能否telephony.Phone对象通过SDK进行实例化？ [英] Can a telephony.Phone object be instantiated through the sdk?

问题描述

我想获得一个电话对象，这样我可以打电话，从我的应用研讨会两个数字。

I am trying to get a phone object so that I can call and conference two numbers from within my application.

我已经使用静态PhoneFactory.makeDefaultPhones（（上下文）本）尝试，但还没有任何运气。

I have tried using the static PhoneFactory.makeDefaultPhones((Context)this) but have not had any luck.

String phoneFactoryName = "com.android.internal.telephony.PhoneFactory";
String phoneName = "com.android.internal.telephony.Phone";
Class phoneFactoryClass = Class.forName(phoneFactoryName);
Class phoneClass = Class.forName(phoneName);
Method getDefaultPhone = phoneFactoryClass.getMethod("getDefaultPhone");
Object phoneObject = getDefaultPhone.invoke(null);

错误 - 通过了java.lang.RuntimeException引起：PhoneFactory.getDefaultPhone必须从弯针线被称为

Error - Caused by java.lang.RuntimeException: PhoneFactory.getDefaultPhone must be called from Looper thread

推荐答案

是的，它可以被实例化。但你必须克服几个障碍：

Yes it can be instantiated. But you have to overcome a couple of hurdles:

• 在你的Andr​​oidManifest.xml中设置

• In your AndroidManifest.xml set

安卓sharedUserId =android.uid.phone

android:sharedUserId="android.uid.phone"

清单-标签内。该时间是从保护意图是由你可以调用（如android.intent.action.SIM_STATE_CHANGED）的方式发送被抛出需要prevent一个SecurityException。

within the manifest-Tag. This is required to prevent a SecurityException from being thrown when protected Intents are sent by the methods you may invoke (like android.intent.action.SIM_STATE_CHANGED).

设置

安卓程序=com.android.phone

android:process="com.android.phone"

在您的应用程序标签。这是为了让getDefaultPhone / makeDefaultPhone的调用。

in your application-Tag. This is required to allow the invocation of getDefaultPhone / makeDefaultPhone.

要做到这一切，您的应用程序必须与系统签名密钥进行签名。

To do all this your app must be signed with the system signature key.
