我已经为Titanium创建了一个模块，用于将数据从我的应用程序发送到我的Android Wear应用程序，该应用程序运行良好。但是当我卸载Android应用程序崩溃时。我已经检查过Logcat，但我不知道问题到底是什么。如果我在调用module.sendData（）之后立即卸载应用程序（参见示例）
，Android似乎只会崩溃示例：
index.js（app）
function onOpen() {
var module = require('teunozz.test.module')
module.addEventListener('connected', function f() {
console.log('send data');
module.sendData();
});
module.start();
}
$.index.open();
index.xml（app）
<Alloy>
<Window id="index" onOpen="onOpen">
</Window>
</Alloy>

更新Logcat输出
这是我能找到的第一个错误。
