我連接一個ıp凸輪（jpeg），並顯示此圖像，並ı不斷重複，過了一段時間我的應用程序錯誤這個。我測試了其他手機並展示了這款手機。我無法解決這個問題...（一段時間後，我的應用程序錯誤...）

10-28 15:12:51.525: ERROR/AndroidRuntime(675): Uncaught handler: thread Thread-11 exiting due to uncaught exception

我的代碼：

public void parse(InputStream is){ 
    try { 
    if (!type.isMjpegStream()) { 
    CameraManagerScreen.ActiveCam.setConnected(true); 
    setImage(is); 
    is.close(); 
    System.gc(); 
    if(!mjpeghttp.isCanceled()) 
     go(); 
    } 
    } catch (Exception e) { 
    } 
}

，我的連接是：

protected void connect() { 
InputStream is = null; 

try { 



HttpParams httpParameters = new BasicHttpParams(); 
// Set the timeout in milliseconds until a connection is 
// established. 
int timeoutConnection = 20000; 
HttpConnectionParams.setConnectionTimeout(httpParameters, 
    timeoutConnection); 
// Set the default socket timeout (SO_TIMEOUT) 
// in milliseconds which is the timeout for waiting for data. 
int timeoutSocket = 20000; 
HttpConnectionParams.setSoTimeout(httpParameters, timeoutSocket); 

client = new DefaultHttpClient(httpParameters); 

method = new HttpGet(getUrl()); 
System.out.println("Baglanıyor: " + method.getURI().toString()); 
method.addHeader("Authorization", getBase64Encode()); 

res = client.execute(method); 
System.out.println("RESPONSE: " 
    + res.getStatusLine().getStatusCode()); 

is = res.getEntity().getContent(); 

if (!cancel) { 
    onReturn(res.getStatusLine().getStatusCode(), is); 

} 

} catch (Exception e) { 
System.out.println(e.getMessage()); 

try { 

    cancel = true; 

    Thread.sleep(60); 

} catch (Exception ie) { 
} 
onError(new Exception("0")); 
} 
}

錯誤......

public void parse(InputStream is){ 
    if(!mjpeghttp.isCanceled()) 
     go();

究竟母鹿s go()呢？它要求connect()，什麼再次呼籲

if (!cancel) { 
    onReturn(res.getStatusLine().getStatusCode(), is); 
}

而且onReturn()電話parse()。 parse()來電go()來電connect()來電onReturn()來電parse()來電...它從不（？）結束。爲什麼解析必須連接？每個函數調用都需要一點內存。大量的調用後，沒有更多的內存，你會得到一個堆棧溢出異常。

你需要在某個地方打破圓圈。你可以刪除此：

if(!mjpeghttp.isCanceled()) 
    go();

我不認爲它甚至睡一次

try { 

    cancel = true; 
    System.out.println("Sleep sleep!"); 
    Thread.sleep(60); 

} catch (Exception ie) {

是否打印呢？

怎麼樣？

imageSet=false; 
while(!imageSet) 
{ 
    if (connect()) 
    if(parse()) 
     imageSet=true; 
}

解析不得不重新連接，因爲連接帶來的JPEG圖像，分析圖像設置。另一方面，我的處理程序將此圖像設置爲屏幕。總是一張圖片應該來... – atasoyh 2010-10-28 12:31:26

它看起來好像你一直保持嵌套調用，直到堆棧溢出（這個網站非常合適的問題= P）。

我猜你希望實際上有連接方法返回一個值，而不是調用onReturn方法。這會阻止你的遞歸嵌套，並應該擺脫這個特定的問題。

謝謝。但爲什麼你認爲「這個網站非常合適的問題= P」）。「 – atasoyh 2010-10-28 12:34:40

因爲這個站點叫做stackoverflow，所以你得到的錯誤是'stackoverflow'... – 2010-10-28 13:00:27

我解決這樣的..再次感謝您... :)當然我刪除
if(!mjpeghttp.isCanceled()) go();

// start connection to ip-camera 
public void go() { 

    if (mjpeghttp == null) { 
     mjpeghttp = new MjpegHttp(); 
     mjpeghttp.start(); 

    } 
    if (type.isMjpegStream()) { 
     mjpeghttp.go(this); 
    } else { 
     while (mjpeghttp.isCanceled()==false) 
      mjpeghttp.go(this); 
    } 

}
