from shutting down when the virtual machine crashes.The DVM VM Dalvik virtual machine, which is the VM us

Android5.0, art virtual machines must be compatible with the features of Dalvik virtual machines, but art has a good feature AOT (ahead of time), This feature is that when we install the APK, Dex is processed directly into the machine code that can be used directly for the art virtual machine. Art virtual machines convert. dex files to directly run. Oat files, the art virtual machine natively supports multi-dex, so there is no one-pack process, so the art virtual opportunity is a big boost to t

discussion. I am not only responsible for the ORM responsibility but also for the DVM (Domain View Mapping) responsibilities. That is, I expect my objects to be associated with other objects, and I want me to display the correct Chinese name on the UI instead of the field name. First, the ORM, the correlation (inheritance is not expected to be automatically generated), I can be based on the primary foreign key relationship of the database table gener

Column compression, a new compression mode, consumes more CPU power to achieve a smaller storage consumption, column compression for the application is transparent, the Data warehouse system is worth trying this new feature. 5. Data Pump Legacy Mode The original exp in the 11GR2 is no longer supported, and IMP is still allowed to use it. So 11GR2 provides a compatibility mode that allows the previous exp and IMP scripts to be used in the data pump to provide a smoother upgrade experience for
