android中的上下文内存泄漏

Question

我在开发者博客上读过有关上下文内存泄漏的内容。

但我不确定我是否理解它。

由于上下文引用，方法getAppVersion是否会导致内存泄漏？

public class A
{

public static int getAppVersion(Context context) {
        try {
            PackageInfo packageInfo = context.getPackageManager()
                    .getPackageInfo(context.getPackageName(), 0);
            return packageInfo.versionCode;
        } catch (NameNotFoundException e) {
            // should never happen
            throw new RuntimeException("Could not get package name: " + e);
        }
    }

}

public class B extends Activity
{

@Override
    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
        setContentView(R.layout.b);

       int version = A.getAppVersion(this);

}

}
