    int maxMemory = (int) (Runtime.getRuntime().maxMemory() / 1024);  

        Log.e("TAG", "Max memory is " + maxMemory + "KB");  

        Log.e("TAG", "Max memory is " + maxMemory /1024 + "MB");  

        Log.e("TAG", "Max memory is " + maxMemory /1024/1024 + "GB");                              

 

//执行结果如下：

/*

    TAG    Max memory is 65536KB

    TAG    Max memory is 64MB

    TAG    Max memory is 0GB

*/
