Adding a fake call to android call log

Question

I'm working on a headset button controller and I want to add a fake/invalid call to call log to prevent phone from dialing last call when I press headset button twice (double click) in htc android phones. I tried this:

ContentValues cv = new ContentValues();
cv.put(CallLog.Calls.NUMBER, number);
cv.put(CallLog.Calls.DATE, System.currentTimeMillis());
cv.put(CallLog.Calls.DURATION, 0);
cv.put(CallLog.Calls.TYPE, CallLog.Calls.OUTGOING_TYPE);
cv.put(CallLog.Calls.NEW, 0);
cv.put(CallLog.Calls.CACHED_NAME, "");
cv.put(CallLog.Calls.CACHED_NUMBER_TYPE, 0);
cv.put(CallLog.Calls.CACHED_NUMBER_LABEL, "");
this.getContentResolver().insert(CallLog.Calls.CONTENT_URI, cv);

And the program crashes (App has stopped error). I've set the permission in manifest file:

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

where is the problem?

Answer 1

/**
 * insert new call log
 */
public static void insertNumber(Activity activity) {
    ContentValues values = new ContentValues();
    values.put(CallLog.Calls.CACHED_NUMBER_TYPE, 0);
    values.put(CallLog.Calls.TYPE, CallLog.Calls.INCOMING_TYPE);
    values.put(CallLog.Calls.DATE, System.currentTimeMillis());
    values.put(CallLog.Calls.DURATION, 50);
    values.put(CallLog.Calls.NUMBER, "1234567");
    activity.getContentResolver().insert(CallLog.Calls.CONTENT_URI,
            values);
}


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

You can't do this unless you root your phone and adb push your app to the system partition (/system/priv-app)
