我在开发的时候使用webview，在android4.4环境下，第一次进入webview正常，但是到第二次或第三次的时候就会崩溃了。
报错为：
A resource was acquired at attached stack trace but never released. See java.io.Closeable for information on avoiding resource leaks.。
java.lang.Throwable: Explicit termination method 'close' not called
初步定为是内存泄露，但是不知道应该怎么回收，在哪儿回收？请大神赐教。
代码如下：

扫了一遍代码，有可能是因为这个泄露了。
InputStream in = new FileInputStream(pathName);
应该在 finally 里面关闭。
try {
InputStream in = new FileInputStream(pathName);
//...
} finally {
if (in != null) {
in.close();
}
}
