CallLog生成器错误-安卓开发

Question

我正试图在Android Studio中实现一些假的通话记录。当我在安装了应用程序的情况下运行模拟器时，它首先显示Launcher 3已停止工作，然后当我单击add call log按钮时它显示‘不幸的是callLog应用程序已停止工作’。我认为我可能需要解析器if语句中的某些内容，因为它以红色突出显示，并显示需要用户权限的提示。来自主activity类的代码是：

    package com.example.calllogexample;

    import android.content.ContentResolver;
    import android.content.ContentValues;
    import android.net.Uri;
    import android.provider.CallLog;
    import android.util.Log;


    public class CallLogActivity {

     public void AddNumToCallLog(ContentResolver resolver ,String strNum, int type, long timeInMiliSecond) {
         while (strNum.contains("-")) {
             strNum = strNum.substring(0, strNum.indexOf('-')) + strNum.substring(strNum.indexOf('-') + 1, strNum.length());
         }
         ContentValues values = new ContentValues();
         values.put(CallLog.Calls.NUMBER, strNum);
         values.put(CallLog.Calls.DATE, timeInMiliSecond);
         values.put(CallLog.Calls.DURATION, 0);
         values.put(CallLog.Calls.TYPE, type);
         values.put(CallLog.Calls.NEW, 1);
         values.put(CallLog.Calls.CACHED_NAME, "");
         values.put(CallLog.Calls.CACHED_NUMBER_TYPE, 0);
         values.put(CallLog.Calls.CACHED_NUMBER_LABEL, "");
         Log.d("AddToCallLog", "Inserting call log placeholder for " + strNum);

         if (null != resolver) {
             resolver.insert(CallLog.Calls.CONTENT_URI, values);
         }
     }

        public void DeleteNumFromCallLog(ContentResolver resolver, String strNum) {
            try {
                String strUriCalls = "content://call_log/calls";
                Uri UriCalls = Uri.parse(strUriCalls);
                if (null != resolver) {
                    resolver.delete(UriCalls, CallLog.Calls.NUMBER + "=?", new String[]{strNum});
                }
            } catch (Exception e) {
                e.getMessage();
            }
        }

}

清单文件中manifest标签下的写入权限

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