Android 如何收集已釋出程式的崩潰資訊

//當執行緒因未捕獲的異常而突然終止時，呼叫處理程式的介面
static interface UncaughtExceptionHandler

//設定當執行緒由於未捕獲到異常而突然終止，並且沒有為該執行緒定義其他處理程式時所呼叫的預設處理程式。
static void setDefaultUncaughtExceptionHandler(Thread.UncaughtExceptionHandler eh)

class MythouCrashHandler implements UncaughtExceptionHandler

        this.defaultUEH = Thread.getDefaultUncaughtExceptionHandler();
    }
　　//這個介面必須重寫，用來處理我們的異常資訊
    @Override
    public void uncaughtException(Thread thread, Throwable ex)
    {
        final Writer result = new StringWriter();
        final PrintWriter printWriter = new PrintWriter(result);
　　　　 //獲取跟蹤的棧資訊，除了系統棧資訊，還把手機型號、系統版本、編譯版本的唯一標示
        StackTraceElement[] trace = ex.getStackTrace();
        StackTraceElement[] trace2 = new StackTraceElement[trace.length+3];
        System.arraycopy(trace, 0, trace2, 0, trace.length);
