Android memory monitoring tool ddms --> heap. Original address To monitor the memory usage of an application process using heap, follow these steps:1. After eclipse is started, switch to the ddms perspective and confirm that the devices view and heap view are all open;2. Connect your phone to your computer via USB. Make sure that the phone is in "USB debugging" mode instead of "Mass Storage ";3. After the c

No matter how careful you are, it is impossible to completely avoid bad code. At this time, some tools are required to help us check whether there is any place in the code that will cause memory leakage. The ddms in Android tools comes with a very good memory monitoring tool heap (here I use the ADT plug-in of eclipse, and take the real machine as an example, the situation in the simulator is similar ).
