Corrade::Utility::AndroidLogStreamBuffer class

#include <Corrade/Utility/AndroidLogStreamBuffer.h>

Stream buffer that sends the data to Android log.

Usable in conjunction with std::ostream to redirect the output to Android log buffer, which can later be accessed through the adb logcat utility. The data are sent on each std::ostream::flush() call (which is called implicitly on each std::endl) and then the internal buffer is cleared. Example usage:

Utility::AndroidLogStreamBuffer buffer{
    Utility::AndroidLogStreamBuffer::LogPriority::Info, "my-application"};

std::ostream out{&buffer};

out << "Hello World!" << std::endl;

From the console you can then use adb logcat and filter out everything except the "my-application" tag. The output might then look like this:

$ adb logcat *:S my-application
...
03-16 17:02:21.203 16442 16442 I my-application: Hello World!

The output stream can be also used with Debug classes — simply pass the std::ostream instance to the constructor.
