Подскажите пожалуйста, как вывести количества ОЗУ устройства на котором установлено приложение!
И есть ли возможность вывести всю память устройства?

ОЗУ

ActivityManager actManager = (ActivityManager) context.getSystemService(Context.ACTIVITY_SERVICE);
ActivityManager.MemoryInfo memInfo = new ActivityManager.MemoryInfo();
actManager.getMemoryInfo(memInfo);
long totalMemory = memInfo.totalMem;

Внутренняя

private static final long KILOBYTE = 1024;

StatFs internalStatFs = new StatFs( Environment.getRootDirectory().getAbsolutePath() );
long internalTotal;
long internalFree;

StatFs externalStatFs = new StatFs( Environment.getExternalStorageDirectory().getAbsolutePath() );
long externalTotal;
long externalFree;

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2) {
    internalTotal = ( internalStatFs.getBlockCountLong() * internalStatFs.getBlockSizeLong() ) / ( KILOBYTE * KILOBYTE );
    internalFree = ( internalStatFs.getAvailableBlocksLong() * internalStatFs.getBlockSizeLong() ) / ( KILOBYTE * KILOBYTE );
    externalTotal = ( externalStatFs.getBlockCountLong() * externalStatFs.getBlockSizeLong() ) / ( KILOBYTE * KILOBYTE );
    externalFree = ( externalStatFs.getAvailableBlocksLong() * externalStatFs.getBlockSizeLong() ) / ( KILOBYTE * KILOBYTE );
}
else {
    internalTotal = ( (long) internalStatFs.getBlockCount() * (long) internalStatFs.getBlockSize() ) / ( KILOBYTE * KILOBYTE );
    internalFree = ( (long) internalStatFs.getAvailableBlocks() * (long) internalStatFs.getBlockSize() ) / ( KILOBYTE * KILOBYTE );
    externalTotal = ( (long) externalStatFs.getBlockCount() * (long) externalStatFs.getBlockSize() ) / ( KILOBYTE * KILOBYTE );
    externalFree = ( (long) externalStatFs.getAvailableBlocks() * (long) externalStatFs.getBlockSize() ) / ( KILOBYTE * KILOBYTE );
}

long total = internalTotal + externalTotal;
