[英]How to import com.android.internal.telephony.ITelephony to the Android application
I want to hang up incoming call I detect it and then I want to hang it up.我想挂断来电 我检测到它然后我想挂断它。
The problem is that this: com.android.internal.telephony.ITelephony
is not resolved.问题是:
com.android.internal.telephony.ITelephony
没有解决。
I tried to adding package com.android.internal.telephony
to my application and create interface:我尝试将 package
com.android.internal.telephony
添加到我的应用程序并创建界面:
package com.android.internal.telephony;
public interface ITelephony {
boolean endCall();
void answerRingingCall();
void silenceRinger();
}
but the call is not ended.但通话并未结束。
Here I detect call, display toast(it is displayed) then try to hang up but as I said first there was no com.android.internal.telephony.ITelephony
before I created that package:在这里,我检测到呼叫,显示 toast(已显示)然后尝试挂断,但正如我首先所说,在我创建
com.android.internal.telephony.ITelephony
之前没有 com.android.internal.telephony.ITelephony:
private class CallStateListener extends PhoneStateListener {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
switch (state) {
case TelephonyManager.CALL_STATE_RINGING:
// called when someone is ringing to this phone
Toast.makeText(ctx, "Incoming: " + incomingNumber, Toast.LENGTH_LONG).show();
try{
TelephonyManager tm = (TelephonyManager) ctx.getSystemService(Context.TELEPHONY_SERVICE);
Class c = Class.forName(tm.getClass().getName());
Method m = c.getDeclaredMethod("getITelephony");
com.android.internal.telephony.ITelephony telephonyService = (com.android.internal.telephony.ITelephony) m.invoke(tm);
telephonyService = (com.android.internal.telephony.ITelephony) m.invoke(tm);
telephonyService.silenceRinger();
telephonyService.endCall();
}catch (Exception e) {
e.printStackTrace();
}
break;
}
}
}
My Manifest and permissions:我的清单和权限:
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.example.a"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="17"
android:targetSdkVersion="17" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
<uses-permission android:name="android.permission.PROCESS_OUTGOING_CALLS" />
<uses-permission android:name="android.permission.CALL_PHONE" />
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity

</activity>

</application>
</manifest>
The ITelephony
interface is internal, so you cannot get a standard reference to it. ITelephony
接口是内部的,因此您无法获得对它的标准引用。 You could use reflection all the way, ie你可以一直使用反射,即
TelephonyManager tm = (TelephonyManager) getSystemService(TELEPHONY_SERVICE);
Method m1 = tm.getClass().getDeclaredMethod("getITelephony");
m1.setAccessible(true);
Object iTelephony = m1.invoke(tm);
Method m2 = iTelephony.getClass().getDeclaredMethod("silenceRinger");
Method m3 = iTelephony.getClass().getDeclaredMethod("endCall");
m2.invoke(iTelephony);
m3.invoke(iTelephony);
But either way those methods need the MODIFY_PHONE_STATE
permission, which can only be granted to system apps.但无论哪种方式,这些方法都需要
MODIFY_PHONE_STATE
权限,该权限只能授予系统应用程序。 So I'm afraid it won't work anyway.所以恐怕无论如何都行不通。
For kotlin:对于科特林:
val tm = context.getSystemService(Context.TELEPHONY_SERVICE) as TelephonyManager
val m1 = tm::class.java.getDeclaredMethod("getITelephony")
m1.setAccessible(true)
val telephonyService = m1.invoke(tm)
val m2 = telephonyService::class.java.getDeclaredMethod("silenceRinger")
val m3 = telephonyService::class.java.getDeclaredMethod("endCall")
m2.invoke(telephonyService)
m3.invoke(telephonyService)
For Android API 28 and above you can use the following code对于Android API 28及以上可以使用以下代码
TelecomManager telecomManager = (TelecomManager) context.getSystemService(Context.TELECOM_SERVICE);
if (ActivityCompat.checkSelfPermission(context, Manifest.permission.ANSWER_PHONE_CALLS) != PackageManager.PERMISSION_GRANTED) {
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.P) {
telecomManager.endCall();
}
}else{
//Ask for permission here
}
Also add this permission in your app manifest file还要在您的应用程序清单文件中添加此权限
<uses-permission android:name="android.permission.ANSWER_PHONE_CALLS" />
