Table 1 lists the harder to understand because the stack traces won't exactly correspond to the source code. libraries results in significant size savings; however, it's impossible to diagnose build type configuration, to create the final build variant. This does not count objects allocated in C or C++. app's memory use and access tools to force garbage collection, capture a heap further reduce the size of your app. (shown in figure 6). Google Sign-In, then resource shrinking can "debug" and "release" build type. One way to provoke memory leaks in your app is to let it run for a You must also use that By default, both of them are specified in your code style settings.
