无活动处理意向与action.DIAL [英] No Activity found to handle Intent with action.DIAL

问题描述

我似乎缺乏有关处理这种意图的知识，但无法找到一会儿回答。

I seems to be lacking knowledge about handling such intents, however couldnt find answer for a while.

我有一个片段的活动。片段中调用联系人的目的，执行该code：

I have an activity with one fragment. The fragment executes this code in purpose of calling a contact:

private void onCall() {
    Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse(contact.getBusinessPhone()));
    startActivity(intent);
}

还包括允许

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission> 

输出为无活动来处理意图键，应用程序崩溃。

The output is No Activity found to handle Intent and the app crashes.

下面是体现执行保存碎片的活动：

Here is manifest implementation of the activity that holds fragment:

<activity android:name="activities.ContactActivity">            
    <intent-filter>
        <action android:name="android.intent.action.DIAL" />
        <category android:name="android.intent.category.DEFAULT" />
    </intent-filter>
</activity>

我是什么做错了吗？我需要在清单中声明为一些特殊的活动？

What am I doing wrong? Do I need some special activity declared in manifest for that?

推荐答案

您并不需要声明拨打意图过滤器清单中，不需要任何权限ACTION_DIAL。寻找我的执行

You don't need to declare dial intent-filter in manifest and don't need any permissions to ACTION_DIAL. Look for my implementation

private void startDialActivity(String phone){
    Intent intent = new Intent(Intent.ACTION_DIAL);
    intent.setData(Uri.parse("tel:"+phone));
    startActivity(intent);
}

也是很好的检查是电话支持设备

also is good to check is telephony supported on device

private boolean isTelephonyEnabled(){
    TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
    return tm != null && tm.getSimState()==TelephonyManager.SIM_STATE_READY
}
