memory, there is no 8G so much good. Because of their own machine is 8G, and run on the virtual machine, only allocated to 4G of space, so the process of build, memory problems stuck themselves for a long time, and the official said, it is best to have 16g ram above, almost give up. Finally think of a way to increase swap memory. As for how to increase swap memory, refer to here. their direct swap inc

architectures have pros and cons, and generally, stack-based machines require more instructions, and register-based machine instructions are larger. DX is a set of tools that convert Java. class to. dex format. A DEX file typically has more than one. Class. Since Dex has to be optimized, it will increase the file size by 1-4 times, ending with Odex.Dalvik virtual machines rely on the Linux kernel to provide basic functionality, such as threading and

Analysis of the source before the introduction of the ARRAYMAP storage structure, ARRAYMAP data storage is different from HashMap and Sparsearray. Java provides hashmap, but HashMap is too much space for mobile phones, so Android offers Sparsearray and Arraymap. Both are based on two-point lookup, so when the data volume is large, the worst efficiency is much slower than HashMap. Therefore, the proposed qu

like to make a personal summary. From my personal development experience, the AsyncTask class has indeed been well encapsulated, the interaction between the asynchronous thread and the UI thread has been well processed, so developers can happily program the classes provided by Google. If you consider the number of concurrent tasks, you can also use interfaces provided after 3.0 to increase the number of concurrent operations, but we still need to pro

most effective way to compile. Maybe the steps in these articles are inconsistent with those mentioned above. 1. Select ubuntu12.04I used x64 for the first time and found many errors when configuring the environment. Later I used a 32-bit system and installed these necessary software without any errors, so here, if cyanogenmod ICS source code is compiled using the 12.04 system, I recommend using a 32-bit system with my personal experience. 2.

(); } } Modify this. getResources () to this. getApplication (). getResources (). After modification, some Resources objects have Application object references. If the Activity is re-created, the Activity created for the first time can be recycled. 3) Close resources in time Cursor Is a class used to manage data sets after data is queried by Android. Normally, if we do not close it, the system will close it when it is recycled, but this
