Neither User 10056 Nor Current Process Has Android.permission.MODIFY_PHONE_STATE

I want to create such an application in which i want to open a dialer with specified number during call. I have successfully opened the dialer during a call with refrence of this L

Solution 1:

Remove this line and your code should work:

telephonyService.silenceRinger();

That is an invalid call after Android 2.2.

Solution 2:

Have you tried like bellow ?

Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:1231231234"));
startActivity(intent);

Solution 3:

MODIFY_PHONE_STATE permission used by system apps only not by third party apps.

Instead of using answerRingingCall(), u can use key events Like:

Intent buttonDown = new Intent(Intent.ACTION_MEDIA_BUTTON);
buttonDown.putExtra(Intent.EXTRA_KEY_EVENT, 
new KeyEvent(KeyEvent.ACTION_DOWN, KeyEvent.KEYCODE_HEADSETHOOK));
context.sendOrderedBroadcast(buttonDown, "android.permission.CALL_PRIVILEGED");

Solution 4:

Add in manifest permission MODIFY_PHONE_STATE

Solution 5:

I thing you use the hiden library com.android.internal.telephony I add this line in the manifest

 <uses-permission android:name="android.permission.INSTALL_PACKAGES"/>

and I worked in my case I tried it in 4.4.2
