java - 尝试在 Oreo 设备上创建新的 'Session' 对象时出现 fatal error

Question

我有一个项目在 android 6.0 上运行良好，但是当我在 Android 8.0 上运行它时，它会破坏该方法:

try
{
    mSession = new Session(mContext, api_key, session_id);  // Crush Here!
}
catch (Exception e)
{
    e.printStackTrace();  // Never Gets to the catch! why ??!
}

在它的内部，在方法上:

this.init(cacertFile, context, hwdecoding, apiKey, sessionId, model, apiLevel);

在“Session.class”文件中。

我授予了设备内部存储读/写所需的权限。

可能是什么问题？

以下是我收集的一些可能有帮助的数据:

<小时/>

 * * * Crush on the "new Session(...)" method:
 =============================================

private void sessionConnect(String api_key, String session_id, String token)
{
    if (mSession == null) 
    {
        try
        {
            mSession = new Session(mContext, api_key, session_id);  // Crush Here!
        }
        catch (Exception e)
        {
            e.printStackTrace();  // Never Gets to the catch! Why ???
        }

            mSession.setSessionListener(this);
            mSession.setConnectionListener(this);
            mSession.setSignalListener(this);
            mSession.connect(token);
        }
    }

 * * * Debug params just before the crush:
 =========================================


    this = {OpenTokStreamer@5445} 
    api_key = "45276332"
    session_id = "1_MX40NTI3NjMzMn5-MTU0MTY2MzEwNjMwMH5mbVZiWGdYN0tETVNWeEZkOE9KVmRKYzd-fg"
    token = "T1==cGFydG5lcl9pZD00NTI3NjMzMiZzaWc9MGQ3ZThlYjFmYzcyZGUzMGY1NDBkM2NjNGMwZDQ2YTIzOWUwMmZiZTpzZXNzaW9uX2lkPTFfTVg0ME5USTNOak16TW41LU1UVTBNVFkyTXpFd05qTXdNSDVtYlZaaVdHZFlOMHRFVFZOV2VFWmtPRTlLVm1SS1l6ZC1mZyZjcmVhdGVfdGltZT0xNTQxNjkxMjcyJm5vbmNlPTAuNTkwMzE0MjA5NDYxMjEyMiZyb2xlPW1vZGVyYXRvciZleHBpcmVfdGltZT0xNTQxNzc3Njcy"
    mSession = null
    mContext = {Application@5449} 
     mActivityLifecycleCallbacks = {ArrayList@5453}  size = 0
     mAssistCallbacks = null
     mComponentCallbacks = {ArrayList@5454}  size = 0
     mFlipfont = 0
     mLoadedApk = {LoadedApk@5455} 
     mBase = {ContextImpl@5456} 
     shadow$_klass_ = {Class@1873} "class android.app.Application"
     shadow$_monitor_ = -2030428451

---------------------------------------------------------------------------------

 * * * If I do Step-Into, then I can see that it crush on the method:
 ====================================================================

    this.init(cacertFile, context, hwdecoding, apiKey, sessionId, model, apiLevel);


 * * * Debug params just before the crush:
 =========================================


    this = {Session@5445} 
    context = {Application@5441} 
    apiKey = "45276332"
    sessionId = "1_MX40NTI3NjMzMn5-MTU0MTY2MzEwNjMwMH5mbVZiWGdYN0tETVNWeEZkOE9KVmRKYzd-fg"
    sessionOptions = {Session$DefaultSessionOptions@5449} 
    cacertFile = "/data/user/0/com.myVideoApp/cache/.ca-cert.pem"
    hwdecoding = false
    model = 0
    apiLevel = 26


---------------------------------------------------------------------------------

 * * * Logcat a little before and after the Fatal crush:
 =======================================================
