我制作了一个简单的 Android 应用程序，它试图通过单击按钮打开一个 URL（任何带有输入的 URL 都可以）。我使用的代码是这样的：
btnTest = (Button)findViewById(R.id.btnTest);
btnTest.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
HelloActivity.this.startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://www.google.com")));
}
});
问题是在运行平台 4.0.3 的 Android 模拟器中，每次我尝试使用软键盘将文本输入网络时，模拟器都会崩溃。在运行 Platform 2.3.3 的模拟器中不会出现此问题。我试过很多网站，它的行为都是一样的。
顺便说一句，这是 logcat ：
