我有一个应用程序与webview。在webview中有一个表单:
<select>
<option value='1'>Something</option>
</select>
当选择字段被点击android将调用android.widget. checkedtextview
我发现在一些设备上这会导致崩溃(见下面的日志)
所以我的问题是，我怎样才能避免这个崩溃?也许可以扩展webview并在android调用CheckedTextView之前添加try{}。

我发现如果我在build gradle
中替换以下行compile 'com.android.support:appcompat-v7:23.2.0'
compile 'com.android.support:appcompat-v7:23.1.1'
解决了问题。
我不完全确定为什么，但显然有一些不同的appcompat版本不能很好地与早期的android版本。
