问题描述
是否可以以编程方式在android中接听电话?
Is it possible to answer call in android programmatically?
我发现了一些不可能的地方,但随后安装了应用 https://play.google.com/store/apps/details?id=com.a0softus.autoanswer 工作正常.
I found some where that its not possible but then installed app https://play.google.com/store/apps/details?id=com.a0softus.autoanswerits working fine.
我已经搜索了很多东西,尝试了很多事情,而且通话拒接效果很好,但是电话接听不起作用.
I have searched a lot and tried many things, moreover call rejection is working fine but call answering not working.
我尝试了以下代码进行电话应答,如下所示:
I have tried the following code for call answering as shown below:

String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
// Get incoming number
incomingNumber = intent.getStringExtra(TelephonyManager.EXTRA_INCOMING_NUMBER);
}
}
if (!incomingNumber.equals("")) {
// Get an instance of ContentResolver

if(numbers.getCount()<=0){ // The incoming number is not found in the contacts list*/
// Turn on the mute

Intent intent = new Intent(context, MainActivity.class);
intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.putExtra("number", "Rejected incoming number:" + number);
context.startActivity(intent);
}

try {
mediaPlayer.reset();
mediaPlayer.setDataSource(afd.getFileDescriptor(), afd.getStartOffset(), afd.getDeclaredLength());
mediaPlayer.prepare();
mediaPlayer.start();
afd.close();
} catch (IllegalArgumentException e) {
Log.w("Rahul Log",e.getMessage());
} catch (IllegalStateException e) {
Log.w("Rahul Log", e.getMessage());
} catch (IOException e) {
Log.w("Rahul Log", e.getMessage());

}
}
函数拒绝调用可以正常工作,但是接受调用不能正常工作.
The function reject call is working fine but accept call is not working.
推荐答案
我的应用遇到了相同的问题.设置一些接受来电的延迟(〜3000 ms).您还需要在其他线程中调用acceptCall()
方法.
I have came across same issue for my app. Put some delay for accepting incoming call(~3000 ms). You also need to invoke acceptCall()
method in different thread as well.
请参阅如何打入电话在Android 5.0(Lollipop)中以编程方式回答?
new Thread(new Runnable() {
@Override
public void run() {
acceptCall();
}
}).start();
private void acceptCall() {
try {
// Get the getITelephony() method
Class<?> classTelephony = Class.forName(telephonyManager.getClass().getName());
Method method = classTelephony.getDeclaredMethod("getITelephony");
// Disable access check
method.setAccessible(true);
// Invoke getITelephony() to get the ITelephony interface
Object telephonyInterface = method.invoke(telephonyManager);
// Get the endCall method from ITelephony
Class<?> telephonyInterfaceClass = Class.forName(telephonyInterface.getClass().getName());
Method methodEndCall = telephonyInterfaceClass.getDeclaredMethod("answerRingingCall");
// Invoke endCall()
methodEndCall.invoke(telephonyInterface);
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
