java - 从 Android 应用程序通过电子邮件发送崩溃报告

Question

嘿伙计们，我需要帮助配置一些源代码，以便基本上在发生错误时通过电子邮件向我发送崩溃报告。这是我正在玩的一些代码，我只需要对 Java 有更多经验的人来忽略它并帮助我清理它。

谢谢，

public final class EmailUtils {

private EmailUtils()
 {
 }

 {
    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());
 }

My Main goal is to pull system data and intent out. Do you recommend using the ACRA way or using my string method?

绝对是 ACRA。同样，它已经存在，受到支持，提供多种获取数据的方式(包括不公开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:

• Never never never never never never never never 对资源 ID 十六进制值进行硬编码，例如:String s = context.getResources().getString(0x7f040000);。这些值会随着每次构建而改变，尤其是当您添加/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 对象并附加到它。不要创建 30 个左右，每个使用一次然后丢弃。
