Question

嘿伙计我需要帮助配置一些源代码，基本上当发生错误时通过电子邮件向我发送崩溃报告。这里有一些我正在玩的代码我只需要有一点java经验的人忽略它并帮我清理它。

谢谢，

public final class EmailUtils {

private EmailUtils()
 {
 }

private static int bytesToMb(long l)
 {
    return (int)((double)l / 1024D / 1024D);
 }

private static int getAvailableInternalMemorySize()
 {
    StatFs statfs = new StatFs(Environment.getDataDirectory().getPath());
    return bytesToMb((long)statfs.getBlockSize() * (long)statfs.getAvailableBlocks());
 }

private static String getEmailText(Context context)
 {
    String s = "";
    String s11;

我的主要目标是提取系统数据和意图。您是否建议使用ACRA方式或使用我的字符串方法？

绝对是ACRA。同样，它已经存在，受支持，提供多种方式向您提供数据（包括不泄露您的电子邮件地址的方式），与BugSense等第三方服务集成。

更具体地说明我的两个代码注释：

绝不会永远不会永远不会永远不会硬编码资源ID十六进制值，例如：String s = context.getResources().getString(0x7f040000);。这些值可能随每次构建而变化，尤其是在添加/删除资源时。始终使用资源ID符号（例如，R.string.foo）。
在getEmailText()中，请创建一个 StringBuilder对象并附加到其中。不要创建30个左右，每次使用一次并丢弃它们。
