问题描述
我试图访问 CallManager的
类对象从 com.android.internal.telephony
包。
I am trying to access CallManager
class object from com.android.internal.telephony
package.
下面是我的code:
ClassLoader classLoader = TestActivity.class.getClassLoader();
final ClassLoader classLoader = this.getClass().getClassLoader();
try {
final Class<?> classCallManager =
classLoader.loadClass("com.android.internal.telephony.CallManager");
Log.i("TestActivity", classCallManager);
} catch (final ClassNotFoundException e) {
Log.e("TestActivity", e);
}
不幸的是,这是抛出一个 ClassNotFoundException的
。同样的方法可以让我访问 PhoneFactory
,但显然我不能访问 CallManager的
。
Unfortunately, this is throwing a ClassNotFoundException
. The same approach allows me to access PhoneFactory
, but apparently I'm not allowed to access CallManager
.
如果我能达到的类,那么我想使用类进行如下操作:
If I could reach the class, then I'd want to proceed using the class as follows:
Method method_getInstance;
method_getInstance = classCallManager.getDeclaredMethod("getInstance");
method_getInstance.setAccessible(true);
Object callManagerInstance = method_getInstance.invoke(null);
任何人都可以帮助我在这?
Can anyone help me on this?
在前进,
谢谢戒ç

推荐答案
我能成功加载CallManager和它的方法。然而,当我调用的getState(),getActiveFgCallState(),它总是返回空闲即使当应用程序接收到来自TelephonyManager,即TelephonyManager.CALL_STATE_IDLE,TelephonyManager.CALL_STATE_OFFHOOK,TelephonyManager.CALL_STATE_RINGING不同的呼叫状态。
I could successfully load CallManager and its methods. However, when I invoke getState(), getActiveFgCallState(), it always return IDLE even when the app receives different call states from TelephonyManager, i.e. TelephonyManager.CALL_STATE_IDLE, TelephonyManager.CALL_STATE_OFFHOOK, TelephonyManager.CALL_STATE_RINGING.
我用下面的code加载类及其方法:
I used the following code to load the class and its methods:
final Class<?> classCallManager = classLoader.loadClass("com.android.internal.telephony.CallManager");
Log.i(TAG, "Class loaded " + classCallManager.toString());
Method methodGetInstance = classCallManager.getDeclaredMethod("getInstance");
Log.i(TAG, "Method loaded " + methodGetInstance.getName());
Object objectCallManager = methodGetInstance.invoke(null);
Log.i(TAG, "Object loaded " + objectCallManager.getClass().getName());
Method methodGetState = classCallManager.getDeclaredMethod("getState");
Log.i(TAG, "Method loaded " + methodGetState.getName());
Log.i(TAG, "Phone state = " + methodGetState.invoke(objectCallManager));
顺便说一句,我所要做的是检测的时候,手机响起。我在源$ C $ c表示ALERTING是内部事件,我应该听看到的。因此,我试图用CallManager的获得Call.State,而不是Phone.State。我还试图用registerFor preciseCallStateChanges CallManager的类的(),但没有上前工作至今。
Btw, what I am trying to do is detecting when the phone starts ringing. I saw in the source code that ALERTING is the internal event that I should listen to. Therefore, I tried to use CallManager to get Call.State, rather than Phone.State. I also tried to use registerForPreciseCallStateChanges() of CallManager class but none of approached worked so far.
