Monitor the memory ocuppied by my app in Android

Question

im attempting to optimize the amount of memory my app consumes. When my app loads (holding home key and then selecting task manager) i can see the app is taking 17MB but that value doesn't refresh. How can I track that value in real time? DDMS have a option for that? Please be specific I have searched a lot and nothing found. thanks in advance

Another more code-oriented debug method for memory tracking appears in https://stackoverflow.com/a/6471227/978329 with a link to a blog with more info.

To make it short, you can carefully put the following code (or an improved version of it) into some kind of on click event and get the real-time info into a log or a toast message:

View v = (View) findViewById(R.id.SomeLayout);

    v.setOnClickListener(new OnClickListener() {
        public void onClick(View view) {

            Debug.MemoryInfo memoryInfo = new Debug.MemoryInfo();
            Debug.getMemoryInfo(memoryInfo);

            String memMessage = String.format("App Memory: Pss=%.2f MB, Private=%.2f MB, Shared=%.2f MB",
                    memoryInfo.getTotalPss() / 1024.0,
                    memoryInfo.getTotalPrivateDirty() / 1024.0,
                    memoryInfo.getTotalSharedDirty() / 1024.0);

            Toast.makeText(ThisActivity.this,
                    memMessage,
                    Toast.LENGTH_LONG).show();
            Log.i("log_tag", memMessage);
        }
        });
