原因：app跳转跳转外链（如百度）时由于手机没有安装浏览器发生崩溃

解决方法：1.最简单的方法加个try catch 抛异常处理

try{
    Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("http:"));
    startActivity(intent);
}catch (ActivityNotFoundException a){
    a.getMessage();
}
2.或者判断手机中浏览器的个数

private boolean hasBrowser(Context context){
    PackageManager pm = context.getPackageManager();
    Intent intent = new Intent(Intent.ACTION_VIEW);
    intent.addCategory(Intent.CATEGORY_BROWSABLE);
    intent.setData(Uri.parse("http://"));

    List list = pm.queryIntentActivities(intent, PackageManager.GET_INTENT_FILTERS);
    final int size = (list == null) ? 0 : list.size();
    return size > 0;
}
