    text
    copied!<p>I use a WebView to display some internet content on one of our app's Activities.<br> The problem is that when the user switches out of this activity, WebView's threads keep running!<br> The problematic threads are:</p> <pre><code>Thread [&lt;17&gt; WebViewCoreThread] (Running) Thread [&lt;25&gt; CookieSyncManager] (Running) Thread [&lt;19&gt; http0] (Running) Thread [&lt;29&gt; http1] (Running) Thread [&lt;31&gt; http2] (Running) Thread [&lt;33&gt; http3] (Running) </code></pre> <p>Pausing each one of these threads, and checking what it is busy doing:</p> <pre><code>Thread [&lt;17&gt; WebViewCoreThread] (Suspended) Object.wait(long, int) line: not available [native method] MessageQueue(Object).wait() line: 288 MessageQueue.next() line: 148 Looper.loop() line: 110 WebViewCore$WebCoreThread.run() line: 471 Thread.run() line: 1060 Thread [&lt;25&gt; CookieSyncManager] (Suspended) Object.wait(long, int) line: not available [native method] MessageQueue(Object).wait(long) line: 326 MessageQueue.next() line: 144 Looper.loop() line: 110 CookieSyncManager(WebSyncManager).run() line: 90 Thread.run() line: 1060 Thread [&lt;19&gt; http0] (Suspended) Object.wait(long, int) line: not available [native method] RequestQueue(Object).wait() line: 288 ConnectionThread.run() line: 93 </code></pre> <p>I wonder how can I tell the <code>Looper</code> in each of those threads to quit.</p> <p>I tried calling <code>webView.destroy()</code> in the activity's <code>onPause()</code> method, but it had no influence.<br> When I disable the call for opening a web page in the webView ( <code>webView.loadUrl(...)</code> ), those threads naturally are not started, and therefore don't stay on after leaving the activity.</p> <p>Any ideas as to how I can make <code>WebView</code>'s threads stop after leaving their activity?</p>
