1. Android Dynamic Request Permission

First, you need to statically apply for phone permissions in AndroidManifest.xml, otherwise you cannot dynamically apply for permissions. The following code positions cannot be misplaced (outside the application):

Then, write the logic of dynamic permission application in java code (this is the official website)

public void requestPower() {//Determine whether permission has been granted if (ContextCompat.checkSelfPermission(this, Manifest.permission. above phone permission character) != PackageManager.PERMISSION_GRANTED) { //This method returns true if the application previously requested this permission but the user refused the request. if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest. permission. above telephone permission character)) {//Here you can write a dialog box to explain to the user why you want to apply for permission, and in the dialog box confirm the key to apply for permission again. It returns false if the user selects "Don't ask again." } else { //Apply permission. The string array contains one or more permissions to apply for. 1 is the return parameter of the permission application result. You can find the application result in onRequestPermissionsResult. ActivityCompat.requestPermissions(this, new String[]{Manifest.permission. Phone characters above,}, 1); } 2. Create an AIDL file ITelephony package name must be (com.android.internal.telephony)// ITelephony.aidl package com.android.internal.telephony; / Declare any non-default types here with import statements interface ITelephony { boolean endCall(); void answerRingCall (); }3. Write java code to hang up the phone private void endCall() { try { //Get the hidden API through reflection, and get the Class object of the hidden class Class clazz = Class.forName("android.os.ServiceManager"); //Get Method object Method method = clazz.getMethod("getService", String.class); //call method to get iBinder object IBinder ibinder = (IBinder) method.invoke(null, Context.TELEPHONY_SERVICE); ITelephony iTelephony = ITelephony.Stub.asInterface(ibinder); iTelephony.endCall();//End call } catch (Exception e) { e.printStackTrace(); } }

Remember to add phone privileges dynamically! Otherwise, hanging up the phone would not be possible.
