Getting the Ram amount from a given package

Question

I was wondering how I could get the amount of RAM usage of a given application or a package name that is installed in the android device. I so far went on with a package manager and feeding it with the package name I want. However, there is no method that I could use to get it out. I don't know what to do after this. Please some one help me on getting the RAM amount that a particular application is using currently.

You can use adb tools to get memory information that app consume

adb shell dumpsys meminfo

can take this output to textfile by adb shell dumpsys meminfo > meminfo.txt

M sorry, bt the thing I want is not my own application memory usage. what I want is to get the memory usage of another application within my application. to be clear, m building an application to get the usage statistics all the installed applications. I came so far nd M stuck at the place where when I select a certain application and I want to show what the current memory usage of the selected app! :) – Imesh Chandrasiri Jul 08 '12 at 16:17
you can issue adb commands from your android application, try.. Runtime runtime = Runtime.getRuntime(); try { runtime.exec("adb shell dumpsys meminfo"); } catch (IOException e) { e.printStackTrace(); }.. then you can filter result by your required app package info. http://developer.android.com/reference/java/lang/Runtime.html#exec%28java.lang.String[],%20java.lang.String[]%29 – UdayaLakmal Jul 08 '12 at 16:26

this function help you :

public static void logHeap(Class<?> clazz) {
        Double allocated = new Double(Debug.getNativeHeapAllocatedSize())/new Double((1048576));        
        Double available = new Double(Debug.getNativeHeapSize()/1048576.0);
        Double free = new Double(Debug.getNativeHeapFreeSize()/1048576.0);
        DecimalFormat df = new DecimalFormat();
        df.setMaximumFractionDigits(2);
        df.setMinimumFractionDigits(2);

        Log.d("memory-usage", "===================================================================================================");
        Log.d("memory-usage", "debug.heap native: allocated " + df.format(allocated) + "MB of " + df.format(available) + "MB (" + df.format(free) + "MB free) in [" + clazz.getName().replaceAll("com.myapp.android.","") + "]");
        Log.d("memory-usage", "debug.memory: allocated: " + df.format(new Double(Runtime.getRuntime().totalMemory()/1048576)) + "MB of " + df.format(new Double(Runtime.getRuntime().maxMemory()/1048576))+ "MB (" + df.format(new Double(Runtime.getRuntime().freeMemory()/1048576)) +"MB free)");

        System.gc();
        System.gc();
    }
