android：iTelephony

Question

我正在开发Android 2.2 / 2.3，需要使用iTelephony提供的一些api。

我尝试过几种方法来访问一些隐藏的API，但它不起作用。

如果有人成功尝试或欢迎任何建议，请告诉我。

  

遇到异常：WARN / System.err（827）：java.lang.NoSuchMethodException：getActiveCallsCount

EG。 getActiveCallsCount(); getHoldCallsCount(); getCallTime() etc...

以下是我的示例代码：

private void getActiveCallCounts() {
        try {
            Class serviceManagerClass = Class.forName("android.os.ServiceManager");
            Method getServiceMethod = serviceManagerClass.getMethod("getService", String.class);
            Object phoneService = getServiceMethod.invoke(null, "phone");

            Class ITelephonyClass = Class.forName("com.android.internal.telephony.ITelephony");
            Class ITelephonyStubClass = null;
            for (Class clazz : ITelephonyClass.getDeclaredClasses()) {
                if (clazz.getSimpleName().equals("Stub")) {
                    ITelephonyStubClass = clazz;
                    break;
                }
            }
            if (ITelephonyStubClass != null) {
                Class IBinderClass = Class.forName("android.os.IBinder");
                Method asInterfaceMethod = ITelephonyStubClass.getDeclaredMethod("asInterface", IBinderClass);
                Object iTelephony = asInterfaceMethod.invoke(null, phoneService);
                if (iTelephony != null) {
                    Method getActiveCallsCountMethod = iTelephony.getClass().getMethod("getActiveCallsCount");                      
                    Integer output= getActiveCallsCountMethod.invoke(iTelephony);        
                    System.out.println("got call count.. " + output.intValue()); 
                } else {
                    Log.w("TTT", "Telephony service is null, can't call "
                            + "getActiveCallsCount");
                }
            } else {
                Log.d("TTT", "Unable to locate ITelephony.Stub class!");
            }
        } catch (Exception ex) {
            ex.printStackTrace();
            Log.e("TTT", "Failed to get active call count due to Exception!" + ex.getMessage());
        } 

    }

Answer 1

您可以构建Android源代码，将输出out/target/common/obj/JAVA_LIBRARIES/framework_intermediates/classes.jar添加到项目的类路径中。然后你可以直接使用隐藏方法和内部类。

Answer 2

这些方法（getActiveCallsCount（）; getHoldCallsCount（）; getCallTime（））不包含在类com.android.internal.telephony.ITelephony

中
