过滤

要想激发电话拨打的activity 就必须符合它所定义的intent
在platforms\android-8\sources\Phone\AndroidManifest.xml的126行

<activity android:name="OutgoingCallBroadcaster"                android:permission="android.permission.CALL_PHONE"                android:theme="@android:style/Theme.NoDisplay"                android:configChanges="orientation|keyboardHidden">            <!-- CALL action intent filters, for the various ways                 of initiating an outgoing call. -->            <intent-filter>                <action android:name="android.intent.action.CALL" />                <category android:name="android.intent.category.DEFAULT" />                <data android:scheme="tel" />            </intent-filter>            。。。。            。。。。</activity>

所以：

Intent intent = new Intent();intent.setAction("android.intent.action.CALL");intent.setData(Uri.parse("tel:"+number));MainActivity.this.startActivity(intent);
