通過電子郵件從Android App發送崩潰報告

Question

大家好，我需要配置一些源代碼，基本上在發生錯誤時會通過電子郵件向我發送崩潰報告。 這是一些我正在玩的代碼，我只需要一個對Java有更多經驗的人就可以忽略並幫助我清理它。

謝謝，

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());
 }

我的主要目標是提取系統數據和意圖。 您是否建議使用ACRA方式或我的字符串方法？

絕對是ACRA。 同樣，它已經存在，受到支持，提供了多種獲取數據的方法（包括不公開您的電子郵件地址的方法），與BugSense等第三方服務集成。

更具體地講我的兩個代碼注釋：

• 永遠不會永遠不會永遠不會永遠不會永遠不會硬編碼資源ID十六進制值，例如： String s = context.getResources().getString(0x7f040000); 。 這些值可以隨每次構建而變化，尤其是在添加/刪除資源時。 始終使用資源ID符號（例如R.string.foo ）。

• 在getEmailText() ，請創建一個 StringBuilder對象並將其追加。 不要創建30個左右的對象，不要使用一次並丟棄它。
